Abstract

A silent and periodic earthquake trigger Large earthquakes that hit places such as Japan seem to be preceded by subtle and silent deformation. Uchida et al. show that these “slow-slip events” are quasi-periodic in the megathrust zone in Japan. Slow-slip events occurred every 1 to 6 years and frequently were correlated with large earthquakes, including the great 2011 Tohoku-oki earthquake. The quasi-periodic behavior stretches back to at least 1930 and provides an important constraint for seismic hazard assessment in the region. Science , this issue p. 488
