Earthquake & Tsunami Cosmic Clock Simulator

Click an earthquake to see where and when it struck, whether it launched a local or ocean-basin tsunami, and how nearby cities and populations were affected.

Note: Earthquakes themselves do not change global climate the way large volcanic eruptions or asteroid impacts do. Here “global” mainly means ocean-basin tsunamis and world-scale social/economic effects.

🧭 Cosmic Clock & Effects

Select an event on the left to see:

  • Latitude, longitude, hemisphere, and latitude band (cosmic clock position)
  • Approximate season of the main shock (when month is known)
  • Whether there was a tsunami (local vs ocean-basin)
  • Nearby cities / populations and aftermath (famine, migration, rebuilding, etc.)
