Web11 de out. de 2016 · Her project is using brand new technology to generate tsunami-like waves in a laboratory, where the effects of tsunami on coastal buildings can be measured. The research team built a series of flumes - huge tanks which generate mini-tsunamis - with which they run tests using model buildings to assess the damage caused. WebIn seismology, a tsunami earthquake is an earthquake which triggers a tsunami of significantly greater magnitude, as measured by shorter-period seismic waves. The term was introduced by Japanese seismologist Hiroo Kanamori in 1972. [1] Such events are a result of relatively slow rupture velocities.
