Intraplate earthquake - Wikipedia
An intraplate earthquake occurs in the interior of a tectonic plate, in contrast to an interplate earthquake on the boundary of a tectonic plate. [1] [2] They are relatively rare compared to the more familiar interplate earthquakes.
Understanding intraplate earthquakes - Geodynamics
2020年7月8日 · One of the basic tenets of plate tectonics states that deformation occurs along plate boundaries while plate interiors remain almost undeformed. Intraplate earthquakes defy this principle and hence are quite enigmatic.

2020年2月26日 · The widespread intraplate volcanism in northeast China and the unusual ‘petit-spot’ volcanoes offshore Japan could have resulted from the interaction of the subducting Pacific slab with a ...
Intraplate volcanism - Wikipedia
Intraplate volcanism is volcanism that takes place away from the margins of tectonic plates. Most volcanic activity takes place on plate margins, and there is broad consensus among geologists that this activity is explained well by the theory of plate tectonics .

近年来，有一类特殊的火山逐渐引起了地球科学家的重视：一种既不属于地幔柱成因，又远离板块边界（>1000 km），如长白山火山；还有一种叫做“petit-spot”，它具有EM1的地球化学特征（图1），但不属于洋岛玄武岩，如太平洋底新发现的小火山。 这两种火山分别出现在日本俯冲带的前方和后方，它们的成因无法用经典的板块构造理论解释，还存在巨大的争议（Sun et al.,2017；Zhang et al.,2018；Chen and Faccenda,2019；Fan and Chen,2019；Lai et …
Intraplate Earthquakes
2024年11月18日 · Intraplate. Instead of occurring on plate boundaries, intraplate earthquakes occur within plates. They are caused by stress from plate motion, and usually happen along older faults or rifts that have been weakened. Past examples are Virginia in …
Seismicity, Intraplate - SpringerLink
2021年1月1日 · Intraplate seismicity is a catchall phrase that encompasses a wide variety of seismogenic phenomena; essentially all earthquakes that do not occur on plate bounding faults. Locales hosting intraplate earthquakes range from broad deformation zones that surround some plate boundaries to areas that lie within the cores of continents.

2021年1月1日 · However, large devastating continental earthquakes do also occur in the plate interior far away from plate boundaries, which are known as intraplate earthquakes. Mechanism of Intraplate Earthquakes
5.15: Intraplate Activity - Geosciences LibreTexts
A small amount of geologic activity, known as intraplate activity, does not take place at plate boundaries but within a plate instead. Mantle plumes are pipes of hot rock that rise through the mantle.
6.11: Intraplate Earthquakes - K12 LibreTexts
2021年1月11日 · Intraplate Earthquakes. About 5% of earthquakes take place within a plate, away from plate boundaries. These intraplate earthquakes are caused by stresses within a plate. Since plates move over a spherical surface, zones of weakness are created. Intraplate earthquakes happen along these zones of weakness.
