Time spirals outward from the center: 7 days of Earth trembling, one full rotation per day. Each point is a quake. Size is magnitude. Position on the spiral is when it happened. Distance from center is which day.
Look for the clusters. The daily rhythm is real: tidal forces from the Moon and Sun create subtle patterns in when the Earth breaks. The deep quakes (500+ km down) trace subducting plates diving into the mantle. The shallow ones are where we live, and where we feel it.
