Rapid assessment of damage potential and size of an earthquake at the station is highly demanded for onsite earthquake early warning. We study the application of τc∗Pd for its estimation on the earthquake size using 123 events recorded by the borehole stations of KiK-net in Japan. The new type of earthquake size determined by τc∗Pd is more related to the damage potential. We find that τc∗Pd provides another parameter to measure the size of earthquake and the threshold to warn strong ground motion.
