Two disasters struck Indonesia on the same day of 25 October: The eruption of Mount Merapi and the tsunami that hit the Mentawai Islands.
- Mount Merapi: Seismic activity developed into the eruption of the Mount (Mt.) Merapi volcano and was followed by an earthquake and tsunami approximately 70 km from the Mentawai Islands. The eruption has left 34 people dead, and has displaced more than 70,000 people. A further eruption happened on 1 November 2010.
- Mentawai Islands: The Mentawai Islands were hit by a tsunami initiated by an earthquake measuring 7.7 on the Richter scale. This tsunami wave penetrated 400 metres inland and wiped the beachfront clean at many locations. Bad weather and high sea journeys have hampered the initial stage of response in this operation. More than 15,000 of the total population of Mentawai Island have been affected
