They will discuss their work at the 178th ASA Meeting. (2019-12-06)

Stormquakes: Powerful storms cause seafloor tremors
Stormquakes are a phenomenon characterized by seismic activity originating at the ocean floor due to powerful storms. Heavy storms, like hurricanes or nor'easters, can create seismic waves as large as magnitude 3.5 quakes. These tremors caused by the effects of storms on the seafloor are what researchers call stormquakes. Catherine de Groot-Hedlin, who was part of the group that first observed stormquakes, will discuss their properties and meteorological significance at the 178th ASA Meeting. (2019-12-06)
