According to IRD, during 27 May-3 June nearly continuous gas, vapor, and ash emissions at Tungurahua sent plumes 1.5-2.5 km above the crater and deposited ash on the volcano's flanks. During the night of 29 May, low-intensity Strombolian activity was observed. After 30 May, more intense ash-rich emissions occurred. Read all- More about Tungurahua volcano

Due to an increase in volcanic and seismic activity at Shiveluch, KVERT raised the Concern Color Code from Yellow ("volcano is restless") to Orange ("volcano is in eruption or eruption may occur at any time"). On 1 June at 1616 a short-lived explosive eruption produced an ash-and-gas plume to a height of 3 km above the lava dome. The plume was visible from Klyuchi town, 46 km from Shiveluch.

An increase in volcanic tremor at Kliuchevskoi led KVERT to raise the Concern Color Code from Green ("volcano is in quiet, "dormant" state") to Yellow ("volcano is restless") on 31 May. During most of the report week (24-31 May) seismicity was near background levels. Weak shallow earthquakes, other earthquakes ~30 km under the volcano, and episodes of weak spasmodic tremor were registered. Read all- More about Klyuchevskoy volcano

The Air Force Weather Agency reported that plumes were visible on satellite imagery emanating from Kikai during 24-28 May. The thin plumes drifted to the S on the 24th, SE on the 25th and 26th, S on the 27th, and E on the 28th. The plumes were estimated to be lower than 3 km a.s.l. Read all- More about Kikai volcano

On 27 and 28 May, AVO recorded anomalous seismicity at Great Sitkin. The seismicity consisted of two periods of seismic tremor on 27 May (lasting for 20 and 55 minutes) and two earthquake swarms on 28 May (beginning at 0406 and 1328). The earthquake swarms each began with a relatively large event (ML (local magnitude) 2.2 and ML 4.3) followed by tens to hundreds of smaller aftershocks, most located 5-6 km SE of the crater at depths of 0-5 km.

During 24-31 May, the level of volcanism at Soufrière Hills decreased in comparison to the previous week. The summit region of the active lava dome was broad and blocky in appearance. Lava-dome growth appeared to have become concentrated on the SE, leading to rockfalls and small pyroclastic flows down the flank. Read all- More about Soufriere Hills volcano

Volcanic tremor began to increase at San Cristóbal on 28 May, reaching a peak around noon the next day. The summit of the volcano was not visible, but satellite imagery from the Centro de Vigilancia de Ceniza Volcánica revealed that ash was emitted from the volcano. After the 29th, the amount of tremor decreased. Read all- More about San Cristobal volcano

Three main surface lava flows were visible at Kilauea during 29 May-2 June. The front of one flow was ~1.8 km from the coast. As of 2 June fires continued to burn that were ignited by a lava flow that began on 12 May. Read all- More about Kilauea volcano
Wed, 29 May 2002, 06:00
During 24-31 May, seismicity was above background levels at Karymsky, with ~10 earthquakes occurring per hour. The character of seismicity suggested that weak ash-and-gas explosions and gas blow-outs had probably occurred. Thermal anomalies were visible on satellite imagery, but ash was not.

During 22 April-26 May, small steam plumes rose 50-500 m above Karangetang's main crater and 10- to 25-m-high "red reflections" were visible above the crater at night. An ash explosion on 12 May at 1116 rose 750 m above the crater and drifted E over the sea. The eruption was followed by lava avalanches that traveled S down the Batu Awang river, and E down the Kahetang river to a maximum run-out distance of ~500 m. Read all- More about Karangetang volcano

During late May, volcanic and seismic activity were low at Etna. Volcanism consisted of gas emissions from Northeast, Voragine, and Bocca Nuova craters. Also, several small new fumaroles formed on the lower SE flank of Southeast Crater during about 26 May to 2 June. Read all- More about Etna volcano

The Rabaul Volcanological Observatory stated that the Strombolian eruption from Manam's S crater on 20 May ceased on the same day at about 1400. After that, activity consisted of forceful ash emissions in moderate volumes. The decline in activity led to the reduction in Alert Level from 2 ("eruption expected within weeks to months") to 1 ("non-threatening, background level"). Read all- More about Manam volcano

According to the Universidad de Colima, as of 27 May strong volcanic tremor continued at Colima, and small explosions and lava avalanches occurred. Also, seismicity was recorded that was associated with landslides and degassing. Incandescent lava avalanches traveled down the SSE flank of the volcano, with sudden increases in incandescence visible for several hours. Read all- More about Colima volcano

During 23-24 May, surface lava flows were visible on Kilauea's coastal flat. For several preceding days an intense swarm of small, shallow, long-period earthquakes occurred beneath Kilauea's caldera, at a rate of about one earthquake every 30 seconds. The swarm abruptly ended on 22 May. Read all- More about Kilauea volcano

During 17-24 May, seismicity was above background levels at Karymsky, with ~10 earthquakes occurring per hour. The character of seismicity suggested that weak ash-and-gas explosions, gas blow-outs, and debris avalanches occurred. Thermal anomalies were visible on satellite imagery, but ash was not.

During 14-21 May, emissions of gas, steam, and ash continued at Tungurahua. On 14 May an eruption produced a steam-and-ash plume that rose 1.5 km above the volcano. Read all- More about Tungurahua volcano

On 17 January 2002, during the eruption of Nyiragongo, all lava drained from the volcano's summit, leaving a 700-m-deep empty crater. In late April harmonic tremor began to be registered at two seismic stations on Nyiragongo's S flank, and increased irregularly in amplitude until mid-May. Anomalous clouds had been noticed above the crater twice since 1 May, but no incandescence had been visible at night. Read all- More about Nyiragongo volcano
