Indonesia.RumahNews.com - Research results presented by the Sri Widiyantoro Bandung Institute of Technology (ITB) research team found the potential for an earthquake and tsunami in the southern region of Java Island. The research was based on earthquake data from the BMKG catalog and the International Seismological Center (ISC) from April 2009 to November 2018 and looked at GPS data from 37 stations installed in Central Java and East Java for 6 years.

 Regarding these findings, Indonesia was originally hit by a massive tsunami many times. The following Okezone summarizes the tsunami waves that have occurred in various regions in Indonesia:

 1. Aceh Tsunami 2004

 The tsunami waves that hit Aceh on December 26, 2004, of course, still make an impression on the memory. Waves as high as 35 meters not only destroyed Aceh but also spread to the west coast of Sumatra.

 Based on available data, this incident claimed approximately 170,000 lives. Many residents lost their families in the incident. In fact, the loss due to the disaster is estimated to have reached Rp.

 2. 2006 Pangandaran Tsunami

 On July 17, 2006, a series of earthquakes occurred on the southern coast of Java Island which was followed by a tsunami wave. Based on data from the National Earthquake Center of the Meteorology and Geophysics Agency (PGN BMG), the earthquake that occurred in the Pangandaran coastal area occurred at 15:19 WIB with a magnitude of 6.8.

 The epicenter was located south of Pameungpeuk Beach with a distance of about 150 km, and a depth of 30 km. This location is the junction zone of the two continental plates of Indo-Australia and Eurasia at a depth of less than 30 km. The disaster killed 668 people and disappeared.

 3. Palu Tsunami 2018

 On September 28, 2018, at 18.02 WITA, an earthquake with a magnitude of 7.4, followed by a 5 meter tsunami wave hit Palu and Donggala, Central Sulawesi. The epicenter of the earthquake was reported to be 26 km north of Donggala and 80 km northwest of Palu City.

 Based on BNPB data that the death toll reached 2,045 people, it was found that the most were in Palu with 1,636 people and followed by Sigi and Parigi. Meanwhile, 82,775 people were displaced, and 8,731 people were refugees outside Sulawesi.

 

 It was recorded that 66,390 houses were damaged. This natural disaster is one of the worst. This is because the earthquake caused a five-meter tsunami and liquefaction (soil liquefaction) which caused the ground to move, destroying houses and claiming thousands of victims.

 4.Sunda Strait Tsunami 2018

 The tsunami waves that hit the coasts of Banten and Lampung, on Saturday, 22 December 2018 night, caused 437 people to die, and thousands of people were injured, and dozens missing.
