A magnitude 7.7 earthquake struck near Pitaloza Arriba, Panama.

Earthquakes of magnitude 4.5 or more

52earthquakes on the day

Strongest first. Magnitude is a log scale: each whole step is about 32 times more energy. Depth is how far below the surface the quake began; shallow ones shake the ground harder.

5 more happened out at sea, away from any country’s borders.

Counting smaller ones too, 94 earthquakes of magnitude 2.5 or more were logged worldwide. How many small quakes are recorded depends on how many seismometers are nearby, so this number is not compared with other years.
