Sheveluch, Kamchatka :


Lava descending from the Shiveluch volcano in Russia’s Far East has raised columns of ash up to five kilometers above the sea level, scientists from the Kamchatka Volcanic Eruption Response Team (KVERT) told TASS on Monday.
« The volcano continues erupting. Lava has descended today from the top of the Young Shiveluch. Columns of ash were raised up to five kilometers above the sea level, » scientists said adding that there is no threat to settlements in the area.



The ash cloud is drifting to the east and south-east, with the plume covering the area of around 15 kilometers.
The Russian Emergencies Ministry’s department in the Kamchatka region said that no ash falls were reported in the area.
An orange alert was issued over the eruption of the Shiveluch which can spew ash up to 10 kilometers above the sea level at any moment. Airlines that fly near the Shiveluch are recommended to change their routes. There are over 150 volcanos on the Kamchatka peninsula in Russia’s Far East, and up to 30 of them are active.

The Shiveluch is located some 450 kilometers (280 miles) to the north-east of the Kamchatka Peninsula’s largest city of Petropavlovsk-Kamchhatsky with the population of over 181,600 people. However, nearest residential areas are located within the distance of 50 kilometers (31 miles) from the Shiveluch, which had been regularly spewing out ash since 1980s.

Bárðarbunga , Iceland  :


A few earthquakes were observed in the caldera of the night. The largest measured 3.5 on the Richter scale, at 02:23. Then there was another tremor a few minutes later, at 02:27. The rate was 3.1 points. This comes out in the Notice from IMO.

There has been inflation in the area around the Bárðarbunga caldera in recent months, fueling a dynamic collection of the caldera. Having evidence of this has been increasingly evident. Such expansion, however, is said to be common in the vicinity of the volcano after the eruption.



 The large central volcano of Bárdarbunga lies beneath the NW part of the Vatnajökull icecap, NW of Grímsvötn volcano, and contains a subglacial 700-m-deep caldera. Related fissure systems include the Veidivötn and Trollagigar fissures, which extend about 100 km SW to near Torfajökull volcano and 50 km NE to near Askja volcano, respectively. Voluminous fissure eruptions, including one at Thjorsarhraun, which produced the largest known Holocene lava flow on Earth with a volume of more than 21 cu km, have occurred throughout the Holocene into historical time from the Veidivötn fissure system. The last major eruption of Veidivötn, in 1477, also produced a large tephra deposit. The subglacial Loki-Fögrufjöll volcanic system located SW of Bárdarbunga volcano is also part of the Bárdarbunga volcanic system and contains two subglacial ridges extending from the largely subglacial Hamarinn central volcano; the Loki ridge trends to the NE and the Fögrufjöll ridge to the SW. Jökulhlaups (glacier-outburst floods) from eruptions at Bárdarbunga potentially affect drainages in all directions.

Kanlaon, Philippines :

Kanlaon Volcano’s seismic monitoring network recorded five (5) volcanic earthquakes during the past 24 hours. Steaming activity could not be observed due to thick clouds covering the summit.



Alert Level 1 status remains in effect over Kanlaon Volcano, which means that it is at an abnormal condition and is in a period of current unrest. The local government units and the public are reminded that entry into the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to the further possibilities of sudden and hazardous steam-driven or phreatic eruptions. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as airborne ash from a sudden eruption can be hazardous to aircraft. DOST-PHIVOLCS is closely monitoring Kanlaon Volcano’s activity and any new development will be relayed to all concerned.
