Sakurajima (Kyushu, Japan): (22 Jun) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTED AT 20180622/0538Z FL070 STNR OBS VA DTG:22/0530Z
Sinabung (Sumatra, Indonesia): (22 Jun) Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: GROUND REPORT OF VA TO FL120 OBS VA DTG:22/0223Z
Krakatau (Sunda Strait, Indonesia): (22 Jun) It seems that the volcano is indeed heading into a new eruptive phase. Another explosion occurred at Krakatau this morning, as our expedition organizer Andi reported (see attached picture).
Dukono (Halmahera): (22 Jun) Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: CONTINUOUS EMISSION TO FL070 EXT TO W EST VA DTG:22/0600Z
Aoba (Vanuatu): (22 Jun) Volcanic Ash Advisory Center Wellington (VAAC) issued the following report: LOW LEVEL ERUPTION CEASED.
Mauna Loa (Big Island, Hawai'i): (22 Jun) Volcanic unrest at the volcano has ceased (at least for now), and the volcano observatory lowered the alert level of the volcano back to "normal" (green):
"HVO seismic and deformation monitoring networks have been recording near background levels of seismicity and ground motion at Mauna Loa Volcano for at least the last six months. These observations indicate that the volcano is no longer at an elevated level of activity. Accordingly, HVO is dropping the Mauna Loa alert level to NORMAL and the aviation color code to GREEN."
Kilauea (Hawai'i): Kilauea’s summit continues to steadily subside in response to the large volume of magma that was drained from beneath the caldera towards the lower East Rift Zone early May. This process is most pronounced around Halema’uma’u crater whose walls are falling in on itself and by now has grown to nearly twice its original width and depth – having partially swallowed the old overlook parking lot. What was once a 12-acre (0,05 square km) lava lake in the middle of the crater has grown to more than 130 acres (0.526 square km), at places up to 300 m (1000 ft) deep, and is getting larger every single day. A preliminary estimate of summit volume loss is around 260 million cubic meters as of June 15th, 2018.
This slow but steady slumping of Halema’uma’u has given rise to a remarkable seismic pattern that has been established since the end of May and persists to this day. Over a time span of ca 20- 28 hour periods, lower seismicity (about 10 earthquakes an hour) quickly changes to more intense seismic activity (up to 35 earthquakes an hour) as pressure builds up deep inside the vent. Eventually this pressure built-up culminates in a gas driven explosion and seismic event larger than magnitude 5, creating a gas and ash plume that rises about 305 meter (1000 feet) before it quickly dissipates. These stronger events may thereby trigger partial collapses of the unstable rim of Halema’uma’u crater.

Telica (Nicaragua): Telica volcano in Nicaragua had a small eruption on Thursday morning 21 June 2018. The Nicaraguan Institute of Territorial Studies (Ineter) reports that the explosion expelled abundant gases, ash, sand and some rocks as well as an eruption column that rose to 500 meters above the crater rim before moving to the east and south – southwest. The fragments of ejected rocks fell near the crater whereas some sandy material and ashes reached the communities Los Manglares, Las Marías, Pozo Viejo, El Porvenir and Monte de los Olivos.
After this explosion the volcano continued to emitting gases, but Ineter stated that this is part of the normal activity of an active volcano such as the Telica and that for the moment this type of activity does not represent a danger for the population. Last March there was a seismic swarm recorded around Telica volcano of magnitude 2.1 to 2.8 at depths between one and six kilometers, followed by periods with weak ash emissions and night-time glow in early April and May.
