The BNPB made the appeal as there is still the possibility for a follow-up tsunami to take place.
"A series Mount Anak Krakatau eruptions is still taking place that could trigger follow-up tsunami," PNPB Spokesman Sutopo Purwo Nugroho said here on Sunday.
He said the safe distance from the beach lines in a number of locations that had been affected by the tsunami varies, depending on the topographies of the regions concerned.
The Sunda Strait tsunami waved the distance from 50 meters from the beach lines to 100 meters.
