Earths Major Earthquakes are caused by faulting of rock in earth's crust.Hope this helps
No single change occurs before all earthquakes.
before shokes
Big aftershocks.
The list of earthquakes by year (1990-Present) or by country can be found at the USGS Earthquake Hazards website. In 2010 there was one earthquake magnitude 8 or greater, which was in Chile (M 8.8). The USGS provides a list of significant earthquakes for 2010 as well as a worldwide map of earthquakes for 2010 and previous years. See link below.

Spills and fires are the major hazards associated with most workplace storage facilities.
Flooding, earthquakes, volcanic action.
There are five major hazards. They include: Earthquakes, volcanoes, land slides, floods ,and wildfires! Glad I could answer your question. If you have anymore I'd be happy to answer! :O
Types of accident hazards associated with the workplace include biological hazards, chemical hazards, ergonomic hazards, and physical hazards. Common physical hazards include unguarded machinery, loud noise, and spills.
Two major hazards associated with conventional explosives are accidental detonation, which can result from mishandling or improper storage, and the release of toxic gases and particles upon explosion, posing risks to the surrounding environment and human health.
California is most commonly associated with earthquakes in the lower 48 US states. California sits along the San Andreas Fault, a major tectonic boundary that is known for producing large earthquakes. Washington also experiences earthquakes, but they are less frequent and severe compared to California.
The two major hazards associated with conventional explosives are explosion and fragmentation. Explosion occurs when the explosive material is detonated, releasing a large amount of energy in a short period of time. Fragmentation refers to the flying debris and shrapnel that can cause injury or damage when an explosive device detonates.
The most common type of wave associated with major earthquakes is the seismic waves known as body waves. These waves travel through the Earth's interior and include P-waves (primary waves) and S-waves (secondary waves). They are responsible for the initial shaking felt during an earthquake.
California is associated with the most earthquakes in the United States due to its location along the San Andreas Fault, a major tectonic plate boundary. These earthquakes vary in size and frequency, with some causing significant damage and loss of life.
blast or shockwave fragmentation
earthquakes that immediately follow a major earthquake are called "aftershocks" as to small earthquakes before large earthquakes are called "foreshocks".
