1. The largest earthquake in recorded history was the 1960 Chile earthquake, measuring 9.5 magnitude. It caused over 2,000 deaths and $550 million in damage. 2. The second largest was the 1964 Alaska earthquake, measuring 9.2 magnitude. It was the largest recorded in the United States. 3. On average, the San Andreas Fault Zone moves 56 mm per year, around the same rate as fingernails grow. In around 15 million years, Los Angeles and San Francisco are projected to be adjacent to each other due to this movement.

Earthquake inquiry
An earthquake occurred near Christchurch, New Zealand at 12:51pm with a magnitude of 6.3 and depth of 5km, causing 65 confirmed deaths. Students conducted an experiment with sandpaper and wooden plates to simulate how tectonic plates rubbing together can cause quakes.
Lisa's Christchurch earthquake
On February 22, 2011 at 12:51pm, a magnitude 6.3 earthquake struck Christchurch, New Zealand. The earthquake was centered 10km southeast of the city at a depth of 5km. It was felt throughout the South Island and lower North Island. In the aftermath, groups of volunteers from across New Zealand helped with cleanup efforts, including a group of 800 farmers called the Farmy Army and 10,000 university students and others in the UCSA Student Volunteer Army.
Taylor Bonner "The Great Alaska Earthquake"
The Great Alaskan Earthquake of 1964 occurred in Prince William Sound, Alaska on March 27th at 5:36pm. It lasted approximately 4 minutes and registered a magnitude of 9.2, making it the second largest earthquake ever recorded. Over 130 people were killed, many by the tsunamis that followed. The earthquake and tsunamis caused widespread damage estimated at 300-400 million dollars and helped reveal the theory of plate tectonics to explain earthquakes. Thousands of aftershocks continued over the following year.
New zealand and the christchurch earthquake 2
The document provides information about the 2010-2011 Christchurch earthquakes in New Zealand. It details that the first earthquake on September 4, 2010 was magnitude 7.1 and centered near Darfield. The more destructive earthquake was on February 22, 2011 with a magnitude of 6.3 centered 10km southeast of Christchurch. This earthquake caused widespread damage in Christchurch and 181 deaths. Analysis showed the earthquake was caused by movement along a previously unknown fault running beneath the southern edge of Christchurch.

The volcanic eruption of Krakatoa in 1883 was the most powerful explosion in recorded history, killing over 36,000 people and destroying 160 villages with an eruption ten thousand times more powerful than the atomic bomb. Earthquakes occur when tectonic plates rub against each other, capable of destroying cities and moving mountains, such as the 1906 San Francisco earthquake that toppled buildings and sparked fires that burned most of the city. The 2011 Christchurch earthquake of magnitude 6.3 caused many buildings to collapse, killing between 175 and 200 people and requiring the rebuilding of the central city.

A tsunami is a huge wave caused by an earthquake on the ocean floor. The 2011 Japanese tsunami hit Fukushima and badly damaged a nuclear power plant, drowning at least 20,000 people and leaving 20,000 missing. In 1792, a volcanic eruption in Japan caused a tsunami that killed 15,000 people, and in 1958 Alaska experienced a 524m tsunami from an earthquake that killed 5 people.
Alaska Earthquakes & Tsunami Presentation
- A series of great earthquakes between 1938 and 1965 ruptured almost the entire Alaska subduction zone. The average recurrence time for magnitude 9 earthquakes in this region is 700-900 years.
- During the 1964 Alaska earthquake, areas in the uplift zone were raised up to 6 meters while areas in the subsidence zone dropped over 2 meters. This vertical displacement contributed to tsunami generation and inundation.
- Tsunamis deposit distinct sediment layers that can be used to date past events. Analysis of sediment layers at sites like Girdwood has revealed evidence of tsunamis occurring every 280-295 years on average in that region of Alaska.

Earthquakes[1].ppt
Earthquakes are caused by the shaking and vibration of the earth's crust. They occur around the world and can cause devastating effects such as landslides, avalanches, tsunamis, and damage to buildings and infrastructure. While some regions are more prone to earthquakes, they are difficult to predict precisely and can strike with little or no warning. Scientists study earthquake mechanisms and seismic waves to build more earthquake resistant structures, but risk can never be fully eliminated.
napsetr-earthquake
Earthquakes are caused by movements in the earth's crust that generate shaking and vibrations. They can cause significant damage depending on their magnitude and intensity. While earthquakes occur frequently around the world, some areas are more prone to them than others. Major earthquakes since 1900 include a 9.5 magnitude quake in Chile in 1960 and a 9.0 magnitude quake off the coast of Indonesia in 2004 that triggered a devastating tsunami. Scientists have gained significant understanding of where earthquakes are likely to occur but still cannot reliably predict specific future events. Structures can be designed to better withstand shaking but no building can be completely earthquake-proof.

