Eruption news from Cleveland volcano:
Cleveland volcano (Alaska): new eruption
Thursday Jun 18, 2015 10:51 AM | BY: T
The Alaska Volcano Observatory detected that a new (so far minor) eruptive episode has started at the volcano recently:
"Elevated surface temperatures have been detected in satellite images at the summit of Cleveland for the past week, and an image from June 14 shows very light ash cover on the volcano's upper flanks. Thus the volcano has entered a renewed period of unrest and we are raising the Color Code to Yellow and the Alert Level to Advisory.
The increase in temperature at the summit is consistent with renewed growth of the small lava dome within the summit crater. The possibility of sudden explosions has increased." (AVO)
Cleveland volcano (Alaska): small explosions in early June
Wednesday Jul 02, 2014 12:05 PM | BY: T
AVO reported earlier in June that an explosion from Cleveland on the evening of 5 June was detected on the Dillingham acoutstic infrasound array and at seismic stations at Korovin volcano. The brief event was similar to previous explosions at Cleveland, and generated a small detached plume with a weak ash signal observed in satellite imagery.
The cloud was at an altitude of about 7.6 km (25,000 ft) a.s.l., had moved about 140 km SW, and rapidly dissipated. The last previous explosion at was 6 March, seen by residents of Nikolski who reported small ash puffs.
Volcanoes Today, 16 Jun 2015: Semeru volcano, Bulusan, Sinabung, Asama
Tuesday Jun 16, 2015 09:00 AM |
Asama (Honshu): A small eruption occurred at the volcano this morning around 9am local time.
The Japanese Meteorological Agency (JMA) confirmed light ash fall occurred in 4 km north of the volcano. A short phase of increased seismic activity preceded and accompanied the explosion. According to a news article, JMA scientists think that today's explosion will likely be followed by similar ones in the near future, but not lead to a larger scale eruption.
There are no clear signs (such as deformation) of a major body of fresh magma is rising under the volcano. In that case, a possible scenario is that the eruption this morning is mostly phreatic in origin, i.e. driven by overheated ground water with no or little involvement of new magma.
Bulusan (Luzon Island, Philippines): Two small steam-driven (i.e. phreatic) explosions occurred at the volcano this morning at 11:02 and 11:20 local time, PHILVOLCS reported.
The first lasted 2 minutes and generated a steam and ash plume that rose 1 km and drifted WSW. Rumbling sounds were heard in the villages of Cogon and Irosin on the WSW slopes.

Alert level 1 (abnormal) remains in effect over Bulusan Volcano and a 4 km exclusion zone is in effect.
Sinabung (Sumatra, Indonesia): Pyroclastic flows continue to threaten the southeastern and east-northeastern slopes of the volcano.
According to a news article, approx. 1,200 people were evacuated yesterday, bringing the total number of current refugees to almost 4,000. Another 2,500 residents should be evacuated over the next few days.
Semeru (East Java, Indonesia): Japa's highest volcano has resumed its typical, intermittent ash-righ explosions.
Our friend Aris Yanto climbed the volcano on 11 June and shared the attached picture on his facebook page.

Saturday Jun 06, 2015 22:00 PM |
Dukono (Halmahera): (6 Jun) Strong ash emissions continue from the volcano. Based on satellite data, VAAC Darwin reported that ash plume rose to 8,000 ft (2.4 km) altitude and extended 70 km NW this morning.
Sunset Crater (Arizona): Recent rumors about steaming from Sunset crater, and speculation of a possible reawakening of the volcano are most likely based on false or fake information. The volcano, one of Arziona's youngest, last erupted about 1000 years ago, but shows currently no signs of reawakening.
Of course, future eruptions are an entirely possible scenario - however, there's no indication this is about to occur right now.
Fuego (Guatemala): (6 Jun) Another strong eruptive phase with the effusion of lava flows and elevated explosive activity has been occurring at the volcano since yesterday.
Two active lava flows are descending the Cenizas and Trinidad ravines on the SSW and S sides of the volcano. Strombolian explosions create a steam and ash plume that rises to approx. 5 km altitude and drifts 15 km W and NW.
Barren Island (Indian Ocean): (6 Jun) A steam and ash plume at estimated 10,000 ft (3 km) altitude and extending 35 km to the east from the volcano was detected yesterday on MTSAT satellite imagery (VAAC Darwin).
A moderately strong hot spot is visible at the volcano as well, suggesting that the eruptive phase that had started in April might still be going on at a low level.
Volcanic activity worldwide 5 Jun 2015: Bagana volcano
Friday Jun 05, 2015 22:00 PM |
Bagana (Bougainville Island, Papua New Guinea): (5 Jun) Based on satellite observations, the volcano has produced a number of ash plumes rising to approx. 8,000 ft (2.4 km) altitude, which drifted 40 km to the west. (VAAC Darwin)
A strong heat source has been visible at the crater since 21 May as well. This suggests a new eruptive phase is in course, likely in form of a lava dome extrusion and/or mild strombolian activity.
Volcanic activity worldwide 4 Jun 2015: Colima volcano
Thursday Jun 04, 2015 22:00 PM |
Colima (Western Mexico): (3 Jun) Explosions of various sizes continue to occur from the volcano's summit vent. A particularly spectacular one this morning around 06:10 local time showered the summit cone with incandescent material and triggered small pyroclastic flows:

