Fuego - tremor on 03.11.2017 - station FG3 Insivumeh

The Fuego has since November 3 an increase in activity, with 6 to 8 explosions per hour, accompanied by ash columns amounting to 4,500 - 4,800 m asl. before dispersing west and southwest about 15 km., and regular degassing with train noises every 5 minutes.
The FG3 seismic station shows an increasing tremor, suggesting a possible new eruption cycle.

At Sheveluch, the eruption continues, as well as the growth of the dome, characterized by a viscous lava flow north side, and a strong fumarolic activity.
A thermal anomaly was detected from October 26th to 30th and November 1st and 2nd; the other days, the volcano was not visible because of the clouds.
On November 2, an explosion was accompanied by a plume at more than 8,000 meters asl, drifting to the northeast.

Costa Rican volcanoes show a relative return to calm: only a permanent degassing, without presence of ash, is detected in Turrialba and Poas during the last 24 hours.
No eruption at Rincon de La Vieja for the same amount of time.

At Yellowstone, the first significant snowfall are coming.

A little reminder to winter travelers: some roads will soon be closed to normal traffic, only to become accessible to snowmobiles and snowcoaches.

On November 6, all roads will be closed at 8 am, except for the north entrance - north-east entrance.
