With no warning Saturday night, the giant wave slammed into tourist beaches and coastal areas along the Sunda Straight, to the west of Jakarta.
The wave destroyed hundreds of buildings and injured some 700 people.
At least 160 people have been reported dead... and about 30 are still missing.
According to Indonesia's geophysics agency, the tsunami might have been triggered by undersea landslides caused by the eruption of the nearby Krakatoa volcano, which began on Friday.
Indonesian seismologists have warned of the possibility of additional damage from high waters until Tuesday.
An official from the South Korean Embassy in Indonesia said that seven Korean tourists at a beach that was hit... were able to flee to a safe place and were not injured.
The Korean foreign ministry says it has sent messages to Korean nationals living in Indonesia advising them to stay safe and offering help if they need it.
The ministry says it will continue to monitor the safety of Korean citizens there and provide help promptly if Koreans report any injuries or other damage.
