Hanoi (VNA) –
Mount Merapi, the most active volcano in Indonesia, erupted on March 27, spewing a column of ash of up to 5km high, forcing local authorities to issue a flight warning.

The volcano, situated in the main Java Island, started erupting at 10:56 am (Jakarta time), the Center for Research and Development of Geological Disaster Technology of the Volcanology Agency in Yogyakarta province said in a statement.

The wind blows to the southwest of the crater, it said.

The agency heightened the volcano observatory notice for aviation (VONA) to the highest level with a red code from the green-code normal level.

The red code means that planes are banned from flying through the air space above the area around the volcano.

Residents are prohibited from having activities in a radius of 3 km from the crater.

The volcano last erupted on March 3, spewing a column of ash of up to 6km to the sky.

The 2,930 meter-high Mount Merapi, one of Indonesia's 129 active volcanoes, has regularly erupted since 1548.

During its eruption from October to November 2010, a total of 353 people were killed and about 350,000 others were forced to evacuate.

Indonesia, a vast archipelagic nation, is prone to volcanic activities and earthquakes as it lies along the so-called "Pacific Ring of Fire."/.
