Even at low magnitudes, earthquakes can be felt in different cities than they originate in, just like Michigan's most recent 3.2-magnitude earthquake in 2020 with an epicenter about 2 miles ...
A meteotsunami or meteorological tsunami[1] is a tsunami -like sea wave of meteorological origin. Meteotsunamis are generated when rapid changes in barometric pressure cause the displacement of a body of water. In contrast to impulse-type tsunami sources, a traveling atmospheric disturbance normally interacts with the ocean over a limited ...
Depth of focus (tectonics) In seismology, the depth of focus or focal depth is the depth at which an earthquake occurs. Earthquakes occurring at a depth of less than 70 km (43 mi) are classified as shallow-focus earthquakes, while those with a focal depth between 70 km (43 mi) and 300 km (190 mi) are commonly termed mid-focus or intermediate ...
A seismic shadow zone is an area of the Earth 's surface where seismographs cannot detect direct P waves and/or S waves from an earthquake. This is due to liquid layers or structures within the Earth's surface. The most recognized shadow zone is due to the core-mantle boundary where P waves are refracted and S waves are stopped at the liquid ...
It's not uncommon for an earthquake to have a ripple effect creating giant waves after water has been displaced — commonly known as a tsunami. ... 800-290-4726 more ways to reach us.
A 2.9 magnitude earthquake took place in Lake Michigan off the shore of Sturgeon Bay around 9:00 am Friday. Lake Michigan had a 2.9 magnitude earthquake Friday morning, a rare occurrence Skip to ...
Cryoseism. A cryoseism, ice quake or frost quake, [1][2][3][4] is a seismic event caused by a sudden cracking action in frozen soil or rock saturated with water or ice, [5] or by stresses generated at frozen lakes. [6] As water drains into the ground, it may eventually freeze and expand under colder temperatures, putting stress on its surroundings.
The term seismic sea wave is also used to refer to the phenomenon because the waves most often are generated by seismic activity such as earthquakes. [19] Prior to the rise of the use of the term tsunami in English, scientists generally encouraged the use of the term seismic sea wave rather than tidal wave.