Volcanic activity worldwide 3 Jun 2015: Sinabung volcano, Cotopaxi, Ambrym
Wednesday Jun 03, 2015 20:01 PM |
Sinabung (Sumatra, Indonesia): The alert level of the volcano was again raised from "siaga" to "awas", the highest on the Indonesian 1-4 scale. The reason is a currently elevated risk of possibly larger pyroclastic flows, that could be triggered by collapse of the increasing volume of the viscous lava lobe emplaced on the upper SE flank.
The alert level of the volcano had been at 4 during late Nov 2013 until April 2014,- the first and so far most violent phase of pyroclastic flow generation after the lava had spilled over the summit crater and built a large lobe that reached the base of the cone.

Since then, for more than a year now, lava effusion has continued at mild, more or less constant rate. Tremor data suggest that the supply rate of magma to the volcano's summit has been more or less constant during the past year.
This activity produced successive lava lobes on the upper flank, all on top and/or at the upper sides of the main flow emplaced during the first months of the eruption. Associated avalanches and pyroclastic flows had mostly been smaller in comparison, although a few larger ones occurred as well.
Ambrym (Vanuatu): (3 Jun) The lava lakes on Ambrym remain very active.
As to visiting the island and the aftermath of Cyclone Pam, our partners on location (guides, porters etc) confirmed us that expeditions to Ambrym and Vanuatu in general can again run with no obstacles. Have a look at our volcano tour!
Cotopaxi (Ecuador): (3 Jun) The volcano has been showing signs of unrest. Since mid-April this year, and particularly during May, a marked increased in earthquakes and SO2 emissions have been detected, which could be signs of a magma intrusion beneath the volcano.
During May, about 3000 local earthquakes were recorded, a significant increased compared to April (628 quakes), and more than during the last seismic crisis in 2001-02.
Volcanic activity worldwide 2 Jun 2015: Pacaya volcano, Fuego, Dukono, Piton de la Fournaise, Gualla...
Tuesday Jun 02, 2015 17:23 PM |
Kuchinoerabu-jima (Ryukyu Islands): An analysis of the erupted ash from 29 May confirms that the explosion was, as suspected, phreatomagmatic in origin, i.e. driven by the presence of new magma interacting with external water.
The ash samples contained about 30% juvenile (fresh) lava fragments, while the rest were mostly altered older rocks. The ratio of fresh magma involved in the eruption has increased compared to the eruption last year on 3 August.
Dukono (Halmahera): An ash plume reaching approx. 10,000 ft (3 km) altitude and extending more than 100 km to the NW was visible on satellite imagery this morning (VAAC Darwin).
Wolf (Galápagos Islands, Ecuador): While no direct confirmation has been available from ground observations since 30 May, it seems plausible to assume, from satellite observations, that the eruption still continues and that the lava flow on the southeast flank of Wolf is still active and its front reaches near or into the sea.
The latest satellite-based imagery still show high SO2 emissions and a strong thermal anomaly in the area.

Pacaya (Guatemala): INSIVUMEH reported degassing and occasional ash emissions that rise approx. 200 m above the Mackenney crater. This is likely a sign of weak, dee-seated strombolian activity from a vent inside the crater.
Fuego (Guatemala): Activity remains relatively intense, with frequent strombolian-type explosions ranging from small to strong, according to the volcano observatory. Incandescent material is ejected up to 150 m above the crater and ash plumes rise up to 1 km.
Most explosions are accompanied by shock waves that rattle windows and doors in nearby villages.
Guallatiri (Northern Chile, Bolivia and Argentina): Elevated seismic activity since the night 30-31 May triggered SERNAGEOMIN to raise the alert level of the volcano to "yellow".
A swarm 22 earthquakes related to internal rock fracturing, possibly caused by rising magma, was registered shortly after midnight 30-31 May. A magnitude 3.7 quake occurred at 05:17 local time the next morning.
At the same time, slight deformation of the summit area of the volcano was detected as well, which would be consistent with a new magma intrusion at depth. No other changes (such as increased degassing, rock falls etc) have been noted.
This information came from http://www.volcanodiscovery.com and you are welcome to look it up yourself. There are more volcanoes active than is normal at the moment. The Ring of Fire, which is a circle around the rim of the Pacific Ocean, has awakened violently.
