Scientists from the Bandung Institute of Technology (ITB) declared that there was a possibility of a tsunami of up to 20 meters in the south of the island of Java. The Agency for Meteorology, Climatology and Geophysics (BMKG) said the giant waves only took 20 minutes to reach shore.
“From the results modeling us, in southern Java, only about 20 minutes the tsunami hit the mainland, “said the Head of the Center for Earthquakes and Tsunamis BMKG Rahmat Triyono to detikcom, Friday (9/25/2020).
In southern Java, there is the Sunda Megathrust Line, which is a subduction zone between the India-Australia plate and the Eurasian plate. Sunda Megathrust stretches from the west coast of Sumatra to the Nusa Tenggara Islands. The distance between the islands of Java and Sumatra to the route megaconfidence about 200-250 km. From that route, a large earthquake can occur that can trigger a tsunami.
When a large earthquake with a magnitude (M) of 9.1 occurs in the area megathrust20 minutes later the tsunami waves will hit the beach. The people of the continent will not have much time to save themselves. People in coastal areas are advised not to expect a tsunami watch from the BMKG. Anyway, just run to a safe place.
“If you live near the coast, if you feel a strong shaking, don’t wait warning, because a tsunami is coming soon. Once there is a scare, run. If you wait warningIt means time has been wasted, “Rahmat said.
