Jakarta: About 550 people fled from their homes on Tuesday after the Semeru volcano on Indonesia's main Java Island erupted, spewing incandescent lava and hot smoke, according to the National Disaster Management Agency.
National Disaster Management Agency spokesperson Raditya Jati said that 300 of these people fled to an observation post, and the rest stayed at shelters, reports Xinhua news agency.
The volcano, located in the Lumajang district of the East Java province, erupted at 1.23 a.m. on Tuesday.

At 3 a.m., there was a downpour leading to the rainwater mixing with the volcanic ash around the observation post.
"We estimate this condition happened due to the quite strong potential hot lava," Jati said.
Currently, the status of the volcano's activity is at the second-highest level or Caution.
The villages affected by the volcanic activities included Supiturang, Oro-oro Ombo, Rowobaung and Sumberwuluh, all in the Lumajang district, he said.
"There are several urgent needs, such as ready-to-eat foods, public kitchens, and masks," Jati said.
The Centre for Volcanology and Geological Hazard Mitigation has recommended residents not to carry out any activities in the danger zone within a radius of 1 km from the volcano's summit, and of 4 km on its south-southeast slope.
