In the nutmeg plantations that the Dutch had carved from conquered land, in the colonial houses of Banda Neira, in the fishing villages that clung to the smaller islands, people felt the earth heave with a force later rated XI on the Modified Mercalli scale -- violent enough to destroy well-built structures, to crack the ground open, to make standing impossible. Then the shaking stopped. About fifteen minutes later, the sea arrived. Waves measuring up to eight meters crashed into Banda Neira, Saparua, Haruku, and Ceram, washing away villages, ships, and the people who had not fled to higher ground. At least sixty people died. It was the worst disaster to strike the Banda Islands since the Dutch themselves had arrived two centuries earlier, and it left a scientific puzzle that researchers are still arguing over today.

These tiny volcanic specks in the Banda Sea had been the world's sole source of nutmeg, and that distinction brought the full weight of European colonial violence. In 1621, the Dutch E...

It did not first withdraw -- the classic drawback that signals a subduction-zone megathrust earthquake, where the overriding plate snaps upward and...

The argument over the 1852 earthquake's source has played out across decades of academic papers, each team marshaling the same sparse colonial records toward opposite conclusions. Phil Cummins proposed a moment magnitude of 7.5 on a low-angle normal fault near the Banda Islands, ...

The Banda Sea sits within one of the most tectonically complex regions on Earth, where the Australian and Sunda plates grind together and the crust has fractured into a constellation of minor plates and microplates. The convergent boundary resembles an arch, and oceanic lithosphe...
