Soputan, Indonesie :


There was an eruption of Soputan in North Sulawesi 7 March 2015 at 17:30. The estimate of the height of the eruption column is quite difficult because the Soputan is usually in the fog. But for now it was estimated that the height of the column was reached 4500m above Soputan.

The eruptions issued a gray cloud of smoke. hot pyroclastic cloud to also observed mainly in the west at a distance of approximately 2500m from its point of origin. the increased volcanic activity of the Soputan was provided by the PVMBG local government at BPBDs & Airport. So far the seismic station in Aesoput still works and the seismograms show a constant tremor with an average amplitude of 20 mm.

So far the Soputan remained at the level of activity and alert III. Visitor / climber are encouraged not to move within 4 km from the summit of Mount Soputan with sector expansion westward as far as 6.5 km.

Popocatepetl, Mexique :

March 7 11:20:00 p.m. (March 7, 5:20:00 p.m. GMT)

In the last 24 hours the Popocatepetl volcano monitoring system recorded 146 exhalations accompanied by vapor emissions, gas and sometimes moderate amounts of fine ash. The largest occurred at 1:22 p.m., 6:48 p.m., 7:23 p.m., 7:39 p.m., 8:19 p.m..



This morning at 6:20 ha started a “train” of explosions which generated a plume of ash from 1-2 km altitude, that the winds were drifting to the southwest.
This train explosions decreased in amplitude from 8:41, when an earthquake volcanotectonic of preliminary magnitude M2 occurred. However, the exhalations continue at this report, with a tendency to decrease. Furthermore, was recorded 25 minutes of harmonic tremor. Ash falls were reported to Ecatzingo, and it is likely that this is happening in other villages in the area.
At the time of this report there is no visibility of the volcano.


CENAPRED urged do not approach the volcano crater and especially because of the danger of ballistic fragments falls as mentioned in the report.
Continuous monitoring of the activity is maintained. Besides the Ministry of Health, the Secretariat of National Defense, the Federal Police of the State, civil protection units, Morelos, Puebla, Mexico State, Mexico and the Federal District of Tlaxcala are on alert before the volcano.
The Semáforo of Alerta Volcánica of Popocatepetl is located in Amarillo Phase 2.

Soufrière Hills, Ile de Montserrat, Royaume Uni:

MVO Weekly Report for the Period 27 February to 6 March 2015.

Activity at the Soufrière Hills Volcano remains low.

The seismic network recorded one rockfall and two volcano-tectonic earthquakes this week.
Sulphur-dioxide measurements during the reporting period gave an average flux of 336 tonnes/day with a maximum of 642 and a minimum of 172 tonnes/day.

Pyroclastic flows can occur at any time without warning on any side of the volcano, including Gages from where they can travel rapidly into Plymouth. Tracks across the Belham valley are frequently destroyed or heavily modified by flash flooding or lahars, and caution should be exercised crossing the valley during and after rainfall.

The complex, dominantly andesitic Soufrière Hills volcano occupies the southern half of the island of Montserrat. The summit area consists primarily of a series of lava domes emplaced along an ESE-trending zone. The volcano is flanked to Pleistocene complexes to the north and south. English’s Crater, a 1-km-wide crater breached widely to the east by edifice collapse, was formed about 2000 years ago as a result of the youngest of several collapse events producing submarine debris-avalanche deposits.



Block-and-ash flow and surge deposits associated with dome growth predominate in flank deposits, including those from an eruption that likely preceded the 1632 AD settlement of the island, allowing cultivation on recently devegetated land to near the summit of the volcano. Non-eruptive seismic swarms occurred at 30-year intervals in the 20th century, but no historical eruptions were recorded on Montserrat until 1995. Long-term small-to-moderate ash eruptions beginning in that year were later accompanied by lava-dome growth and pyroclastic flows that forced evacuation of the southern half of the island and ultimately destroyed the capital city of Plymouth, causing major social and economic disruption.
