On 20 October 2010, the Indonesian government raised the alert for Mount Merapi to its highest level and warned villagers in threatened areas to move to safer ground. People living within the range of a zone were told to evacuate. Officials said about 500 volcanic earthquakes had been recorded on the mountain over the weekend of 23–24 October, and that the magma had risen to about below the surface due to the seismic activity. On the afternoon of 25 October 2010, Mount Merapi erupted lava from its southern and southeastern slopes.
