2010 eruptions of Mount Merapi continued to push its way up into the volcano's lava dome. A pyroclastic river flowed from Merapi again on 30 October 2010 at 00:35. A pyroclastic flow headed toward Gendol River, Kuning River, Krasak River, and Boyong River. This was then followed by an explosion from Merapi resulting in a two-kilometre vertical high fire ball rising from the top of the mountain . This eruption caused raining sand to fall on areas to a radius of up to from the volcano. Amongst activities from government and NGO's the Indonesian Red Cross and Red Crescent (PMI) had by this time fielded
2004 Indian Ocean earthquake and tsunami floor to pop up in seconds. This quickly elevated the height and increased the speed of waves, destroying the nearby Indonesian town of Lhoknga. Indonesia lies between the Pacific Ring of Fire along the north-eastern islands adjacent to New Guinea, and the Alpide belt that runs along the south and west from Sumatra, Java, Bali, Flores to Timor. The 2002 Sumatra earthquake is believed to have been a foreshock, preceding the main event by over two years. Great earthquakes, such as the 2004 Indian Ocean earthquake, are associated with megathrust events in subduction zones. Their seismic moments can account for
