The volcanic unrest continues around the world.
Enhanced volcanic activity at Fuego (Guatemala), Popocatepetl (Mexico), Ambae (Vanuatu) on November 4-5, 2017.
The 11th eruptive phase of the year has begun at Fuego volcano in Guatemala with 6 to 8 explosions per hour, and generating ash plumes rising to 4,500-4,800 m asl.
Lava ejection reaches 100 meter over the crater and feeds two lava flows in the Seca / Santa Teresa and Ceniza barrancas – 1,200 and 700 meters long respectively. Small avalanches are observed up to the vegetation limit. Turbine degassing noises ring every 5 minutes.
Meanwhile, the Popocatépetl volcano exploded 4 times on Nov. 4th at 1:45, 6:08, 14:40 and 23:21. Ash falls are reported on Yecapixtla and Zacualpan de Amilpas. On Nov. 5th, an strombolian explosion occurred at 4:11, and was accompanied by ash falls on Telela del Volcan.
Additionnaly, Cenapred recorded five volcanotectonic earthquakes in three days.
The alert level remains unchanged: Amarilla fase 2.
Sustained seismic activity and minor eruptions at Ambae volcano have been reported by Vanuatu Geohazards on November 5, 2017.
Loud noises from incandescent explosions were seen and heard from the neighboring islands.
A M2.5 earthquake was recorded by the seismometers of the Volcanological Observatory of Piton de la Fournaise and was felt by residents of Reunion Island on November 4, 2017. There is considerable uncertainty about its location. The earthquake is of tectonic origin, but still could announce another imminent eruption of La Fournaise volcano?
Finally, a M5.1 earthquake hit 25km southwest of Redoubt volcano in Alaska.
The volcanic and seismic unrest continue around the Ring of Fire!
