TEMPO.CO, Jakarta - A tsunami struck the coastal areas of Banten and South Lampung on late Saturday, December 22. The National Disaster Mangement Agency (BNPB) recorded that 281 people have died and more than 1,000 injured, and many went missing.
Sunda Strait tsunami is considered different as it did not cause by an earthquake. The following is five facts about the tsunami in the coastal areas of Sunda Strait per the second day of the disaster, Monday, December 24.
1. The tsunami occurred due to the eruption of Mount Anak Krakatau
The Meteorology, Climatology, and Geophysics Agency (BMKG) said eruption of Mount Anak Krakatau (child of Mount Krakatoa) was allegedly the cause of the tsunami in the coastal beach of Banten and Lampung. The eruption occurred at 21:17 local times, and that triggered high waves.
2. Double natural phenomenon
Other than eruption, according to BMKG chairman Rahmat Triyono, the tsunami was also likely due to tidal wave caused by the full moon.
“There is an indication that high waves, full moon, and also an eruption of Mount Anak Krakatau that occur are considered as the cause of the tsunami," said Rachmat yesterday, December 23.
BMKG on Saturday at 7 a.m had issued an early warning of two-meter high tide in the waters of Sunda Strait which is valid until December 25, 2018. And high waves that caused a tsunami were formed by the eruption of Mount Anak Krakatau.
