A magnitude 8.6 earthquake shook the Indonesian island of Sumatra at 2:38 p.m. local time on April 11, followed by a magnitude 8.2 aftershock a couple of hours later. The April 11 quake was a strike-slip quake that moved mostly horizontally, and so did not trigger a tsunami like the one seen following the magnitude 9.1 earthquake on December 26, 2004, that killed more than 200,000 people.
