Krakatau (Sunda Strait, Indonesia): The intermittent explosive and near-constant degassing activity from the cinder cone continues.
A couple of vulcanian-sized explosions appeared at the volcano within a seven hours time-span yesterday.

Dense white-to-grey, grey ash plumes rose about 457-657 meters above the crater and drifted to the southwest of the volcano.
The seismic network reported seismic signals with maximum amplitudes of 38 and 46 mm and a duration of 53 and 41 seconds.

Merapi (Central Java, Indonesia): The elevated activity of the volcano continues.
Constant pyroclastic flows continue to travel from the southwestern lava dome as the active basaltic-andesitic lava intrudes into the dome. Therefore, more and more unstable lava material makes the dome prone to collapse towards the steep ravines, which in turn often develop into very dangerous block-and-flows.

Merapi itself has given its name to a style of these types of pyroclastic density currents: Merapi-type. However, once magma properties change its differentiation and pressure to higher levels, this might lead to explosive events on the growing lava dome triggering pyroclastic flows (so-called Peléean type).
