Etna`s Eruptions Keep Going and Going

Italy’s Mount Etna is currently in a period where short bursts of activity, each lasting a few hours, are interspersed with quiet periods lasting several days or weeks. Thirteen eruptive episodes, or paroxysms, had occurred by mid-September 2011.

During a typical paroxysm, lava fountains at the New Southeast Crater send flows down the eastern slope of the volcano, often accompanied by a dense ash plume.

According to the Istituto Nazionale di Geofisica Evulcanologia, “Etna is the largest and tallest volcano of Europe, and one of the most active volcanoes on the Earth. Its eruptions occur both at the summit, where currently there are four craters, and from its flanks, down to a few hundred meters above the sea-level.  Summit activity can go on virtually continuously for many years or even decades, but it also often occurs during the intervals between flank eruptions

“New studies have revealed that this volcano is capable of producing violently explosive activity, like the Plinian eruption of 122 B.C. (B.C.E.). In recent years, especially since the late 1970s, there has been a significant increase in the frequency of explosive eruptive episodes, foremost at the summit craters. In particular, the summit eruptions of 1995-2001 included about 150 episodes of lava or fire fountaining (such episodes are often referred to as paroxysms), many of which generated tall columns of ash and gas.

The flank eruptions of 2001 and 2002-2003 have demonstrated that significant amounts of pyroclastic material (ash, lapilli, bombs, and blocks) can be also generated by flank eruptions. Differently from the usually short-lived summit paroxysms, pyroclastic fallout during flank eruptions can go on for weeks or even months, and impact life in the populated areas, besides representing a serious threat for traffic both on the ground and in the air.

  1. MR. ROBERT FELIX, if you read this I am with you on the climate situation. I think the ROOT cause of climatic change is the given strength or lack of strength of magnetic fields, generated by the sun and the earth, and modulated by the moon.

    The magnetic fields when weak give rise to persistence in weather systems ,and a slowness to their movement, which in turn, leads to more extreme climatic events.
    Let me say it like this. I think the sun sets the tables for the various items that control the climate to phase into either a warm mode(active sun) or a cold mode (inactive sun)

    ITEMS THAT CONTROL THE CLIMATE:

    SOLAR
    VOLCANIC
    ATMOSPHERIC CIRCULATIONS AO/AAO/NAO
    SOI INDEX LA NINA+ EL NINO-
    PDO/AMO
    COSMIC RAYS
    MAGNETIC FIELDS AS MENTIONED ABOVE
    MILANKOVITCH CYCLES IN THE BIG PICTURE

    Now Robert, I feel all those items in turn will influence the following :

    OCEAN HEAT CONTENT
    CLOUDS
    SNOW COVER
    PRECIPITATION
    ALBEDO

    Now if the degree of magnitude is LONG enough in DURATION, and STRONG enough in INTENSITY,of those items I mentioned with the sun setting the tables, I feel certain THRESHOLDS could be met, which could from time to time bring about abrupt climatic change.

    I say if the sun can remain in this PROLONG SOLAR MINIMUM , all the factors I mentioned above will keep phasing into an ever increasing colder mode.

    I say if the solar flux reading can average 90 or lower ,with spurts from time to time ,(which will promote more geological activity) that this decade will continue to be the one of climatic extremes, and high geological activity, along with a decline in temperatures.

    Climatic extremes and geological activity ,reacting much faster to the prolong solar minimum, then the temperature decline, due to the fact OCEAN HEAT CONTENT , is slow to change, and this keeps the temperatures from reacting as fast as they would otherwise, to the PROLONG SOLAR MINIMUM.

    I say in closing in order to put an end to this hoax which is of course the man made global warming CO2 induced stupidity , we need the prolong solar minimum to continue.

    Past history suggest that when the sun was in a similar position, in respect to the solar system, as it is now, that each time a prolong solar minimum of various degrees of duration and magnitude did come about. Based on past history, I am confident that this time will be no different.

    Thanks for this great website ,and all the great work you have done in this field.
