Seismology is the study of earthquakes and seismic waves. Seismic waves are vibrations generated by earthquakes or explosions that propagate within the Earth. A seismograph records the magnitude of ground oscillations caused by seismic waves. There are two main types of seismic waves - body waves that travel through the Earth's interior and surface waves that travel along the Earth's surface. Body waves include P-waves and S-waves, while surface waves include Love waves and Rayleigh waves.

Seismic Waves by Saseetharan D
Seismic waves are caused by the sudden breaking of rock within the Earth or explosions. There are two main types of seismic waves: body waves and surface waves. Body waves include P-waves and S-waves, while surface waves include Love waves and Rayleigh waves. Rayleigh waves cause the ground to roll up and down and side to side as they move along the surface, making them responsible for much of the shaking felt during earthquakes.
Seismic waves
Seismic waves are energy transferred within the Earth's interior from one area to another. There are two main types of seismic waves: body waves, which can travel through the Earth's interior, and surface waves, which travel along the Earth's surface. Body waves include P-waves and S-waves, where P-waves are compressional and the fastest, and S-waves are slower shear waves. Surface waves include L-waves and Rayleigh waves, where L-waves move horizontally and Rayleigh waves move both vertically and horizontally in a rolling motion.
Seismic waves - Elshaima
There are three main types of seismic waves: P waves, S waves, and L waves. P waves are the first to arrive and move side to side, while S waves follow and move up and down. L waves, also known as surface waves, are the largest and come last, moving in a circular motion. Seismic waves are caused by the breaking of rock in earth's plates and are recorded by seismographs.
Seismic waves
1. Seismic waves are energy waves generated by earthquakes that travel through the earth. There are two main types of seismic waves: body waves and surface waves.
2. Body waves include P-waves and S-waves. P-waves are faster primary waves that can travel through solid and liquid materials. S-waves are slower secondary waves that only travel through solids.
3. Surface waves include Love waves and Rayleigh waves. Love waves cause side-to-side motions while Rayleigh waves cause up and down rolling motions. Surface waves do the most damage to structures during an earthquake.

1) Earthquakes are caused by the sudden release of stored elastic energy in the Earth's crust. They generate different types of seismic waves that propagate outward from the earthquake focus.
2) The location and type of earthquake is determined by the surrounding tectonic environment. Convergent plate boundaries experience deep earthquakes along subduction zones, while divergent and transform boundaries have shallower quakes.
3) Earthquake magnitude is measured on different scales but all aim to characterize the energy released by the quake. Intensity scales describe perceived shaking and damage at a given location.
earthquakes
Earthquakes are caused by the sudden release of energy from the breaking of rocks deep in the earth. The elastic rebound theory explains how stress builds up in rocks until it exceeds the rocks' strength, causing rupture and the release of seismic waves. The focus is the point where faulting begins underground, and the epicenter is the point directly above on the surface. Most earthquakes occur along plate boundaries and are mapped using seismic wave arrival times at multiple stations. Earthquake size is measured by both intensity scales based on damage, and by magnitude scales measuring the total energy released.
Disaster management
Body waves, including P and S waves, travel through solids, liquids, and gases. P waves are faster compressional waves, while S waves are slower shear waves that only travel through solids. Surface waves like R and L waves travel along or below the surface. The difference in arrival times of seismic waves at multiple seismograph stations can be used to locate an earthquake's epicenter by drawing circles around each station. Both the intensity of ground shaking and magnitude, measured on the Richter scale, are used to measure an earthquake's size and strength, with magnitude being independent of intensity. Earthquakes can cause ground shaking and damage that increases in poorly consolidated rock. While some monitoring and studies aim to predict or control qu

The document discusses different types of seismic waves. There are two types of body waves: P-waves which are compressional waves that vibrate in the direction of propagation, and S-waves which are shear waves that vibrate perpendicular to the direction of propagation. There are also two types of surface waves: Love waves which cause side-to-side motion like a snake, and Rayleigh waves which cause a rolling motion like ocean waves. The document provides information on the velocities and motions of each type of wave.

