Since July 2000 AVO has detected a slight increase in the number of small earthquakes beneath Makushin. The earthquakes generally ranged in depth between 0 and 8 km and were too small to be felt by humans (M0-1.5). The seismic activity was not considered to be an immediate precursor to eruptive activity. Read all- More about Makushin volcano

During an excursion to Colima on 17 March by personnel from the Universidad de Colima a new crater was observed that was assumed to have been formed during the 22 February 2001 eruption. The crater was ~190,000 m3 in volume, making it the largest crater to form at Colima since the 1960s. On 26 May scientists discovered that a new lava dome that was ~150,000 m3 in volume had formed in the crater. Read all- More about Colima volcano

CENAPRED reported that on 31 May at 2136 a moderate-sized eruption began with the most intense phase lasting ~1 minute. Incandescent material traveled 2-3 km down the NE flank of the volcano. According to the Mexico City MWO a steam-and-ash cloud was observed rising up to 7.6 km a.s.l. and drifting to the W. Read all- More about Popocatépetl volcano
Wed, 30 May 2001, 06:00
During the week a large amount of high-frequency short-duration harmonic tremor occurred at Mayon. The tremor was associated with the intermittent descent of small lava avalanches and incandescent volcanic material down the Bonga Gully on the SE flank of the volcano. Moderate amounts of steam were observed rising from the summit crater where incandescence was occasionally observed. Read all- More about Mayon volcano

During the beginning of the week lava flowed down Pulama pali and entered the ocean at two areas. By 3 June there were few surface flows with most of the lava traveling in lava tubes and entering the ocean sporadically. On 3 June a pause in volcanic activity may have begun at about 0900 with slow deflation (~2.6 microradians) occurring at the tiltmeter closest to HVO. Read all- More about Kilauea volcano

According to the Italy's Volcanoes website, volcanic activity was at similar levels as it has been during the previous few weeks. Lava continued to travel from a vent on the NNE flank of the Southeast Crater cone, and mild, discontinuous Strombolian activity continued at the Southeast Crater's summit vent. Scientists determined that the lava effusion rate was approximately 5-10 cubic meters per second, which is high for Etna. Read all- More about Etna volcano

The Washington VAAC reported that Masaya may have erupted on 23 May at ~1300. Ground observations from the capital city of Managua, 20 km NW of the volcano, indicated that there was a reduction in visibility to the SE of the city due to volcanic "smoke" and steam. The presence of the ash cloud could not be confirmed on satellite imagery due to thunderstorms in the area. Read all- More about Masaya volcano

MVO reported that during 18-25 May volcanic activity increased in comparison to the previous week. The main increase in activity occurred during 19 to 21 May when many large long-period and hybrid earthquakes were recorded. Low-level convective ash clouds generated during this increase in activity rose less than 2 km a.s.l. Read all- More about Soufriere Hills volcano

On 22 May at 0209 an explosive eruption produced a mushroom-shaped ash column that rose to a height of more than 10 km a.s.l. (preliminary reports stated ~20 km). The high-pressure system over N Kamchatka caused the plume to remain fairly stationary over the region as it spread out to cover an area of ~50,000 km2. Read all- More about Shiveluch volcano
Wed, 23 May 2001, 06:00
Small-to-moderate sized exhalations occurred during the week. Based on information from the Mexico City MWO, the Washington VAAC reported that an eruption occurred on 26 May at 1122 that sent a steam-and-ash plume up to ~7 km a.s.l. Read all- More about Popocatépetl volcano

During the week seismic activity was relatively low at Mayon and was associated with occasional rockfalls that descended to the SE down the Bonga Gully. In addition, moderate steaming occurred, incandescence was occasionally observed at the crater, and SO2 emission (up to 5,700 metric tons/day) was above the baseline value of 500 tons/day. On 28 May at 1036 the seismic network recorded a low-frequency volcanic earthquake that was inferred from seismic data to be associated with an ash puff. Read all- More about Mayon volcano

The tilt event that began on 20 May ended the following day and HVO reported that the precursory deflation, remarkably rapid inflation of 10-11 microradians in one hour, and then the slow relaxation of the summit presumably recorded a pulse of magma supplied to the summit reservoir complex. The pulse was then transferred to the Pu`u `O`o area where it is currently stored. Lava continued to flow into the ocean at the SE corner of the lava flow field. Read all- More about Kilauea volcano
