On 25 October 2010 the Indonesian government raised the alert for Mount Merapi to its highest level (4) and warned villagers in threatened areas to move to safer ground. People living within a 10 km (6.2 mi) zone were told to evacuate. The evacuation orders affected at least 19,000 people however the number that complied at the time remained unclear to authorities.[10] 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 a 1 km (3,300 ft) below the surface due to the seismic activity.
