Chaparrastique , El Salvador :

Tuesday, January 12, 2016

Around 5:20 this morning, the volcano Chaparrastique , in San Miguel, issued ashes, generating a column of about 400 meters to the west, to the town of San Jorge. Ash falls were reported in the villages of   Caseríos La Piedra ,  Moritas and  Placita.
At the time of publication of this report the volcano continues to emit ash and gas at low altitude.
Local observers confirm the ash falls in the region. The images from the surveillance cameras show the emission of ash. At the moment there are no reports of damag



Special Report No 6 on the activity of Chaparrastique volcano which remains above threshold values
Thursday, 14 January 2016 11:53

In the last 12 hours, the values of the seismic vibration of the volcano have stabilized above the threshold, fluctuating between 366 and 465 RSAM units on average per hour, with an average of 400 units, a situation that continues since Wednesday.
The emission of gases and water vapor goes from the central crater and the energy levels RSAM remain variables, indicating the accumulation of energy and instability in the internal system of the volcano (Figure 1 ).


Figure 1: measurement of the amplitude of the seismic signal averaged over time, from 300 to 400 units.

Captured by the surveillance camera located on the hill El Pacayal, the images show a combination of weather clouds with gas from the crater. The gases are transported in accordance with the wind direction, which this morning was looking west.

January 12: The emission of volcano ash began to 5:20 local time (11:20 GMT) and the elevation of the ash cloud emitted from the crater is between 1,200 and 1,500 meters.

Volcanologists of MARN were present in the region last January 13 and confirmed that the wind in the volcano area moves the ash deposited during the eruption process and remobilized it, moving down the volcano on the southwest flank.


Mobilization of ash and its movement towards the southwest of the volcano, by the wind.

The interpretation of the monitoring data show that the internal system of the volcano is still unstable, and this behavior may continue for the next few hours or days. Please note that it is not excluded that an increase in the activity of the volcano blows again ash emissions and even the possibility of the presence of magma to the surface .

Including the eruption of December 29, 2013, there were a total of 22 similar eruptive episodes to date; however, this is one of the more intense events.

Popocatepetl , Mexico:

January 14, 11:30 h (January 14, 17:30 GMT)

During the last 24 hours through the monitoring system at Popocatépetl volcano 4 low-intensity exhalations were registered. Due to weather conditions we were unable to corroborate the seismic signal with emissions.
Incandescence was observed during short time periods .



At the time of this report there is no visibility to the volcano, however it has been observed the presence of snow due to the current weather conditions; added to this, the Volcanic Traffic Light continues Yellow Phase 2 for which we recommend to the people not to cross the safety limits established.

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.

Special Volcanic Activity Report (REAV), Bio Bio Region.

January 14, 2016, 06: 00HL

The National Geology and Mining Service (SERNAGEOMIN) Volcano Observatory of the Southern Andes (OVDAS), announces that today, Thursday, January 14, 2016 from 4:45 local time (7:45 GMT) and 4:49 am (7:49 GMT), the monitoring stations installed near the Copahue volcano, recorded four (4) earthquakes associated with the fracturing of the rock (volcano tectonic).

 Copahue (Chile-Argentina). state of the crater on 27/12.

The earthquake of greatest energy had a magnitude of 3.8 ML (local magnitude) and was located 16.4 km eastnortheast (ENE) of the El Agrio crater.

The location obtained was:
STARTING TIME: 04: 45 hl (GMT -3)
Latitude: -37.775333 °
Longitude: -71.015667 °
Depth: 6.46 km
Local magnitude : 3,8(ML)

OBSERVATIONS: It should be noted the perception of the event by the community in the area of Caviahue (Argentina).
No changes were recorded in the surface activity due to the event.
The level of technical volcanic alert level remains at yellow.
The SERNAGEOMIN -OVDAS continuous online monitoring, and report timely to the changes in volcanic activity in the region.
