“Evacuation of smallest Canary Island begins after earthquake ‘swarm’ sparks fears of volcanic eruption” — Daily Mail, UK newspaper

I expect this item will interest those working on a CME or planetary alignment linkage with earthquakes, or in this case volcanic activity.

    The figure since 17th July 2011 is 8771 earthquakes.

    What has happened.

    Until September 29, the network of volcanic monitoring of follow-up 24 h of the Institute
    Geographic national, has registered and located 17 July, 8771 earthquakes from the past with
    epicentres both North and South of the NW Ridge and depths between 10 and 14 km.

    The number of events directions by the population is 50, II, III and IV intensities on the scale
    M.S.K. The magnitude of this series reached a value of 3.8 on the Richter scale.

    This seismic phenomenon is accompanied with surface deformations, which until the
    time reached the 35 mm.

    Last week (sep 23‐29). 1127 Earthquakes have been located. In this period have been senses
    the following 44 events with their respective maximum intensities:

    [list not shown here]

    During September 29 the number of sensed events greater than Richter scale magnitude 3.0, was 8”

    For those who are interested here’s an English translation. 

    Between July 17th and September 29th the monitoring network of the National Geographic Institute
    recorded 8,771 earthquakes, with epicenters located both to the north and the south of the NW
    axis (? – not clear what “dorsal” means) and with depths of between 10 and 14km. Fifty of these
    events, with intensities of 2, 3 and 4 on the MSK (Medvedev-Sponheuer-Karnik) scale, were felt by
    local residents. The strongest had a magnitude of 3.8 on the Richter scale.

    Ground movement accompanying the earthquakes has now reached 35mm.

    1,127 earthquakes have been recorded in the last week (23-29 September). Over this period 44
    events with the intensities listed below have been felt (list follows):

    Latest update from Jon Frimann:

    Magma on the move in El Hierro 3rd October 2011
    But it is now clear that magma is on the move upwards. So far the magma seems to be around 10 km up in the earth crust under El Hierro. So it is clear that the magma is on the way up and most likely preparing for a eruption.

    El Hierro little paused
    Katla Up !

    Little trigger CME

    “To he geoeffective, the
    solar wind from a coronal hole or from a CME has to first
    arrive at the Earth, so the geoeffectiveness of solar wind
    from a both coronal hole and from a CME mainly.
    depends on their position relative to the Earth. For the
    CMEs an additional factor is their size and speed. Faster
    and wider CMEs are more geoeffective”



    where is Rog ?
    ok ?

    Latest update from Jon Frimann:

    Eruption at El Hierro volcano, Canary Islands
    At 04:18 UTC on 10 October, 2011 a eruption did start somewhere close to the El Hierro volcano Island (but inside El Hierro volcano system). So far nothing has been seen to this eruption, so location is uncertain at the moment. At the moment this eruption has only been confirmed by harmonic tremors seen on seismometers on El Hierro island.

  8. malagaview says:

    From Earthquake Report:

    authorities have finally confirmed that an eruption took place on the ocean floor 5 km from Restinga, the southernmost location on El Hierro. IGN (Spanish seismological agency) has set the eruption depth at 600 meters.
