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.

• HonshuRelated: The disaster prompted major reconstruction and changed risk planning across Honshu.

• Coastal floodingRelated: The tsunami inundated coastal settlements on a scale beyond ordinary storm flooding.

• Philippine Sea PlateCompared with: Unlike the Nankai megathrust, this event occurred where the Pacific Plate subducts beneath Japan.

• 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.

• Indo-Australian plateCompared with: It offers a comparison with a similarly large megathrust rupture on a different plate boundary.

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

• Tōhoku regionRelated: The disaster devastated coastal communities and reshaped the region’s recovery priorities.

• 1960 Valdivia earthquakeCompared with: It offers a modern comparison for megathrust rupture, tsunami destruction, and disaster response.

• Tokyo BayRelated: The earthquake produced measurable effects in Tokyo Bay despite its distance from the epicenter.

• 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.

• 2010 Haiti earthquakeCompared with: Its much larger magnitude and tsunami-driven impacts contrast with Haiti’s shallow, urban, land-based catastrophe.

• 1964 Alaska earthquakeCompared with: It offers a modern comparison for the cascading impacts of a giant subduction earthquake.

• 2010 Chile earthquakeCompared with: Its much larger tsunami exposed parallel challenges in warning systems and coastal protection.

• 2011 FIFA Women's World CupRelated: Japan’s team framed its championship as a source of hope after the disaster.

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

• Peru–Chile TrenchCompared with: It offers a comparison with another trench where megathrust rupture generated a devastating tsunami.

• Tōhoku ShinkansenRelated: The disaster halted Tōhoku Shinkansen services and prompted extensive inspections and repairs.

• 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.

• Heisei eraBroader topic: The disaster and ensuing nuclear crisis marked Heisei’s final decade.

• Iwate PrefectureRelated: The tsunami devastated coastal communities in Iwate and transformed local recovery efforts.

• Ring of FireRelated: Japan's position atop four converging plates makes it a densely populated segment of the ring.

• Fukushima PrefectureRelated: The tsunami caused deaths and damage across Fukushima’s Pacific coast.

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

• SendaiRelated: The disaster caused severe damage and loss of life in Sendai, especially along its coast.

• Ibaraki PrefectureRelated: The disaster caused major damage and disruption along Ibaraki’s Pacific coast.

• Miyagi PrefectureRelated: Miyagi was among the prefectures most severely affected by the tsunami.

• Great Hanshin earthquakeCompared with: Its far greater magnitude and tsunami impacts contrast with Hanshin’s concentrated urban shaking.

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

• Fukushima nuclear accidentRelated: The earthquake shut down operating reactors; the tsunami disabled vital power and cooling systems.

• Homare SawaRelated: Japan’s World Cup victory later that year was widely framed as a source of encouragement after the disaster.

• 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.

• Shintaro IshiharaRelated: Ishihara’s description of the disaster as divine punishment drew widespread condemnation.

• HachinoheRelated: The tsunami damaged Hachinohe’s waterfront and disrupted port activity.
