A magnitude 5.7 earthquake hit Shizuoka Prefecture, leaving at least 22 people injured. Many got hurt after they fell on stairs while trying to escape buildings. Officials warned people to be on the lookout for mudslides and falling rocks. Bullet trains also ran at lower speeds as a safety step.
The meteorological agency put the magnitude at 5.7, while the US Geological Survey gave 5.5. The quake began about 40 kilometres (25 miles) below the surface in Shizuoka Prefecture, which is next to Aichi. Tokyo did not feel it.
What damage and injuries were seen?
Japanese TV showed smashed shop windows and glass spread across streets. A bookshop was left with piles of books that had been thrown from the shelves.
At least 22 people were hurt, local media said. Some fell on stairs as they tried to get out of buildings.
What has the weather agency warned?
Ayataka Ebita, an official of the Japan Meteorological Agency, told reporters that people should “be on the lookout for mudslides, falling rocks” and the effects of rain, AP says. The agency also asked people to brace for possible strong quakes in the week ahead, especially in the next two to three days.
Ebita said no clear change had been detected so far in the Nankai Trough plate, where scientists say a megaquake could one day strike.
The Shinkansen bullet trains ran at lower speeds in the areas hit, as a safety step. AP notes that quakes can sometimes damage the tracks the trains use.
Japan lies in a part of the world where earthquakes are common. Authorities often tell people to keep bottled water, food and batteries at home, plan to shelter under tables, and have comfortable walking shoes close by.
