Zhupanovsky , Kamchatka :

Zhupanovsky Volcano in Russia’s Far Eastern Kamchatka Territory has spewed ash to a height of six kilometres above sea level, the Kamchatka Volcanic Eruption Response Team (KVERT) of the Institute of Volcanology of the Russian Academy of Sciences told TASS on Tuesday.

“The ash column reached six kilometres above sea level. The plume of ash has been taken by the wind to a distance of 30 kilometres in the southerly direction,” a KVERT spokesman said.

The volcano poses no threat to populated localities. Nonetheless, it has been assigned an orange aviation colour code. It is not ruled out that the volcano may spew more ash up to eight kilometres high.

Zhupanovsky

Zhupanovsky Volcano, which takes its name from a river of the same name flowing in its vicinity, is located in eastern Kamchatka, some 70 kilometers north of the Kamchatka capital, Petropavlovsk-Kamchatsky. Zhupanovsky is one of the least studied volcanoes in the region despite its proximity to a large city. It is a complex volcano composed of four overlapping cones aligned on a roughly east-west oriented axis, with the highest cone reaching 2,958 meters high, and the lowest one being 2,505 meters high. The giant mount has been active since October 2013.

June 8, 2015, SUMMARY OF THE ACTIVITIES OF VOLCANO

The volcano remains with moderate activity. During the afternoon of yesterday and today, briefly, a continuous emission of steam, with a low ash content, towards the southwest was observed.

Seismicity: 30 long period events (LP), 19 explosions, 14 episodes of tremor emission and harmonic tremor episodes were recorded.

Observations, emissions and ash:
In the afternoon of yesterday a continuous emission of steam with low ash content of approximately 500m to the south west, was observed. Also that day, at times, due to the cloud cover in the region.

Rains and lahars: Light rains were reported in the early hours of today, which did not generate lahars.

TAAL VOLCANO BULLETIN 9 June 2015 8:00 A.M.

Taal Volcano’s seismic network recorded seven (7) volcanic earthquakes during the past 24 hours. Field measurements conducted on June 04, 2015 at the western sector of the Main Crater Lake noted a slight increase in water temperature from 33.0°C to 33.4°C, a decrease in water level from 0.35 to 0.30 meter, and a slight decrease in acidity from pH 3.03 to 3.10.

Ground deformation measurements through precise leveling surveys on May 25 to June 3, 2015 indicated slight inflation of the edifice compared to Feb-March 2015. Ground deformation measurements from GPS data also indicate an inflationary trend since May 2014, with the edifice being slightly inflated compared to February 2011 baseline data. Carbon dioxide (CO2) emission at the Main Crater Lake decreased from 1980 tonnes/day in January 2015 to 1634 tonnes/day in April 2015.
Alert Level 1 remains in effect over Taal Volcano.

Weekly Report for the Period 29 May to 5 June 2015

Activity at the Soufrière Hills Volcano remains low.
The seismic network recorded one rockfall and five volcano-tectonic earthquakes this week.
Sulphur-dioxide measurements from six days during the reporting period gave an average flux of 432 tonnes/day with a maximum of 805 and a minimum of 208 tonnes/day.

Pyroclastic flows can occur at any time without warning on any side of the volcano, including Gages from where they can travel rapidly into Plymouth. Tracks across the Belham valley are frequently destroyed or heavily modified by flash flooding or lahars, and caution should be exercised crossing the valley during and after rainfall.

The Hazard Level is 1. There is no access to Plymouth or the rest of Zone V. Maritime Zones E and W are daytime transit only between sunrise and sunset (boats may sail through the zone but must not stop). Anyone who ignores these restrictions is liable to be prosecuted.
