## How much stronger is a magnitude 9 earthquake than a magnitude 6?

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.

## How strong is a 9 earthquake?

Richter magnitudes

Magnitude | Description | Mercalli intensity |
---|---|---|

6.0–6.9 | Strong | VIII to X |

7.0–7.9 | Major | X or greater |

8.0–8.9 | Great | |

9.0 and greater |

**How many times will a magnitude 7 earthquake be stronger than a magnitude 5 earthquake?**

The magnitude 7 earthquake is 100 times as strong as the magnitude 5 earthquake. The 100 comes from the increase in the scale from 5 to 7, which is an increase of 2, so you multiply the strength of the weaker earthquake by 107-5 = 102 = 100, and that gives you the strength of the stronger earthquake.

**How much stronger is a magnitude 8 than a magnitude 4?**

1 higher magnitude is a 10 times stronger earthquake so a magnitude 8 is 10,000 times stronger than a magnitude 4.

### Which is stronger a magnitude 3 or 5 earthquake?

A magnitude 5 earthquake would be 100 times stronger than a magnitude 3 earthquake. The Richter scale, used to measure earthquake magnitudes, is a base 10 logarithmic scale. This means that a magnitude 5 quake would be 10 times stronger than a magnitude 4 (10^1 power), and would be 100 times stronger than a magnitude 3 (10^2 power).

### How many times as much energy does a 9.0 earthquake release?

A magnitude 9.0 earthquake doesn’t release nine times as much energy as a magnitude 1.0. Moment magnitude — the scale seismologists use to measure earthquakes — measures the exponential increase of energy as the magnitude increases.

**How big is a magnitude 9.0 earthquake?**

A magnitude 9.0 earthquake actually releases about 11,099,511,600,000 times as much energy as a magnitude 1.0. This graphic aims to show the dramatic increase from a magnitude 3.0 earthquake, the type of earthquake people barely feel, to a magnitude 9.0, the magnitude of the earthquake that hit Japan in 2011.

**Which is bigger an earthquake or a tsunami?**

The difference between these two magnitudes is… but it is times stronger (energy release).
