This document provides information about earthquakes, including what causes them, where they occur, and how they are measured. It discusses how tectonic plate movement can build stress along faults, causing rocks to break and release energy in the form of seismic waves. There are three main types of faults and three types of seismic waves. Earthquakes are located using seismographs to measure the arrival times of P and S waves at multiple stations, then triangulating the epicenter where the circles intersect. The largest earthquakes are measured on the Richter scale.
1) Earthquakes are caused by the release of energy along faults in the Earth's crust due to the buildup of pressure.
2) There are three main types of seismic waves that radiate out from the earthquake focus: primary (P) waves, secondary (S) waves, and surface waves.
3) Earthquakes are measured using the Richter Scale, which quantifies the amount of energy released by the earthquake. The strongest earthquake ever recorded was magnitude 9.5.
Earthquakes are caused by the sudden release of energy in the Earth's crust that generates seismic waves. There are three main types of faults that cause earthquakes by movement of tectonic plates. Scientists can measure the location and magnitude of earthquakes using seismographs to detect primary, secondary, and surface seismic waves, then calculating distances based on differences in arrival times of P and S waves at multiple locations. Large earthquakes can trigger tsunamis by displacing large volumes of water.

Earthquakes are caused by the sudden release of built-up strain energy along fault lines in the Earth's crust. Faults occur at boundaries between tectonic plates where the plates slide past each other. There are different types of faults such as normal, reverse, strike-slip and oblique. Earthquake waves called seismic waves radiate out from the hypocenter or focus of the earthquake. P-waves and S-waves are two types of seismic waves that travel through the Earth. Surface waves including Rayleigh and Love waves cause the most damage during an earthquake. Factors like magnitude, distance from the epicenter, local geology can influence earthquake intensity.

There are three main types of seismic waves that travel through the Earth during an earthquake:
1. P-waves are compressional body waves that move through solid rock and fluids.
2. S-waves are slower shear body waves that only move through solid rock.
3. Surface waves like Rayleigh and Love waves move along the Earth's surface and can cause significant damage.
Seismographs are used to measure and record these seismic waves to determine the location and magnitude of earthquakes.
This document appears to be a student project report on the study of earthquakes. It includes sections on the history of earthquake research, what causes earthquakes, how their locations and magnitudes are measured, the different types of seismic waves, the impacts of earthquakes, and approaches to predicting and controlling them. The project received certification from the University of Mumbai professors after satisfactory completion by the six listed students.
The document discusses earthquakes and related topics in three main sections. Section one describes how earthquakes are caused by movement along tectonic plate boundaries and outlines the different types of seismic waves generated by earthquakes. Section two explains how earthquakes are measured, located and recorded using seismographs. Section three discusses the damage earthquakes can cause to buildings and properties from ground shaking and liquefaction. It also describes tsunamis and provides safety tips for earthquake preparedness.
Earthquakes occur due to the buildup and sudden release of energy along fault lines in the Earth's crust. When pressure becomes too great, the plates jerk past one another causing violent shaking at the epicenter and releasing seismic waves that spread outwards. The three main types of faults are normal, reverse, and strike-slip, which control how the plates move during an earthquake. Understanding earthquake hazards and being prepared can help reduce risks to safety when they occur.

The document discusses earthquakes, including what causes them, how they are measured, and their effects. It defines earthquakes as occurring along faults in the earth's crust due to a buildup of pressure. When the pressure is released, seismic waves are generated and cause shaking and damage at the epicenter and surface. Earthquakes are measured by both magnitude scales and intensity scales that indicate their strength and damage. Major earthquakes can cause widespread destruction through ground shaking and secondary effects like tsunamis and landslides.
1) Earthquakes occur along fault lines in the earth's crust due to the buildup and release of stress as tectonic plates shift.
2) There are three main types of faults that can form from different types of stress: normal faults from tension, reverse faults from compression, and strike-slip faults from shear stress.
3) When stress is released along a fault, seismic waves are generated including faster P and S body waves and slower surface Love and Rayleigh waves.
