Volcano Watch (Martinique): Mount Pelée is showing renewed unrest after the observatory logged 124 volcanic earthquakes between July 24 and July 31—nearly triple the prior week—plus ongoing ground swelling near the summit. Scientists stress an eruption is not considered imminent, but say a change over weeks to months can’t be ruled out. Earthquake (Eastern Caribbean): A 4.4 magnitude, shallow quake struck about 45 km east of Castries, with light tremors felt across Saint Lucia, Martinique, and St Vincent and the Grenadines; no damage or injuries were reported. Marine Health & Tourism (Caribbean/Gulf): A new surge of sargassum is blanketing coastlines, with about 27 million metric tons recorded in July across the Atlantic, Caribbean, and Gulf of Mexico. Researchers say this year’s growth in the region is “not normal,” and may be linked to warming waters, runoff, and changing winds and currents. Public Health Lab Capacity (Eastern Caribbean): PAHO/WHO and partners trained lab professionals in molecular diagnostics for diseases including measles, leptospirosis, and hantavirus, using a One Health approach to strengthen epidemic preparedness.
