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.Know More
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 in Earthquakes
According to the U.S. Geological Society, the area in the Earth's crust where an earthquake forms is called the hypocenter. Unpredictable in nature, earthquakes form when energy from the crust is released, causing vibrations on the surface of the earth. The magnitude of earthquakes can vary exponentially, and the stronger the magnitude, the more devastating the effects, especially on areas that are near the epicenter.Full Answer >
The U.S. Geological Survey reports that, as of 2014, Alaska accounts for about half of all earthquakes registered in the United States. The USGS also indicates that many smaller magnitude earthquakes go unreported in the state. California has the second-most reported earthquakes among U.S. states.Full Answer >
Scientists can make predictions about earthquake probability, but there is no reliable way to foresee any given earthquake. Some people have claimed that they can predict earthquakes, but their claims do not withstand scientific scrutiny.Full Answer >
Earthquakes are usually triggered when rock located beneath the ground, on top of fault lines, breaks and suddenly releases a significant amount of energy. The immediate and rapid release of energy caused by earthquakes generates seismic waves, which cause shaking motions that start below the Earth’s surface and spread across large distances.Full Answer >
