In Vanuatu, Yasur activity is on the rise, with explosions in progress and emission of gases and / or volcanic ash observed. Villages near the volcano are likely to be impacted by ash falls and volcanic gases in an area NNW, current direction of the winds.
The volcanic alert remains at 2; the danger to life zone remains within the limits of danger zone A, approximately within 600 meters around the cone.
Over the past 24 hours at Popocatépetl, Cenapred has identified 125 exhalations, accompanied by gas, water vapor and little ash, as well as explosions, including two minor around 11:07 p.m. and 4:05 a.m., and a moderate, the 14.03 at 8.45 p.m. All the explosions were responsible for a plume of about 1,500 meters, dispersing to the northeast, and for ejecting incandescent materials at a medium distance from the crater.
Between these episodes, gas emissions, and slight amounts of ash are reported.
Tremor was recorded for 189 minutes.
The volcanic alert remains at Amarillo Fase 2.
AVO raised the alert level of the Shishaldin to Watch and the aviation code to orange this March 14 at 10:31 pm, following the observation on a high resolution satellite image of lava, and of what appears to be a new cone in the summit crater.
A weak tremor is also detected.
This increase is justified by a possible continuation of the activity, with little or no warning signs, resulting in lava flows outside the crater, lahars and ash clouds at low altitude.
Strombolian activity continues at Klyuchevskoy on March 15, with an ash explosion reaching 5,500 meters asl. The ash and gas cloud drifted 170 km towards the ENE.
The aviation code remains orange, due to possible ash explosion between 5,000 and 7,000 meters asl. anytime

The seismic swarm that started on March 12 northeast of Grindavík on the Reykjanes Peninsula is still in progress, but the intensity of the swarm has decreased since the start.
Many minor earthquakes are still detected in the region. At the start of the swarm, an M5.2 earthquake occurred approximately 5 km NE of Grindavík. During the first day of the swarm, eight more earthquakes above M3.0 were detected. Uplift is no longer observed in the area, which is likely due to the cessation of the influx of magma. The phase of uncertainty declared by the Civil Protection is still in force.
At 05:55, an M3.2 earthquake was detected just north of Herðubreið. More than 100 earthquakes have been located there since yesterday. About a week ago, a hundred earthquakes were also located there. Seismic swarms are common in this area, the last time an earthquake above M3.0 was detected in a similar area in November 2019.
