The Recent Megaeruption in Indonesia; Mount Batur

The Mount Batur volcano in Indonesia produced one of the largest volcanic eruptions in the entire regions of southeast Asia in the last 1 million years. This eruption caused a 3,800 meter tall volcano to almost completely collapse, covering the vicinity in more than 120 meters or 390 feet thick of ash. A mere 10,000 years after this eruption occurred, a second caldera collapse was generated due to the volcano's volatile rich magma chamber. So, how long ago did these two massive eruptions occur? This video will answer this question and discuss the caldera forming eruptions.
