White Island (New Zealand): (10 Mar) GNS volcanologists performed two observation flights over the volcano to observe and measure gas emissions over the past week.
An abundant amount of steam and gas emissions at a temperature of about 240 °C has been emitted from the Main Crater floor during the gas flight on 9 March. To compare with previous temperature analysis, it used to be detected more than 600 °C in the past. An increasingly larger gas plume could be seen rising also from the mainland on 5 March, observed by surveillance cameras, as well. Although gas fluxes have increased to the previous measurements, they still remain within the usual range for the volcano.

Heavy rainfall over the past month caused the Crater Lake levels to rise. As a result, some fumaroles are now under water leading to geysering and bubbling. No signs of volcanic ash in the plume or other eruptive activity were observed during the recent flights.
Both alert levels, the Aviation Color Code and the Volcanic Alert Level remain at Yellow and Level 2.


Tanaga (Aleutian Islands): (10 Mar) The seismic activity continues to be elevated over the past 48 hours, a typical sign of magma pushing its way towards the surface.
If the activity will persist in the increasing trend, this would be a potential tell-tale clue for an impending eruption. The largest earthquake over the past 24 hours was measured to be M 3.9 so far.

The seismic activity is also elevated at Takawangha volcano, which is about 8 km (5 miles) east of Tanaga on Tanaga Island. If an eruption were to occur, it is uncertain at this stage if it would come either from Tanaga or Takawangha.
To conclude, the AVO observatory raised the Volcanic Alert Level to Orange.


Takawangha (Tanaga Island, Aleutian Islands, Alaska): (10 Mar) The seismic activity continues to be elevated over the past 48 hours, a typical sign of magma pushing its way towards the surface.
If the activity will persist in the increasing trend, this would be a potential tell-tale clue for an impending eruption. The largest earthquake over the past 24 hours was measured to be M 3.9 under the Tanaga volcano so far.

Popocatépetl (Central Mexico): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 20000 ft (6100 m) altitude or flight level 200 .
The full report is as follows: LGT VA EMS OBS to 20000 ft (6100 m)

Fuego (Guatemala): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 .
The full report is as follows: LGHT VA OBSD to 15000 ft (4600 m)

Nevado del Ruiz (Colombia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 21000 ft (6400 m) altitude or flight level 210 .
The full report is as follows: VA EMS OBS to 21000 ft (6400 m)

Sangay (Ecuador): (9 Mar) Over the past week, explsoive activity has dominated at Sangay volcano. Dispite intermittent thick cloud cover, ash and gas plumes were observed on five of the last seven days.
The erupted plumes of ash and gas ranged in height between 560 m - 1000 m above the crater and leaned north, northwest, southwest and southeast.

The last observation of effusive activity (lava flow) was recorded on March 2.
Rainfall occurred on all but one day. This is significant as Sangay is prone to secondary lahars, which are formed when volcanic material mixes with water to form volcanic mud flows, which at Sangay flow down river pathways, notably the Volcan and the Upano.


Sabancaya (Peru): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 24000 ft (7300 m) altitude or flight level 240 and is moving at 20 kts in W direction.
The full report is as follows: INTERMITTENT EMISSIONS to 24000 ft (7300 m)
