JAKARTA, Indonesia—Mount Semeru, the highest volcano on Indonesia’s most densely populated island of Java, spewed hot clouds as far away as 4.5 kilometers (nearly 3 miles) on Saturday.

There were no immediate evacuations, but the National Disaster Mitigation Agency warned people who live in the villages on the slopes of the 3,676-meter (12,060-foot)-high mountain to be vigilant in looking for signs of danger.
