Unlike the magnitude 9.1 quake that struck the region in December 2004, these tremors did not trigger a deadly tsunami.

This material can stay airborne, reflecting sunlight and temporarily cooling the Earth. Now, scientists say a series of volcanic eruptions centuries ago may have started a cooling period known as the Little Ice Age.
