Volcano and Earthquake watch

Ontake is still spitting ash etc, the number of bodies found is up to 48, according to the BBC. http://www.bbc.co.uk/news/world-asia-29440982

Volcán Calbuco in Chile is erupting after decades of dormancy. Evacuations underway.

This is one helluva photogenic eruption

 

[StoneRoad]

that's some eruption !

the daytime shot looks as if there are shock waves in the dust cloud.

Though the regional advisory centre hasn't issued a warning yet, several airlines are starting to avoid the area. An American Airlines flight from Dallas to Buenos Aires has just turned around mid flight (not yet confirmed if this is ash avoidance) and earlier an Air France from Charles de Gaulle to Buenos Aires diverted to Rio (confirmed as ash avoidance).

A longwave IR satellite image taken yesterday clearly illustrates the evolution of the hot ash cloud off towards the NE (which would be in the direction of Buenos Aires, eventually):

e2a: several more flights now confirmed diverted/returned for reasons of ash avoidance.
2e2a: A Qantas flight from Sydney to Santiago has also given up and returned to Sydney after several hours out over the Pacific.

Another image from the same satellite in the IR taken at night picking up airglow. In this you can see concentric rings of atmospheric gravity waves centred on the eruption (encircled in blue):

Buenos Aires indicated by the red arrow, Santiago by the green.

Nice time lapse of the eruption:

The ash cloud quite obvious from the space station within the last hour:

How about this for timing!

Authorities are advising locals to evacuate areas around Calbuco as there is a high risk of lahars and the risk of further eruption is high.

In other news a M7.8 earthquake (aftershocks of M6+) in Nepal this morning has caused extensive damage and a high number of injuries and fatalities due to building collapses in and around the capital.

Calbuco had erupted for the third time in eight days (bbc - http://www.bbc.co.uk/news/world-latin-america-32545006 ) A nice May day present - shovelling volcanic ash

underwater eruption. Why is gaia angry?

Ringing of the atmosphere (actually ripples of electron charge density in the ionosphere) spotted in GPS data, arising from the Nepalese earthquake:

As the Earth below trembled it repeatedly pushed on the lower atmosphere and those waves propagated up into the upper atmosphere. This disturbed the free electrons up there (stripped off atoms by the intense UV of the Sun) resulting in a variation in GPS signal arrival times (the radio path is altered by these waves and is one of the main sources of positional error in satellite navigation systems). This variation appeared in the receiver data (some 400km from the epicentre) just over 20 minutes after the quake.

2hats - thanks for that, fascinating ! I didn't know about electron charge density / earthquakes / GPS or their relationships, so I've learnt something today - I should be more careful.

A fairly large 7.4 has just occurred (within the last hour) in the vicinity of Everest on the Nepal/China border.

Interesting to note that some areas in Nepal have been shifted +/- 1.5m or so by the recent earth movements. Initial satellite data also suggests that (not entirely unsurprisingly) Everest may (perhaps) have reduced in height by a couple of centimetres or so (though this is yet to be confirmed through in situ GPS data) and moved sideways slightly.

e2a: Follow up quakes of 5.6 and 6.3 reported in quick succession in the Everest region within the last hour.

Mount Shindake in Japan (Kuchinoerabu Island in Kagoshima Prefecture) erupted early this morning. People are being evacuated. Pyroclastic flows reported. The ash plume has reached 9km altitude. Aircraft routing not yet affected.

Could start a new thread but I thought I'd drop this in here

Very strong evidence of active volcanism on Venus has been observed by ESA's Venus Express spacecraft. Active and dynamically changing hot spots seen at the surface and near-surface, moving/changing location, with temperatures consistent with hot lava flows. Over the period of those observations the levels of sulphur dioxide were seen to rise sharply and fall as well (which quite possibly would indicate a contemporaneous eruptive period).

And Mt Sinabung has erupted, again, today 25th June 2015 - last spat was (I think) on the 16th.

Mount Raung (Indonesia) has erupted in the last few days, producing an ash cloud that is disrupting flights in the region (particularly towards the SE of the volcano) - primarily affecting those to/from Bali:

Erruption ash from 5 volcanos in Indonesia have made it a bit dark over there.

http://abcnews.go.com/Technology/wireStory/eruptions-ash-volcanoes-shroud-skies-indonesia-32610505

Eruptions of ash at five volcanoes shrouded the skies over parts of the Indonesian archipelago Wednesday, forcing three airports to close.

Mount Raung on Java island blasted ash and debris up to 2,000 meters (6,560 feet) into the air after rumbling for several weeks, government volcanologist Surono said.

Ash erupted also from Gamalama and Dukono mountains on the Moluccas islands chain, Sinabung volcano on Sumatra island and Mount Karangetang on Siau island, darkening the skies, Surono said.

A total of more than 13,000 people have been evacuated due to the volcanic eruptions since last month, mostly from around the slopes of Sinabung in Tanah Karo District, added Surono, who uses a single name.

"Our evaluation showed there is no extraordinary natural phenomenon that triggered simultaneous eruptions of the five volcanoes," Surono said, adding that all the eruptions are natural and normal occurrences in a nation with about 130 active volcanoes.

We could really do with some volcanoes in Britain - it would give us something else to talk about than the weather. We could plonk it in East Anglia - and finally make that part of the country interesting.

 

[2hats]

It'd give the locals something to climb.

 

[StoneRoad]

nah, NFN !
they'ld worship it and if they could find any, sacrifice virgins ....

... only jokin' !!
