People living in the southern coastal region of Java, Indonesia, are encouraged to always be aware of the possibility of natural disasters such as earthquakes and tsunamis, given that the area is now considered part of the active earthquake zone.
This can be seen by the frequent occurrence of so-called "swarm earthquakes" or "small-scale earthquakes" that do not end with a major earthquake. The data were obtained by studying the results of the evaluation of the seismic activity during the month of August 2019.
This was stated by the Head of the Agency for Mitigation, Meteorology, Climatology and Geophysics of Earthquakes and Tsunamis (BMKG), Daryono, at a press conference held on Friday (08/30/2019) at the National Agency for Disaster Management Graha (BNPB), Jakarta.
However, Daryono emphasized that although the Java Suer is an active earthquake zone, this does not mean that there should be a major earthquake.
According to Daryono, the earthquake that shook southern Banten in early August 2019 was a warning that there was an active earthquake zone in the southern part of Java.
That is why, according to Daryono, people living in the area must be prepared to face earthquakes or tsunamis and not ignore the warnings that have been given.
One of the ways to deal with natural disasters is prevention. Is is mandatory to build houses that are designed to withstand future earthquakes. In addition, a "safe spaces" plan must be created, to avoid to build on the beaches or lands susceptible to get damaged by earthquakes and tsunamis.
The Head of the Agency stated that experts should continue studying the disasters. The Indonesian people, on the other hand, must be attentive, since they live in disaster-prone areas, but there is no need to worry more.
The Head of the Earthquake and Tsunami Mitigation Section of BMKG mentioned several areas that were included in the active earthquake zone in September 2019. These areas include Mentawai-Nias, the Sunda and South parts of the island of Java, the South of Bali-Sumbawa-Sumba, Central Sulawesi-Gorontalo, the Ambon-Banda Sea, the North Maluku Sea, and Mamberamo and its surroundings.
Daryono admitted that in the results of BMKG statistics, from January to August of this year, the trend in the area has diminished. However, he warned that the decrease in seismic activity in these areas did not mean that there was no earthquake risk.
According to BMKG monitoring results, in August 2019, tectonic earthquakes were recorded 673 times. The number has decreased compared to July 2019, where 841 movements were register.
