The elongated, extensively eroded Tutuila Island in the center of the Samoan Islands consists of five Pliocene-to-Pleistocene volcanoes constructed along two or three rifts trending SSW-NNE. The Pago basaltic-to-andesitic shield volcano in the center of the 32-km-long island is truncated by an eroded, 9-km-wide caldera that encloses Pago Pago harbor on its west. The caldera is now partially filleβ¦

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.
