Special volcanic activity report (REAV)

Maule Region. October 16, 2016 8:30 (local time).

The National Service of Geology and Mining (SERNAGEOMIN) publishes the following information obtained by the teams of the Volcanic Monitoring Network of the National Observatory, processed and analyzed at the Volcanological Observatory of Southern Andes, interpretation center data from the SERNAGEOMIN:

Sunday, October 16, 2016 at 07:50 local time (10:50 GMT), the monitoring stations near the Planchon-Peteroa volcanic complex, recorded one (1) earthquake associated with rock fracturing (volcano – tectonic) . The event was located 37 km North-West (NW) of the main crater.

The location was located as follows:

TIME OF ORIGIN: HL 7:50 (GMT-3)
LATITUDE: 35 ° 12 ’31 « South
LONGITUDE: 70 ° 35 ’90 « West
DEPTH : 4.8 km
LOCAL MAGNITUDE : 3.2 (ML)

At the time of publication of this report, there have been three aftershocks of lesser magnitude. No significant changes were observed in the surface activity recorded by IP cameras.

SERNAGEOMIN continuous online monitoring and report timely to the changes in volcanic activity in the region.

BULUSAN VOLCANO BULLETIN 17 October 2016 8:00 A.M.

Bulusan Volcano’s seismic monitoring network recorded twenty four (24) volcanic earthquakes during the past 24 hours. Steaming activity could not be observed due to thick clouds covering the summit. Sulfur dioxide (SO2) emission was measured at an average of 79 tonnes/day on October 12, 2016. Precise leveling data obtained on August 16-25, 2016 indicated slight inflationary changes of the edifice relative to May 2016. Moreover, ground deformation data from continuous GPS measurements as of 30 September 2016 showed inflationary trends since July 2016.

BULUSAN VOLCANO BULLETIN No. 2 17 October 2016 9:00 A.M.

Bulusan Volcano generated a minor phreatic eruption today, 17 October at 7:36 AM. The event lasted for approximately 24 minutes based on the seismic record. This eruption originated from the southeast vent and produced a dirty-white to grayish ash column that reached a height of 1,000 meters. Bulusan’s seismic monitoring network recorded a total of twenty-four (24) volcanic earthquakes during the past 24 hours. Sulfur dioxide (SO2) emission was measured at an average of 79 tonnes/day on October 12, 2016. Precise leveling data obtained on August 16-25, 2016 indicated slight inflationary changes of the edifice relative to May 2016. Moreover, ground deformation data from continuous GPS measurements as of 30 September 2016 showed inflationary trends since July 2016.

Alert Level 1 (abnormal) remains in effect over Bulusan Volcano. This indicates that hydrothermal processes are underway beneath the volcano that may lead to more steam-driven eruptions. The local government units and the public are reminded that entry to the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to the possibility of sudden and hazardous steam-driven or phreatic eruptions.

Colima , Mexico :

The National Coordination of Civil Protection issued a notice of termination of the emergency declaration, which was published October 3, 2016, for the municipalities of Colima, for the presence of the volcanic eruption.

The National Civil Protection Coordination of the Interior Ministry announced the termination notice of the declaration of emergency which was granted on October 3, 2016, today by the press release 516/16 for the municipalities of Comala and Cuauhtemoc, State of Colima , for the volcanic eruption on September 30, 2016.
The abnormal situation created by this natural phenomenon has decreased to acceptable levels and responsiveness of the state government was strengthened by the support given by the Government of the Republic, by providing timely care to the population.

Colima eruption update – a flight yesterday showed the dome to be cooling with the effusion rate having dropped considerably. Frequent small explosions have resumed as the dominant activity.

Karymsky , Kamchatka :

54.05 N, 159.44 E;
Elevation 4874 ft (1486 m)
Aviation Color Code is ORANGE

A moderate gas-steam activity of the volcano continues. Ash explosions up to 19,700 ft (6 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft.

A moderate gas-steam activity of the volcano continues. According to satellite data by KVERT, gas-steam plumes contained ash drifted about 390 km to the east and south-east from the volcano on 07-08 October; a weak thermal anomaly over the volcano was noted on 07 and 12 October.

Karymsky, the most active volcano of Kamchatka’s eastern volcanic zone, is a symmetrical stratovolcano constructed within a 5-km-wide caldera that formed during the early Holocene. The caldera cuts the south side of the Pleistocene Dvor volcano and is located outside the north margin of the large mid-Pleistocene Polovinka caldera, which contains the smaller Akademia Nauk and Odnoboky calderas. Most seismicity preceding Karymsky eruptions originated beneath Akademia Nauk caldera, located immediately south.

 

karymsky

The caldera enclosing Karymsky formed about 7600-7700 radiocarbon years ago; construction of the stratovolcano began about 2000 years later. The latest eruptive period began about 500 years ago, following a 2300-year quiescence. Much of the cone is mantled by lava flows less than 200 years old. Historical eruptions have been vulcanian or vulcanian-strombolian with moderate explosive activity and occasional lava flows from the summit crater.
