Tectonic setting: Subduction zone / Oceanic crust (< 15 km)
The Qualibou caldera on the SW side of St. Lucia provides the setting for the Pitons, two steep-sided pre-caldera lava domes that form one of the scenic highlights of the West Indies. The 3.5 x 5 km caldera formed about 32-39,000 years ago in conjunction with the eruption of the Choiseul Tuff. A larger depression has been interpreted to have formed by edifice collapse, and bathymetry has identifieβ¦

Current GOES X-ray flux class
Solar wind speed and magnetic field strength indicate current space weather activity. Elevated or storm-level readings can disrupt satellites, GPS accuracy, and power grids. This is a planetary-scale signal, not specific to this location β typical quiet conditions run under 400 km/s wind speed and under 5 nT magnetic field.
