Well Pop likes going pop when I'm not looking apparently it's had 91 explosions in over a 24 hour period. Nevado del Ruiz is rumbling nicely as well http://www.ingeominas.gov.co//Manizales/Sismografos/Perspectiva-del-Azufrado-en-el-Volcan-Nevado-del-R.aspx

I wonder what are the chances of eruption before the end of summer...

[Paranoid]

The weather on the webcam looks as terrible there as it is here, you can see stuff being blown around (if you can see past all the dust and water that's stuck to the lens). Odd as the forecast on the IMO showed light winds, maybe it's a bit windier near the coast.

Ah I post I made seems to have disappeared. Interesting report on the biggest eruption of the 20th century. http://pubs.usgs.gov/pp/1791/ Download the report from the right hand side.

An earthquake swarm with possibly hundreds of small quakes has been detected at Chile's San Pedro-Pellado (or Tatara-San Pedro) volcano

Stromboli volcano (Italy) activity update: strong and frequent explosions at summit crater

A series of earthquakes began in the sub-glacial volcano Katla in Mýrdalsjökull, south Iceland, shortly before 5 am this morning. Between 5 and 6 am 14 minor tremors were registered there, the strongest of which was 1.6 points on the Richter scale. Between 6 and 8 am, six other minor quakes were picked up by the Icelandic Meteorological Office’s sensors, but after that the series subsided

Katla is keeping us interested!The quakes are very small though so maybe some of them are due to seasonal glacial melt.

just had a mag 2 there

as you say karyo it could be glacial melt

but the last one at 5km deep probably wasnt

keeping us interested as usual

Yes John, at 5km it is deep enough to be a 'proper' earthquake.

Katla had a quiet start to the year but the latest activity is interesting.

I'd love her to blow when we have a high pressure spell which is ideal for volcanic sunsets! :-)

Volcano Activity in Guatemala

Maybe for its violent history, Guatemala's Fuego volcano is being closely monitored Monday by experts since it is increasing its activity for the third time this year. According to National Institute for Seismology, Vulcanology, Meteorology and Hydrology of Guatemala (INSIVUMEH), the 3,763-meter above sea level volcano is on effusive eruption phase. Despite this not dangerous yet condition, INSIVUMEH warns about the possibilities of an increase of the volcanic activity and that eruptions as those of May 19 and 25 are registered.

Worldwide VOLCANO activity and news – June 11 update

Potential Iceland eruption could pump acid into European airspace

11 June 2012

AGU Release No. 12-28

For Immediate Release

WASHINGTON—A modern recurrence of an extraordinary type of volcanic eruption in Iceland could inject large quantities of hazardous gases into North Atlantic and European flight corridors, potentially for months at a time, a new study suggests. Using computer simulations, researchers are investigating the likely atmospheric effects if a “flood lava†eruption took place in Iceland today. Flood lava eruptions, which stand out for the sheer amounts of lava and sulfurous gases they release and the way their lava sprays from cracks like fiery fountains, have occurred in Iceland four times in roughly the past thousand years, records indicate, the most recent being the deadly and remarkable eruption of Iceland’s volcano Laki in 1783-84.

When Laki sprang to life on June 8, 1783, it generated a sulfuric acid haze that dispersed over Iceland, France, England, the Netherlands, Sweden, Italy, and other countries. It killed a fifth of Iceland’s population and three-quarters of the island’s livestock. It also destroyed crops, withered vegetation, and sowed human disease and death in several Northern European nations. During the eight months that Laki erupted, the volcano blasted 122 million tons of sulfur dioxide into the atmosphere – seven times more than did the 1991 Mt. Pinatubo eruption in the Philippines and approximately 50 to 100 times more per day than Iceland’s Eyjafjallajökull volcano released in 2010.

Hundreds of residents in northeastern Indonesia fled their homes on Wednesday after a brief eruption at Mount Gamkonora, spewing towering columns of ash and smoke and prompting officials to raise the volcano's alert level to the second-highest state

Plumes of smoke

and ash are continuing to rise from Colombia's Nevado del Ruiz volcano.

http://www.bbc.co.uk/news/world-latin-america-18481694

[The PIT]

Apparently the Eruptions at Nevado del Ruiz contain no new material and are mainly Pheatic in nature. Magma still seems to be rising judging by the tremor so new material maybe erupted in the future or it may simply go quiet.

MT Cleveland has gone pop as well. Lava dome collapse?? Source http://www.wired.com/wiredscience/category/eruptions/

I've just seen a trailer on the Beeb for a forthcoming four-part series "Volcano - Live" (9-12 July) with Iain Stewart and Kate Humble, coming from Kilauea. So that's two excitable presenters, rather than one!