Sumatra Earthquake
An 8.4 magnitude earthquake occurred off the coast of southern Sumatra on September 12, 2007, followed by a 7.9 magnitude aftershock. This caused 25 deaths and 161 injuries. Seismograph recordings from stations in Washington state, like the one near the LIGO detector, detected P and S waves from the earthquakes around 21 minutes after the initial quake, matching the expected travel times. This provides evidence that the gravitational waves detected by LIGO at this time were caused by this Sumatra earthquake event.

Earthquakes
Earthquakes are caused by the sudden release of energy from the breaking of rocks deep underground, usually along fault lines. The point where faulting begins is called the focus or hypocenter. Waves of energy radiate out from the hypocenter, and the point directly above on the surface is called the epicenter. Most earthquakes occur along plate boundaries and cause damage through ground shaking and secondary effects like tsunamis or landslides. While earthquake prediction remains challenging, monitoring seismic activity and studying faults can help assess earthquake risks.

Seismic waves radiate out from the hypocenter, and by measuring their arrival times at different locations, seismographs can locate the epicenter. The size of an earthquake is measured by both its intensity, which describes damage, and its magnitude, which measures the total energy released. Major earthquakes can have devastating economic and societal impacts through ground shaking and secondary effects like tsunamis or landslides.
4.2 recording earthquakes
Scientists measure the magnitude of an earthquake using the Richter scale, which quantifies the amount of energy released by the earthquake based on the amplitude of seismic waves recorded by seismographs. The larger the amplitude, the higher the magnitude.
Stress And Energy Waves
Stress builds up in the Earth's crust at plate boundaries and can cause rocks to fold, forming mountains, or break along faults, causing earthquakes. During an earthquake, seismic waves transmit energy through the Earth. Primary waves are body waves that travel fastest and arrive first, moving particles forward and backward. Secondary waves are also body waves that arrive second, moving particles side to side. Love and Rayleigh waves are slower surface waves that cause ripples at the Earth's surface.

It notes that while the ridge is offset by transform faults, the Charlie-Gibbs Fracture Zone is one of the largest. It then provides details on a magnitude 7.1 earthquake that occurred in the Northern Mid-Atlantic Ridge in 2015, including the arrival times of seismic waves at a recording station over 6,000 km away.
Earthquakes
An earthquake is caused by the release of energy stored in rocks that are sliding past one another deep underground. When the rocks finally slip, they snap back into position, releasing this stored energy in the form of waves that travel outward in all directions through the earth. There are different types of earthquake waves that move the ground in various ways and travel at separate speeds, allowing scientists to determine the distance to the earthquake's origin. Earthquake waves can travel great distances depending on the magnitude of the quake, sometimes going around the entire planet multiple times for very large seismic events.

What are earthquakes with animation
Earthquakes are caused by the sudden release of energy from faulting or breaking of rocks deep within the earth. They produce seismic waves that radiate out from the hypocenter, or focus point, where the rupture occurs. The epicenter is the point on the surface directly above the hypocenter. Most earthquakes occur along plate boundaries and are more destructive in areas with poorly consolidated rock. Seismographs can be used to locate an epicenter by measuring the difference in arrival times of seismic waves at three stations. While some precursors and patterns have been observed, earthquakes remain difficult to predict and control with complete accuracy.

Earthquakes
An earthquake is caused by a sudden release of energy in the Earth's crust that creates seismic waves. The elastic rebound theory explains how rocks slowly accumulate energy from crustal movements until their strength is exceeded, causing them to break and fault. The hypocenter is where the earthquake initiates underground, while the epicenter is the point directly above on the surface. Seismic waves, including P, S, R and L waves, are detected by seismographs and used to locate the epicenter at the intersection of distance circumferences from multiple stations. Earthquakes are measured on both the Mercalli and Richter scales.
earthquake prediction
While scientists have made progress in understanding earthquakes and calculating probability of future quakes, earthquake prediction remains challenging. Deterministic prediction aims to specify timing, location and magnitude of the next quake, but no method has proven successful yet. Statistical prediction calculates probability based on scientific data, like a 67% chance of a major quake in the San Francisco Bay area within 30 years. Earthquake signals are difficult to detect as processes occur deep underground, but scientists continue working to develop reliable prediction methods that could help save thousands of lives.

