VONA/KVERT DAILY REPORT
Kamchatkan and Northern Kuriles Volcanic Activity
April 04, 2013, all time is UTC
PLOSKY TOLBACHIK VOLCANO (CAVW #1000-24-)
55.83 N, 160.39 E; Elevation 10119 ft (3085 m)
Aviation Color Code is ORANGE
Strong seismicity of the volcano was registered. An amplitude of volcanic tremor was up to 4.1 mcm/s. Explosive-effusive eruption continues: lava flows continues to effusing from the Southern fissure on Tolbachinsky Dol. Incandescence of the lava flow deposits, and strong gas-steam activity accompany this process. A big thermal anomaly was noting on satellite images at the northern area of Tolbachinsky Dol.

Survey of Tolbachik eruption

31/03/13 5:47 evacuated tourists Tolud
Today, at about 13:00 local time, with a strong westerly wind, with field base Tolud shot foreign tourists and took them to Esso.
On Tolbachik in breakthrough were two other photographers. They refused to take off. Sit there for two weeks.


03.04.13 18:03
On Tolbachik could fly only the third attempt. First helicopter broke, then thick clouds prevented to land and only 1 April hardly abandoned.
Caught in a cyclone - all day on April 2, it was snowing and the wind was blowing. We were hooked another helicopter from Petropavlovsk-Kamchatsky, but was unable to fly back - closed clouds. We spent the night without sleeping flown at -20 C. But in the morning, April 3, was gorgeous weather, and that's working. But for us at 9:00 flew a helicopter.
Despite the tight deadlines and difficult weather conditions the job done.
In the windows above the lava flow managed to select the volcanic gases. Geologists have fresh samples from lava flows. Evaluated the lava flow on the stream width of about 10-15 m and velocity - about - 3 m / s, to a depth of 3 m - it was in the range of 60 to 100 m3/sec.
This is associated with increased activity of the eruption in the last 2 days.
Photo and video made its outflow of lava and the formation of its various forms. The main lava flows extend towards Tolud. One stream flows south to Lazo. At night you can watch the fantastic picture - all in flames

basing on yesterday's NASA say shot (no fresh) still can not say anything definite, we can only note some interesting details
[link to lance-modis.eosdis.nasa.gov]
firstly, relatevely stable cloud formations (fixed breaks) to the south-east of Grimsey . i.e. in area of shallow eqs and main swarm . sometimes such formations indicates underwater processes.
then, to the north from Grimsey, where no clouds, there is even a small but visible change in color of the ocean surface.
finally, to the east and south-east from swarm area visible cloud formations similar to the so-called "heralds" earthquake precursors. there is a formula to calculate the intensity of the coming earthquake in length like cloud formations (experienced seismologists forecast is confirmed by her quite well). in this case, the intensity and the area of these formations is small, so if trust in this predictor in the TFZ very strong earthquakes in the future is not expected (though IMO seems to be a different opinion - they write on their website that it is possible the continuation of strong shocks and spread to the south-east)

experts are silent or in dreams... then why not continue

tnen now a little bit fearmongering (very little)
exactly the same as just one drop of sauce can greatly improve the taste of food served, as well as serious and scientifically based information from time to time are useful to mix with small additions of fantasies - science without imaginations would not have moved forward at all

after yesterday (want-believe it, want - no that it was actually after)
i asked here question about very unusual sounds of last Etna eruption (above)
i read
[link to www.wired.com]
Another day, another paroxysm at Etna. This one was quite spectacular event in the new Southeast Crater — Dr. Boris Behncke captured some of the splendid lava fountaining from this eruption. Interestingly, he noted that the most impressive feature of this paroxysm, the 34th since the start of 2011, was the sound

and was even a little shocked at how much in the same direction seems we think about...

meanwhile, anyone noticed how the tremor pattern changed after the eruption ?

remember Surtsey?

Update 10:49 UTC : We have added a Google Earth screenshot to the image series. This Google earth image shows very clearly the many volcanic bubbles at the ocean floor, a result of the separating diverging plates. [link to earthquake-report.com]


so here's will refrain from forecasts

#Earthquake swarm in northern #Iceland

possibly caused by undersea eruption.


a very high degree of probability that this is so,
and not only he thinks about it

without going into unnecessary detail (3D, 4D)
really many signs of a high probability that the underwater eruption begins or even already started
(it should search on the Icelandic site articles of local experts).
just look at the number and distribution of aftershocks is very shallow, if only today

The research vessel Ramon Margalef, the Spanish Institute of Oceanography, returns to the island of longitude for the project VULCANO, an intensive sampling physicochemical and biological-geological around the entire periphery of El Hierro...
<Bob>
...Abnormalities on the underwater volcano
...The researchers report that the submarine volcano continues to record anomalous physicochemical parameters, as noted during the campaign of the Spanish Institute of Oceanography RAPROCAN in December 2012, but now, the anomalies are much higher and also there is a significant increase linked water temperature at the bottom of up to 3 degrees. The measured pH was 7.4, which represents an acidification of 0.5 points compared to normal conditions. Salinity, alkalinity and total inorganic carbon also exhibit high values relative to normal. However, in no case was detected significant concentrations of reduced sulfur compounds. In the absence of a definitive analysis, zooplankton communities have values of abundance and biomass relatively normal...
VULCANO now heads towards the northwest of the island of El Hierro, the epicenter of recent earthquakes with magnitudes of up to 4.9 on the Richter scale, where studies continue with the water column.

funny typo, probably Claude Grandpey at the same time preparing comments on El Hierro)

someone thought what means so many shallow earthquakes in the TFZ ?
[link to en.vedur.is]
which have "low quality" in above table?
ok, where close glacier it's relatevely clear .
but when such shocks with unclear location and unclear depth fixed at the bottom of the sea?
very worth reflecting

Volcano Type: Stratovolcano
Volcano Status: Historical
Last Known Eruption: 1967 ± 20 years
Summit Elevation: 2850 m 9,350 feet
Latitude: 8.25°S 8°15'0"S
Longitude: 118.00°E 118°0'0"E

The massive Tambora stratovolcano forms the entire 60-km-wide Sanggar Peninsula on northern Sumbawa Island. The largely trachybasaltic-to-trachyandesitic volcano grew to about 4000 m elevation before forming a caldera more than 43,000 years ago. Late-Pleistocene lava flows largely filled the early caldera, after which activity changed to dominantly explosive eruptions during the early Holocene. Tambora was the source of history's largest explosive eruption, in April 1815. Pyroclastic flows reached the sea on all sides of the peninsula, and heavy tephra fall devastated croplands, causing an estimated 60,000 fatalities. The eruption of an estimated more than 150 cu km of tephra formed a 6-km-wide, 1250-m-deep caldera and produced global climatic effects. Minor lava domes and flows have been extruded on the caldera floor at Tambora during the 19th and 20th centuries.

Based on the results of visual and seismic data analysis so as of 5 April 2013, at 19:00 pm, G. Status Tambora was raised from Normal (level I) to alert (level II).