ROUGH DRAFT
A few minutes of intense shaking, followed by a devastating tsunami, producing widespread destruction. FEMA's best-case scenario, 13,000 people will lose their lives, (Schultz, 2015). The question is not if it's going to happen, it's when. The countdown to catastrophe is on for the Pacific Northwest. We're talking about the Cascadia Subduction Zone. Throughout this paper, I will discuss the who, what, where, when, and how this overdue megaquake will strike.
The Cascadia subduction zone is a 620-mile-long crack in the earth's crust. It is in the pacific northwest where the North American tectonic plate meets the Juan de Fuca plate, (Tarbuck, Lutgens, Tasa, 2017). Tectonic plates are pieces of crust that move across the earth's surface over millions of years, (Oskin, 2015). The subduction zone is where two tectonic plates meet. One eventually bends underneath the other, which is what we see in the North Pacific. The Juan de Fuca plate is sliding under the weaker, North American plate. Eventually, the North American plate will buckle, result in a devastating earthquake, followed by massive Tsunami.
Subduction zones are found all along the edge of the Pacific in what is called, "The ring of fire." Off the coasts of Washington, Canada, Alaska, Russia, and Indonesia birthed the most devastating earthquakes, tsunamis and volcanic eruptions in history, (Oskin, 2015). The bigger the subduction zone, the higher magnitude of the earthquake. A subduction zone earthquake with a magnitude of 7.5 or greater will likely produce a tsunami. The Cascadia subduction zone is a big one. It runs 620 miles long and 62 miles wide. It has all the ingredients necessary to produce massive devastation.
So how do we know that the Pacific Northwest is in danger? Tsunamis are a direct result of an earthquake, volcanic eruption or a massive landslide. The once dubbed, "Orphan Tsunami," hit the eastern coast of Japan on January 27th, 1700, (Atwater et al., 2015). The year 1700 in the Pacific Northwest was considered prehistory, meaning there were no written records of events. Japan, on the other hand, have produced numerous ancient writings of stories that told of flooded fields, wrecked houses, fire, a shipwreck, and evacuations. The Japanese knew that tsunamis were a result of an earthquake, and because they didn't feel any shaking prior, they called the event a high tide. At the time, it wasn't known that tsunamis could occur from earthquakes that happened from faraway lands. Outsiders of Northwestern North America scarcely knew of its existence. At that time, leading European geographers left that part of the map blank. So, for this mystery, the Japanese didn't even know the Pacific Northwest existed, much less that it had produced the earthquake that generated the tsunami, (Atwater et al., 2015).

Earthquakes presentation bn
Earthquakes are caused by movements of tectonic plates underneath the Earth's surface along faults. Scientists use instruments like seismographs and magnetometers to detect and record earthquakes. While it is difficult to precisely predict earthquakes, some research has shown animals can sense them before they occur. Major earthquakes cause extensive damage by collapsing buildings and breaking gas pipes and power lines, which can lead to fires. Some of the most devastating earthquakes in recent history include those in Haiti in 2010, Chile in 2010, San Francisco in 1989, and Colombia in 1979.
Challenge yourself
The document discusses tsunamis, including their causes and most destructive historical events. It provides details on four questions: 1) Natural events that can cause tsunamis include earthquakes, landslides, volcanic eruptions and meteor strikes underwater. 2) Tsunamis are incorrectly called tidal waves or seismic sea waves, as they are more like a wall of water rather than a wave, and can be caused by underwater seismic events rather than tides or waves. 3) Most tsunamis occur in the Pacific Ring of Fire due to the many earthquake- and volcanic-prone boundaries there. 4) A chart lists some of the most destructive tsunamis by date, location, cause, deaths
Earth quake
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.
tsunami[1].ppt
The document provides information about tsunamis, including what causes them, how they behave in deep ocean versus shallow coastal waters, examples of destructive past tsunamis, and tips for preparing for tsunamis. It discusses how tsunamis are formed by earthquakes, landslides, volcanic eruptions and other events. It also explains that while tsunamis have long wavelengths and travel fast in deep ocean, they slow down and grow taller as they reach shallow coastal waters, potentially reaching over 100 feet high. Examples of destructive tsunamis discussed include those in Hawaii in 1975 and 1960, Alaska in 1964, Chile in 1960, and Peru in 1996.
Earthquakes
Earthquakes occur along plate boundaries due to the buildup and sudden release of energy from shifting tectonic plates. When plates lock, potential energy builds until released as seismic waves that propagate outward from the earthquake focus. Most earthquakes occur along oceanic and continental plate edges or along faults like normal, reverse, and transform boundaries. P and S waves are the primary seismic waves, with P waves traveling faster and S waves causing the shaking felt during quakes. Earthquake magnitude measures the energy released using the Richter scale, while intensity qualitatively describes the shaking effects on a place using the Mercalli scale.
Wow earthquake
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.
Earthquake Notes Summary
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.

1. The wildfire in Peshtigo, Wisconsin in 1871 destroyed over 1 million acres and killed an estimated 1,200 people.
2. The "Storm of the Century" blizzard in 1993 brought tornadoes, ice, and high winds across Canada, the U.S., and Cuba, causing $6 billion in damages and over 300 deaths.

Good Friday Quake
This is a PowerPoint presentation about the 1964 earthquake that hit Alaska on Good Friday, March 27th, at 5:37 pm. A 9.2 on the Moment Magnitude Scale, this was the second largest earthquake in recorded history, generated huge tsunamis, killed 131 people, and cost over 300 million dollars in property damage.
Wak disasters
Earthquakes occur along fault lines when tectonic plates collide or scrape against each other. The San Andreas Fault in California is responsible for some of the most destructive quakes in U.S. history due to the North American and Pacific plates scraping past each other there. Major quakes can cause tsunamis, massive ocean waves caused by underwater seismic activity that can devastate coastal areas.
