ebeko

A moderate gas-steam containing ash explosive activity of Ebeko volcano on 08-09 December, 2016.

According to the data by observers from Severo-Kurilsk (Paramushir Island, Northern Kuriles), gas-steam plumes containing small anount of ash rose up to 1.5 km a.s.l. and extended for about 6 km to the north from Ebeko volcano on 08-09 December. Satellite data by KVERT showed a weak thermal anomaly over the volcano on 08 December, but ash plumes were not detected on 08-09 December.

A moderate gas-steam with small anount of ash activity of the volcano continues. Ash explosions up to 16,400 ft (5 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft and airport of Severo-Kurilsk.

 

ebeko

The flat-topped summit of the central cone of Ebeko volcano, one of the most active in the Kuril Islands, occupies the northern end of Paramushir Island. Three summit craters located along a SSW-NNE line form Ebeko volcano proper, at the northern end of a complex of five volcanic cones. Blocky lava flows extend west from Ebeko and SE from the neighboring Nezametnyi cone. The eastern part of the southern crater contains strong solfataras and a large boiling spring. The central crater is filled by a lake about 20 m deep whose shores are lined with steaming solfataras; the northern crater lies across a narrow, low barrier from the central crater and contains a small, cold crescentic lake. Historical activity, recorded since the late-18th century, has been restricted to small-to-moderate explosive eruptions from the summit craters. Intense fumarolic activity occurs in the summit craters, on the outer flanks of the cone, and in lateral explosion craters.

Nishinoshima , Japan :

Island volcano monitoring system tested at Nishinoshima .

8 DECEMBER 2016. During the October cruise of KS16-16 a research team with members from the Kobe University Graduate School of Science, the University of Tokyo Earthquake Research Institute and the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) tested a newly-developed island volcano monitoring system in the seas around Nishinoshima, where eruptions have been continuing since November 2013.

The monitoring system uses a wave glider that can operate autonomously relying solely on wave power. The glider is equipped with cameras for visual observation of the volcano, a GPS wave gauge that can detect tsunami caused by volcanic collapse, and a gauge that checks for earthquakes and air vibrations by measuring sonic waves in the air and water. During the system’s test run around the island researchers were able to confirm that these features were functioning correctly.

In order to monitor in real time, they continuously transmitted data from the wave gauge and earthquake/air tremor gauge to a server on the mainland 1000km from Nishinoshima using satellite transmissions.

Based on this test run, the development stages of the island volcano monitoring system are almost complete, and the group plans to start preparing the system for practical use in monitoring Japan’s numerous island volcanoes

Turrialba, Costa Rica :

Activity report of the Turrialba volcano:
8 December 2016.

turrialba

After about 3 days of continuous ash emission, the volcano showed a decrease in its activity at the end of the morning with sporadic and low emissions during the afternoon. The few direct observations showed a plume not more than 200 m above the top of the volcano (~ 3500m above sea level). The prevailing winds are oriented to the south-west. There were no reports of ash falls.

INCREASE IN FUEGO VOLCANIC ACTIVITY

Type of activity: Vulcanienne
Morphology: Stratovolcan composite
Geographical location: 14 ° 28 ’54 ˝ Latitude N; 90 ° 52 ’54 ˝ Londitude W.
Height: 3,763ms nm.

A change in the eruptive structure of the Fuego volcano was generated last night, with an increase in the number of explosions, from 3 to 5 per hour, moderate and some strong, expelling abundant ashes reaching heights of 4,800 meters (15,748 feet ) to the west, and the south-west of the volcanic complex, for a distance of 12 kilometers. Ash deposits on the villages of Morelia, Hagia Sophia, Panimache I and II, El Porvenir and San Pedro Yepocapa are registered. During the evening, an incandescence was observed with avalanches of blocks coming from the crater that reach the vegetation.

This activity is accompanied by low and moderate explosion noises and shock waves, sometimes
This change of eruptive pattern maintains its tendency to increase in the next hours, so it is recommended to keep abreast of the evolution of the activity of the Fuego volcano.

Therefore, INSIVUMEH recommends:
To CONRED: to take the precautions it deems necessary because of the increased activity of the Fuego volcano.
At the Directorate General of Civil Aviation: It is recommended to take precautions with air traffic, because the column of ash reaches a maximum height of about 4,800 meters (15,748 feet) while moving towards the Southwest and  West.
To tourist agencies and tourists: The explosive activity of the Fuego volcano can generate ballistic falls on the « meseta », so it is recommended not to stay or camp in this area.
