Some scientists discovered the historical and scientific evidence for a megathrust earthquake that generated a tsunami along the Cascadian subduction zone in 1700. A few geologists used radiocarbon dating and found that at least 900 kilometers (560 miles) along the fault ruptured between 1960 and 1720 (National Geographic Society [NGS], 1996). In 1996, Japanese researchers showed North American colleagues a tsunami that struck Honshu Island in 1700 to geological reports at the Cascadia subduction

“Discuss the view that the impact of earthquake hazards depends primarily on human factors (40)”. I agree to some extent about the statement above and that human factors can affect the impact of an earthquake hazard. A hazard is an object or process that has the potential to cause harm. Ground shaking, ground displacement and flooding are some of the hazards that are produced during an earthquake. In relation to the question above the type and severity of the impact can be affected by physical

and near a major earthquake fault I have pondered and wondered why our plants shake and why our planet only shakes in specific elements of the United States. While exploring for the details to finish my report, I was also able to find out the solutions to my own individual queries. This report will reply these inquiries: How does our planet shift and when, what actives cause the Earth to shake, how are earthquakes calculated and what are the two kinds of body waves and earthquake generates.

distribution of earthquakes across the continental United States? The west coast of the US consists of the highest levels of risk by a wide margin, particularly in the south-west (on the pacific tectonic plate fault line). Central Eastern regions bear areas of moderate risk. Northern and South/south-easterly regions bear no significant risk. 2) Locate your home on this map and make a note of the relative risk to you by indicating the color where you live. The USGS also reports on earthquakes around the

examples, suggest why the impacts of tectonic hazards vary from place to place Tectonic hazards are natural events occurring due to movements or deformations of the earth’s crust with the potential to cause damage to lives and properties. E.g. earthquake and volcanic activities. The impact caused by tectonic hazards on lives and properties are mainly determined by physical factors, vulnerability factors and affected region’s capacity to cope. These factors are parts of the risk equation, which is

Earthquake The strongest earthquake in 25 years in Northern California's Bay Area struck early Sunday, injuring dozens of people, damaging historic buildings in downtown Napa and turning fireplaces into rubble. The 6.0-magnitude quake struck just six miles southwest of Napa, California's famed wine country. Nearly 160 were treated for minor injuries at the emergency room at Queen of the Valley Hospital, though hospital CEO Walt Mickens could not confirm that all of those patients were injured

statement: The extent to which earthquakes present a hazard depends on where they are experienced. (40 marks) A Hazard is best defined as a situation that’s ‘a potential source of harm or adverse health effect on a person or persons’. An earthquake is a tectonic event which can be a huge hazard to people- particularly effecting areas of the earth around convergent, divergent and transform plate boundaries: in both MEDC’s and LEDC’s with equally force. Hazards earthquakes cause can be divided into
