The rupture front of the earthquake was imaged by back projecting teleseismic P-wave energy recorded by United States National Seismic Network. It is found that the earthquake had an asymmetrical bilateral rupture with a dominant direction from south to north. The rupture continued for at least 150 s and extended about 1:chmetcnv w:st="on" UnitName="km" SourceValue="80" HasSpace="False" Negative="False" NumberType="1" TCSC="0">80 km1:chmetcnv> in the south and 1:chmetcnv w:st="on" UnitName="km" SourceValue="200" HasSpace="True" Negative="False" NumberType="1" TCSC="0">200 km1:chmetcnv> in the north direction along Chilean coastal line.
