Earthquakes Tresha Yarberry University of Phoenix Earthquakes Everyone wonders how earthquakes happen. Although, scientists have no way of predicting earthquakes, there are ways to find out how and what causes them. People can be prepared if an earthquakes happens. There are three different types of plate margins. The first one is divergent margin, also called rifting or spreading centers. This occurs where two plates are moving apart. They can occur either in

where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. It has 452 volcanoes and is home to over 75% of the world's active and dormant volcanoes. It is sometimes called the circum-Pacific belt or the circum-Pacific seismic belt. About 90% of the world's earthquakes and 81% of the world's

design that could provide assurance to the people at times of natural calamity especially earthquake. Seismic engineers have tried many ways like having multi-layered stone infrastructures that introduced stiffness and rigidity that could resist frail earthquake movements, but then having those strongly built firm stone constructions would not be enough since it cannot withhold forceful and high level of magnitude and intensity of this catastrophic event. Seismic base isolation refers to the systematic

Although natural disasters can really only be classed a disaster if it affects humans as otherwise its impact would not necessarily be relevant so in effect all natural disasters are in effect human disasters. Seismic events, otherwise known as earthquakes, are a sudden violent shaking of the ground typically causing, as a result of the movement of tectonic plates in the earth’s crust or volcanic action. The result of seismic events is often destruction of buildings and infrastructure, which can claim

Earthquakes are one of Mother Nature’s most powerful forces and have plagued our lives for as long as people have inhabited the earth. These dangerous acts of the earth have been the cause of many deaths in the past century. So what can be done about these violent eruptions that take place nearly without warning? Predicting an earthquake, until now, has almost been technologically impossible. However, with recent improvements in technology and science, many lives have been saved and many more will

Pinatubo’s eruption. One of the precursors is the Luzon earthquake. This earthquake occurred 100 kilometers northeast of Mount Pinatubo, on the island of Luzon. The earthquake happened on July 16, 1990, which is almost a year prior to the volcano eruption event. The earthquake was measured at the magnitude of 7.8, the highest magnitude which was recorded in 1990.This earthquake is as strong as the 1906 San Francisco earthquake(USGS 2005). This earthquake caused shaking movement of the earth’s crust beneath

2006, 6). The sudden spate of disastrous earthquakes in the Americas cause concerns. Within a span of 45 days, two earthquakes hit Haiti and Chile. An earthquake, measuring 7.5 on the Richter scale, rocked Haiti on January 12, 2010, knocking down buildings and power lines and killing over 200,000 people. While the earthquake that devastated Chile, measuring 8.8 on the Richter scale on February 27 was 500 times more powerful; yet the death toll is magnitudes lower. There is the dominant approach
