Alert! The Baribis Fault Could Trigger An Earthquake In West Java

YOGYAKARTA People living in Bekasi Regency, West Java were excited because they were rocked by an earthquake with a magnitude of 4.9. The earthquake occurred on Wednesday, August 20, evening. According to an analysis from the BMKG, the Bekasi earthquake was triggered by Citarum-Baribis fault activity.

The fault is a geological phenomenon in the form of faults in the layer of earth's compilers. These faults can move to trigger earthquakes. In geological science, the existence of faults is natural and natural.

In almost all areas have faults that have the potential to trigger earthquakes. One of the faults that was recently active was the Baribis Fault. Baribis' name itself was taken from the name of the Baribis Hills in Kadipaten, Majalengka, West Java. The name was first introduced by the Dutch geologist Van Bemmelen.

The Baribis fault is one of the active faults in West Java. This fault is thought to be divided into two segments, namely the west and east segments. However, evidence of activeness that can be proven is only the eastern segment. Meanwhile, the western segment of the fault activity is still not proven.

In an article entitled Variation of the Strain around the Baribis Fault Based on the Continuous GPS Observation Data (2016-2018) published in the Ellipsoida Geodesics and Geomatics Journal, it was explained that the Baribis Fault was in the area around the meeting between the Jakarta coastal land zone and the Bogor zone.

In the mainland zone, Jakarta is on the north side of Java which stretches from Serang to Cirebon. Meanwhile, the Bogor zone is in the south of the mainland zone of Jakarta coast. The zone stretches from Tangerang, Bogor, Purwakarta, Majalengka, to Kuningan.

The length of the fault which reaches 25 km makes the Baribis Fault considered the longest on the island of Java. This predicate certainly keeps horror because it can be the source of the earthquake in West Java.

In the journal Bulletin of Scientific Contribution: GEOLOGY, it is said that Sesar Baribis is a young fault. The fault was formed during the PliosenPlistocene tectonic period and is still active today.

In another source, it is also stated that according to the results of geophysics research, the Baribis Fault undergoes movement between 1 to 5 millimeters per year. In addition, several segments of the Baribis Fault are believed to still have great energy potential. This energy can be manifested as an earthquake in the future.

Reporting from the website of the Surkala Indonesia Foundation, Sesar Baribis is said to be the fault responsible for the earthquake that occurred in 1834 in Bogor. At that time the strength of the earthquake reached 7.0 Mw to create mass destruction in the area. The fault returned to movement in tahun 1862 to cause an earthquake in Karawang Regency with a strength of 6.5 Mw.
