Activity at the Soufrière Hills Volcano is low. Yesterday was the eighteenth anniversary of the start of surface activity at the Soufrière Hills Volcano on 18 July 1995.
The seismic network recorded six rockfalls and four volcano-tectonic this week.
Sulphur-dioxide measurements gave an average flux of 273 tonnes/day with a maximum of 392 and a minimum of 207 tonnes/day.
Pyroclastic flows can occur at any time without warning on any side of the volcano, including Gages from where they can travel rapidly into Plymouth. Tracks across the Belham valley are frequently destroyed or heavily modified by flash flooding or lahars, and caution should be exercised crossing the valley during and after rainfall.
The Hazard Level is 2. There is no access to Plymouth or the rest of Zone V. Zone C is open to pass-holders between 8 am and 4 pm every day: passes and an explanatory leaflet can be obtained from Salem police station. Maritime Zone W remains daytime transit only (boats may sail through the zone but must not stop).
