[題目 (title)]
Investigating the foreshocks of large earthquakes in Japan main land

[要旨 (Abstract)]
This is a progress of the previous research. The foreshocks of a mainshock are always regarded as random. However, according to the JMA earthquake catalogue of Japan main land from 2004 to 2019 (16 years), we investigate the possible foreshocks of earthquakes with magnitude larger than 3. We find that the mainshock will most likely occur in 2 days and 5 km after the foreshocks, also we calculate the possible probability of the occurrence. This might be helpful for earthquake forecast.
