Ebeko (Paramushir Island): (18 Jun) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20180618/0044Z FL090 EXTD SE REPORTED OBS VA DTG:18/0050Z

Sakurajima (Kyushu, Japan): On Saturday morning June 16, 2018, at 7h19 AM local time a strong explosion occurred from Sakurajima’s Minamidake crater. The eruption created an ash plume that rose about 4700 me above the crater and then drifted to the west. There were observations of pyroclastic flows running down the volcano’s southwest flank and significant ash falls were reported to cover Kagoshima. The volcano’s alert level is maintained at 3 – do not approach – since the start of its increased activity on February 5, 2016.
A video of the ash cloud rising after the explosion can be seen on the Facebook post below:


Mayon (Luzon Island, Philippines): (18 Jun) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: POSS ERUPTION OBS AT 20180618/0410Z FL180 EXTD SW OBS VA DTG:18/0430Z

Yasur (Tanna Island, Vanuatu): Volcanic Ash Advisory Center Wellington (VAAC) issued the following report: LOW-LEVEL ERUPTION CEASED.

Kilauea (Hawai'i): Volcanic Ash Advisory Center Washington (VAAC) issued the following report: SEISMIC EVENT AT 1614Z.
...18 Jun:
Kilauea’s summit caldera continues to subside in response to the withdrawal of magma from beneath the volcano’s summit that drains to the Lower East Rift Zone eruption site. The seismic cycle with M5 events and explosions in Halema’uama’u crater also persists, resulting in inward slumping of the crater rim and walls.
HVO/USGS report that during the night from 14 to 15 June seismicity increased once again to about 40 events per hour, including up to 5 magnitude-3+ earthquakes per hour, many of which were felt in the nearby village of Volcano. This gradual build up continued on June 15, 2018, and resulted in over 180 seismic events between 6 am and noon, 8 of which were stronger than magnitude-3.0. Finally an explosive event occurred at 11:56 AM that produced an ash and gas plume to nearly 3050 m (10,000 ft). This explosive event was captured by the Kilauea caldera live streaming camera and a video can be seen in the FB post below:

...18 Jun:
Throughout the weekend, Kilauea’s lower East Rift Zone eruption persisted to vigorously effusive large amounts of lava from fissure 8 which travelled along the well established 13 km (8 mile) channel to the broad ocean entry at Kapoho.
Fissure 8 continues to produce lava fountains with a pulsating height varying from 30 to 60 m (100 – 200 ft). This ongoing spattering of lava has built up an impressive cinder cone that partially encircles the fissure 8 vent and is now 51 m (170 ft) at its highest point. Lower fountains are thereby hidden from view within this cinder cone, but taller fountains are still adding fragments of lava (spatter) that continue to build the cone higher.

Fernandina (Galápagos Islands, Ecuador): After a short precursory period of seismic unrest, the volcano on Fernandino island, Galapagos, started a new eruptive phase on Saturday 16 June around 11h00 – 11h15 local time. A fissure on its NNE flank opened up with lava fountains that produced flows which quickly reached the sea.

Cerro la Cumbra volcano on Fernandino, the youngest island in the volcanic chain of the Galapagos, has entered a new eruptive phase. Saturday morning June 16, 2018, the Instituto Geofysico of Ecuador (IGPEN) reported a new seismic crisis only 9 months since the volcano’s last eruption. From 08h37 Galapagos Time (Ecuador Time -1 h) 9 earthquakes of magnitude higher than 2.5 were recorded. The largest earthquake was of magnitude 4.1 and occurred at 09h22 local at an estimated depth of 4 km. A few hours later the IGPEN confirmed that the volcano had started a new eruptive phase based on visual confirmation of boat passengers who reported their observations of lava flows reaching the sea at the Galapagos National Park.

IGPEN reports that the new eruption started on the north-northeast flank of the volcano and that based on photos and videos received at the Geophysical Institute it concerns a radial fissure eruption located on the NNE flank of the volcano. A number of lava fountains shoot up from the fissure and create lava flows that quickly reached the sea. The gas plume of about 2-3km height has only a low ash content but is extending more than 250 km to the west-northwest. IGPEN states that past eruptions of this volcano had durations from days to weeks, so they estimate a similar time frame for this eruptive phase. It should be noted that there are no human settlements in the area of the eruption and that the direction of the wind carries the gas to the west-northwest, contrary to the direction of the populated islands (Isabela, Santa Cruz, Floreana and San Cristobal). Recent satellite images also show a thermal anomaly on the volcano’s NNE flank. (IGPEN)
