Pacific quakes and Taiwan supply strains
A magnitude-6.2 quake struck near Hihifo, Tonga early Monday and a separate 6.1 tremor rattled the South Pacific — both raise the risk of aftershocks and local disruption to regional logistics. At the same time Taiwan’s medical supply chains are being squeezed by the twin pressures of recent seismic activity and Middle East conflict, with National Taiwan University Hospital actively securing critical supplies as a precaution.

USGS located the Tonga epicenter at 15.498°S, 172.271°W and recorded the event at 2026-03-22 15:28:00 UTC at a focal depth of 79.7 km.
