16 julio, la actividad del volcán 2012

Actualización de 19: 52 UTC : ER Reader Roland informed us a few moments ago of a glowing cloud above etna's Bocca Nuova (Sicily, Italy) (this vent activity is going on for a couple of days and is visible at night). Click here for the webcam showing the glowing cloud.


Thing's appear to be quieting again at most volcanoes we have reported on the past few days.

At El Hierro (España), seismicity has dropped to very low levels with no events over M2.5 in the past 24 hours.

In Guatemala, volcanic tremor is reduced at both Pacaya (Estación de PCG) y Fuego (station FG3) with respect to the past few days

Volcano-tectonic seismicity is on the rise at Popocatépetl (México) and perhaps at Galeras (Colombia) with some tremor thrown-in (station CUVZ).

SO2 output, as measured by satellite, remains high at Popocatépetl, while SO2 emission from recently eruptive Nevado del Ruiz (Colombia) has become more fitful.

We do not want to withhold you the activity on Mount Pagan (Mariana Islands) on July 11. Gas and ash clouds has been observed up to a height of 5000 ft (1500 m). The volcano summit is at 570 m. Mariana Islands authorities are reporting ash fall at the island.

Actividad observado por los satélites

An ash cloud was observed at 10000 ft (3 km) from Sakura-Jima volcano (Japan). The summit of the volcano is at 1060 m.

SO2 satellite images show a further strong emission at Niyragonga volcano (República Democrática del Congo)

An ash plume has been detected at 8000 ft (2.4 km) earlier today at Batu Tara volcano (Komba Island, Indonesia)

    ETNA:
    Op websites, o.m. van LAVE, geeft de webcam duidelijk rode gloed weer van lava-activiteit in de Bocca Nuova. Dit is trouwens reeds enkele dagen aan de gang.
