Can storms prevent nasty earthquakes? That’s the suggestion of study showing that typhoons can trigger benign, “slow” quakes that ease the stress between tectonic plates. Beneath Taiwan, a tectonic plate is diving under its neighbouring plate at one of the world’s fastest rates. “You can almost watch them,” says study co-author Alan Linde of the Carnegie Institution in Washington DC. Yet the island has had fewer big rumbles than you’d expect from such movement. One explanation is that Taiwan undergoes slow earthquakes, in which crustal faults slip over hours or days, rather than seconds,
