| 摘要 |
An earthquake prediction device comprises a predicted value calculation unit that calculates, from a prediction formula, a predicted value (MMIvp) indicating a predicted intensity of a ground motion on the Modified Mercalli Intensity scale, using a maximum velocity value (Vumax), which is the largest among absolute values of velocity component calculated by a vertical velocity calculation unit, after a sensor starts detecting the ground motion caused by an earthquake. The prediction formula is: MMIvp=±vlo g1 0(Vumax)+²v. |
