Special volcanic activity report (REAV)
Tarapaca Region, 14 December 2016, 21h50 (local)

The National Geological and Mining Service (SERNAGEOMIN) discloses the following information obtained by the monitoring teams of the National Volcanic Monitoring Network, processed and analyzed by the Southern Andes Observatory:
Wednesday, December 14, 2016, at 08:12 local time (11:12 GMT), monitoring stations installed near the volcano Guallatiri, recorded one (1) earthquake associated with rock fracturing (volcano-tectonic). The event was located 8.9 km southwest (SW) of the main crater.



The location was obtained as follows:

Original Time: 08:12 HL (GMT-3)
Latitude: 18 ° 28’10.80 « South
Longitude: 69 ° 9’30.00 « West
Depth: 9.46 Km
Local magnitude: 3.4

At the time of this report, there were 22 events with similar characteristics but smaller magnitude . There is no information from authorities or communities on the perception of these events in neighboring areas.
The level of technical volcanic alert remains at GREEN.
SERNAGEOMIN continues monitoring and reports on changes in volcanic activity in the region in a timely manner.

Kilauea , Hawai :

19°25’16 » N 155°17’13 » W,
Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE


Activity Summary:
Kilauea Volcano continues to erupt in two locations. The episode 61g lava flow from Pu’u ‘O’o in the East Rift Zone is entering the ocean at Kamokuna. A younger branch of the flow is active near Pu’u ‘O’o and advancing slowly east. These lava flows pose no threat to nearby communities at this time. The lava lake at Kilauea’s summit continues to circulate, with periods of spattering occurring sporadically. Seismic activity continues at a low rate. Summit deflation continued and the lake level dropped slightly.


Summit Observations:
Last week, the average daily sulfur dioxide emission rate at the summit was approximately 5,000 metric tons/day, but has not been measurable over the past week. Summit seismic activity remains low overall. The summit continued to deflate over the past day. The level of the summit lava lake has dropped slightly with the deflation and was approximately 31.5 m (103 ft) below the vent rim as measured yesterday morning. The amplitude of summit seismic tremor fluctuated as spattering in the lake waxed and waned.


Pu’u ‘O’o Observations:
There were no obvious changes at Pu’u ‘O’o. Webcam views show persistent glow from sources within the crater and from a vent high on the northeast flank of the cone. The tiltmeter on the northwest flank of the cone showed a slight decrease over the past day. The sulfur dioxide emission rate from all East Rift Zone vents was about 340 metric tons/day when last measured on November 30. Seismicity in the Pu’u ‘O’o area continues at low levels.


Lava Flow Observations:
The episode 61g flow is still active and entering the ocean at Kamokuna, where activity has been concentrated on the east side of the delta. In addition, a younger branch of the episode 61g vent remains active east of Pu’u ‘O’o and is advancing slowly east at a rate of only a few tens of meters (yards) per day. The small breakout near the vent that began two days ago continues this morning and is mostly covering earlier episode 61g lava. The episode 61g flow poses no threat to nearby communities at this time.

Colima , Mexico :

19.514°N, 103.62°W
Elevation 3850 m

Based on webcam and satellite images, and information from the Mexico City MWO, the Washington VAAC reported that ash plumes from Colima rose to altitudes of 4.6-7.3 km (15,000-24,000 ft) a.s.l. during 7-11 December and drifted almost 170 km in multiple directions.



Bernard Buick notes in his blog ( « The Colima presented on December 13 a sustained explosive activity: I counted eight on the webcam (at 5:21, 9:06, 11h07, 15h38, 17h45, 19h31, 22h16, 23h21), but this number is not exhaustive. They were accompanied by plumes of ashes rising between 2,000 and 3,000 meters above the crater, and for the episode of 11h07, d A small pyroclastic flow in the direction of Jalisco « .

Turrialba , Costa Rica :

Activity report of the Turrialba volcano:
14 December 2016

Today, the amplitude of the seismic signal of the Turrialba volcano remains variable, at a low to medium level, but during certain periods of time.
During the periods when visual observations were made, a plume not exceeding 100 to 200 meters was observed with a content of gases, aerosols and sometimes low emissions of ash particles.



The direction of the wind changed between the Southwest and the North-West according to the weather station IMN.
No ash falls are reported.
