Mount Semeru, a volcano on the Indonesian island of Java, erupted on Saturday, killing at least 13 people, injuring scores of others and causing nearly a thousand evacuations.
Videos posted on social media showed chaos as Indonesians ran through the streets of the island fleeing the ashes and muddy mud.
Other videos show the demolition of a bridge linking the city of Malang with the state of Lumajang, both in Java, an island of about 150 million people on the Indonesian archipelago.
The country’s National Agency for Disaster Countermeasure reported the following day an explosion, which occurred at 3 p.m. At a local event on Saturday, it killed at least 13 people and injured at least 98, according to Reuters.
The center also reported that 902 people had been evacuated, according to a telephone service.
The blast was caused by thunder and rain, local officials told the Associated Press.
Mount Semeru last erupted in January, and no one was killed. It is one of more than 100 volcanoes in Indonesia, located within the “Ring of Fire,” the epicenter of a major earthquake that could cause massive volcanic eruptions.
