Earthquake collapses Kumomoto castle walls

Tremors from today's 7.1 magnitude earthquake caused historic walls at the 17th century-built Kumamoto castle to tumble. It isn't the first time the castle has succumbed to an earthquake, when a 7.3 magnitude quake hit the region in 2016, parts of the 400-year-old castle were also damaged when turrets and curved walls collapsed.
