Volv on Instagram: "Japan has activated its top earthquake warning for the first time, saying an 8.0+ “megaquake” could hit the Pacific coast in the coming days, with tsunamis possible from Hokkaido to Chiba. After Monday’s 7.5 quake injured 33 and forced 90,000 evacuations, residents were told to prepare for more. PM Sanae Takaichi urged immediate evacuation as strong aftershocks are expected all week."
