Increased activity reported at Colima volcano in Mexico

July 15, 0211MEXICO – The Colima Volcano is currently one of the most active volcanoes in Mexico and in North America. It has erupted more than 40 times since 1576. Despite its name, only a fraction of the volcano’s surface area is in the state of Colima; the majority of its surface area lies over the border in the neighboring state of Jalisco, toward the western end of the Eje Volcánico Transversal mountain range. It is about 485 km (301 mi) west of Mexico City and 125 km (78 mi) south of Guadalajara, Jalisco. There are two peaks in the volcano complex: Nevado de Colima (4330 m), which is older and inactive, lies 5 kilometers north of the younger and very active 3860 metre Volcán de Colima (also called Volcán de Fuego de Colima). Since 1869-1878, a parasitic set of domes, collectively known as El Volcancito, have formed on the northeast flank of the main cone of the volcano. The last eruption of the volcano was in 2010. –Wikipedia
Mexican news foroTV mentions today Colima volcano awakes today and breaks 10 meters of its dome causing several landslides.

    Harmonic tremor spike from Hamarinn volcano
    Posted on July 16, 2011 by Jón Frímann
    There seems to be a small harmonic tremor spike taking place in Hamarinn volcano (Bárðarbunga volcano) at the moment. This tremor spike is not strong at the moment. This tremor spike appears to have been pre-seeded by few long period earthquakes (not all of the earthquakes seen on Skrokkalda are from Hamarinn volcano, few are from Katla volcano), but that suggests that magma is on the move in Hamarinn volcano. But this would the second harmonic tremor in a time period of 48 hours it seems.

    The harmonic tremor spikes can be seen at the end of this tremor plot. Copyright of this picture belongs to Icelandic Met Office.

    Currently it is impossible to know what happens in Hamarinn volcano. As it’s pre-eruption behaviour is rather unknown. But if there is a eruption in this area I am expecting a lot of earthquakes, with size well over ML3.0. http://www.jonfr.com/volcano/?p=1201
