soil is reduced by earthquake shaking or other rapid loading. Liquefaction and related phenomena have been responsible for tremendous amounts of damage in historical earthquakes around the world. Liquefaction occurs in saturated soils, that is, soils in which the space between individual particles is completely filled with water. This water exerts a pressure on the soil particles that influences how tightly the particles themselves are pressed together. Prior to an earthquake, the water pressure

this excerpt came from Voltaire’s Candide a French satire published during Europe’s Age of Enlightenment. This gives a chilling view of Lisbon on All Saint’s Day (November first) in 1755. What had occurred is a 200 km offshore 8.5-9.0 magnitude earthquake that resulted in a large-scale tsunami and rampaging fires, effectively killing thousands of people. This is one of the deadliest tsunamis recorded in history, but how do tsunamis function and what do we know about their inner workings. Tsunamis

Earthquakes are an example of seismic activity created by plate boundaries. They can be caused by the subduction of oceanic crust which is densest at 2.9 g/cm3 under continental crust which weighs 2.7g/m3 at destructive plate boundaries. Earthquakes can also occur along conservative plate boundaries such as that shared by the Pacific and North American plates which move at 5-9 cm/year and 2-3 cm/year respectively causing the 1994 Los Angeles earthquake along the San Andreas fault alongside which
