The major earthquake occurred off the coast of the Maule region of Chile on February 27, 2010 was rated 8.8 on the moment magnitude scale. 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 80 km in the south and 200 km in the north direction along Chilean coastal line.