The document discusses earthquakes, including what causes them, how they are measured, and some devastating examples. Earthquakes occur when tectonic plates shift underground, causing shaking and damage. They are most common near mountains where tectonic plates meet. Earthquakes are measured using the Richter scale and seismometers, which detect ground vibrations. Some catastrophic quakes discussed include the 2004 Indian Ocean earthquake, which triggered a tsunami killing over 230,000 people, and the 2010 Chile earthquake, an 8.8 magnitude quake felt by most of Chile's population.
Earthquakes
Earthquakes are caused by the abrupt release of energy in the Earth. They can be measured using the Richter scale and recorded by seismographs. Seismic waves, including P, S, and surface waves, propagate out from the earthquake source and cause damage depending on their magnitude. Effects of earthquakes include destruction of buildings and infrastructure, soil damage, landslides, and tsunamis. Earthquake data provides information about the composition and structure of Earth's interior layers. Notable historical earthquakes include the 2011 earthquake in Lorca, Spain and the 2011 Tōhoku earthquake and tsunami in Japan.

Earthquakes release energy through seismic waves that originate from a focus underground and spread out from the epicenter on the surface above the focus. There are three main types of seismic waves - P waves that are fastest and can pass through solids, liquids, and gases; S waves that are slower and can only pass through solids; and surface waves that move along the Earth's surface and cause the most damage. Scientists use seismographs to constantly record ground movements and then locate earthquakes by using the differences in arrival times of P and S waves at three or more seismic stations to determine the distance from each station to the epicenter.

An earthquake is caused by a sudden release of energy along a fault line in the Earth's crust. Seismologists study earthquakes and the seismic waves that are produced, including surface waves and body waves. Surface waves travel along the Earth's surface and include Love waves and Rayleigh waves, which cause horizontal and elliptical ground motions, respectively. Body waves can travel through the Earth's interior layers and include faster P waves and slower S waves, with P waves causing compressional motions and S waves causing side-to-side shaking motions.
Earthquake Resistant Design-Introduction.pptx
Seismology is the study of earthquakes and seismic waves. When tectonic plates interact through subduction, rifting, or transform faults, elastic strain builds along fault lines until the rocks rupture, releasing seismic waves. P waves and S waves are the main types of seismic body waves that travel through the earth's interior. Surface waves such as Rayleigh and Love waves travel near the surface and can be very destructive. Modern seismographs precisely record seismic wave arrivals to locate earthquake epicenters through analysis of travel times and velocities of P and S waves.

Earthquakes have been recorded throughout history. Seismology is the study of earthquakes and seismic waves. There are different types of seismic waves that move in different ways through the earth, including body waves like P waves and S waves, and surface waves like Love waves and Rayleigh waves. The focus is the point where rocks start to fracture during an earthquake, and the epicenter is the point directly above the focus on the earth's surface. Earthquakes can be shallow or deep, and commonly occur at plate boundaries. It is important to have emergency plans and supplies to stay safe during and after an earthquake.
Seismic Waves
Seismic waves are waves of energy caused by the sudden breaking of rock within the Earth or explosions. There are two main types of seismic waves: body waves and surface waves.

An earthquake refers to the shaking of the earth's surface caused by a sudden release of energy within the earth's crust. This energy is released at the earthquake focus and originates seismic waves. The point on the surface directly above the focus is the epicenter. P waves and S waves travel outward from the focus, and scientists can use the difference in their arrival times recorded by seismographs to determine the distance to the epicenter. The 1960 Great Chilean Earthquake, measuring 9.5, was the strongest of the 20th century and generated a tsunami that spread across the Pacific Ocean.
Sesimic waves
Seismic waves are elastic waves generated by earthquakes or explosions that travel through the earth. There are two main types of seismic waves: P-waves and S-waves. P-waves are compressional waves that move faster through solid earth, while S-waves are slower shear waves that can only travel through solids. Seismic waves are used to study earthquakes and also to explore underground for oil and natural gas reservoirs.

