A submarine eruption that began on May 8, 2026, continues in the central Bismarck Sea, about 130 km (81 miles) southeast of Manus Island, Papua New Guinea. The eruption revealed a previously unmapped underwater volcano, now provisionally named Titan Ridge Volcano, in a remote and tectonically active area of the Pacific Ocean.

Explosive activity at Sheveluch volcano on the Kamchatka Peninsula, Russia, produced a volcanic ash plume rising to approximately 10.4 km (34 000 feet) altitude at 11:20 UTC on March 16, 2026, drifting east across the North Pacific. Satellite imagery from Himawari-9 detected the ash cloud moving east at around 110 km/h (70 mph). The Aviation Color Code remains at Orange.

Prolonged rainfall and cross-border inflows have triggered a state of emergency across northeastern Greece, where severe flooding along the Evros River in February 2026 submerged tens of thousands of acres of farmland and destroyed wheat, barley, lentil, and alfalfa crops. No fatalities have been confirmed, but authorities warn of extensive economic losses for the region’s farm sector.
