The strongest shaking occurred in the city of Fukui, where it was recorded as 6 (equivalent to the current 7) on the Japan Meteorological Agency seismic intensity scale. The shock occurred near the town of Maruoka.[6]

Geology

This earthquake was caused by a strike-slip fault that was unknown until this earthquake. The fault stretches from Kanazu to Fukui,[7] 25 km (16 mi) long, and was later named the "Fukui Earthquake Fault". Shaking was felt as far as Mito in the east, and Saga in the west.

Damage

Damage was most reported in the Fukui plain, where the building collapse rate was more than 60%, since shaking became larger due to it being an alluvial plain, and many of the buildings were just built after the war and a little unstable.

At the time many people were cooking so after the earthquake many fires spread. Since the roads and the waterworks were damaged it took 5 days to put out the fires and so the fires caused devastating damage.

Even though the Daiwa Department Store collapsed, the Fukui Bank building right next to it had no significant damage. It is thought to have been because the Fukui Bank building had about 500 deep foundation pipes 10 meters deep in the ground.

Almost all of the farmers' houses in the epicenter area collapsed, but most of the farmers were outside so there were not many casualties.

Casualties

At the time, it was the deadliest earthquake after the Pacific War (now superseded by the Great Hanshin earthquake and the Tōhoku earthquake and tsunami). This earthquake killed 3769 people, mainly in Sakai City (then part of Fukui City), where the death rate was more than 1%.

Influence
gollark: The money generally comes from Primary Apionode 4124, since APIONET took over the financial system.
gollark: If you reduce government participation more stuff will probably be run by market systems and people/companies interacting directly, but that generally provides more choice than governments.
gollark: Idea: pay politicians more money so lobbying will be more expensive per unit politician.
gollark: Small companies can band together to lobby for things!
gollark: Well, you don't want a government which entirely ignores large companies or also small companies.
