Our giant Sicilian  would wake up?


But the INGV has made no news release since a few days (the last date of October 16), the tremor  remains flat, and the videos  show nothing.

Nevado Del Ruiz, Colombia :

Subject: Activity level of Nevado del Ruiz volcano.
Activity level Yellow or (III): changes in the behavior of volcanic activity.


Regarding the monitoring of the activity of the Nevado del Ruiz volcano, the SERVICIO Geologico COLOMBIANO through the OBSERVATORIO VULCANOLÓGICO Y SISMOLÓGICO OF MANIZALES, reports that:

During the last week, the volcanic system continued to show unstable behavior. The recorded seismic activity was mainly due to the fracturing of the rock in the volcanic structure. This type of seismicity was in the North, the North West, North East and South West areas of the Arenas crater and to a lesser extent in the South West. The depths were between 1.1 km and 8.8 km. The maximum magnitude recorded during the week was 2.3 ML (local magnitude), corresponding to an earthquake on October 21 at 9:53 (local time) at a depth of 3.4 kilometers. Two small increases in seismic activity occurred during the day on 22 and 23 October in different distal areas of the   Arenas crater.

Seismic activity associated with fluid dynamics in volcanic conduits, was characterized by the recording of LP type earthquakes (long time) and episodes of volcanic tremor of short duration. Some of these events were associated with emissions of gases and ash in the atmosphere, which could be verified by web cameras installed in the volcano region, official reports Pnnn and technical staff working in a ground mission in the volcano area of ​​influence. Seismicity related to fluid circulation is situated mainly in the Southeast sector of Arenas crater and near this one. The volcanic deformation measured from electronic inclinometers, GNSS stations and satellite images, which record changes in tilt, position and shape of the volcano during the last assessment period, showed no major changes.

The volcano continues to emit into the atmosphere of significant amounts of water vapor and gases, including sulfur dioxide. The column of gas, steam and ash reached a height of 2000 meters above the volcano’s summit on October 22. The direction of the dispersion of the column was in harmony with the wind regime, which during the week ranged from the Southwest and Northeast compared to the volcano but also the column was repeatedly observed during week with a vertical trend.

Fuego, Guatemala :

 

Fuego volcano, 50 km southwest of the capital of Guatemala, Tuesday reactivated its eruptive activity with explosions and ash release, stated the National Coordinator for Disaster Reduction (Conred).
The colossus of 3,763 m above sea level located between the departments of Chimaltenango, Escuintla and Sacatepequez, recorded its tenth year of eruptive phases, said David de Leon, spokesman from Conred, an institution in charge of civil protection.

The official explained that the volcano has lava flows, volcanic expulsion of gases and ash up to 4,700 meters above sea level, but said that initially do not need to evacuate nearby villages.
« We keep in constant monitoring of the volcano with local authorities and community leaders before any additional changes that have reached the volcano, » said De Leon.

For his part, the Institute of Volcanology instructed the civil protection authorities to step up monitoring of the volcano and recommended to the Directorate General of Aeronautical take preventive measures for air traffic.
Last February, the Fuego volcano eruption recorded a powerful forcing the authorities to declare a preventive alert and close the airport in the capital by the ash, which also affected the colonial city of Antigua Guatemala.
