MVO Weekly Report for the Period 9 to 16 May 2014 Activity at the Soufrière Hills Volcano remains low. The seismic network recorded one rockfall this week. Sulphur-dioxide measurements during the reporting period gave an average flux of 442 tonnes/day with a maximum of 636 and a minimum of 213 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. Residents of Montserrat might have felt an earthquake just after 7 am today. This was not from the volcano but from a magnitude 6.0 earthquake about 200 km east of Montserrat. 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). This report along with additional information on the Soufrière Hills Volcano and the Hazard Level System can be found at the MVO website: mvo.ms.
