JAKARTA, May 1 (Reuters) - Hundreds residents of

Indonesia's Tagulandang island were waiting at the island's port

to be evacuated on Wednesday, footage from National Search and

Rescue Agency showed, while grey smoke continued to erupt from

Ruang volcano.

Indonesia's Ruang volcano erupted on Tuesday, spewing lava

that prompted authorities to evacuate more than 12,000 people

from the nearby Tagulandang island.

The Center for Volcanology and Geological Hazard Mitigation

(PVMBG) raised the alert status of Ruang to the highest level

after yesterday's eruption, and warned the residents of

Tagulandang island that a tsunami could be triggered by volcanic

material collapsing into the ocean.

"Personnel of Manado Search and Rescue Agency are evacuating

109 Tagulandang residents to Munte port, while hundreds are

still waiting in Minanga port to be evacuated," the National

Search and Rescue agency said in a statement on Wednesday.

The residents will be evacuated to North Minahasa Regency on

Indonesia's Sulawesi island.

Transport authorities extended Manado's Sam Ratulangi

airport shutdown until noon (0400 GMT) on Thursday.

Meanwhile carrier AirAsia said in an Instagram post on

Wednesday that flights to and from several cities in Malaysia's

Borneo were affected by the eruption.

Ruang island is about 100 km from Manado, the capital of

North Sulawesi province in the north-central region of the

sprawling Indonesian archipelago.

Indonesia straddles the so-called "Pacific Ring of Fire," an

area of high seismic activity where multiple tectonic plates

meet.
