Web30 de jul. de 2024 · The advanced Richter scale today can easily measure earthquakes with negative size. A one-unit increase in the scale is equivalent to a 10 times increase in the size of an earthquake. This means that the numbers found on the Richter scale are comparable to the general logarithms of maximal wave magnitude.
