Earthquake 101 - Intensity vs Magnitude

Ever wondered what a “Magnitude 7.2” or "Intensity VI" earthquake really means?
Or why the same earthquake barely shakes one city but devastates another?

In this video, we break down the key difference between earthquake magnitude and earthquake intensity, how scientists measure seismic waves, and why two different scales are needed to understand the true power of earthquakes.

This deep-dive simplifies everything — from seismographs and Richter scale limitations to the modern Moment Magnitude Scale (MW), the Mercalli Intensity (MMI) Scale, and how much energy earthquakes actually release.

If you’re interested in Earth science, geology, natural disasters, tectonic plates, or simply want to understand earthquakes better — this video is for you!
