TW – June 16, 2018
A strong eruption took place from Sakurajima’s Minamidake crater volcano at 22:20 UTC on June 15, 2018 (07:20 JST, June 16).
The eruption sent ash up to 4.7 km (15 400 feet) above the crater (5.8 km (19 000 feet) above sea level) and produced several pyroclastic flows.
Ashfall was reported in the city of Kagoshima, capital of Kagoshima prefecture, located 8 km (5 miles) west of the volcano.
There were eight events and five explosions at Minamidake crater from June 4 to 11. Crater incandescence was occasionally visible at night. Ash plumes rose up to 2 km (1.2 miles) above the crater rim, except during an event at 11:35 JST on June 10 which produced a plume that rose 3.5 km (2.1 miles). Tephra was ejected as far as 1.3 km (0.8 miles) from the crater between June 8 and 11.

As scientists continue to tell the public not to worry, the largest geyser in Yellowstone has just gone off for the ninth time. Normally, this geyser is quiet for years at a time, but scientists are now saying this is the new normal.
Over the past few months, the Steamboat geyser has sprung to life and now seems to be erupting somewhat on a predictable schedule, at least for the moment. According to Forbes, just after 1 a.m. Monday it sent boiling water hundreds of feet into the air for the ninth time this year. Before this recent string of eruptions, Steamboat had been dormant since 2014. “Major eruptions over the past several weeks have been occurring with surprising regularity (every 6 to 8 days),” wrote Jamie Farrell, Chief Seismologist of the Yellowstone Volcano Observatory (YVO).
This news comes as the Kilauea volcano in Hawaii continues to erupt sending lava flows into the ocean and Guatemalan volcano erupted sent pyroclastic flows into a town killing at least 100 people. Are the world’s volcanoes waking up? Not if you ask scientists.

The Volcan de Fuego in Guatemala has erupted, shooting ash 10 km into the air and blanketing villages within 25km of the crater. Residents in the vicinity of the volcano have been advised to evacuate.
After awakening on Sunday, and for the second time this year, the Volcan de Fuego (Volcano of Fire) has generated strong pyroclastic flows in the Barrancas de Cenizas, Mineral, Seca, Taniluya, Las Lajas and Barranca Honda localities, the National Coordinator for Disaster Reduction in Guatemala (Conred) said.
After shooting up some 10,000 meters into the air, the residue “advanced more than 40 kilometers” with the direction of the wind, Conred said, noting that the eruption “generated strong reverberations with shock waves causing vibration in roofs and windows at a distance of 20 kilometers.”
There were no immediate reports of any casualties, but authorities are advising those close to the crater to evacuate the area. The International Airport La Aurora closed its runway due to the volcanic ash as a precautionary measure.

A major eruption took place at Mount Sinabung, Indonesia around 09:00 UTC on April 6, 2018 shooting ash up to 15 km (50 000 feet) above sea level. The Aviation Color Code was raised to Red. This is the second major eruption of this volcano within 2 months.
The eruption produced numerous pyroclastic flows, reaching 3.5 km (2 miles) to the east and southeast.
The Darwin VAAC reported two columns of volcanic ash. The first to 15 km (50 000 feet) moving NNE, and the second to 7.3 km (24 000 feet) moving SW.
Today’s eruption is comparable to a high impact eruption of February 19, 2018. At the time pyroclastic flows traveled 3.5 km (2.1 miles) and 4.9 km (3 miles) from the summit and ash plume reached an altitude of 16.7 km (55 000 feet) above sea level.

A powerful eruption took place at Mayon volcano, Philippines around 04:45 UTC on Monday, January 22, 2018 (12:45 local time), producing a column of ash that rose up to 7.6 km (25 000 feet) above sea level. At 05:10 UTC, the Tokyo VAAC reported ash cloud up to 12.5 km (41 000 feet) a.s.l. and corrected it within 30 minutes. Increased activity at the volcano forced authorities to raise the Alert Level from 3 to 4 (hazardous eruption imminent). The scale goes up to 5.
Heavy ashfall was reported in communities around the volcano and as far as Ligao City, some 35 km (21.7 miles) from Legazpi City. Albay Governor said zero visibility has been reported in parts of Guinobatan, Ligao, and Camalig after the major ash eruption, advising everyone to wear their face masks and to stay indoors, especially those in the 3rd district of Albay.
Classes in all public and private schools across the entire province have been suspended.
Volcanologist Ed Laguerta said the eruption lasted for some 8 minutes and generated pyroclastic flows towards Camalig and Guinobatan towns southwest of the volcano.

Guatemala’s Fuego volcano erupted at 13:15 UTC on May 5, 2017, producing pyroclastic flows and ejecting thick volcanic ash cloud to an estimated altitude of 5 km (16 405 feet) above sea level. INSIVUMEH is describing it as one of the strongest eruptions in recent years, recommending CONRED to raise the alert level to Orange.
In a special bulletin released 17:00 UTC on May 5, INSIVUMEH said volcanic ash cloud is moving more than 50 km (31 miles) to the south, southwest and west, generating ashfall in San Pedro Yepocapa, Morelia, Santa Sofía, El Porvenir, Palo Verde and others on this side, like Santa Lucia Cotzumalguapa, Siquinala, San Andres Osuna, Chuchu and La Reunión.
Ash is being produced by pyroclastic flows down the Trinidad, Las Lajas, Ceniza and Santa Teresa drainages.
This is the strongest eruption since 2012, INSIVUMEH said and added it forced the evacuation of the village of Sangre de Cristo (population 300), located on the west flank.
The agency warned that large quantities of volcanic material are being deposited, raising a threat of lahars in the coming days.
Volcano Discovery – November 1, 2016
The eruption of the volcano continues, but has again entered a phase of increased activity since a few days ago: a new lava lobe, which has been growing since around 20 October, is now being destroyed by an ongoing series of frequent small to moderate pyroclastic flows that affect the southeastern and eastern slopes.
At the same time, the volcano has been producing sometimes comparably strong vertical explosions. This suggests that the internal supply of fresh and gas-rich magma is currently elevated (compared to the average of the past months when the volcano was mostly calmer.
During a 6 hours interval this afternoon, the volcano observatory reported one explosion and 7 pyroclastic flows on the east-southeastern flank with run-out lengths of 1500-3500 m, and associated ash plumes rising 800-1500 m high. The larger of the pyroclastic flows are coming dangerously close to, and again threatening areas which have still been being used and visited by local farmers and others (despite being well inside the official exclusion zone). It can only be hoped that no new accidents occur.
Rhaydz B. Barcia – September 08, 2016
LEGAZPI CITY, Philippines – The Philippine Institute of Volcanology and Seismology (Phivolcs) has warned of a possible “big” Mayon volcano eruption in the coming days.
“Phreatic explosion may happen anytime but a big explosion is expected in the coming days,” said Philvolcs resident volcanologist Eduardo Laguerta.
Laguerta cited “abnormal activity” similar to what happened prior to the Mayon eruption in 1984.
The 1984 Mayon eruption is classified as a Vulcanian-type eruption which involves relatively small but violent explosions of thick lava producing columns of ash, gas, and occasional pyroclastic flows.
