As part of the first-ever Montserrat Science Week, MVO held an Open Day on Thursday 19 January. MVO Open Day showcased MVO’s monitoring work with activities including:

• Tour of the Operations Room with interactive seismic activities
• Hands-on demonstrations of deformation monitoring, gas monitoring, and safety equipment
• Volcanic rocks and artefacts

Students from Brades, Lookout and St. Augustine’s Primary Schools, Lighthouse Community Academy, and Montserrat Secondary School came to MVO throughout the day to get hands on experience from the special demonstrations. Members of the general public came later in the afternoon for the event. Students were very enthusiastic and they particularly enjoyed the tour of the operations room, where they jumped up and down to simulate an earthquake and afterwards viewed their seismic signals.

Also as part of Montserrat Science Week, MVO staff hosted Children’s Fun Day. The event was well-attended and a great time was had by all. MVO concluded its involvement in Montserrat Science Week with the guided Geology Boat Trip from Little Bay to Plymouth, led by MVO Director Dr. Paul Cole.

Other Montserrat Science Week events included public presentations about Montserrat’s sea turtles, the Mountain Chicken Project, and the Montserrat Reef Project as well as a guided forest hike led by James “Scriber” Daley.

MVO is currently hosting a workshop for instruction on post-processing of Global Positioning System (GPS) data. MVO uses GPS data to assess the inflation or deflation of the volcano by recording small changes in the position of GPS receivers across the island. Because ground movements are so small, it is important to have very precise and accurate data. By post-processing the data using this software, rather than calculating coordinates on-the-spot as hand-held GPS receivers do, MVO is much better able to constrain the locations of it GPS receivers.

Aimed towards both new users and those that wish to improve their skills, participants hail from different locations in the Caribbean and France. This workshop was organized by Dr. Henry Odbert of MVO and its lecturer is Prof. Tom Herring of Massachusetts Institute of Technology, a key developer of the software.

Drs. Henry Odbert and Adam Stinton are currently working on an ongoing research project to study the cooling of pyroclastic deposits in order to estimate how long they take to cool to ambient temperatures. They have found that the top surface of pyroclastic deposits cools within weeks, but that the inside can remain hot for a long period of time. This is important because hot pyroclastic deposits can be hazardous, with the potential to seriously burn or even cause small explosions when it comes into contact with water.

Temperatures at the top of pyroclastic deposits can be measured with a thermometer or remotely using a thermal infrared camera. Temperatures on the inside of deposits are not so easy to measure. In order to do so, a deep hole must be dug in order to access deep into the deposit - a process that can involve considerable work. Pictured below is a team of MVO scientists, staff, and volunteers recently digging such a trench at Trants in pyroclastic deposits from the 11 February 2010 dome collapse. Measurements from this excursion show that the deposits are still hot with a temperature of 125 C at a depth of 3 m (the deposit is approximately 12 m thick in this area). Temperature measurements have been made a number of times since the deposits were emplaced. Analyzing these measurements using a thermal conduction computer model suggests that it will take many years for the core of the deposit to reach ambient temperatures.

Dr. Vitchko Tsanev and Mr. Brian Jones from Cambridge University are visiting MVO this week to test, calibrate, and continue installation of the new Differential Optical Absorption Spectroscopy (DOAS) network. DOAS is used to measure the amount of sulphur dioxide (SO₂) coming out of the volcano.

DOAS is used for determining the amount of sulphur dioxide (SO₂) in a volcanic gas plume by measuring the intensity of ultraviolet light which has travelled through it. SO₂ absorbs light between 300 and 318 nanometres. The light that travels through SO₂ will be less in those wavelengths due to the absorption. The greater the absorption, the more SO₂ is present in the plume.

DOAS is the primary technique used by MVO to measure daily SO₂ flux rates, which are reported regularly in the Weekly Activity Reports. There are currently two active DOAS stations located at Broderick’s and Lover’s Lane, as indicated on the map. They are both located to the west of the volcano due to the prevailing east to west wind direction. Measurements are best taken when the sky is sunny and cloud-free, so that direct, rather than scattered, light is used. Additional spectrometers can be used as mobile units, able to be deployed to any accessible location suitable for taking measurements. This can be particularly useful if the permanent stations are covered in ash or if the plume is going in an unusual direction.

On 4 November 2011, NDPRAC decreased the Hazard Level from 3 to 2. This follows from an assessment which indicates that the threat of hazards (mainly pyroclastic flows and surges) in Zone C has reduced. It should be noted that the risk of death or injury from a pyroclastic flow increases markedly in the exclusion zone Zone V (which includes Plymouth and its suburbs) and that Zone V remains off-limits. The boundary between Zone C and V is marked by a pronounced gorge or ghaut at the end of Lovers' Lane, which becomes shallower westwards toward Sturge Park and there are signs indicating its location in several places. Crossing this boundary and entering the exclusion zone Zone V - without formal permission and associated safety measures - would expose an individual to considerably higher risk.

MVO and the NDPRAC are constantly responsive to the changing state of the volcano. There is currently NO evidence that the eruption has ended and it is quite possible that volcanic activity could increase markedly at any time. Any person entering Zone C should remain alert and be prepared to respond immediately should activity escalate. Any such escalation will be reported promptly on ZJB Radio Montserrat and sirens will be sounded.

This year at Alliouagana Festival of the Word, MVO presented the "Island of Fire" book and awarded this year's poetry competition winners.

"Island of Fire," the captioned photo book edited by MVO staffmembers, was showcased during the Writers' Corner. Dr. Paul Cole showed photographs from the book to the audience, explaining how the book presents unique views of the volcano and never-before-documented phenomena. Later in the afternoon, MVO awarded the cash prizes and certificates to the 1st, 2nd, and 3rd place of this year's "Volcano in my Backyard" poetry competition. After awards were given, the winners recited their poems. Students receiving Honourable Mentions were also recognized at the ceremony and a book containing this year's entries was presented to librarian Sonia Smith for public display at Montserrat Public Library. There were 140 entries in this year's competition, and the judging panel was impressed at the high quality of the students' work. To view winning entries, honourable mentions, and more, click here.
