What scale are earthquakes measured on.

The most powerful earthquakes that have been measured are subduction earthquakes, up to greater than 9.0 in magnitude. All subduction zones in the world are at risk of subduction earthquakes with magnitudes up to or even greater than 9.0 in extreme cases, and are likely to produce tsunamis.The Moment magnitude scale (Mw), in contrast, "gives the most reliable estimate of earthquake size" for larger quakes, per USGS. According to the Michigan Technological University, "Moment is a ...You can measure an earthquake either by its size where the rock slipped, or by the amount of shaking that is experienced at a place that interests you.
