In its most general sense, the word earthquake is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear tests. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the epicenter.
Earthquake environmental effects are divided into two main types: Coseismic surface faulting induced by the 1915 Fucino, Central Italy, earthquake. Primary effects: which are the surface expression of the seismogenic source (e.g., surface faulting), normally observed for crustal earthquakes above a given magnitude threshold (typically M w =5.5 ...
Movement of tectonic plates against each other sends seismic waves rippling across earth’s surface
More than 2,000 people died and thousands more were injured following a massive earthquake that hit Gaziantep, a town in southeastern Turkey near the Syrian border early Monday morning. Additional ...
The Aleutian Trench, of the southern coast of Alaska and the Aleutian Islands, where the North American plate overrides the Pacific plate, has generated many major earthquakes throughout history, several of which generated Pacific-wide tsunamis, [22] including the 1964 Alaska earthquake; at magnitude 9.1–9.2, it remains the largest recorded ...
Taiwan and its surrounding waters have registered about 2,000 earthquakes with a magnitude of 4.0 or greater since 1980, and more than 100 earthquakes with a magnitude above 5.5, according to the ...
Therefore, they create a surge in the website traffic which can indicate that an earthquake just occurred, even before receiving data provided by national seismological institutes. By identifying the geographical origin of the website's visitors, the area where the earthquake was felt is mapped within a couple of minutes of its occurrence.
