    Latest news about the swarm of LA Palma

    There are already 58 earthquakes located on the south ridge of LA Palma and surely there are more without. The Seismic Swarm began on October 7 in the morning being the last earthquake located this morning October 9 at 06:11:37.

    The National Geographic Institute (IGN) will increase volcanic surveillance in LA Palma. Tomorrow Tuesday, the installation work of three mobile stations of the volcanic surveillance network will begin, which add up to the five fixed ones.

    The Director of the National Geographic Institute (IGN) in the Canary Islands, María José Blanco Blanco, will move to the island in the company of a multidisciplinary team specializing in geodetic, geophysical and geochemical techniques that will follow up on the ground of the tremors.

    "at the moment we can only see the seismic activity that continues although with a much lower frequency located in the same area, North of the canaries, where the entire seismicity of the seismic swarm is located", he explained white, and added that " it seems to be located at less depth, but it is true that the errors in the depths do not allow us to confirm that they are really getting smaller ". " we will make a densification of the volcanic surveillance network in LA Palma with three new mobile stations ", He's insured.
    Yesterday Maria José Blanco pointed out that earthquakes are being carefully analysed, stressing that "it is the first time that a swarm of earthquakes on earth has been recorded on the ground since the island has instrumentation". Seismic Surveillance was launched in the 70 s, approximately, with a first station in the ravine of the anguish.

    He insisted that " since we have the network, which has been dense for a short time, there has never been a seismicity of this style ". he stressed that " there is more seismicity than is being locating, but cannot be recorded because The earthquakes are very small ".

    Last hour: in view of non-REGULAR SEISMIC ACTIVITY - SEISMIC SWARM-registered since last Saturday in LA Palma, the territorial policy department, sustainability and security of the canary islands government, in implementation of the special plan for civil protection and risk-based emergencies Volcanic (Pevolca), has convened for the next Wednesday, 11 October, the scientific committee for the evaluation and monitoring of volcanic phenomena, in order to assess data from networks and surveillance stations on the island.

    Kirishima - Japão

    O vulcão Kirishima apresentou um aumento da atividade sísmica no começo do mês e isso fez com que o nível de alerta fosse aumentado para 2.
    Ontem o vulcão localizado na região de Kyushu, Japão entrou em erupção expelindo uma coluna de cinzas e gases.
    A JMA elevou o nível de alerta para 3 e a área ao redor do vulcão foi declarado como zona de exclusão.
    Houve registro de queda de cinzas em vilas próximas do vulcão.
    A última erupção havia sido registrada em setembro de 2011.
