The MVO reported that during 23 February to 2 March activity at the Soufrière Hills volcano increased with a marked change in the character of the seismicity, a change in the direction of lava dome growth, and moderate levels of pyroclastic flow activity. An unusually large number of hybrid earthquakes (388) were recorded during the week. On 24 February dome growth was concentrated on the NE side of the lava dome, but the next day the area of growth changed to the S side of the dome. Read all- More about Soufriere Hills volcano

PHIVOLCS reported that during 28 February to 6 March, 15 to 50 low-frequency earthquakes were recorded daily. An average of 1,855 metric tons per day (t/d) of SO2 was recorded during the previous week, which was significantly above the baseline value of 500 t/d. A slight inflationary trend was detected at the volcano's edifice, no incandescence was observed at the crater, and weak-to-moderate steaming was occasionally seen. Read all- More about Mayon volcano

Based on satellite imagery and pilot reports, the Tokyo VAAC reported that an eruption may have occurred at Kliuchevskoi. The ash cloud produced from the eruption rose to a height of ~9.5 km and was visible on GMS-5 imagery at 1532 on 4 March. By 1832 the same day the ash cloud was no longer visible on satellite imagery. Read all- More about Klyuchevskoy volcano

The AVO reported that no further eruptive activity was observed or detected at Cleveland since the 19 February eruption. During 19 February to 2 March, GOES-10 imagery showed a weak thermal anomaly that was probably related to hot material deposited on the flanks of the volcano on the 19th. Photographs taken a few days after the eruption showed significant accumulation of spatter and lava blocks high on the steep flanks of the volcano; occasional avalanching of this debris may produce small, localized ash plumes.

The KVERT reported that during 25-27 February there was an increase in seismic activity. Two- and three-minute-long series of shallow earthquakes were registered and followed by weak volcanic tremor. These outbursts may have corresponded to weak ash-and-gas explosions that reached a height of ~2 km above the crater. Read all- More about Shiveluch volcano

A light gray plume of fine ash rose ~2 km above the MH vent and drifted towards the mainland. Fine ash was deposited on and near White Island, but only an acid aerosol cloud reached the mainland near the town of Matata. Read all- More about White Island volcano

The IGNS reported that an episode of strong volcanic tremor was recorded at Ruapehu. The tremor episode peaked on 16 February and was the strongest tremor recorded since the 1996 eruptions, but direct observations of the crater revealed a lack of unusual activity. By approximately 23 February the tremor had declined to background levels. Read all- More about Ruapehu volcano

Visual observations by VSI personnel during 12-17 February revealed that volcanic activity remained low at Lokon, with steam plumes rising 200-350 m above the crater rim. Seismic data were not available because the seismograph on the volcano was broken. The volcano remained at Alert Level 3 (on a scale of 1-4). Read all- More about Lokon-Empung volcano

In the wake of earlier concern about renewed volcanic activity at Kelut, the VSI reported that during 12-17 February the temperature of Kelut's crater lake decreased and its pH increased. The temperature decreased to 47.5°C from a range of 50.1 °C to 51 °C, measured during 29 January to 7 February. The pH of the water increased to 5.3 from 5, measured on 7 February.

The Volcanological Observatory of Colima University reported that a moderate explosion occurred at 0532 on 22 February. After reviewing video footage of the eruption, the observatory concluded that the ash cloud produced from the eruption rose ~2 km above the volcano at an average velocity of 200 meters/second (m/s). Incandescent ballistics were hurled up to 3 km away from the volcano at a rate of ~100 m/s and landed on the NE and SW flanks of the volcano, and to a lesser extent on the N flank.
