O Departamento de Geofísica do IAG-USP promove nesta quinta-feira, 20 de abril, o seminário: Using radiated Seismic Energy to Identify Tsunami Earthquakes, Anomalous Ruptures, and its benefits to Earthquake Early Warning Systems. O seminário será apresentado pelo Dr. Jaime Andres Convers (IAG/USP).

Data: 20/04/2017 - 16:30

Local: Auditório 1 do IAG (Rua do Matão, 1226, Cidade Universitária)

O seminário do Departamento de Geofísica será apresentado pelo Dr. Jaime Andres Convers (IAG/USP).

A participação é gratuita e não precisa de inscrição prévia.

Resumo:

While a rapid calculation of the seismic moment of an earthquake will concentrate on its static parameters, a look at the radiated seismic energy will help elucidate its dynamic rupture process. I will look at the radiated seismic energy, calculated at teleseismic distances for large earthquakes globally, with special attention to a variety of shallow slow rupturing earthquakes called “tsunami earthquakes”.

While any earthquake that generates a tsunami is classified as “tsunamigenic”, a “tsunami earthquake” is characterized by typically generating a larger wave than expected from its size. Characterized with weaker shaking as perceived by the local population, and a slower rupture, this type of earthquakes from their radiated seismic signature.

Beyond classifying these anomalous-rupturing earthquakes, I will show the application of this methodology for early warning purposes, and how the use of radiated seismic energy not only classifies the aforementioned earthquakes, but also shines a light into rapidly assessing useful dynamic parameters for larger ruptures.
