Seeing as this is likely to run and run, can we put in this thread any links, resources etc. to help folk seeking to follow the eruption.

Discussion can continue in the other thread as normal.

:D

An account of the previous eruption of Ejafjallajokull in 1821. (Note the spelling of Katla as "Kolla" - "ll" in icelandic is pronounced "dl" or "tl" - hence the pronunciation of Ejafjallajokull, which we also got wrong in 1822, is something like Eya fiat la yokhut.)

XXVI. Account of the Eruption of the Old Volcano of Eyafjeld Jokkul in Iceland, in December 1821.

THE remarkable fall of the barometer which took place almost simultaneously throughout all Europe, on the 25th of December 1821, and which in some cases was accompanied with an agitation of the magnetic needle, induced many persons to conjecture that some tremendous convulsion of nature must have visited some part of the globe. This conjecture has at last been verified by a volcanic eruption of the old volcano of Eyafjeld Jokkul, which has been in a quiet state since the year 1612.

This mountain, otherwise called Cape Hecla, is about 5666 feet in height. It is nearly equidistant from Kolla and Hecla, and is the southermost of the chain where the dreadful eruption broke out about the middle of the last century.

On the 19th December 1821, the eruption began. The crater was formed at the distance of five miles from the minister's house at Holt, and discharged itself through the thick mass of ice that enveloped it, and which is seldom melted. The ice was dispersed in every direction, and a mass, 18 feet high and 60 feet in circumference, fell towards the north. A number of stones, of different sizes, rolled down the mountain, accompanied with a noise like thunder; and this was immediately followed by a discharge of an enormous and lofty column of flame, which illuminated the whole country, and allowed the people at Holt to read as perfectly within their houses at night as if it had been day. Ashes, stones, gravel, and heavy melted masses of rock, some of which weighed about 60 Ib. were thrown up, and one of these last was found at the distance of five miles from the crater. On the day immediately following the eruption, a great quantity of the fine greyish-white powder of pumice * was discharged, and carried about by the wind so as to fall like snow, and cover the adjacent country. It penetrated into the houses through every opening. It exhaled a disagreeable smell of sulphur, brought on affections in the eyes, and occasioned diseases among the sheep in Vester Eyafjeld and Oster Landoe.

On the 25th of December, a violent storm raged from the south, and by the united action of the wind and the rain, the fields were cleared of the sulphureous dust which had covered them. On the 26th and 27th of December, there was a heavy storm from the north-east, and the barometer, which had been gradually falling since the 18th December #, when it was 29.16, had reached, on the 26th December, its lowest point at 28.49. It is a curious fact, however, that on the 8th of February the barometer fell to 27.25, a time when no earthquake was felt, and no apparent change had taken place in the eruption. On the 18th of February, the barometer, which had been at 29.42 on the 11th, fell to 27.72. So late as the 23d of February, the Eyafjeld Jokkul emitted smoke greatly resembling the steam of boiling water; and some persons were of opinion that the mountain had decreased, and was lower near the crater, as it evidently appeared to be when viewed in a direction from north to south.

It is stated that the water in the rivers that flow from the Jokkul and the surrounding mountains, had been considerably enlarged during the first day's eruption. A constant rumbling noise was heard in the vicinity of the volcano, attended occasionally by a dreadful crash, as if the immense masses of stones and ice were on the eve of being precipitated down the mountain.

Other two volcanoes to the east, in the mountains of Kolla and Oraefa Jokkul, are said to have broken out, but no certain information has been received on the subject.

The vessel which brought the account of the volcanic eruption to Copenhagen, left Iceland on the 7th of March; and it is reported that the sailors when at sea, again saw a violent fire in the direction of the volcano.

* This powder had a sulphureous taste, and burned when thrown into the fire.

# The observations on the barometer were made at Naes near Reikavig, by Dr Thorsteinson. A statement of it for October, January, and February, will be found in the Ann. of Phil, for June.

Latest flights and course of the FAAM (Facility for Airborne Atmospheric Measurements)who fly a BAe-146-301 out of Cranfield as a collaboration between the Natural Environment Research Council and the Met Office. They are plotting the expected fallout of the ash cloud 'as and when'.

When the volcano erupted we put all the cameras on one site to make it easy to view.

In addition we put them two at a time side by side so you get to monitor it easier.

Also with seismic data and full world earthquake links.

Plus Katla and Hekla cams ( just in case)
