Mount Agung Volcano Monitoring 2017

Start Date

November 21, 2017

Overview

Mt. Agung Volcano Monitoring The NASA Disasters Program is continuing to closely monitor the Mt. Agung volcano on the Indonesian Island of Bali.  Eruptions of the volcano on November 21st and 25th followed numerous earthquakes in the region.  Currently over 29,000 people have been evacuated from the area surrounding the volcano, and the island’s main airport has been closed.  The last time Agung erupted, in 1963-64, the blast was comparable to the 1980 eruption of Mt. St. Helens, causing over 1,000 fatalities and sending ash and debris 8-10 km into the atmosphere.
