Jakarta, Indonesia: Indonesia’s climate and geophysics agency (BMKG) has advised people to stay away from coastal areas on both sides of the Sunda Strait, where a deadly tsunami struck on the weekend.
The agency said late Tuesday that heavy rain throughout the day was possible on areas surrounding the Mount Anak Krakatau on Wednesday.
“Therefore, we ask people to remain cautious and avoid the beaches or coastal areas within a 500 metre to 1-kilometre radius,” said agency head Dwikorita Karnawati.
The tsunami that has killed over 420 people came without warning as Indonesia lacks the system to detect tsunamis triggered by undersea landslides and volcanic eruptions.
Scientists have concluded that the tsunami was triggered by undersea landslide, preceded by eruptions from the Mount Anak Krakatau volcano.
Karnawati said the agency has developed an application that can monitor the volcano’s seismic activity, so warnings can be issued sooner in future.
The tsunami struck coastal areas in Banten province on the western tip of Java and Lampung province on the southern tip of Sumatra just four days ahead of the 14th anniversary of Indian Ocean tsunami that killed more than 200,000 people in Aceh province on Dec 26, 2004.
