Authorities in West Sumatra have raised the alert level of Mount Marapi after the volatile volcano began spewing clouds of hot ash late on Saturday.
Pyroclastic clouds over the volcano’s dome were first spotted at 10.33 p.m. on Saturday, officials from the Marapi observation post told local media. The activity continued well into Sunday morning.
The same post also reported a series of minor seismic quakes.
The eruption is considered fairly minor but authorities have issued a warning to locals and hikers to stay beyond a three-kilometer radius from Marapi’s crater.
Authorities also elevated the mountain’s status to the second highest alert level.
The volcano registered a similar eruption on April 13.
Gunung Marapi, not to be confused with the better-known Merapi volcano on Java, is Sumatra’s most active volcano. This massive complex stratovolcano rises 2000 m above the Bukittinggi plain in the Padang Highlands. A broad summit contains multiple partially overlapping summit craters constructed within the small 1.4-km-wide Bancah caldera. The summit craters are located along an ENE-WSW line, with volcanism migrating to the west. More than 50 eruptions, typically consisting of small-to-moderate explosive activity, have been recorded since the end of the 18th century; no lava flows outside the summit craters have been reported in historical time.
