THE GREAT CHILE EARTHQUAKE OF FEBRUARY 27, 2010
<p>
A record section of vertical ground displacements from 92 GSN stations for the Mw8.8 Chile earthquake of February 28, 2010. Surface waves can be observed making two passes around the globe during the first three hours following the earthquake. The closest station is in Argentina and the most distant one is in Mongolia. The vertical displacements observed are comparable to the 2004 Sumatra-Andaman earthquake (note the scale at the bottom). A M6.9 after- shock is visible for comparative scale, approximately 90 minutes after the mainshock. On-scale, very broadband data from the GSN have provided important new information to characterize the nature and extent of faulting in great earthquakes.
