Seismic biomarkers in Japan Trench fault zone reveal history of large earthquakes

Researchers used a novel technique to study the faults in the Japan Trench, the subduction zone where the magnitude 9.1 Tohoku-Oki earthquake struck in 2011. Their findings reveal a long history of large earthquakes in this fault zone, where they found multiple faults with evidence of more than 10 meters of slip during large earthquakes.
