Can the Mentawai Earthquake Set off Earthquakes in Different Areas? That is the BMKG’s phrase

Jakarta, CNBC Indonesia – The Meteorology, Climatology and Geophysics Company (BMKG) revealed that the M6.9 earthquake that rocked the Mentawai Islands, West Sumatra (West Sumatra) was triggered by the subduction exercise of the Indo-Australia plate and is included within the megathrust occasion class. Can this earthquake set off earthquakes in different areas?

Head of Earthquake and Tsunami BMKG Daryono opened his voice about this. Based on Daryono, there’s a tendency for earthquakes that happen in a single section to trigger disruption to different segments.

“We see that the Mentawai Siberut megathrust section is adjoining to the Batu section (Nias) after which to the north is the Nias section, Simeulue. Truly when there was a giant earthquake there was a change in constructive stress, so it brought about disturbances subsequent to it,” stated Daryono throughout a gathering press on-line, Tuesday (25/4/2023).

Nonetheless, it needs to be famous, there are a number of elements which are potential mills for earthquakes. For instance, are the opposite segments in a mature situation or at their most with an unstable place or not. If that’s the case, then the potential for earthquakes in different segments might happen.

“However we now have to be sure that the segments which are close by are ripe, and are already at their most, and their positions are unstable, so once they get an emulsion they’ll expertise vitality launch,” he stated.

Based on BMKG data, there have been a number of earthquakes which have had an influence on earthquakes in different segments. For instance the earthquake that occurred in Luwu, South Sulawesi in 2018 triggered an earthquake on the appropriate and left segments. Nonetheless, this didn’t occur within the earthquake on Simeuleu Island, Aceh in 2004 with a magnitude of M8.5 which didn’t set off earthquakes in different segments.

Daryono emphasised that this can be a problem for consultants to research the very mysterious nature of nature. In order that there should nonetheless be catastrophe mitigation to cut back the quantity of people that grow to be victims of the influence of the earthquake.

“So crucial factor is to know that the megathrust zone and Sumatra are an energetic section and have the potential for giant earthquakes to happen. So prefer it or not, prefer it or not we now have to construct a mitigation system, put together something associated to associated structural and non-structural infrastructure. with the capability of the group and we need not decide whether or not this will probably be launched or not, however what is for certain is that your entire megathrust zone has the potential for such an earthquake and that must be anticipated,” concluded Daryono.
