La Réunion , Piton de la Fournaise :

Activity Bulletin from Monday, March 4, 2019 to 17:00 (local time).

The eruptive activity that resumed on February 19, 2019 at Piton de la Fournaise around 7:10 pm local time continues. Despite slight fluctuations in intensity and relative stability since February 25, there has been an upward trend in recent days (Figure 1).

– Over the last 36 hours, 3 superficial volcano-tectonic earthquakes (above sea level) have been recorded.
– After a deflation of the building related to the transfer of magma that occurred on 18/02/2019, the summit area does not show any particular deformation signals.
– The CO2 concentrations in the near-field soil (cottage volcano area) remain high.

– At 10:30 this morning (06:30 UTC), the platform MIROVA (University of Turin) estimated from satellite data (MODIS), a flow of lava emitted 7.5 m3 / s. During the last 7 all the estimations made by this same platform remained between 0 and 10 m3 / s. Note that low values (or zero values) are recorded when cloud cover does not allow acquisition.

Alert level: Alert 2-2.

Chile , Nevados de Chillan :

Nuble Region, Nevados Volcano of Chillan, 04 March 2019, 15:50 local time (mainland Chile).

The National Geological and Mining Service of Chile (Sernageomin) publishes the following PRELIMINARY information, obtained from monitoring equipment of the National Volcanic Monitoring Network (RNVV), processed and analyzed at the Volcanological Observatory of the Southern Andes (OVDAS) :

Yesterday, Monday 04 March 2019 at 14:40 local time (17:40 UTC), monitoring stations installed near the volcano Nevados de Chillan recorded an earthquake associated with the fracturing of rocks inside the volcanic building (Volcano  – tectonic Type ).

The location of the earthquake after its analysis is:

TIME OF ORIGIN: 14h40 Local time (17h40 UTC)
LATITUDE: 36.914 ° S
LONGITUDE: 71.408 ° W
DEPTH: 3.9 KM
LOCAL MAGNITUDE: 3.0 ML

OBSERVATIONS:
At the time of this report, no other abnormal post-event signals were recorded. Nor was there any significant change in surface activity associated with the occurrence of this earthquake.
The level of volcanic technical alert remains at the level: ORANGE.

Sernageomin continues online monitoring and will inform in a timely manner about any changes observed.

Peru , Sabancaya :

An average of 17 Explosions / day was recorded. The activity associated with fluid movements (long period type) continues to predominate. On the other hand, earthquakes associated with the rise of magma (hybrid types) remain very few and low energy. 
The columns of gas and eruptive ash reached a maximum height of about 2700 m above the crater. The dispersion of these materials occurred within a radius of about 20 km, mainly to the northwest and southwest.

The GNSS-SBSE station, which measures volcanic deformation, has not detected any significant changes. 
Five thermal anomalies were recorded according to the MIROVA system, with values between 1 and 20 MW of PRV (Radiated Volcano Energy).

In general, eruptive activity maintains moderate levels. No significant changes are expected in the coming days.

Indonesia , Anak Krakatau :

Level of activity at level III (SIAGA) since December 27, 2018. The volcanic activity of the Anak Krakatau volcano (155 m altitude) has increased since June 18, 2018.

Since yesterday and until this morning, the volcano was visible until it was covered with fog. The winds were weak and oriented to the east. Crater smoke is not observed.

Through the seismographs, on March 4, 2019, it was recorded:
1 earthquake emission
10 deep volcanic earthquakes
1 local tectonic earthquake
Tremor continuous amplitude 1 – 2 mm, dominant value 1 mm.

Recommendation:
People / tourists are not allowed to approach the crater within 5 km.

VONA:
The latest code VONA received the color code ORANGE, published on 23 February 2019 at 17:33 WIB, relating to an eruption with a height of 500 m from the column of ashes. The magnitude of the earthquake was 25 mm and its duration was 271 seconds.
