Another burst of volcanic activity from Mount Raung on the Indonesian island of Java prompted authorities to temporarily close airports in Bali due to concerns about volcanic ash. Volcanic ash can cause extensive damage and failures in jet engines. This is the third time this month that Bali’s airport has been forced to close due to volcanic activity, according to news reports.
Mount Raung is a stratovolcano that has erupted at least 13 times in the past 25 years, according to records kept by the Smithsonian Global Volcanism program. The summit stands 3,332 meters (10,932 feet) above sea level and is capped by steep caldera that is 3 kilometers (2 miles) in diameter.
In contrast to the explosive eruptions of the previous week, ash emissions from Mount Redoubt became more frequent but confined to lower altitudes on March 30, 2009. The commercial satellite GeoEye-1 captured a high-resolution view of the volcano the same day.
