The Nankai Trough just off southern Japan poses a severe seismic threat, with locked plates accumulating enormous stress. A new dataset from the Japan Coast Guard offers an unprecedentedly detailed look into the variability of this locking state over a ten-year period,

Temblors frequently strike around the world. These suggestions will help you prepare for the next quake that might rattle your town.

Off the southern coast of Japan, the Philippine Sea Plate lies underneath the Japanese mainland. The locked tectonic plates threaten to unleash a catastrophic megathrust earthquake, likely within the next few decades.

The Mendocino Triple Junction off the coast of Northern California is the point where three tectonic plates meet. A new study reveals at least five moving pieces deep below the Earth's surface make up this complex seismic region. (Image by S. Greg Panosian ...

For more than 15 years, UB geologist Margarete Jadamec has studied the Alaskan subduction zone, where two huge pieces of the Earth’s rigid outer layer — the North American Plate and the Pacific Plate — are converging. In this region, the Pacific ...

When tectonic plates move, they rarely do so smoothly. Sometimes they slide almost imperceptibly; at other times, stress is suddenly released—resulting in an earthquake. What exactly governs this behavior remains one of the key open questions in ...
