Weak strombolian activity continues at the Bocca Nuova crater of Etna volcano [4].

Another weak seismic swarm is occurring at the Tjörnes Fracture Zone [5] north of Iceland. It is probably tectonic in nature although some active volcanoes probably exist in this area as well.

Fuego volcano [6] has been following its increasing trend of activity with 20 explosions reported between 3-4 Oct and 21 during 4-5 Oct, with ash plumes rising up to 1.2 km. Its violent eruption 3 weeks ago (on 13 Sep) still in mind, local residents and media are getting nervous about this behaviour.

Santiaguito [7] continues at rather low levels. Some red glow is visible at night and there are occasional weak explosions with ash rising a few 100 meters. Lava flows are active on the NE and SE sides of the cone.

Popocatépetl [8] has increased its activity. During 3-4 Oct, it produced 12 explosions, and 32 during 4-5 Oct, a few of which produces ash plumes up to 1-2 km height. Glow is visible from the crater at night. Seismic activity is low and the alert status remains unchanged.

Some smaller ash emissions occurred at Sheveluch volcano [9] last night and were detected on satellite images.

Sakurajima volcano [10] remains quite active with 5 weak to moderate explosions during the past 24 hours.

Pagan volcano [11] in the Marianas continues to steam, but there has probably not been other activity USGS reports.
