The study explained that Spain is unusually vulnerable to deep and rare earthquakes, indicating that this inverted tectonic plate may have something to do with it. Geologists Daoyuan Sun from the Chinese University of Science and Technology and Megan Miller from the Australian National University explained: “Since 1954 There were 5 large, closely focused earthquakes close together at a depth greater than 600 kilometers beneath the Spanish city of Granada. Earthquakes that occur at these depths are usually followed by large aftershocks, but when Sun and Miller examined seismic data from the 2010 Spain earthquake, there were no tremors. A rebound that can be seen. According to the study, when tectonic plates push towards each other, they are often displaced so that one slides under the other in a process called subduction, and sometimes these collisions lead to the destruction of the sunken part of the plate, which leads to the crust being raised to form mountains. The fates of the two plates are intertwined as one. The submerged slab forms hydrated magnesium silicate in its upper layers when it is exposed to ocean water. As the slab sinks, these silicates dry out and become more brittle, becoming more vulnerable to earthquakes and slowing seismic waves in a way that seismologists can detect. Seismic waves continued during the 2010 Granada earthquake. , for an unusually long period and had an additional late phase of activity, which can be explained by seismic waves moving more slowly at the bottom of the borane slab rather than the top. “A large amount of water was transported into the mantle transition zone,” Sun explained. “This indicates the presence of a relatively cold slab.” The new study goes further by concluding that it overturned completely, plunging the silicate side down in a way that could explain the strange complexity of the region’s tectonic structures and occasional earthquakes more than 600 kilometers deep, according to the journal. "Science Alert", the scientists concluded by saying: "This confirms that the slab beneath Betic in southern Spain is a submerged oceanic lithosphere."
