Sumatra quake felt in Alaska
South-central Alaska's Mount Wrangell rumbled for 11 minutes following the Sumatra earthquake in December 2004. A swarm of 14 earthquakes were triggered at Mount Wrangell about one hour after the initial rupture in Indonesia, more than 6,800 miles away.

Mount Wrangell is an active volcano, that displays frequent steaming and seismicity, but the activity recorded in December gained the attention of scientists at the Alaska Volcano Observatory (AVO) at the Geophysical Institute. Michael West, John J. S?nchez, and Stephen R. McNutt, all of the Alaska Volcano Observatory, authored a paper describing their findings at Mount Wrangell that appear in the scientific journal Science.
