Tectonic earthquakes are a particular kind of earthquake that are associated with the earth's crustal deformation; when these earthquakes occur beneath the sea, the water above the deformed area is displaced from its equilibrium position. Most of the world’s earthquakes, tsunamis, landslides, and volcanic eruptions are caused by the continuous motions of the many tectonic plates that make up the Earth’s outer shell. "By studying these micron-scale measurements it is possible to better understand large-scale processes. Boron fingerprints revealed that the water-rich mineral serpentine, contained in the sinking plate, is a dominant supplier of water to the central region of the Lesser Antilles arc. Colin Macpherson, Durham University, said.Prof. The same process can trigger earthquakes and may affect key properties such as their magnitude and whether they trigger tsunamis or not.” For the study, scientists collected data over two marine scientific cruises on the RRS James Cook, temporary deployments of seismic stations that recorded earthquakes beneath the islands, geological fieldwork, chemical and mineral analyses of … This magma is buoyant and moves upwards, ultimately leading to eruptions in the overlying volcanic arc.

"The wettest parts of the downgoing plate are where there are major cracks (or fracture zones). "The wettest parts of the downgoing plate are where there are major cracks (or fracture zones).
