The ground shakes beneath you. Your body sways a little. An alert pops up on your phone. You turn to a friend and ask: 書�eれた�� (Ima yureta?, Was that a quake just now?)

On Aug. 8, the �殤�リ (一庄壊鞄┃界鞄┃, Japan Meteorological Agency) issued its first-ever alert for a 掴今トラフ賞寄仇寳 (Nankai Torafu kyodai jishin, Nankai Trough megaquake) after a magnitude 7.1 temblor struck off the coast of Miyazaki Prefecture.

Again, that¨s not a 仇寳 (jishin, earthquake) ! that was a 賞寄仇寳 (kyodai jishin, megaquake) alert.
