Early life and education

Latchman was born in Trinidad and Tobago around 1940. In 1972, shortly after completing her A-Levels, Latchman joined the University of the West Indies Seismic Research Centre as a technician.[1] In 1977 she started a part-time undergraduate degree in natural sciences.[2] She worked on the La Soufrière volcanic eruption with Keith Rowley in 1979 and worked at the Montserrat Volcano Observatory.[3] In 1982, after an earthquake swarm that occurred in the vicinity of Tobago, Latchman became interested in seismicity.[4][5] She worked with Frank Dale Morgan, a visiting academic from Massachusetts Institute of Technology who was working at the Seismic Research Centre.[1] Her early work considered the development of simple microprocessors that could convert the acoustic recordings of seismic events into digital signals that can be analysed on a computer.[6]

Research and career

Latchman was selected to take part in the International Seismological Centre in 1988 and spent two years analysing global seismicity.[7] She started a master's research project into the fault system of Tobago, and earned her degree in 1998. She joined the academic staff at the UWI in 1999 whilst working toward a doctorate in the Tobago and Earthquakes. She was eventually promoted to Director of the University of the West Indies Seismic Research Centre.[8]

She was responsible for the collection of seismic data from fifty stations throughout the Eastern Caribbean.[9] She has made efforts to communicate and better prepare people for seismic hazards in the West Indies.[10] Latchman called for local governments to include earthquake preparation in their policy work, including considering their infrastructure, medical equipment preparation and enforcement of building codes.[10][11]

Latchman retired from the UWI Seismic Research Centre in 2019.[3] She was visited by Keith Rowley, her former colleague and now Prime Minister of Trinidad and Tobago.[3] In 2019 Latchman was awarded the Caribbean Disaster Emergency Management Agency Council Award.[2]

Alongside her research, Latchman is committed to public engagement and outreach. She has been involved in a photographic exhibition that explored the volcanic activity of Saint Vincent and the Grenadines.[12] She routinely provided information about seismic activity to local and national newspapers.[13][14][15][16]
