The following chronology of October 26, 2010 eruption of Merapi even a one-year return tomorrow we commemorate.Page YOGYAKARTA Also mourning as deep-dalamya reply to all the victims of the disaster.
At 16:00 pm TowardsVolcanic activity is still likely to rise, after the rise in status to "Beware" since the day before. Visually through the camera that is placed on the slopes of Merapi observation posts could not be observed directly because of thick fog closed since a few hours earlier (photo lower left corner). Even the posts on the slopes of Merapi was reported that they could not visually monitor. HT communication through the radio network.
At 16:00 to 17:00 pmThere was a significant increase in activity include volcanic earthquakes, multiphase (MP), avalanches, etc.. But it is still considered not 'quite' dangerous. There was no visual images at all. All just depends on the tools. Had there are a number of national media interviews by the relevant officers possibilities / scenarios that an eruption will occur.
At 5:00 p.m. to 17:30 pmBeen a surge of volcanic activity are very sharp, especially starting at 17:02 pm, which turned out to be hot clouds glide. Four seismograph had recorded all of the vibration amplitude is very wide (large), even the needle was detached repeatedly. Monitoring officers began frantically busy and remarkable, especially because of the large amplitude and duration of events. Observation posts on the slopes was also reported Thus, it's just not known, what is a cloud of hot / others. All covered with thick fog. No one can guess what's behind the thick fog.
17:30 pm - 18:30 pmThe fog was very thick and getting dark. Increasingly difficult to find out what's happening at Merapi. Four seismograph records the vibrations are still very large (and again several times until the needle off, and rolls of paper is replaced quickly - but normally 12 hours). Officials said there 3 times & eruption clouds glide heat and the possibility of explosive spread in all directions. Memperintahkan center officials on all postal clerk on the slopes of Merapi to immediately leave the post, down to the evacuation. Officers also contacted the officers are in some places, do forced evacuation order for residents. Sirens sounded in various places. HT radio network started very crowded, so did the telephone network in the post. Several officers looked very panicked (crying?), While continuing to pray and bertakbir.
At 18:30 to 19:00 pmCenter officials issued a statement / official information on the media, about the occurrence of this eruption, and the focus now is on the evacuation process. Volcanic activity detected on seismographs began to decline, except a seismograph in Plawangan / Turgo / Kalikuning. Officials worried about Kinahrejo area (where Mbah Maridjan), Kaliadem, and around the southern slope of Merapi.
19:00 pm - ...Officials at the observation posts slopes of Merapi climbed back to their posts (but some are still forbidden to return for a moment). Gravel and ash began to rain reported by the monitoring stations, especially in the area southwest of Merapi. The smell of sulfur can also kiss from around the slopes. Merapi activity is monitored from the seismograph, constantly tends to fall, even the normally quiet stable, although a few times sometimes occur avalanches of material. Visually Merapi is still shrouded in fog, so that no one can can see the 'how big eruption, where the direction of the hot cloud, etc.'. Conditions officials began quietly, even several times seen joking. Journalists and media still continues to standby at the monitoring center, and several follow up to the Ground.
AftermathThe officer stated BPPTK Merapi is currently in a state of deep sleep after the last activity. Not yet known, whether there will be subsequent volcanic activity again. They had time to worry, if that happened last only / new beginning. As the patterns of the previous eruption of Merapi, which is usually small first, then medium, large, reduced, returning to normal again, and so on. The point of the fire / lava flow also could not be confirmed. What happened was greater than that occurred in 2006.Locations affected by the eruption / hot clouds evening before, chances are the areas around the slopes of Merapi, within a radius of 4-6 km, especially the southern slope.Ash / volcanic ash is reported even to Gombong - Kebumen. Evacuation still being conducted.The official version release BPPTK
