The major dangers of earthquakes include other hazardous effects that could occur after an earthquake subsides, such as liquefaction, tsunamis, further ground tremors and landslides. By being aware of these dangers, in the event that they occur, it is possible to get to safety faster.Continue Reading
Liquefaction is the process of the ground melting down to a liquid state after an earthquake, according to the Cascadia Region Earthquake Workgroup or CREW. After liquefaction, the ground may no longer be solid, which puts buildings and other foundations at risk.
Tsunamis typically occur after an earthquake and may cause massive waves due to the reverberations of the earthquake, according to scientific resource GNS Science. If a volcano erupts, this can also cause a tsunami. During tsunamis, it is best to get as far away from the ocean as possible, as the waves are typically far larger than normal and thus can cover more ground and cause more damage.
Even after an earthquake ends, ground tremors may still persist, CREW notes. This could cause even more harm to areas already damaged by an earthquake. If ground tremors occur after the earthquake, it is best to stay in a safe place until they subside.
Naturally, with so much shaking occurring, portions of rock or ground can begin to slough off and fall, causing landslides. Rock falls may also happen, according to GNS Science. In the event of a landslide, it is best to be as far away from large rock formations or tall hills and cliffs as possible.Learn more about Earthquakes
Effects of earthquakes on the biosphere include landslides, tsunamis and liquefying of soil. Earthquakes are thought to release methane gas from oceans into the atmosphere. Extremely strong earthquakes can affect the Earth's rotation and change the shape of the planet.Full Answer >
The United States Geological Survey Earthquake Hazard Program provides a live earthquake monitoring system that monitors time, location, depth, and other valuable information on earthquakes worldwide. The website also offers several learning resources, live global maps and seismic activity archives.Full Answer >
As of 2015, there are no instruments available that can actually predict an earthquake, but instruments used to detect earthquakes include creepmeters, strainmeters, tiltmeters and pore pressure monitors. These tools are used by the United States Geological Survey in fault lines and volcanoes in the United States. Each tool has a unique and equally important role in helping seismologists determine when earthquakes occur.Full Answer >
Some of the largest earthquakes ever recorded include the Chilean earthquake of 1960, the Prince William Sound earthquake of 1964 and the earthquake in Sumatra, Indonesia, in 2004. Other large earthquakes occurred in Sendai, Japan, in 2011 and Kamchatka, Russia, in 1952. While even larger earthquakes may have occurred in the past, the technology did not yet exist for accurate measurements and records.Full Answer >
