Magmatic and tectonic systems interact at timescales of seconds to years, leading to the triggering of volcanic eruptions by large magnitude earthquakes, and earthquakes by magmatic activity.LaFeminaPerfitt, M.R. y Davidson, J.P. (2000). Plate tectonics and volcanism. En: Encyclopedia of ...
Volcanism at divergent and convergent plate margins (USGS) A connection between earthquakes and volcanic activity has probably been suspected since the earliest history of mankind. But it is the theory of Plate Tectonics to allow explaining the deeper relationship between the two phenomena and explainin...
THE most important feature of the present tectonic situation off the west coast of Canada is the ridge–trench–fault type triple junction between the Juan de Fuca, Pacific and American lithospheric plates near the continental margin, at approximately 51°N (Fig. 1). The half spreading rate for...
Plate tectonics describes the movement of the Earth's lithosphere, consisting of its rigid crust and upper mantle. This is the driving force behind continental drift, which saw a single vast supercontinent called Pangaea break up roughly 250 million years ago, fragmenting to form the familiar mode...
Linking plate tectonics and volcanism to deep earth dynamics – A tribute to Trond H. Torsvikdoi:10.1016/j.tecto.2019.03.002Gaina, CarmenNiocaill, Conall MacConrad, Clinton P.Steinberger, BernhardSvensen, Henrik H.Elsevier ScienceTectonophysics...
plate tectonics n. 1.(used with a sing. verb)A theory that explains the global distribution of geological phenomena such as seismicity, volcanism, continental drift, and mountain building in terms of the formation, destruction, movement, and interaction of the earth's lithospheric plates. ...
Both kinds of plate boundary are associated with fault systems, earthquakes and volcanism,but the kinds of geologic activity observed at the two boundaries are quite different. The idea of sea-floor spreading actually preceded the theory of plate tectonics. In its original version, in the early...

"You still have volcanism on stagnant lid planets, but it's much shorter lived than on planets with plate tectonics because there isn't as much cycling," said Smye. "Volcanoes result in a succession of lava flows, which are buried like layers of a cake over time. Rocks and sediment hea...