The document discusses earthquakes, including what they are, their causes, how they are measured, and their effects. It states that earthquakes are caused by the rapid release of energy from geological faults or other events like volcanic activity. They are measured using seismographs which record seismic waves, and their epicenters can be located by using the differences in arrival times of waves at multiple seismograph stations. The size and strength of earthquakes are measured objectively using magnitude scales or subjectively using intensity scales based on the observed damage.
Earthquakes occur when tectonic forces cause rocks underground to break, releasing energy in the form of seismic waves. The focus is the point where the rocks break, and the epicenter is the point directly above on the surface. There are three main types of seismic waves - P waves, which move particles back and forth; S waves, which move particles at right angles; and surface L waves, which cause the most damage. We measure the location and magnitude of earthquakes using seismographs to detect and measure the amplitude of the different wave types.

Design Steps for Earthquake Resistant StructuresIshan Garg
This document provides information about earthquakes and their causes. It discusses what earthquakes are, how they are caused by the movement of tectonic plates along faults, and defines key terms like epicenter. It describes the interior structure of the Earth and plate tectonics. Safety procedures during earthquakes are outlined. The types of earthquake waves and how they are measured on seismographs is explained. Finally, it discusses earthquake magnitude scales and seismic zoning in India.
P and S waves travel through the earth's interior during earthquakes, while surface waves travel along the surface. By measuring the time difference between P and S wave arrivals on seismograms from multiple locations, scientists can triangulate the earthquake's epicenter. The location and magnitude of earthquakes are determined through analyzing seismic wave propagation and amplitudes, with magnitude quantified using the Richter scale. Modern understanding of plate tectonics explains earthquake occurrence at plate boundaries due to built-up stress being released suddenly.
1) Earthquakes are caused by the sudden release of energy in Earth's crust from tectonic plate movement.
2) Seismic waves from earthquakes travel outward from the focus, with P and S waves detected by seismographs to locate the epicenter.
3) The magnitude scale is used to measure earthquake strength based on seismic wave amplitude, while intensity scales describe damage levels at a location.
Earthquakes occur when tectonic forces cause rocks underground to break, releasing seismic waves. The focus is where the rocks break, and the epicenter is the point directly above on the surface. Different types of faults are caused by tension, compression, and shear forces. Earthquakes are measured by their magnitude using the Richter scale and by their intensity of shaking. Locating the epicenter involves measuring seismic wave arrival times at different stations. Earthquake dangers include falling objects, fires, tsunamis, liquefaction, and landslides.
An earthquake occurs due to a sudden slip or movement along a fault line in the Earth's crust. This movement releases built-up energy in the form of seismic waves that travel outward from the hypocenter or focus of the earthquake. The intensity of shaking and damage is greater near the epicenter, which is the point on the surface directly above the focus. Earthquake magnitude measures the energy released while intensity scales describe the observed effects on people and structures. Large earthquakes can sometimes generate tsunamis when the sudden movement of underwater faults displace large volumes of water.

The document discusses earthquakes, including what causes them, how they are measured, their effects, and statistics on major earthquakes around the world. Specifically, it defines an earthquake as rapid shaking caused by the sudden release of energy along fault lines. It describes the movement of tectonic plates and how this results in earthquakes. Key points covered include earthquake magnitude scales, the different types of seismic waves generated, and data on some of the largest earthquakes by magnitude and their impacts.
Earthquakes are the shaking, rolling or sudden shock of the earth’s surface. They are the Earth's natural means of releasing stress. Earthquakes can be felt over large areas.
Earthquakes cannot be predicted, although scientists are working on it.
Earthquakes are caused by the sudden release of built-up energy along fault lines in the earth's crust. They begin at a focal point below the surface and radiate seismic waves outward. The location directly above the focus on the surface is called the epicenter, and it is where the most damage typically occurs. Earthquakes are measured using the Richter scale, which quantifies the amount of energy released. Areas near tectonic plate boundaries and fault lines are more prone to earthquakes.
