Mount Merapi in Yogyakarta
Mount Merapi is located on the South coast of Central Java, Yogyakarta, Indonesia. The volcano has a Summit elevation of 2.968 m (9.737 ft). This is one of the most active volcanoes in Indonesia. According to records, the volcano erupts (peak liveliness) every 2-5 years. Since 1548, the mountain has erupted 68 times. Mount Merapi is located about 25 kilometers from the city of Yogyakarta. On the slopes of the mountain, there is still a settlement to an altitude of 1700 m and is located only 4 kilometers from the peak. Therefore, Mount Merapi became one of 16 volcanoes world.2006 Eruption
In April and May 2006, signs began to emerge that Merapi will erupt, marked by the earthquake. The local Government of Central Java and Yogyakarta has prepared evacuation efforts.
June 1, 2006, Raining volcanic ash from Mount Merapi hot clouds glide. This ashfall can be felt up to a distance of about 14 kilometers.
June 8, 2006, the volcano at 09: 03 PM erupted with bursts of hot clouds that made thousands of residents in the region of Mount Merapi to panic and try to escape to a safe place. A second eruption occurred at 09: 40 pm. Bursts of hot clouds as far as 5 kilometers further to the South.
In late October 2010 the Center for Volcanology and Geological Hazard Mitigation, Geological Agency (CVGHM), (Indonesian language—Pusat Vulkanologi & Mitigasi Bencana Geologi, Badan Geologi-PVMBG), reported that a pattern of increasing seismicity from Merapi had begun to emerge in early September.
Observers at Babadan 7 kilometres (4.3 mi) west and Kaliurang 8 kilometres (5.0 mi) south of the mountain reported hearing an avalanche on 12 September 2010. On 13 September 2010 white plumes were observed rising 800 metres (2,600 ft) above the crater. Lava dome inflation, detected since March, increased from background levels of 0.1 millimetres (0.0039 in) to 0.3 millimetres (0.012 in) per day to a rate of 11 millimetres (0.43 in) per day on 16 September. On 19 September 2010 earthquakes continued to be numerous, and the next day CVGHM raised the Alert Level to 2 (on a scale of 1–4). Lava from Mount Merapi in Central Java began flowing down the Gendol River on 23–24 October signalling the likelihood of an imminent eruption.
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 kilometres (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. 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 1 kilometre (3,300 ft) below the surface due to the seismic activity.
