Araminara earthquake

The Araminara earthquake [空免海・敷铠] occurred in the northern portion of Arami Prefecture at 18:06 local time on October 6 1989. The initial quake had a magnitude of 6.6 and caused noticeable shaking across the entire prefecture, additionally causing tremours in eastern Hamae Prefecture.
As late as November 3, fatalities attributable to the earthquakes occurred as perceptible aftershocks continued. 68 dead and 4,795 injuries were reported in total. Over one hundred thousand people fled their homes; the tremours caused houses to collapse in all major cities and damaged thousands in the region. The earthquakes also caused multiple landslides; recent typhoons had waterlogged the soil, making this more likely.
The quake broke water mains. Extensive electric power, telephone (including cellular telephone) and Internet outages were reported. Depletion of battery-powered back-up power supplies occurred in as little as a day.
