by a 9.0 earthquake that also created a 30 foot tsunami wave. This earthquake killed 15,000 people and injured more than 6,000. It is said that every 250 years on the Cascadia fault, an earthquake larger than the one that hit Japan, erupts. Scientists have determined that the Cascadia fault hasn’t erupted in 300 years. This means that the West coast is 50 years overdue for an earthquake that is powerful enough to destroy every bit of civilization. The probability of the Cascadia earthquake erupting

Natalie Murillo:”Tsunamis and Coastal Homes” Research Room: 236 At the bottom of the ocean there seems to be a crack on the floor and causes an earthquake. What happens after that? Well the thing that happens after there is a crack at the bottom of the ocean that causes an earthquake is something called a tsunami. A tsunami is when a series of waves that are made in big bodies of water like a lake and river or the ocean. Tsunamis can make a lot of damage to coastlines

Foundations are the core item of a house. Earthquakes test the stability of a house. With just those few seconds of an earthquake, it could affect someone’s life immediately. The question is does the layer between soil and a house foundation affect the house’s structure during an earthquake? The hypothesis is if the layer between soil and a cement foundation of a house, then a t-shirt will allow a foundation to move less. The different layer types is the independent variable, while the dependent

wondered what causes things to happen? Ask the ancient greeks and they will tell you about the hundreds of gods that control our world. Ancient greeks believed that there are gods for everything in the world. Take Poseidon for example, the god of sea, earthquakes, and storms. Poseidon is the god that causes storms, waves, and even hurricanes. Let's look at some family, history, physical appearance, celebrations, and some amazing facts about Poseidon. Poseidon had a huge and interesting family. Poseidon's

the States of Washington and California. Abstract When a large magnitude earthquake strikes, roads might buckle, dams sometimes fail, and buildings can collapse. As more earthquakes occur, building regulations have been altered to ensure that buildings experience minimal damage. The Trans-Alaskan Pipeline System (TAPS), which transports oil from Prudhoe Bay to the Gulf of Alaska, had engineering in place so when the earthquake struck the Denali fault in Alaska in 2002, the pipeline didn’t leak any

Introduction Large magnitude earthquakes occur on plate boundaries and they can produce hazards such as movement along faults, landslides, and tsunamis if the earthquake occurs close to a large enough body of water. In North America, the western coast is an active margin, meaning that it is home to earthquakes and volcanoes, a physical manifestation of the plate activity occuring. On November 3rd, 2002, in South-Central Alaska, a 7.9 magnitude earthquake ruptured along three faults; the Susinta Glacier

Earthquakes are an unfortunate consequence of, well, living on earth. While other hazards such as volcanos, tornados, floods, and wild fires all have clear visual indications that allow for us humans to get away from them, earthquakes are much more insidious than the aforementioned disasters because they have no such indicator and the damage they inflict is near instantaneous. Luckily for us humans, seismologists have spent a good portion of the 20th century finding out why earthquakes occur, how

impacts on and in the earth around it would it still sound like an engineering feat? Say your family lives near a drill field. The chemicals that they put in the water to help it break up the rock, seeps into the city well water. Your children are drinking this water and could possibly be getting sick from the poisonous chemicals that have contaminated the city water supply. Your family could possibly even be caught in a minor earthquake because of the amount of stress that the procedure puts on the

Are Earthquake Disasters Caused by Human? Summary The intent of this paper is to prove that that the damages that are usually associated with earthquakes are actually created by a deficiency in the construction methods used around the world. First, the student will talk about the types of construction failures that contribute to damages in areas where earthquakes hit. The construction flaws include building on foundations that are prone to liquefaction and amplification of the foundation’s
