    The Epicenter, location on the earths surface directly above focus, of the '64 earthquake is located in the northern part of the Prince William Sound; specifically 61.04º N- 147.73º W, approximately 75 miles east of Anchorage. The focus, or depth of the earthquake, is estimated at 25 miles below the epicenter. In general, the lower the earthquake occurs below the surface of the earth, the weaker it is; 25 miles is relatively close to the surface compared to most earthquakes that occur in…

    The largest earthquake recorded in the 20th century is the 1960 Valdivia earthquake, also known as the Great Chilean earthquake which occurred on May 22, 1960 and hit approximately 100 miles off the coast of Chile, which is parallel to the city of Valdivia. With a rate of 9.5 on the moment magnitude scale, this earthquake occurred in the afternoon and lasted approximately 2 minutes (brit). After just thirty minutes of the major earthquake, a foreshock shook the area near the towns of Valdivia and Peurta Montt (kids). The four foreshocks that followed had a magnitude of greater than 7.0. The largest earthquake had a magnitude of 7.9 and caused a large amount of damage to the Concepcion area. The devastating earthquake triggered a tsunami just off the coast of central Chile, which affected the entire Pacific Basin (usgs). After Chile, the tsunami traveled hundreds of miles and caused destruction all around the Pacific. The places that experienced the most impact was Hawaii and Japan (2010). The earthquake set off waves which bounced back and forth across the Pacific Ocean for a week (history). The Great Chilean earthquake along with the large tsunamis, has caused substantial damage to the country, it resulted to loss of life and homes, and presented long-term effects. Although the massive destruction had an overall negative…

    The results of these earthquakes was devastating. Trees were up rooted and looked to be tossed around like toothpicks. There was wide spread damage extending from St. Louis to all the way to Pennsylvania where supposedly the Liberty bell rang from the strong quakes.(Nuttli) Thirty miles south, in the river town of what is today Caruthersville, Missouri, all twenty houses were destroyed, and the surrounding land was rendered almost unrecognizable. The ground rolled in several-foot-high waves until they burst, hurling up geysers of water, sand, and a charcoal-like substance. Giant fissures swallowed buildings, along with anyone inside.…

    Economic cost was high with losses estimated at $40 billion. The earthquake severely tested building codes, earthquake-resistant construction and emergency preparation and response procedures. The experience confirmed many of the lessons learned from past earthquakes, exposed weaknesses in the society’s generally resilient fabric, and produced many surprises about the levels and consequences of strong ground shaking. Near the epicenter in the San Fernando Valley, well-engineered buildings withstood violent shaking without structural damage. However, numerous structural failures throughout the region were evidence of significant…

    This is caused by shallow-focus underwater earthquake; volcanic eruption and large land slide into the sea. The displacement of the water becomes the giant sea wave and they normally have a long wavelength over 100m and low wave height when they are still in the open ocean. When it approaches shallower water near the shoreline the speed and the height increases and it can reach 700km/h. tsunami is one of the most deadly seismic hazards can cause significant damage to buildings and infrastructure. On March 11, 2011, a magnitude-9 earthquake shook northeastern Japan, unleashing a savage tsunami.

    The amount of damage caused by an Earthquake does not solely depend on the magnitude of the Earthquake. Factors such as population, geographic location, soil type, and the type of building material commonly used for construction in a region determine the extent of damage caused. If an Earthquake strikes a densely populated region, then life loss and property damage will be high. If an Earthquake of a similar or even higher magnitude strikes a region with a relatively low population, then life loss and property damage will be lower. The 6.4 Richter scale Earthquake (1993) in the State of Maharashtra, India and the 8.3 Richter scale Earthquake (2006) in Kuril Islands, Japan are examples that come to mind. With stone houses and a population of over 2 million, the Earthquake in Latur left nearly 8,000 people dead and brought as many as 30,000 houses to the ground. In contrast, Kuril Islands, with a population of just 17,000 and better disaster preparedness mechanisms, was able to get away with no loss of human life ,despite the fact that the Earthquake was much higher in magnitude when compared to that of Latur.…

The fires had burned for four days; some say it was caused by broken gas lines. Since the water remains had broken, trying to put the fires out was almost impossible to do, Because of it, five hundred city blocks were destroyed. But the damages had been estimated to about four-hundred million dollars just to be fixed. It would be actually 8.2…