Earthquakes are caused by the sudden release of built-up energy along fault lines in the earth's crust. They begin at a focal point below the surface and radiate seismic waves outward. The location directly above the focus on the earth's surface is called the epicenter, which is important for understanding where damage and shaking will be strongest. Earthquakes are measured on the Richter scale, which quantifies the amount of energy released. Areas near fault lines are more susceptible to earthquakes, and the severity of shaking and damage depends on the quake's magnitude, distance from the epicenter, and local geology.
An earthquake occurs when energy is rapidly released along a fault line. The point where the rock breaks is called the focus, and the point directly above it on the earth's surface is the epicenter. Seismic waves carry energy away from the focus, including P waves and S waves. P waves are compressional and can travel through all material, arriving first, while S waves are transverse and can only travel through solids, arriving second. Locating an earthquake's epicenter requires detecting the seismic waves with seismographs at three different recording stations and finding the point where the circles around each station intersect. Underwater earthquakes can create massive tsunamis by displacing large volumes of water.

radiating _____seismic waves___ that is caused
by the slip. ___Volcanic Activity____, or other
geologic processes, may cause stress changes in
the earth that can also result in an earthquake.
11. The earth’s crust is constantly
experiencing pressure from forces
within and around it. This pressure
builds up over time, and eventually
causes the crust to break. This
becomes a fault.
Let’s experience it…
12. Faults are divided into three main groups:
Normal fault - when two plates are moving apart
and one side of the fracture moves below the
other; (caused by tension forces!)
Reverse fault - when two plates collide and one
side of the fracture moves on top of another;
(caused by compression forces!!)
Strike-slip - when two plates slide past each
other. (caused by shear forces!)
14. An earthquake begins along a fault (a
crack in the earth’s surface) at a point
called the focus.
Directly above the focus is a point on
the earth’s surface called the epicenter.
16. Seismologists have stations all over the world
that continuously collect information about
earthquakes. This kind of information can help
scientists figure out where larger, more
destructive earthquakes may strike by mapping
out the location of smaller ‘quakes. They also
get a greater understanding of the changes the
earth’s crust makes as the earthquakes occur.
How do they do this???
17. When the fault ruptures with a sudden movement
energy is released that has built up over the
years. This energy is released in the form of
vibrations called 'seismic waves'… earthquakes!
It is actually when these seismic waves reach the
surface of the earth that most of the destruction
occurs, which we associate with earthquakes.
18. Parts of the Earthquake
• The energy spreads outward in all directions as
vibrations called ____seismic waves_____.
• The _focus____ of the earthquake is the point in
the crust, or mantle, where energy is released.
• The _epicenter___ is the point on Earth’s surface
directly above the focus; energy that reaches the
surface is greatest at this point.
19. Focus – point inside the Earth where an
earthquake begins
Epicenter – point on Earth’s surface above focus
21. WHAT CAUSES EARTHQUAKES?
• Used to describe both sudden slip on a fault,
and the resulting ground shaking and radiated
seismic energy caused by the slip
• Caused by volcanic or magmatic activity,
• Caused by other sudden stress changes in
the earth.
22. What causes earthquakes?
• Tectonic plates move past each other causing
stress. Stress causes the rock to deform
24. Cause of Earthquakes
What Causes an Earthquake?
• An aftershock is a small earthquake that
follows the main earthquake.
• A foreshock is a small earthquake that often
precedes a major earthquake.
Aftershocks and Foreshocks
25. Earthquakes can also cause landslides, sudden
eruptions as in the case of a hot lava flow from a
volcano or giant waves called tsunamis. Sometimes new
land mass are also formed. Such earthquakes are
attributed with the creation of the greatest undersea
mountain range and the longest land mountain range.
39. Where Do Earthquakes Occur and How Often?
~80% of all earthquakes occur in the circum-Pacific belt
– most of these result from convergent margin activity
– ~15% occur in the Mediterranean-Asiatic belt
– remaining 5% occur in the interiors of plates and on
spreading ridge centers
– more than 150,000 quakes strong enough to be felt are
recorded each year

46. INTRODUCTION
• IN A POP AND LOCK DANCE MOVE,
STUDENTS WILL DEMONSTRATE THE
3 TYPES OF SEISMIC WAVES
47. SEISMIC WAVES
• _SEISMIC WAVES___ are waves
generated by an earthquake that travel
through the Earth. These waves can cause
the ground to move forward, backward,
up, down, and even to ripple. Seismic
Waves are generated at the __SAME___
time but move in different ways, and at
different speeds.
