Antarctic icequakes triggered by 2010 magnitude 8.8 Chile earthquake

Sections of Antarctica’s frozen desert can experience hundreds of micro-quakes an hour due to ice deformation. These quakes are also called icequakes and they are a usual occurrence on Antarctica. However, after the 8.8-magnitude earthquake that hit Chile in March 2010 Antarctica’s icesheats vibrated a bit more than usual. The event was investigated by scientists from Georgia Institute of Technology which indicated in their new study that Antarctica’s frozen ground is sensitive to seismic waves from distant earthquakes.To study the quake’s impact on Antarctica, the Georgia Tech team looked at seismic data from 42 stations in the six hours before and after the 3:34 a.m. event. The researchers used the same technology that allowed the… »
