Representative figure

Twelve schematic deep-earthquake fault planes with arrows and ellipses marking inferred rupture directions and subevents beneath northwestern Japan. — Smaller events generally rupture faster and larger multi-subevent events more slowly; the duration–moment slope is about 0.26 and rupture lengths are 8.6–30.9 km.
