at least 5.5
0.3 magnitude
An earthquake with a magnitude of 9 is 10,000 times larger in amplitude than an earthquake with a magnitude of 4 on the Richter scale. This means that the energy released by a magnitude 9 earthquake is significantly greater than that of a magnitude 4 quake.
Because the "magnitude scale is not linear, it is logarithmic (its numbers are an order of magnitude apart) this mean that the a magnitude 6 earthquake is TEN TIMES more powerful than a magnitude 5 earthquake and a HUNDRED TIMES more powerful than a magnitude 4 earthquake.

-3.0 magnitude or if you want the ground motion: Each time the magnitude increases by one unit, the measured ground motion becomes 10 times larger. For example, an earthquake with a magnitude of 5.0 on the Richter scale will produce 10 times as much ground motion as an earthquake with a magnitude of 4.0. Furthermore, an earthquake with a magnitude of 6.0 will produce 100 times as much ground motion (10 × 10) as an earthquake with a magnitude of 4.0.
The magnitude of an earthquake is measured on a logarithmic scale, so a magnitude 7.0 earthquake is 10 times stronger than a magnitude 6.0 earthquake in terms of the energy released. This means that the amplitude of ground shaking in a magnitude 7.0 earthquake would be significantly greater than in a magnitude 6.0 earthquake.
It is minor and you would hardly notice it and would not do much, if any, damage. See the link.
The impact of an earthquake can be measured in various ways, including its magnitude, duration, and the extent of damage it caused. The duration of an earthquake typically lasts from a few seconds to a couple of minutes, but the effects can be felt for much longer, especially in terms of aftershocks and recovery. The damage can vary significantly based on the earthquake's magnitude, depth, and proximity to populated areas. If you have a specific earthquake in mind, please provide more details for a more precise answer.
The magnitude of an earthquake is a number used to quantify how much energy was released during the earthquake. The earthquake in Japan that occurred on Friday, March 10, 2011, had a moment magnitude of 8.9.
A magnitude 8 earthquake is 1,000 times stronger than a magnitude 6 earthquake in terms of energy released. It can cause significantly more damage and have a larger impact on structures and the environment.
An earthquake with a magnitude of 3.0 is 10 times stronger than an earthquake with a magnitude of 2.0 on the Richter scale. This means that the release of energy during a magnitude 3.0 earthquake is 10 times greater than that of a magnitude 2.0 earthquake.
An earthquake with a magnitude of 5.0 has a shaking amplitude 10 times that of an earthquake with a 4.0 magnitude.
