Fagradalsfjall (Reykjanes Peninsula, Iceland): The eruption goes on with little changes overall, but lava effusion rate has increased to approx. 12.4 cubic meters per second. The activity, however, has remained almost entirely effusive with no more lava fountains from the vents during the past 24 hours.
Most of the time, the erupted magma is going directly into lava tubes, but occasionally, surges of lava also erupt as flows from the rim of the main vent, producing surface flows nearby.
Tremor also increased to higher levels, reflecting the increase in effusion rate.

Suwanose-jima (Ryukyu Islands): (3 Jun) A series of strong vulcaninan-type explosions occurred from the volcano over the past week. The activity of the volcano is characterized by strong ash emissions from the summit Ontake crater.
The Japan Meteorological Agency (JMA) and Volcanic Ash Advisory Center Tokyo (VAAC) reported about dense dark ash plumes which reached approx. 7,000 ft (2,100 m) altitude and were dispersed about 4 km to south-southwest of the volcano.

Loihi (United States, Hawaiian Islands): Seismic instruments of the Hawaiian Volcano Observatory (HVO) detected a volcano-tectonic earthquake with magnitude M 4 at 11 km depth beneath the Lō'ihi seamount at 18:44 local time yesterday.
Moderate shaking, with maximum Intensity of V on the Modified Mercalli Intensity Scale, has been reported across the Island of Hawai'i. At that intensity, significant damage to buildings or structures is not expected.

Nyiragongo (DRCongo): Seismic activity continues to decline, with small quakes (not felt) being detected south of the volcano and under Lake Kivu. Similarly, GPS- and satellite-based measures of ground deformation also show a decreasing trend.
This is good news for Goma and its surroundings: the likelihood of a new eruption in the near future continues to decrease, although vigilance remains high.
