Volcanic Activity from around the World

If that went off proper big time... bye, bye Sicily

Some recent research information about the January Tonga volcano. Estimated to have been the largest explosion since the 1883 Krakatoa eruption

An unusual area of interest developing at Campi Flegrei near Naples in Italy which is showing signs of unrest in recent months and has gathered pace in the last couple of weeks. A magnitude 4.2 earthquake occurred on the 27th of September that could be felt in Rome.

Last seismic crisis here was in the mid 80s but it settled down with no eruption.

Whilst most scientists agree an eruption seems highly unlikely it is still concerning given the location/population and evacuation plans are being dusted off...just in case

They may have to have a look now at precautionary evacuations I think. Not implement now but have ready to go. Second 4 + in 7 days.

Reports of lines of cars leaving those districts tonight

There is unrest in the Greek Islands in the last 24 hours around 20 km northeast of Santorini.

I was just looking on line at the annals of Ireland of monastic recording of severe weather events (mostly four masters). Alot can be attributed to volcanic activity in the NH. Even in the early medieval period which was relatively warm a record of 3 months the snow lay in one particular winter. This they say could have been the result of a big Katla eruption roughly they think about the same time. Other articles on line...Many scientists attribute a layer of ash deposited in the North Atlantic and across Europe some 12,000 years ago to a massive eruption of Katla.

And below.

In terms of human impact, the 1739 1741 cold spell was the worst recorded for Ireland. This was most likely due to a major volcanic eruption in Siberia. This eruption caused a climatically induced famine in Ireland which, in combination with the extreme cold weather, resulted in the estimated deaths of between 310,000 and 480,000 people (Dickson 1997). 1740 is the coldest year on record in Manley’s Central England Temperature Record, emphasising the uniqueness of this event (Manley 1974 and updates). Only one outdoor instrumental temperature value survives from this time for Ireland. This was -33.8C, which is nearly 14.8C lower than the modern record for Ireland. Even allowing for inaccuracy in the reading from a non-standard instrument, this is indicative of just how extreme was the cold.

So i see the VEI for Katla over roughly 1200 years is about 4 to 5 . Just wondering about katla eruption 12000 years ago this must have been much great than a VEI 5?

Is it possible a future Eruption of Katla could be greater than a VEI 5?

Kilauea in full flow….

….iceland svartsengi system should erupt within the coming weeks….

A magnitude 6.5 earthquake near Jan Mayen island in the Arctic Ocean was picked up by seismometers in Dublin and Valentia, County Kerry on Monday morning.

The British Geological Survey says the quake occurred at 2.33am and was measured at a depth of 10 kilometres.

With no permanent population, Jan Mayen Island is 55 km long and is partly covered by glaciers around the Beerenberg volcano.

The island is located on the Jan Mayen Rift Zone, an active transform fault zone in which the mid-ocean ridge between Europe and America is offset by approximately 200 km.
