The 40 pages that link to 2011 Tōhoku earthquake and tsunami, each with the reason it gives.

• TsunamiBroader topic: Its flooding exceeded defenses in some places and triggered the Fukushima nuclear accident.

• EarthquakeBroader topic: Its cascading effects exposed limits in coastal defenses and infrastructure planning.

• Megathrust earthquakeBroader topic: It showed that rupture can extend into shallow megathrust regions thought to slip less.

• Critical infrastructureBroader topic: The disaster exposed the consequences of physical hazards striking multiple essential systems.

• Japan TrenchBroader topic: It demonstrated that shallow trench sediments can participate in giant ruptures.

• Japanese archipelagoBroader topic: It showed how offshore plate boundaries can affect the whole archipelago.

• Tsunami warning systemBroader topic: The disaster showed that even advanced systems can underestimate tsunami height and impact.

• Okhotsk PlateBroader topic: It ruptured the Japan Trench boundary where the Pacific Plate subducts beneath the Okhotsk Plate.

• AftershockBroader topic: Its aftershock sequence included powerful events that complicated response and recovery.

• North PacificBroader topic: The disaster demonstrates the tsunami hazard along the western North Pacific.

• Japanese island arcBroader topic: The disaster showed how strain on the Japan Trench can produce destructive megathrust earthquakes and tsunamis.

• DisasterBroader topic: The cascading event included a nuclear accident and prolonged displacement.

• Sanriku CoastBroader topic: The disaster transformed Sanriku communities and prompted extensive rebuilding and coastal defenses.

• Interplate earthquakeBroader topic: Its unusually large slip near the trench demonstrated the potential of the Japan Trench boundary.

• MainshockBroader topic: Its rupture and aftershock sequence illustrate the scale of a major subduction-zone mainshock.