51. Earthquake Waves
8.2 Measuring Earthquakes
Body Waves
• P waves
• Identified as P waves or S waves
- Have the greatest velocity of all
earthquake waves
- Are push-pull waves that push (compress) and
pull (expand) in the direction that the waves
travel
- Travel through solids, liquids, and gases
52. PRIMARY (P) WAVE
• Move out from the earthquake focus, the
point where the energy is released
• Travel the fastest of the three waves
• Move through solid and liquid layers of
Earth (it also can move in gas)
• Push and pull rock creating a back-and-
forth motion in the direction the wave is
moving (longitudinal wave)
53. Primary Waves (P Waves)
• A type of seismic wave that compresses
and expands the ground
• The first wave to arrive at an
earthquake
http://daphne.meccahosting.com/~a0000e89/insideearth2.htm
54. Earthquake Waves
8.2 Measuring Earthquakes
Body Waves
• S waves
- Seismic waves that travel along Earth’s outer
layer
- Slower velocity than P waves
- Shake particles at right angles to the direction
that they travel
- Travel only through solids
A seismogram shows all three types of
seismic waves—surface waves, P
waves, and S waves.
55. Secondary Waves (S Waves)
• Move out from the earthquake focus
• Move slower than primary waves
• Can only move through solid rock
• Move at right angles to primary waves
causing rocks to move up and down and
side to side (transverse wave)
56. Secondary Waves (S Waves)
• A type of seismic wave that moves the
ground up and down or side to side
http://daphne.meccahosting.com/~a0000e89/insideearth2.htm
57. Body Waves: P and S waves
• Body waves
– P or primary waves
• fastest waves
– travel through solids,
liquids, or gases
• compressional wave,
material movement is
in the same direction
as wave movement
– S or secondary waves
• slower than P waves
• travel through solids
only
• shear waves - move
material
perpendicular to
wave movement
60. SURFACE WAVES
• Form when P and S waves reach the surface
• Can cause the ground to shake making rock sway
from side to side and roll like an ocean wave
• These waves cause the most destruction
• They move back and forth and in a rolling motion
along the surface
• They release all of the energy of the earthquake
61. Surface Waves: R and L waves
• Surface Waves
– Travel just below or along the ground’s surface
– Slower than body waves; rolling and side-to-side
movement
– Especially damaging to buildings
62. Surface Waves
• Move along the Earth’s surface
• Produces motion in the upper crust
– Motion can be up and down
– Motion can be around
– Motion can be back and forth
• Travel more slowly than S and P waves
• More destructive
66. • Scientists use the principle that the speed and
direction of a seismic wave depends on the
material it travels through. Because of the
behavior of these different waves, scientists have
indirect evidence for the solid inner core and
liquid outer core of Earth; because earthquake
waves travel faster through the mantle than
through the crust, scientists know that the mantle
is denser than the crust.
70. Measuring Earthquakes
• The movement of materials in the __outer_
core (which is a liquid) of the Earth is
inferred to be the cause of Earth’s
_magnetic field___. A compass needle
will align with the lines of force of Earth’s
magnetic field. __Iron__ and _Nickel__
are metals that easily magnetize, and are
inferred to be the metals in Earth’s core.
71. Measuring Earthquakes
• The energy spreads outward in all directions as
vibrations called ___Seismic Waves____. Seismic
waves can be measured and recorded by a
____seismograph_______.
• __Seismographs______ are instruments or a
device that detects and records seismic or
earthquake waves. It measures the vertical ground
motion and the horizontal ground motions (N-S/E-
W). It also traces wave shapes onto paper and
translates waves into an electronic signal.
