Bulletin of extraordinary activity of the Nevado del Ruiz volcano, February 6, 2016.
Subject: Activity Bulletin of the Nevado del Ruiz volcano. The level of activity Yellow or (III) persists: changes in the behavior of volcanic activity.
Regarding the monitoring of the activity of the Nevado del Ruiz, the Colombian Geological Service reports that:
On February 6, 2016 at 20: h39 (local time), a volcano-tectonic earthquake , associated with the fracturing of the rock inside the volcano, with a magnitude of 3.6 ML, located in the North sector of the crater Arenas, at a depth of 4.9 km, was recorded. This event was reported as felt by the inhabitants of the area of influence of the volcano, as well as in the municipalities of Manizales and Villamaría.
The localization obtained by the OVS–Manizales is:
Latitude: 4 ° 55’95 « N
Longitude: 75˚ 19’84 « W
Depth :4.9 km
Magnitude: 3.6 ML
It is recommended that the community continues to monitor any changes occurring in the volcano.

Popocatepetl , Mexico :
February 08 , 2016 (1700 GMT February 08)
In the last 24 hours the seismic records of the surveillance system at Popocatépetl volcano registered 33 low-intensity exhalations mainly accompanied by steam, gas and ash. The most important were recorded this morning at 06h53 and 07h33 .
During the yesterday and early today was observed a slight emission of steam, gases with a light ash content.
At night incandescence was observed over the crater increasing with some exhalations .
During this morning a steam-and-gas emission has been observed, moving towards northeast .
CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments .
This type of activity is included within the scenarios Volcanic Traffic Light Yellow Phase 2.

Guallatiri , Chile :
The National Emergency Office (Onemi) said that during the early hours of Saturday, Guallatiri volcano, located in the commune of Putre, in the region of Arica y Parinacota registered a type of « volcano tectonic » earthquake .
According to the report, the monitoring stations around the massif, recorded seismic activity at 17h21, with its epicenter at 8.9 kilometers south–southwest of the main crater, and a depth of 3.6 km . Onemi also explained that so far there have been 31 aftershocks of lesser magnitude, without being felt by communities in neighboring areas.
Following the above, the level of technical alert level remains at green. In addition, the National Geology and Mining Service (SERNAGEOMIN) continue the monitoring online of the volcano and the Regional Directorate of Onemi will maintain coordination with members of the civil protection system to provide early warning against a possible emergency situation caused by the behavior of the volcano.
One of northern Chile’s most active volcanoes, Volcán Guallatiri is a symmetrical ice-clad stratovolcano at the SW end of the Nevados de Quimsachata volcano group. The 6071-m-high Guallatiri lies just west of the border with Bolivia and is capped by a central dacitic dome or lava complex, with the active vent situated at its southern side. Thick lava flows are prominent on the lower northern and western flanks of the andesitic-to-rhyolitic volcano. Minor explosive eruptions have been reported from Guallatiri since the beginning of the 19th century. Intense fumarolic activity with « jet-like » noises continues, and numerous solfataras extend more than 300 m down the west flank.

Momotombo, Nicaragua .
New observations made by the experts in volcanology of INETER, confirmed the existence of cracks on the southern and southeast flank of the volcano, where there has been the release of small amounts of lava and explosions during the last weekend. It was observed a glow at night.
This type of crack on the slopes of Momotombo took place on several occasions during past eruptions.
The micro-seismic activity of the volcano continues.
Seismic amplitude in real time (RSAM) remains at low and moderate values between 150 and 480 units.
The gas emission is moderate, which are mainly moved by the wind in a south–westerly direction towards Puerto Momotombo.
