Studies of liquefaction features left by prehistoric earthquakes, called paleoliquefaction or paleoseismology, can reveal information about earthquakes that occurred before records were kept or accurate measurements could be taken. [21] Soil liquefaction induced by earthquake shaking is a major contributor to urban seismic risk.
Coseismic liquefaction induced by one of the 2012 Emilia, Northern Italy, earthquakes. Secondary effects: mostly this is the intensity of the ground shaking (e.g., landslides, liquefaction, etc.). The importance of a tool to measure earthquake Intensity was already outlined early in the 1990s. [2]
Paleoliquefaction is any liquefaction features attributed to seismic events occurring before measurements or written records were kept of earthquakes. [1] The study of these features can reveal a great deal about the seismicity of regions where large earthquakes happen infrequently. This is a subset of the broader field of paleoseismology.
About 55 earthquakes a day – 20,000 a year – are recorded by the National Earthquake Information Center. A quick guide to how they are measured. Earthquakes happen all the time, you just can't ...
The term ground failure is a general reference to landslides, liquefaction, lateral spreads, and any other consequence of shaking that affects the stability of the ground. This usually takes place as an after-effect of an earthquake, and is one of the major causes of destruction after an earthquake. Ground failures tend to happen almost every ...

Strong earthquakes can lead to damage, tsunami warnings and more. People can also be injured or killed by damage caused by a quake. Here's what to know about earthquake activity and what causes ...
As an example of the latter, a "major commercial application of liquefaction is the liquefaction of air to allow separation of the constituents, such as oxygen, nitrogen, and the noble gases." [4] Another is the conversion of solid coal into a liquid form usable as a substitute for liquid fuels. [5]
