Volcanic and seismic activity were at low levels during 21-28 June at Soufrière Hills. Growth of the extruded lobe on the SE side of the lava dome appeared to have stagnated. The number of rockfalls decreased abruptly on the afternoon of 22 June, remained at low levels for the rest of the week, and declined to very low levels during the last 3 days of the report period.

Volcanic activity at Soufrière Hills during 14-21 June was slightly higher than it had been the previous week. Rockfall activity increased abruptly on the night of 14 June and remained at moderately high levels until the 18th, when it declined. The active lobe on the SE side of the lava dome continued to grow and was topped by a small, low-angle spine extruded towards the SE. Read allMontrer plus

Volcanic and seismic activity remained at low levels at Soufrière Hills during 7-14 June. The massive extrusive lobe on the SE side of the lava dome continued to grow steadily throughout the week, although there was a low level of rockfall and seismic activity. Minor rockfall activity occurred on the E flank of the dome, increasing slightly during the latter half of the week. Read allmer., 5 juin 2002, 06:00
The level of volcanism at Soufrière Hills was low during 31 May-7 June. During 31 May-4 June, the lava dome was seen clearly for the first time in several months. Since early April a large lobe had been extruded on the SE side of the dome's summit. Read allmer., 29 mai 2002, 06:00
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 allmer., 22 mai 2002, 06:00
During 17-24 May, the level of volcanism at Soufrière Hills remained similar to that in the previous week. Cloudy conditions obscured visual observations, but lava-dome growth appeared to be concentrated on the volcano's E flank. Numerous rockfalls and small pyroclastic flows traveled to the upper portions of the Tar River Valley. Read allmer., 15 mai 2002, 06:00
During 10-17 May, volcanic activity was generally higher than it had been the previous week. Lava-dome growth continued to be concentrated on the E flank. Rockfall, pyroclastic-flow, and long-period earthquake activity was relatively high during the first half of the report period, but declined slightly during 15-17 May. Read allmer., 8 mai 2002, 06:00
During 3-10 May, the level of volcanism at Soufrière Hills was generally lower at the beginning of the report period than it had been the previous week, but it increased during the 8th to 10th. Growth of the lava dome to the E continued to produce rockfalls and small pyroclastic flows down the E flank. Beginning on 8 May, activity increased and rockfalls and pyroclastic flows were concentrated on the dome's NE flank. Read allmer., 1 mai 2002, 06:00
Volcanism at Soufrière Hills during 26 April-3 May remained at high levels. The lava dome continued to grow on the E side of the dome complex. Numerous rockfalls and small pyroclastic flows occurred at the E face of the dome as a result of material spalling off of the active extrusion lobe. Read allmer., 24 avril 2002, 06:00
Volcanic activity at Soufrière Hills was at high levels during 19-26 April. The direction of lava-dome growth switched during the earlier part of the week, becoming focussed on the southeastern part of the dome complex. Rockfalls traveled down the SE flank of the dome almost continuously. Read allMontrer plus

During 12-19 April, the level of volcanism at Soufrière Hills slightly decreased in comparison to the previous week. Lava-dome growth was concentrated on the SE area of the dome complex, although small rockfalls occurred in other areas. The lava dome evolved from a large striated lobe at the beginning of the week, to a series of small spines by week's end. Read allmer., 10 avril 2002, 06:00
During 5-12 April, volcanism slightly decreased at Soufrière Hills in comparison to the previous week. Lava-dome growth over the entire summit region produced rockfalls that traveled predominately to the SE, E, and NE. Several pyroclastic flows traveled E for ~2 km down the Tar River Valley, reaching the sea. Read allmer., 3 avril 2002, 06:00
During 29 March-5 April, volcanism slightly decreased at Soufrière Hills in comparison to the previous week. Lava-dome growth over the entire summit region produced rockfalls that traveled predominately to the SE, E, and NE. Several pyroclastic flows traveled E ~2 km down the Tar River Valley, reaching the sea. Read allmer., 27 mars 2002, 06:00
During 23-29 March, the level of volcanism remained high at Soufrière Hills. Lava-dome growth continued to be focused to the E of the summit region, producing numerous rockfalls and small pyroclastic flows into the upper portions of the Tar River Valley. Minor amounts of rockfall debris from the NE flank of the dome spilled into the head of Tuit's Ghaut. Read allmer., 20 mars 2002, 06:00
The level of volcanic activity at Soufrière Hills remained high during 15-22 March. Lava-dome growth continued to be focused on the E side of the summit region. Throughout the report period large (50-70 m high), fast-growing, spines developed on the dome's summit. Read allmer., 13 mars 2002, 06:00
During 8-15 March, the level of volcanic activity at Soufrière Hills was higher than during the previous week. Activity began to increase on the 8th, remaining at elevated levels for the remainder of the report period. Lava-dome growth continued to be concentrated towards the E, sending rockfalls and small pyroclastic flows to the upper portions of the Tar River Valley. Read allmer., 6 mars 2002, 06:00
During 1-8 March, volcanism decreased at Soufrière Hills in comparison to the previous week. Lava-dome growth continued to be concentrated towards the E, sending rockfalls and small pyroclastic flows to the upper portions of the Tar River Valley. Incandescence was visible on the upper parts of the dome during the night. Read allmer., 27 févr. 2002, 06:00
The level of volcanism at Soufrière Hills during 22 February-1 March was higher than it had been in previous weeks. The continued growth of the lava dome towards the E led to almost continuous rockfalls and small pyroclastic flows that traveled to the upper portion of the Tar River Valley. During the week a large, steeply inclined spine was extruded on the summit of the dome. Read allmer., 20 févr. 2002, 06:00
During 15-22 February, volcanism was generally high at Soufrière Hills. Lava-dome growth continued to be focused on the E sector. Activity increased during the second half of the report period; near-continuous rockfalls and minor pyroclastic flows traveled down the volcano's E flank. Read allmer., 13 févr. 2002, 06:00
During 8-15 February volcanism at Soufrière Hills decreased slightly in comparison to the previous week. Lava-dome growth continued to be focussed towards the E and NE, producing numerous rockfalls and small pyroclastic flows in the upper portions of the Tar River Valley. Minor rockfalls of old inactive dome material traveled W to the upper portion of the Gages region. Read allmer., 6 févr. 2002, 06:00
During 1-8 February volcanism slightly increased at Soufrière Hills in comparison to the previous week. Lava-dome growth continued to be focused on the E and NE sides of the dome. The summit of the dome was blocky and massive, rather than covered with spines like it was during the previous week. Read all