72. Measuring Earthquakes
• The vibration record, called a seismogram, looks
like jagged lines on paper. Seismograms are
traces of amplified, electronically recorded ground
motion made by seismographs.
• Measuring the time between the arrival of the P
and S waves determines the distance between the
recording seismograph and the earthquake
epicenter.
73. Earthquake Waves
Measuring Earthquakes
Seismographs are instruments that
record earthquake waves.
Seismograms are traces of amplified,
electronically recorded ground motion
made by seismographs.
78. How is an Earthquake’s Epicenter Located?
Seismic wave behavior
– P waves arrive first, then S waves, then L and R
– Average speeds for all these waves is known
– After an earthquake, the difference in arrival times at a
seismograph station can be used to calculate the distance
from the seismograph to the epicenter.
79. Determining the location of an earthquake
First, distance to earthquake is determined.
1. Seismographs record seismic waves
2. From seismograph record called the seismogram, measure time delay
between P & S wave arrival
3. Use travel time curve to determine distance to earthquake as function
of P-S time delay
Now we know distance waves traveled, but we don't know the direction from
which they came.
We must repeat the activity for each of at least three (3) stations to
triangulate a point (epicenter of quake).
Plot a circle around seismograph location; radius of circle is the distance to the
quake.
Quake occurred somewhere along that circle.
Do the same thing for at least 3 seismograph stations; circles intersect at
epicenter. Thus, point is triangulated and epicenter is located.
81. How is an Earthquake’s Epicenter
Located?
Time-distance graph
showing the average
travel times for P- and S-
waves. The farther away a
seismograph is from the
focus of an earthquake,
the longer the interval
between the arrivals of
the P- and S- waves
83. How is an Earthquake’s
Epicenter Located?
• Three seismograph stations
are needed to locate the
epicenter of an earthquake
• A circle where the radius
equals the distance to the
epicenter is drawn
• The intersection of the
circles locates the
epicenter
84. Locating an Earthquake Epicenter
• Triangulate means to use three positions to
determine an exact location.
85. What is Triangulation?
• Triangulation identifies the epicenter of an
earthquake. The location of an earthquake’s
epicenter is found by plotting circles on a map
from the records of three seismograph stations and
finding the point where the three circles intersect.
Triangulation is the process of determining the
location of a point by measuring angles to it from
known points at either end of a fixed baseline,
rather than measuring distances to the point
directly.
90. How do scientists calculate how far a location is
from the epicenter of an earthquake?
• Scientists calculate the difference
between arrival times of the P waves and
S waves
• The further away an earthquake is, the
greater the time between the arrival of
the P waves and the S waves
91. Earthquakes are measured using the Richter
Scale. The strongest earthquake ever
measured was a 9.5 on the Richter Scale. This
is a measurement of the amount of energy
released from the earthquake.
92. Measuring Earthquakes
8.2 Measuring Earthquakes
Historically, scientists have used two
different types of measurements to
describe the size of an earthquake
—intensity and magnitude.
Richter Scale
• The _Richter Scale expresses the magnitude of
an Earthquake and measures the energy released.
The scale goes from 1 to 10 .
• Based on the amplitude of the largest seismic
wave
93. How are the Size and Strength of an Earthquake
Measured?
• Magnitude
– Richter scale
measures total amount
of energy released by
an earthquake;
independent of
intensity
– Amplitude of the
largest wave produced
by an event is
corrected for distance
and assigned a value
on an open-ended
logarithmic scale
94. Determining the magnitude of an earthquake
Magnitude -- measure of energy released during earthquake.
There are several different ways to measure magnitude.
Most common magnitude measure is Richter Scale, named for
the renowned seismologist, Charles Richter.
Richter Magnitude
• Measure amplitude of largest S wave on seismograph record.
• Take into account distance between seismograph &
epicenter.
Intensity
• Intensity refers to the amount of damage done in an
earthquake
95. How are the Size and Strength of an Earthquake
Measured?
• Modified Mercalli Intensity Map
– 1994 Northridge, CA earthquake,
magnitude 6.7
• Intensity
– subjective measure
of the kind of
damage done and
people’s reactions
to it
