Powerful M 5.4 aftershock strikes the Chile coast

Earthquake Report comment :
Aftershocks continue to rattle the Chile February 27 main earthquake area.  Epicenter today was in the coastal area about 40 km from San Antonio.  The quake occurred at 1:46 AM.  By experience we know that most Chile people do not wake up for aftershocks, although this one will be a limit case.
Most aftershocks have a hypocenter in between 25 and 35 km, the same depth than the main earthquake of M 8.8 on February 27.
