Earthquake Strikesthe Coast of Fukushima Prefecture

By: SiliconExpert on February 23rd, 2021

On the evening of the Saturday, February 13, 2021,  a large earthquake shook a broad area across eastern Japan with its epicenter off the coast of Fukushima Prefecture.  According to the National Meteorological Agency, the 7.1 magnitude earthquake struck the country’s east coast at 11:07 p.m.  With no casualties reported, the earthquake still left 100 injured across Fukushima and Miyagi prefectures.

In addition to injuries, the earthquake also left nearly a million households without power across the Fukushima region.  It alsoforced the closure of roads and the suspension of train services. While rattled residents did brace for aftershocks, but a landslide cut off a chunk of the main artery through Fukushima Prefecture.

This is not the first earthquake to impact Fukushima Prefecture.  In 2011, a massive earthquake and tsunami killed thousands and caused a meltdown at the local nuclear plant.
