Volcanic eruption in Indonesia forces evacuations and flight cancelations

Key Points

• The Mount Lewotobi Laki Laki volcano erupted again, sending ash plumes up to 5,000 meters and prompting authorities to raise the alert to the highest level with an 8-kilometer no-go zone.
• Authorities evacuated residents from multiple villages and the volcano monitoring post to avoid falling gravel and ash, but no casualties have been reported so far.
• Dozens of flights to and from Bali and Labuan Bajo were canceled or delayed due to the ash cloud, affecting thousands of passengers and prompting airlines to reschedule services.
• The 1,584-meter twin volcano has erupted multiple times this year—including a deadly November blast—and is one of Indonesia’s 120 active volcanoes along the Pacific “Ring of Fire.”

LEMBATA, Indonesia (AP) — Indonesia's Mount Lewotobi Laki Laki erupted with giant ash and smoke plumes again Wednesday after forcing evacuations of villages and flight cancelations, including to and from the resort island of Bali.

Several eruptions sent ash up to 5,000 meters (16,400 feet) into the sky Tuesday evening to Wednesday afternoon. An eruption Tuesday afternoon sent thick, gray clouds 10,000 meters (about 32,800 feet) into the sky that expanded into a mushroom-shaped ash cloud visible as much as 150 kilometers (nearly 93 miles) away.

The eruption alert was raised Tuesday to the highest level and the danger zone where people are recommended to leave was expanded to 8 kilometers (about 5 miles) from the crater.

Officers also evacuated from the Mount Lewotobi Laki Laki monitoring post 7 kilometers (4.3 miles) from the crater to avoid falling gravel released in the eruption. No casualties have been reported.

Ash and debris fell in a number of places outside the danger zone, including the villages of Boru, Hewa and Watobuku. Some residents from Nurabelen village in Ile Bura subdistrict fled to evacuation sites in Konga to avoid the impact of the eruption, the National Disaster Management Agency said in a statement.

“Some residents have also evacuated to Nileknoheng village, which is 12 kilometers (7.4 miles) from the crater,” said Abdul Muhari, the National Disaster Management Agency’s spokesperson.

Dozens of flights Wednesday were canceled, including those connecting Bali to cities in Australia, Malaysia, India and China, according to the website of Bali's I Gusti Ngurah Rai International Airport. Volcanic ash can pose a risk to plane engines.

Flights also were canceled to and from the international airport in Labuan Bajo another tourist destination in Flores Island, East Nusa Tenggara province. The airport is still operating.

The cancelations and delays affected thousands of travelers. Australian carrier Jetstar, which flies daily between the tourist hotspot and several Australian cities, said the ash cloud was forecast to clear by late Wednesday and its services would be rescheduled.

Air New Zealand cancelled one return trip to Auckland and would rebook customers on the next available service, the airline said in a statement Wednesday. Flights to New Delhi, Singapore and Pudong, China, were also cancelled due to the volcano, according to information on the website for Denpasar airport in Bali.

The 1,584-meter (5,197-foot) Mount Lewotobi Laki Laki is a twin volcano with Mount Lewotobi Perempuan in the district of Flores Timur.

The volcano has had several eruptions, and its danger level and no-go zone have changed several times before being raised again to the highest level Tuesday.

An eruption of Mount Lewotobi Laki Laki in November killed nine people and injured dozens. It also erupted in March.

Indonesia is an archipelago of 270 million people with frequent seismic activity. It has 120 active volcanoes and sits along the “Ring of Fire,” a horseshoe-shaped series of seismic fault lines encircling the Pacific Basin.
