WATCH: Indonesia’s Mount Semeru volcano erupts as alert status raised
No casualties have been reported, but the eruption could cause a tsunami in Japan.

Indonesia’s Mount Semeru erupted Sunday, spewing hot ash clouds a mile into the sky, prompting authorities to raise the volcano’s alert status to the highest level.
The eruption of the highest mountain on Indonesia’s main island of Java around 800 kilometres southeast of capital Jakarta sparked evacuations of nearby villages.
The increased threat level “means the danger has threatened the people’s settlement and the volcano’s activity has escalated,” Volcanology and Geological Disaster Mitigation Center (PVMBG) spokesperson Hendra Gunawan told broadcaster Kompas TV.
“Japan’s weather agency warned that a tsunami could arrive at the islands of Miyako and Yaeyama in the southern prefecture of Okinawa,” Kyodo news agency reported.
It said the tsunami could arrive by 2:30 pm local time (0530 GMT) but there were no reports of any damage an hour after that time had passed.
“Hot avalanches” caused by piles of lave at the tip of the volcano slid down after the eruption, National Disaster Mitigation Agency spokesperson Abdul Muhari said.
No casualties or injuries were immediately reported after the eruption but Gunawan warned nearby residents not to travel within eight kilometres (five miles) of the crater after the threat level was raised to four.
Shelters were being prepared for residents who were evacuating, the official said.
They were also told to avoid a southeastern area 13 kilometres (8 miles) along a river in the direction where the ash was travelling.
“A lot of people have started to go down,” Thoriqul Haq, the local administration chief for Lumajang, where the volcano is located, told broadcaster Kompas TV.
Villagers flee
Thousands of villagers living near Indonesia’s Mount Semeru were racing for refuge on Sunday to the wail of emergency sirens as lava snaked towards their homes under a black sky after the volcano erupted.
Locals fled on motorbikes sometimes three at a time as a mushroom cloud of ash approached and monsoon rains lashed the area in East Java.
“It was dark and raining. The rain did not consist only of water, but also volcanic ash. It was like mud,” said an AFP journalist on the scene.
One emergency responder, Gunawan, filmed the clouds above as a midday sky turned ominously dark as though midnight.
“It’s getting dark, bro,” he said to the camera as a seismograph whistled in the background.
The internet was down and phone signals were patchy but villagers were alerted to the danger by sirens and the beating of bamboo drums by local volunteers.
Many villagers, mostly women and children, took shelter in local halls and schools, some as far as 20 kilometres away.
Gunawan, who like many Indonesians goes by only one name, said everyone was safe for now, even if their possessions and homes might not be by day’s end.
One year after last eruption
Mount Semeru last erupted exactly one year ago, killing at least 51 people.
The disaster left entire streets filled with mud and ash, swallowing homes and vehicles, with nearly 10 000 people seeking refuge.
Semeru’s alert status had remained at its second-highest level since its previous major eruption in December 2020, which also forced thousands to flee and left villages covered.
Indonesia sits on the Pacific Ring of Fire, where the meeting of continental plates causes high volcanic and seismic activity.
The Southeast Asian archipelago nation has nearly 130 active volcanoes.
In late 2018, a volcano in the strait between Java and Sumatra islands erupted, causing an underwater landslide and tsunami which killed more than 400 people.
