Soputan , Indonesia :

Based on visual observation of the main crater of Soputan, it was observed white smoke emission, low to medium, approximately 20-100 m above the peak of G. Soputan. Photos taken in the last two days have shown an increase in the thickness of the smoke that went from white to light gray with a height of 300 m above the Soputan. The image acquired by the thermal camera showed an incandescent, giving strong indications of an increase in the arrival of liquid magma to the surface.


Seismicity indicates an increase in quake swarms (HB) earthquakes and avalanches in recent months. On January 4, 2016, the number of avalanches and seismic swarms increased significantly, indicating an increase in the arrival of magma to the surface. Meanwhile, during the last week, the number of recorded volcanic earthquakes oscillated between 2-3 events per day.



The calculation of the seismic amplitude (RSAM) showed a significant increase, particularly in the period of the past 12 hours. Dominant frequency data of seismicity of Soputan indicates an increase in high frequency seismicity that can reflect the fracture processes of volcanic rocks beneath the volcano. The tilt measurement data (slope), showed no significant change and indicate the presence of bubbles under the Soputan volcano.


The results of the visual observation data analysis, seismic and deformation (inclinometer) all indicate a sizeable increase in volcanic activity, so that, from January 4, 2016 at 18:00, the levels activity of Soputan is relieved from Waspada (level II) to Siaga (Level III).
If there is a change (increase / decrease) significantly in the volcanic activity of Soputan, the level of activity will be evaluated again to be adjusted to the level of the threat.

Volcanic ash emitted by the Soputan in Minahasa region of Southeast and South Minahasa worried residents who are beginning to feel their effects.





« Since early morning, residents in the village of Raringis and Noongan are concerned about cleaning the tin roofs of their homes. Crops have been affected by the ash from the Soputan« , said the residents.





The two villages are located in the district of West Langowan, Minahasa. The ash falls have also reached Kanonang.
The Soputan has again experienced an eruption Tuesday morning around 6:38 p.m. with high column eruption reached about 6.5 km. The wind direction during the eruption was at Southwest.
The eruption was accompanied by pyroclastic clouds over a distance of about 2.5 km to the south .









The eruption of Mount Soputan January 5th, 2016 at 18:38, the height of the eruption column reached 6.5 kilometers from the summit, and go to the southwest ,an eruption accompanied by clouds of pyroclastic flows at 2 , 5 km away to the south.

Yellowstone, United-States :

44 ° 25’48 « N 110 ° 40’12 » W,

Summit Elevation 9203 ft (2805 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN

During December 2015, the University of Utah Seismograph Stations, responsible for the operation and analysis of the Yellowstone Seismic Network, reports 46 earthquakes were located in the Yellowstone National Park (YNP) region. The largest event was a micro earthquake of magnitude 2.3 on December 20, at 01:37 AM MST, located about 12 miles north of the East Entrance Station to Yellowstone National Park. No earthquake swarms were located in December.
Yellowstone earthquake activity in December is at low background levels.



Ground deformation
GPS stations in Yellowstone continue to show little or no ground movement.

The Yellowstone Volcano Observatory (YVO) provides long-term monitoring of volcanic and earthquake activity in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park. YVO is one of the five USGS Volcano Observatories that monitor volcanoes within the United States for science and public safety.

Reventador , Ecuador :

High activity persists on the volcano. The observations in the morning note a water vapor émission to the northwest.
ANNEX Technical and observations:
From 11:00 (TL) yesterday to 11:00 am (TL) today have been registered 35 long period events (LP), 6 episodes of harmonic tremor (TA) and 48 explosions (exp).
Observations of emissions and ash:
In the morning, we could observe gas and steam emissions, as well as small amounts of ash that had a Northwest direction.
Rains and lahars:
There was no rain in the volcano area.



This report on a daily basis will be published at 12:00 (TL). In the case of an increase or change in the behavior of the volcano it will be immediately issued a Special Report.
