Place a ruler (or straight edge) on the chart between the points you marked for the distance to the epicenter and the amplitude. The point where your ruler crosses the middle line on the chart marks the magnitude (strength) of the earthquake. Depending on the size, nature, and location of an earthquake, seismologists may use several different methods and even different magnitude scales to estimate magnitude. The uncertainty in an estimate of the magnitude is about plus or minus 0.3 units, and seismologists often revise magnitude estimates as they obtain and analyze additional data.Oct 16, 2023 · What makes an earthquake "significant"?
