The largest explosive volcanic eruption so far of 2026 is ongoing, producing vast amounts of pumice at the Titan Ridge Volcano. This is occurring underwater in Papua New Guinea, so the produced pumice are largely forming pumice rafts. Eruptive activity is currently occurring in two vents, and so far has generated a sustained eruption plume which has reached up to 28,000 feet above the ocean surface.
