BMKG clarified information Maths megathrust M8,7 called threatening Jakarta.
Indonesian megathrust zone (BMKG)
solopos.com, SOLO - Recently appeared information that makes the Indonesian people anxious related megathrust earthquake with the strength to reach magnitude 8.7 that can shake Jakarta. Meteorology, Climatology and Geophysics Agency (BMKG) also provide clarification about the information that has been viral.
The reason, the information mentioned is sourced from BMKG. The institution did clarify the potential for the quake earthquake. but actually BMKG never issued a prediction about when a major earthquake will occur.
Head of BMKG, Dwikorita Karnawati, in a live interview aired TV One, explaining the meaning of the megathrust zone. the zone is a rising fault region that actually lies at the bottom of the Indian Ocean, precisely to the west of the Son of Sumatra and south of Java Island.
"The megathrust zone is a fault zone that may move and be in the Indian Ocean. While the earthquake-prone zone is dependent on local premises. for example our area is locally if there is an earthquake wave, this can be amplified. If there is a wave going into the structure of the harder soil will be muffled, "said Dwikorita.
therefore, what BMKG does is map the zone-zaona condition that would be expected to be amplified by the fault wave. This is the basis for mitigation so that the impact of the earthquake can be minimized. "What we need to remind is the mitigation, for example to make the construction of the building more secure," he continued.
in a statement released by BMKG Public Relation Division at the official website on Friday (2/3/2018), said that the government through the National Earthquake Study Center (Pusgen) and supported by earthquake experts has published the book of Earthquake Source and Danger of Indonesia in 2017 and earthquake mitigation in Indonesia.
"The map is published with a book of the same title.in the book informed that based on the results of the study of earthquake experts, the collision zone between the Indo-Australian Plate and Eurasian, which dip below Java Island is called a megathrust zone, and the process of subducting the plate is still happening at a rate of 60-70 mm peryear, "BMKG wrote in the release.Furthermore, according to the analysis of earthquake experts, the subduction movement of the plate is possible to result in a megathrust earthquake with a maximum strength / magnitude expected to reach M 8.7. From here, BMKG explains how such information can emerge and become viral.
it started when the Alumni Association of Meteorology and Geophysics Academy (IKAMEGA) took the initiative to hold a discussion with the Provincial Government of DKI Jakarta to prepare mitigation measures. the discussion was designed for a limited circle of experts and policy holders for discussing sensitive yet urgent issues regarding public safety.
But it turns out there are some posts that circulate viral and conclusions that appear in the community is considered less precise. bMKG also straightened some things in the paper that became viral it.
"Although experts are able to calculate the maximum Magnitude forecast of earthquakes in the megathrust zone, the current technology has not been able to predict correctly, let alone ascertain when the megathrust earthquake occurred. we have not been able to confirm whether the M8,7 megathrust earthquake will actually happen, when, where, and how much strength? then in such uncertainty, what needs to be done is appropriate mitigation efforts, preparing concrete steps that need to be done immediately to minimize the risk of socio-economic losses and casualties in case the earthquake really happens, especially by preparingcommunity readiness and infrastructure, "BMKG concluded in the release.
