Story · U.S. Geological Survey
A week of earthquakes.
Roughly forty magnitude-4 events happen every day, and the number is remarkably stable. What is not stable is the energy: one large quake releases more than a thousand small ones, which is why the second chart needs a logarithmic axis. Control limits are open on the count, so days outside the usual range are marked.
