Grímsvötn (Iceland): (17 Jun) One of Iceland's most active volcanoes might be getting ready for a new eruption. Recent observations by scientists from the Icelandic Met Office (IMO) monitoring the sub-glacial volcano lead to this conclusion, IMO reported in a recent press release.

In the last weeks, several measurements were done at Grimsvötn volcano. They discovered a currently very high output of SO2 gas in the southwest corner of the caldera in Grimsvötn, very close to the eruption sites of 2004 and 2011, a clearly alarming finding: "This is the first time that we measure so much SO2 at a volcano in Iceland that is not in an eruptive phase and its presence is indicative of magma at shallow level", said volcanologist Melissa Anne Pfeffer from the IMO who was among the specialist during the recent measurements. In the area where geothermal activity of the volcano can be detected at the surface, this has also notably increased.

Reykjanes (Reykjanes peninsula (SW Iceland)): (17 Jun) The Icelandic Met Office (IMO) reported that in mid-May deformation data (GPS and InSAR measurements) started to show again signs of inflation, suggesting that a third intrusion since the beginning of this year is occurring west of Thorbjörn. The intrusion began around mid of May but the seismic activity started to increase toward the end of the month (30 May). About 2000 earthquakes have been detected since then and several events are located East of Thorbjörn, few kilometers North of the town of Grindavík. The largest earthquake of this swarm occurred on 13 June with magnitude M 3.5.
Since the beginning of the volcanic unrest, in January this year, the total uplift measured in the area is assessed to be around 12 cm. Between the inflation periods, slight deflation has been observed, probably reflecting the cooling of the intruded magma or the interaction with the geothermal system. Numerical modelling results show that this third intrusion is occurring roughly in the same area as the previous ones, i.e. at about 1 km West of Thorbjörn, at a depth of 3-4 km, with a width of few hundreds of meters and oriented NE-SW for about 6 km.

Dukono (Halmahera): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 7000 ft (2100 m) altitude or flight level 070 and is moving at 10 kts in NW direction.
The full report is as follows: CONTINUOUS VA TO FL070 OBS AT 17/1750Z OBS VA DTG:17/1845Z to 7000 ft (2100 m)
Volcanic Ash Advisory Center (VAAC) Darwin reported that an explosion occurred at 15:45 local time today.
Emissions of gas, steam and white-gray ash from the active crater reached approx. 7,000 ft (2,100 m) altitude. Volcanic ash is dispersed towards the northwest and causes ash fall onto the volcano's slopes.

Pacaya (Guatemala): (17 Jun) INSIVUMEH reported that three lava flows continue to be observed from Mackenney summit crater. Two lava flows continue to be active on the north slopes of the volcano and one lava flow continues to be active on the west flank.
Glowing lava spatter is being ejected to an approximate height of 25 to 50 meters above the crater.
