Eruptions and pyroclastic flows on Mount Merapi.

Mount Merapi, a 2970 m stratovolcano (cone-shaped volcano made up of layers of ash and lava) in Central Java, considered to be one of Indonesia's most active, erupted on Wednesday 27 January 2021, producing a column of ash 3000 m high away, as well as several new lava streams and pyroclastic flows (avalanches of hot ash and gas). There are no reports of any casualties associated with this eruption, and nor would they be expected, as a 3 km exclusion zone has been in place around the volcano since the current eruption cycle began in November 2020, although a number of elderly people have been evacuated from nearby communities by the Badan Nasional Penanggulangan Bencana.
