Eruption of Mt. Kelud

The volcano sits on the island of Java, about 385 miles east of the capital of Jakarta.

It last erupted in 1990, killing dozens. In 1919, an explosion that blew the top off the mountain killed more than 5,000 people.

Historians say that an eruption in the 16th century took an estimated 10,000 lives.

Surono says the eruption in 1919 happened suddenly and was over relatively quickly for a volcano, lasting six to seven hours — characteristic of what would happen if Kelud were to erupt now.

In fact, scientists say the crater lake currently holding the overheating water was created during the 1919 explosion.

In 1919, about 5,000 died as Kelud ejected scalding water from its crater lake.

On May 19, 1919, an eruption at Kelud killed an estimated 5,000 people, mostly through hot mudflows.