The most devastating earthquake in Philippine history occurred in 1976 in Mindanao, causing over 8,000 deaths. Scientists have warned that a powerful earthquake called the "Big One" could strike the West Valley Fault near Manila, potentially killing 34,000 people. Earthquakes are caused by the sudden release of built-up energy in the Earth's crust from plate tectonics and fault movements, producing seismic waves.

An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. Faults are fractures in rock where one side has moved relative to the other. Seismic waves, detected by seismographs, include P-waves, which are longitudinal, and S-waves, which are transverse. Surface waves travel near the Earth's surface and can be the most destructive. The magnitude of most quakes is measured on the Richter scale invented in 1934 by Charles Richter. During quakes, it is safest to drop, cover, and hold on until the shaking stops.
Types of Seismic Waves
Seismic waves are caused by earthquakes and volcanic eruptions and travel through the Earth, imparting acoustic energy. There are two main types of seismic waves - body waves that travel beneath the surface and surface waves that travel along the surface. Body waves include primary P-waves and secondary S-waves that travel faster and slower respectively. Surface waves include Rayleigh and Love waves that cause the most destruction and travel the slowest. Earthquakes are usually caused by a sudden release of built-up pressure when rocks underground break along a fault.

When an earthquake occurs, energy is released in the form of seismic waves that travel through the Earth. There are two types of seismic waves: body waves and surface waves. Body waves travel through the interior of the Earth and include P waves and S waves. P waves are the fastest seismic waves while S waves move more slowly and can only pass through solids. Surface waves travel along the top of the Earth's crust and cause more damage than body waves.

Chapter IV- Thesis (Sample).pptx
This chapter summarizes the results of a study about the causes of poor grades among elementary school students. It finds that the majority of respondents do not regularly study at the same time each day and sometimes spend more time playing than studying. The most disliked subject was found to be Araling Panlipunan, while the most liked subjects were Science and Math. The chapter concludes that poor study habits after school and spending too much time on games and gadgets instead of schoolwork can contribute to poor grades. It recommends that schools, parents, and students work together to help students prioritize their studies.
Atoms and Molecules.pptx
- Elements are pure substances made of one type of atom, while compounds are pure substances made of two or more elements chemically bonded together.
- Atoms are the basic unit of elements and consist of a nucleus containing protons and neutrons surrounded by electrons in shells of different energy levels.
- Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
- Molecules are the smallest particle of a substance that contains one or more bonded atoms and has the chemical and physical properties of that substance.
- Dalton's atomic theory proposed that matter is made of atoms that cannot be created, destroyed, or converted between elements, and that compounds form from atoms combining in
Responsible Parenthood.pptx
The document discusses the Reproductive Health Law in the Philippines which guarantees universal access to contraception, sex education, and maternal care. It mandates the government to promote effective family planning methods and integrate family planning into anti-poverty programs. The law also requires employers to guarantee reproductive health rights and the government to ensure availability of related healthcare services. Responsible parenthood is defined as parents guiding and providing for their children's needs through education, nutrition, healthcare and more. Family planning allows couples to control the number, spacing and timing of children through birth control techniques.
Ideal Gas Law.pptx
The document discusses respiration and how it works. As we inhale, the diaphragm moves down which reduces pressure in the lungs and causes air to rush in. As we exhale, the diaphragm pushes up increasing pressure in the lungs and forcing the air out. Breathing involves small pressure differences between the inside and outside of the lungs. A normal breath contains about 0.21 moles of air, which is enough to sustain life.

