Volcanology Watch: Mount Pelée, Martinique’s historically deadly volcano, is showing renewed unrest after decades of quiet, with the Martinique Volcanological and Seismological Observatory reporting 124 volcanic earthquakes in the week to 31 July (nearly triple the prior week) and 331 across July, alongside ongoing ground swelling near the summit; the alert level remains YELLOW, and scientists say the chance of an eruption in the short term is low, though it can’t be ruled out in the coming weeks to months. Regional Health Tech: Eastern Caribbean lab teams boosted their molecular diagnostics skills for emerging threats after a PAHO/WHO-backed workshop in Barbados, training participants (including from Martinique) on standardized testing for measles, leptospirosis and hantavirus, with a One Health approach linking human and animal surveillance. Marine Environment: A new report flags sargassum smothering Caribbean and Gulf coastlines, with scientists recording about 27 million metric tons in July and noting this year’s growth pattern is unusual—seaweed is appearing in large quantities locally rather than only arriving via currents. Sustainable Land & Water: Petite Martinique stakeholders began a sustainable land and soil management project aimed at restoring degraded landscapes and improving water security after Hurricane Beryl, funded by the Global Environment Facility and executed by UNEP, targeting 400 beneficiaries. Transboundary Plastic Pollution: Jamaica’s eastern coast is facing a plastic waste surge from foreign debris labeled in Spanish and French, with experts warning the problem is regional and needs cooperation beyond any single island.
