Earthquakes, seismology and how to read the map
April 20, 2026 Can Earthquakes Be Predicted? No scientific agency can predict the time, place and size of a specific future earthquake. Here is the difference between prediction, forecasting and early warning — and why prediction has failed. April 6, 2026 Foreshocks, Mainshocks and Aftershocks Big earthquakes come with a crowd. Here is what foreshocks, mainshocks and aftershocks are, the simple laws that describe them, and why a foreshock can only be identified after the fact. March 16, 2026 What a Magnitude 9 Actually Releases The magnitude scale is logarithmic, so the energy jumps are enormous. Here is how much energy each magnitude releases, why small quakes don’t relieve the pressure, and where the energy goes. March 2, 2026 The Ten Largest Earthquakes Ever Recorded From the magnitude 9.5 Chile earthquake of 1960 down: the ten biggest earthquakes since instrumental recording began, where they struck, and what they have in common. February 16, 2026 Richter vs. Moment Magnitude The “Richter scale” has not been the standard way to measure large earthquakes for decades. Here is the difference between Richter and moment magnitude, and why it matters. February 2, 2026 The Ring of Fire, Explained About 90% of the world’s earthquakes happen in a horseshoe-shaped belt around the Pacific Ocean.
