How far away can a 9.0 earthquake be felt?

25 Worst Earthquakes In History
- Valdivia, Chile. When it comes to the earthquake’s magnitude, the 1960 Valdivia earthquake takes the cake at 9.5, which was equivalent to a massive 178-Gigatons of power.
- Shaanxi, China. This earthquake has sometimes been called the deadliest earthquake in history.
- Sumatra, Indonesia.
- Aleppo, Syria.

What does earthquake feel like?

How strong is a 9.0 earthquake?
Essentially, each successive magnitude is 33 times larger than the last. That means a magnitude-8.0 earthquake is 33 times stronger than a 7.0, and a magnitude-9.0 earthquake is 1,089 (33 x 33) times more powerful than a 7.0 — the energy ramps up fast.
