BNPB asks South Coast of Java to mitigate the impact of earthquake and tsunami

Jakarta (ANTARA) – The National Disaster Mitigation Agency (BNPB) has urged policy makers, communities and all components of coastal areas in South Java to mitigate the potential impact of the earthquake and tsunami.

“We remind policy makers, communities and all components in each of the (southern coastal) zones to increase their preparedness and vigilance to mitigate the potential impact of an earthquake and tsunami,” said Abdul Muhari, said in a press release received here on Sunday.

BNPB hopes that the Earthquake and Tsunami Resilience Village (Destana) set up in 2019 along the southern coast of the island of Java can continue to pioneer community resilience in disaster management.

This idea follows a series of earthquakes that hit the southern part of the island of Java, including a magnitude 5.4 earthquake in the southern part of East Java on Saturday July 9 at 03:17. local hour.

According to monitoring results from the Meteorology, Climatology and Geophysics Agency (BMKG), the earthquake was centered at 9.64 degrees south latitude and 112.91 degrees east longitude at a depth of 10 kilometers. .

“Lumajang District Regional Disaster Mitigation Agency (BPBD) reported to BNPB Control and Operation Center (Pusdalops) that most of the people in Lumajang District suddenly woke up and fled their homes. when the earthquake shook for 2-3 seconds,” Muhari informed.

Less than three hours after the 5.4 magnitude earthquake, BMKG released another earthquake news at 05:50 local time. The second magnitude 5.0 earthquake was centered at 9.57 degrees south latitude and 113.93 degrees east longitude at a depth of 10 kilometers. No shock was felt by the community for the replica.

At 9:53 a.m. local time, the BMKG seismograph recorded another earthquake with a magnitude of 5.3 located at 9.61 degrees south latitude and 112.91 degrees east longitude at a depth of 42 kilometers. According to the Lumajang district BPBD, tremors from the third quake were felt for one to two seconds, but did not cause panic among residents.

Results of an interim BMKG analysis showed the series of earthquakes to be shallow earthquakes due to plate subduction activity. The results of the source mechanism analysis showed that the earthquake has a thrust fault mechanism.

Based on BMKG records at 11:00 a.m. local time, there were 54 aftershocks with the largest magnitude, M 5.0. Of the whole incident of the seismic phenomenon, BMKG assured that the earthquake did not have the potential of a tsunami.

“Results of field monitoring by BPBD of Lumajang District and BPBD of Malang District indicated that no damage was caused. There were also no reports of casualties,” he confirmed.

Based on the InaRisk BNPB seismic risk assessment index, the southern region of Java Island has a moderate to high level of risk. The southern region of the island of Java is also known to be crossed by the Indo-Australian plate which extends from the tip of the western part of the island of Sumatra to the waters of southeastern Maluku, before to finally meet the Eurasian plate and the Pacific plate.

The seismic phenomenon can cause several deaths by the ruins of buildings during strong earthquakes. For this reason, the reinforcement of the building structure, in particular the pillars of the house and the roof structure, should be carried out in stages, both independently and with the support of village funds.
