JAKARTA, NETRALNEWS.COM - The Meteorology, Climatology and Geophysics Agency (BMKG) noted that Indonesia has been hit by significant tectonic earthquake eight times over the past three days from Wednesday (3/25/2020) to Friday (3/27/2020).
"This is felt by the people who are close to the epicenter," said Head of the BMKG Earthquake and Tsunami Center Rahmat Triyono in a written statement received in Jakarta on Friday (3/27/2020).
The tectonic earthquakes were triggered by the activity of earthquake sources, both the source of subduction plates and active faults scattered in several areas.
These areas include southern Sunda Strait, southern East Java, southern Bali, East Nusa Tenggara (NTT), South Sulawesi, North Sulawesi, North Maluku and Papua.
He detailed the earthquake that occurred in the last three days beginning on Wednesday (25/3) where recorded four tectonic earthquakes felt including Jailolo earthquake. This was triggered by an active fault of magnitude 2.1 at 16.54 WIB.
Then on the same day the Yahukimo earthquake, Papua, was caused by an activity of magnitude rising in the middle mountain with a magnitude of 4.5 at 17.54 West Indonesia Time and Ende earthquake, NTT due to active fault activity with a magnitude of 3.3 magnitude at 16.23 West Indonesia Time.
Furthermore, on Thursday (3/26) two tectonic earthquakes were felt, namely the southern earthquake of the Sunda Strait. This was triggered by a Mentawai fault with a magnitude of 4.2 at 16:23 WIB. Then the second is the Mindanao earthquake, Philippines due to plate subduction activity in the Cotabato Trench with a magnitude of 6.1.
For the earthquake in Mindanao, Philippines, he said, the impact was in the form of shocks felt in parts of North Sulawesi Province at 22.38 West Indonesia Time.
While on Friday, BMKG had recorded three times the tectonic earthquake felt. First, namely the Sarmi earthquake in Papua, which was triggered by a fault that rose to magnitude 5.8 at 04.36 WIB.
Secondly, the earthquake in the southwest of Jember, East Java at 03.35 West Indonesia Time with a magnitude of 4.9 triggered by sea floor fault activity. The last was the Wajo earthquake in South Sulawesi, which was triggered by a walanae fault activity of magnitude 4.9 at 04.58 West Indonesia Time.
The entire earthquake that occurred since Wednesday (3/25) has not caused damage. Most have an intensity scale between II to III Modified Mercally Intensity (MMI).
"This means the shocks felt by the community were as if a truck had passed," he said.
In addition, to this day aftershock activity in southern Bali is still ongoing. BMKG noted that since a major earthquake of magnitude 6.3 occurred on March 19, 2020 until Friday at 00.00 West Indonesia Time, 54 aftershocks occurred.
The increase in earthquake activity lately should be watched out by the community because these events can occur at any time and even today cannot be predicted.
"So the community needs to understand how to save themselves in the event of an earthquake and tsunami. One of them is preparing earthquake-safe buildings and coastal spatial planning based on the risk of tsunami disaster," Rahmat Triyono said.
