Etna (Sicily, Italy): Activity has dropped again abruptly (and so the tremor signal).

...28 Jan:
A new eruptive phase has started at Bocca Nuova. Since this morning (28 Jan), small ash emissions have been observed and now at night, glow can be seen. The tremor signal has been rising as well.

White Island (New Zealand): Seismic activity has changed from continuous volcanic tremor to a pattern of intermittent tremor. When occurring, the volcanic tremor remains strong. GNS does not think that an eruption is imminent, but reports that the vigorous hydrothermal activity is throwing out rocks and mud and might be followed by ash emissions:
From the latest GNS report:
The crater lake is drying out and produces frequent vigorous bursts of mud, steam and gas. During the last few days, such bursts have thrown mud and rock several tens of meters out from the lake area. Steam and gas clouds above the volcano are often visible from the Bay of Plenty coastline.

Mammoth Mountain (California, USA): Another small earthquake swarm occurred under the (dormant) volcano during 28-29 Jan. Numerous tiny quakes were registered at shallow depths (mostly 1-5 km).

Colima (Western Mexico): A relatively vigorous seismic swarm is taking place.

Popocatépetl (Central Mexico): After a short, intense peak 3 days ago, the rate of emissions has fallen to 8 during 27-28 Jan (1 every 3 hours). However, gas (SO2) emission remains strong and glow at the summit indicates continuing slow magma supply.