Philippine AIDS Prevention and Control Act of.pptx
The document summarizes two key Philippine laws related to health:
1) The Philippine AIDS Prevention and Control Act of 1998 (RA 8504) which aims to prevent and control the spread of HIV/AIDS through public education campaigns, protecting human rights of those infected, and ensuring access to health services.
2) The National Blood Services Act of 1994 (RA 7719) which promotes voluntary and safe blood donation through establishing a national blood transfusion network, regulating blood banks, and educating the public on the importance of voluntary donation over commercial sale.
Interactions among Living Things in Mangrove Swamps.pptx
Mangroves are plants that live in coastal tidal areas between land and sea. They are important parts of coastal ecosystems. The Philippines has over 50% of the world's mangrove species diversity. Mangroves have complex root systems and pneumatophores that allow them to live in saline waters and interact with other organisms in the mangrove swamp ecosystem through relationships like mutualism, commensalism, parasitism, competition, and predation. Mangroves are important to protect and conserve because they provide habitat for many species, contribute to marine growth, help fight climate change, stabilize coastlines, and provide resources for humans.
Proving that a Quadrilateral is a Parallelogram.pptx
A quadrilateral is a parallelogram if both pairs of its opposite sides are congruent. This is because if two triangles are congruent by CPCTC (corresponding parts of congruent triangles are congruent), then their corresponding angles and sides are also congruent. To prove opposite sides of a parallelogram are congruent, show the parallelogram has two sets of congruent triangles formed by the sides.
Environment Awareness Act and Traditional and Alternative Medicine Act.pptx
This document summarizes two national laws related to health in the Philippines:
The National Environmental Awareness and Educational Act of 2008 promotes environmental conservation and education. It integrates environmental education into school curriculums through collaboration between government agencies.
The Traditional and Alternative Medicine Act of 1997 created the Philippine Institute of Traditional and Alternative Health Care to advance and fund traditional healthcare. It aims to improve healthcare delivery and integrate traditional medicine into the national system. The law also seeks to protect indigenous communities' ownership of traditional medical knowledge and ensure compensation if outsiders use this knowledge commercially.
Maternal Health Concerns.pptx
Complications during pregnancy can affect the health of both the mother and baby. It is important for women to receive healthcare before, during, and after pregnancy to address any health problems. Before pregnancy, women should discuss their medical history and treatment with their doctor, as some medications could be harmful. During pregnancy, women may experience conditions like anemia, infections, gestational diabetes, or mental health issues. After giving birth, many women experience postpartum depression, as hormonal changes can trigger depressive symptoms. Proper healthcare at all stages of pregnancy can help ensure the health of both mother and baby.
Combined Gas Law.pptx
The document discusses the combined gas law, which incorporates Charles' law, Boyle's law, and Gay-Lussac's law. It provides the equations for each individual gas law and the combined gas law. Two examples are shown applying the combined gas law to calculate changes in pressure, temperature, and volume. The final activity asks how many 5L balloons can be filled from a starting gas quantity.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Seismic waves
- 2. Seismology is a branch of geophysics which concerned with study of earthquakes and transmission and dissemination of seismic waves within the Earth. Seismic waves are vibrations that are usually generated by earthquakes or explosions and are propagated within the Earth or along its surface.
- 3. A seismograph records varying magnitude of ground oscillations caused by seismic waves that travel from their point of origin through the Earth or along its surface. Magnitude is the measure of the energy released at the source of the earthquake and it is expressed using the Richter scale. In 1935, Charles F. Richter of the California Institute of Technology developed a mathematical device to measure and compare the magnitude of earthquakes.
- 5. Types of Seismic Waves A. Body Waves – it travel through the Earth’s mantle and crust. 1. primary waves (also called P waves) – are the fastest of all the seismic wave types and produce longitudinal movement (in the same direction of the wave propagation). 2. S wave or secondary waves (also called shear waves) – moves through the body of the earth but are slightly slower than P waves and produced perpendicular wave motion, unlike P waves, cannot travel through liquid. -
- 6. B.Surface Waves 1. Love Waves (1911, Augustus Edward Hough Love) – Move the ground from side to side in a horizontal plane but at right angles to the direction of propagation. The horizontal shaking of Love waves is damaging to the foundations of structures. 2. Rayleigh Waves (1885, Lord Rayleigh) – this wave moves like rolling ocean waves. In addition it moves both vertically and horizontally in a vertical pane pointed in the direction in which the waves are travelling.
