February 2, 2015 - EARTH - The following constitutes the new activity, unrest and ongoing reports of volcanoes across the globe.
Etna (Sicily, Italy): The new eruptive phase continues. Dense cloud cover has prevented detailed observations, but from occasional clearings and other observations, it seems that the intense strombolian eruptions are going on from a vent between the old and New SE crater, feeding a lava flow, at least 2.5 km long onto the southwestern slope.
Tremor remains high.
More details start to emerge about the new eruptive phase. Strombolian activity from the SE crater accompanies important lava effusion, feeding an impressive lava flow.
The lava flow has been taking a path to the SW, passing the 2002 cones on their western side and descending already to approx. 2000 m or less altitude, a few km west of the provincial road to La Sapienza.
Shiveluch (Kamchatka): A powerful explosion occurred this morning, at 02:08 local time, at the volcano. It seems a large-volume pyroclastic flow of several km length and an ash plume rising to approx. 33,000 ft (10 km) altitude were generated.
The eruption occurred from the same area of the active lava dome as the ones during the past weeks, i.e. from the north side of the dome's cone near the 1964 caldera wall.
Kilauea (Hawai'i): Some images of frozen and active pahoehoe lava taken during an excursion to active lava flows from Kiilauea during one of the recent Round-The-World tours.
The June 27th lava flow remains active, but its advance is slow. The leading edge is currently stalled roughly 500 meters from Highway 130 at Pahoa.
Breakouts remain active a short distance upslope of the leading tip of the flow, and continue to slowly widen the flow.
Bardarbunga (Central Iceland): A small earthquake swarm at 1 km below the eastern rim of the Bardarbunga caldera occurred yesterday evening at 21:22 local time, accompanied by a rise in tremor.
John Friman who closely follows the events in Iceland suspects on his blog that a minor subglacial eruption could have taken place.
If so, a meltwater flood should be expected in the course of the day.
The visible intensity of the eruption continues to decrease gradually last week. The Icelandic Met office conducted air-borne measurements of the lava field last week, showing that it has significantly thickened (rather than expanded laterally) during the past weeks, and is now estimated to contain approx. 1.4 cubic kilometers of lava. Effusion rates, although decreasing, are still close to an impressive 100 m³ per second.
Kliuchevskoi (Kamchatka): The volcano's activity today consisted of continuing mild to moderate strombolian activity. Probably the lava flow on its upper flank is still active, but seems to have decreased. Frequent incandescent avalanches occurred, accompanied by mild ash emissions.
VAAC Tokyo issued a warning about a possible ash plume rising to 34,000 ft (10 km) altitude at 02:57 UTC, although it stated that no ash was visible on satellite imagery, and no such plume is visible on webcam imagery, only a rather diluted ash plume at much lower altitude.
Hunga Tonga-Hunga Ha'apai (Tonga, Tonga Islands): An exceptional satellite image taken by the European Pléiades satellite from 19 January 19 shows the new island that formed during the eruption near Hunga Ha’apai island (left in images) earlier this month and joined it by forming a new peninsula, composed of a broad, flat ash cone with a water-filled crater.
The image also shows that activity seems to have already stopped by the 19th when the image was taken. Most likely, the new land addition will be eroded within months, because it seems mainly to be composed of loose materials, as opposed to more resistant solid lava flows.
What makes this remarkable news, however, is that we don’t get the chance to see this kind of wild geology in action on a day to day basis.
In fact, most islands today are made from underwater volcano eruptions. The story of a volcanic island starts inside the Earth. Earth has a solid inner core. It’s made of solid metal. It is thought to be as hot as the surface of the sun! A liquid outer core surrounds the inner core. The outer core is made of metals, too. It is liquid because it is under less pressure than the inner core. Around the outer core is the Earth’s mantle. It’s made of hot rock called magma. It’s mostly solid, but it can flow like hot plastic. We live on the crust. It is the thin, outside layer of the Earth. The crust is in pieces like a jigsaw puzzle. They are called tectonic plates. The plates fit together. Forces caused by Earth’s heat sometimes push them tighter against each other. Sometimes forces pull them apart. Sometimes there are weak spots in the crust. When plates pull apart or there is a weak spot, the mantle’s hot, flowing magma oozes out.
Fogo (Cape Verde): The eruption still continues although most of the time visible activity is very low and restricted to degassing. Minor lava effusion and sporadic flares of strombolian activity of mild to moderate size occur from time to time.
Scientists from the Cabo Verde volcano observatory (OVCV) who climbed the volcano on 25 January observed small ash emissions, and published a detailed report about the most recent significant activity during 20-23 January, when explosions produced a short-lived ash plume that rose up to 1200 meters on the morning of 20 Jan, as well as a small lava flow on the following day.
Karymsky (Kamchatka): Moderate explosive activity continues. Ash plumes from strombolian to vulcanian eruptions were reported by KVERT, reaching approx. 14,000 ft (4.2 km) altitude and drifting north and later east from the volcano. Aviation color code remains "orange".
Shishaldin (United States, Aleutian Islands): A faint thermal signal remains visible on satellite imagery. According to the Alaska Volcano Observatory, weak eruptive activity likely continues in the summit crater.
San Miguel (El Salvador): A small explosion occurred last Monday at 06:43 morning. Probably phreatic in nature, it was the first eruptive activity since minor ash emissions past July.
According to MARN, falling blocks from the eruption could be heard from people in the vicinity of the volcano. No further eruptions have followed so far, and no significant temperature signal can be detected at the summit, only constant degassing reaching 150-250 m height.
Seismic activity remains relatively low, but sudden explosions of small to moderate size remain a possibility.
Sangay (Ecuador): Eruptive activity of some sort is likely in progress at the volcano. Along with pilot reports of spotted plumes relayed through the Washington VAAC, thermal signals detectable on satellite data have been more and more frequent since early January, Culture Volcan points out in his blog.
It is unknown what kind of activity is occurring, but the most likely scenario is mild to moderate strombolian activity, which is typical for Sangay,- an extremely remote, but at the same time very active, that often has this type of activity. In many ways it is similar to its Kamchatka counterpart Klyuchevskoy currently in eruption as well.
