Reykjanes (Reykjanes peninsula (SW Iceland)): (13 Oct) A shallow (10 km) magnitude 4.8 earthquake with many pre- and aftershocks (or a seismic swarm) occurred this morning (Sun) at 07:34 UTC at the SW tip of the Reykjanes peninsula, on the SW active rift zone. The swarm of earthquakes included several quakes of magnitude 3 and higher. The strongest earthquake was widely felt in SE Iceland.

Whether the earthquakes are related to magma intrusions (a possibility) or purely tectonic is unclear.
Klyuchevskoy (Kamchatka): The eruption continues with little changes; strong strombolian activity / lava fountaining from the summit vent can even be seen on the KVERT webcamera.
Chirpoi (Kurile Islands, Russia): A thermal hot spot remains visible on satellite data, suggesting continuing activity.
Dukono (Halmahera): Sometimes strong strombolian to vulcanian-type explosions continue. An ash plume rose to 8,000 ft Saturday VAAC Darwin reported.
Veniaminof (Alaska Peninsula, USA): Seismicity remains elevated and hot spots remain visible in the caldera on MODIS data. The seismic activity has been gradually declining over the past several days, and no clear views could be obtained from webcam images to see if lava effusion continues.
Popocatépetl (Central Mexico): The number of emissions (mainly steam puffs) has increased to about 3 per hour. A total of 8 small explosions, some of which ejected incandescent tephra outside the crater and produced small ash plumes were observed during the latest 24 hour report interval (CENAPRED).
Fuego (Guatemala): Activity has increased today, the volcano observatory reports in its special bulletin. The number and size of explosions rose and produced incandescent fountains of up to about 200 m and an ash plume rising about 1 km which drifted 8 km S and SW. Shock waves that rattled windows and roofs of houses in nearby villages accompanied the explosions.
The lava effusion increased as well, feeding a new flow that traveled 700 m on the southern flank this morning. Weak to moderate avalanches detached from the flow front. The main hazard would be a further increase of lava emissions and/or a sudden collapse of the lava flow that could produce dangerous pyroclastic flows such as in previous similar eruptive episodes over the past months.
Tungurahua (Ecuador): Continuous strombolian eruptions of fluctuating intensity are observed. This and the presence of a relatively large SO2 plume indicate that the volcano currently has an open conduit allowing fresh magma from deeper storage areas to rise quickly.
Erta Ale (Ethiopia): We are looking for only two more participants to make the expedition to the Danakil (Ethiopia) from 17-29 Nov possible.
This is your chance to visit one of world's most exciting and volcanically impressing places in a small group (max 4 persons) organized by a professional competent tour operator.

Jebel Zubair (Red Sea): The submarine eruption continues. A small steam plume continued to rise from the new eruption site this morning and an SO2 plume hovers above the area.
