EARTHQUAKE An earthquake (also known as a tremor‚ temblor or seismic activity) is the result of a sudden release of energy in the earth’s crust that creates SEISMIC WAVES. Earthquakes are measured with a seismometer; a device which also records is known as a seismograph. SEISMIC DEFORMATION When an earthquake fault ruptures‚ it causes two types of deformation: static; and dynamic. Static deformation is the permanent displacement of the ground due to the event. The earthquake cycle progresses

Dear the Society for Earthquake Enthusiasts; I feel as a member of the Society for Earthquake Enthusiasts‚ I need to express my opinion on your ideas to move our headquarters to San Francisco. While I am a lover of California and appreciate California from afar‚ I feel as though we should rethink relocating to California. I feel as though this is the best choice to make due to the fact that the earthquake of 1906 was just only a preview of what the San Andreas Fault can do to San Francisco. Due

tranquil southeast region of Washington State located in the Cascade Mountains‚ began to tremble with earthquake activity lasting until the afternoon of the 26th of March. This was the first of many warnings to geographers and local authorities of the impending dangerous eruption coming from the normally silent Mount Saint Helens. The richter magnitude range was 2.6-4.2. There were 142 recorded earthquakes over 2.4 in the 24 hours between March 26 and 27th. The volcano began to spew ash at 1236. (Girty

The population in Japan is considered quite high‚ about 127‚817‚277 people in this small country. Therefore‚ this has made Japan became one of the most tightly populated country in the world‚ ranking the 36th placing. Earthquakes are very common in Japan. In fact‚ Japan had suffered more earthquakes compared to other. Therefore‚ engineers have put in a lot of

Loma Prieta Earthquake Story Teller By: Kavita Butani There is a lot that happens around the world we cannot control. We cannot stop earthquakes‚ we cannot prevent droughts‚ and we cannot prevent conflict. Earthquakes and the damages they bring have affected the lives of many people around the world forever. As our community grows so does the danger caused by these quakes also increases by mass. Earthquakes can affect our lives in many ways; this type of natural disaster can upset everything from

GUJARAT EARTHQUAKE MORE DESTRUCTIVE THAN THE SAN FRANCISCO EARTHQUAKE? In 1989 an earthquake hit San Francisco‚ on the west coast of USA‚ killing around 63 people. Twelve years later an earthquake hit Gujarat‚ in India. This time it killed approximately 20‚000 people. In this report I will be comparing the two earthquakes‚ giving reasons why the Gujarat earthquake was so much more destructive than the one in San Francisco. An earthquake is a movement or tremor in the earth’s crust. Earthquakes happen

Investigations of past and recent earthquake damage have illustrated that the building structures are vulnerable to severe damage and/or collapse during moderate to strong ground motion. Among the possible structural damages‚ seismic induced pounding has been commonly observed in several earthquakes. A parametric study on buildings pounding response as well as proper seismic hazard mitigation practice for adjacent buildings is carried out. Three categories of recorded earthquake excitation are used for input

deadliest earthquake in history killed 840‚000 people‚ But many other earthquake have caused the dead of more than 100‚000 people and isn’t unusual‚ even in modern times‚ for an earthquake death toll to reach 20‚000 to 20‚000 people with hundreds of thousands left homeless. There are four factors that affect the casualty rate and economic impact of earthquake: magnitude‚ location‚ quality of construction of building‚ and timing. Magnitude The magnitude‚ or strength‚ of an earthquake is measured
