What causes earthquakes? Interestingly, as liquids do not propagate the energy of seismic waves, the liquefied soil acts to dampen further impacts of the earthquake. As the edges of these plates slide against each other in fault zones, friction can slow them down, leading to the buildup of pressure over long periods of time. After an earthquake.

Walk out carefully watching for anything that could fall during the aftershocks. Surviving an earthquake and reducing its health impact requires preparation, planning, and practice. The tectonic plates that make up the earth's crust are moving constantly. Earthquake safety should not be a big concern when traveling, but in the unlikely event that an earthquake does occur, it doesn't hurt to know what to do during and have a plan. The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977, and the USGS Advanced National Seismic System (ANSS) was established by Congress as a NEHRP facility. If severe shaking lasts 20 seconds or more, immediately evacuate to high ground as a tsunami might have been generated by the earthquake. When the rocks break, the earthquake occurs.
