Fuego volcano (Guatemala): change in eruptive style: large lava flows
Friday Sep 14, 2012 09:02 AM | Age: 3 hrs
The eruption of the volcano has undergone a change from explosive to mainly effusive over the past few hours, INSIVUMEH reports in the latest bulletin
last night (22h00 local time). Instead of a large sustained ash column, there are now smaller pulsating ash emissions reaching 3-700 m height, but
instead the volcano is producing large (for Fuego) lava flows between 900 and 1,000 meters long and 150 wide. The different activity is also leaving a
different type of seismic signature and has remained stable over the past hours.
According to information obtained by observers nearby and security forces positioned in Morelia Panimache, one lava flow is traveling down the Ceniza
canyon (SSW flank), and another towards the ravine Las Lajas and into Barranca El Jute (SE flank) where it is threatening to cut roads.
Despite the dominantly effusive activity, small pyroclastic flows still occurred as well, at a rate of about one per hour, mainly to Ceniza canyon,
and producing fine fine ash columns. Ashfall was last reported only in Panimaché, Morelia, Yucales and Sangre de Cristo.
