"Shortly after the Philippines earthquake, the Pacific Disaster Center Command Post issued a tsunami warning which was received by the National Agency for Disaster Management (BNPB)," said the agency`s Head of Data Information and Public Relations center, Sutopo Purwo Nugroho, in Jakarta on Tuesday.
Sutopo said estimates of the time at which the tsunami is expected to hit and its extent have been issued. Some areas in the Philippines continue to be on standby for a possible tsunami strike.
"Likewise, a number of areas in Indonesia which are located adjacent to the Philippines are also on standby on fears of a tsunami threat to Indonesia," he said.
Areas facing a tsunami threat include Manado, Patani, Sorong, Tarakan, and Jayapura in Northern Indonesia. These areas were predicted to feel the impact three to four hours after the Philippines earthquake.
"It is estimated that the tsunami waves reaching Indonesia will not be too high. Communities are encouraged to remain calm and not panic. (People must) steer clear of marine and coastal activities. We will continue to give out information depending on the prevailing conditions," he said.
