Honshu Earthquake Measured by Seismic Station at PEA
The seismic station that was installed by the Royal Observatory of Belgium at the Princess Elisabeth Station in Antarctica has recorded the earthquake that hit the eastern shores of Honshu in Japan on March 11th, 2011.
“ELIB” as the station is named, helps scientists to gather unique information on the lithosphere and seismic activity in the eastern part of Antarctica. Unlike many other seismic stations in Antarctica, ELIB was installed in rock instead of ice, some 300 meters from the station.
ELIB recorded the waves generated by the Japanese earthquake, with a magnitude of 8.9 (11/03/2011 05:46:23), which propagated through the Earth’s interior before being recorded 16 minutes later in Utsteinen, 15 000 km away.
