Destructive Pyroclastic Flows From Mount Sinabung

Mount Sinabung, located in northern part of the Indonesian island of Sumatra has been undergoing near constant eruptions since September last year.

A pyroclastic flow is a superheated (often with temperatures in excess of 500 degrees Celsius) dust and debris cloud that flows down the volcano. These can flow downhill at extraordinary speeds, often greater than 200km per hour.

Pyroclastic flows are the most destructive hazard from these type of volcanic eruptions. The video above shows one of Sinabung’s pyroclastic flows – made by Photovolcanica.
