Research provides new insights: the seismic source depth affects potential tsunami scale

According to CNBETA: According to a new study, the earthquake-like earthquake can cause a tsunami with a size. This is often observed, but the phenomenon that is not fully understood hinders reliable warnings to local tsunamins. Research on the leadership of Scientists from Moza, Hawaii, providing new insights, feature-magnificent, two construction sections, the depth of constructing plates, and the hardness of the associated sector - the potential of the tsunami produced The scale is linked.

Previous researchers have identified a special event called tsunami earthquakes, they produce huge tsunami with uncomfortable proportion thereof. Kwok Fai Cheung, Ocean and Earth Science and Technology (SOEST), University of Monas, Hawaii, Kwok Fai Cheung, THORNE LAY and CROS, California, found direct explanations for this problem. Their discoveries were recently published in "Nature - Earth Science".

The team uses a computer model that will generate a physical process of the earthquake and tsunami combined with a wide range of observations of real world events, including those that are classified as tsunami earthquakes. The model results show that for a given seismic magnitude, if the breakage extends to the shallow depth of the segment hardness, the produced tsunami is larger than the break.

"In the diverter strip, the upper plate is thinner, the hardness is thinner, the hardness is lower," said Cheung explained. "The ground-in-the-seismometer recorded on the concentrated neutral or shallow rupture is relatively weak, but the displacement in the over-sea has a stronger energy and produces shorter tsunami waves, when they move to the coast Higher speed is large.
