[HDS09-P06] Software for analyzing Japan Meteorological Agency's earthquake database.

It is said that we should follow our ancestors' wisdom when we face or prepare for the natural disasters. This maxim also reminds us that we should make good use of the data from the past.
In this project, we are going to create a software which assists people in analyzing the earthquake data (Japan Meteorological Agency's Shindo-data, https://www.data.jma.go.jp/svd/eqev/data/bulletin/shindo.html).
We organized the records into station-by-station files, grouped the preceding and following monitoring stations at the same or very near locations, and corrected some inconsistencies. On the software, user selects the monitoring station, then, available data periods for that location will be displayed. Then the user set their own period of interest and then the relationship between the seismic intensities and the rates of occurrence are shown as a scatter chart.
At present, the functions of the software are limited to simple intensity-rate of occurrence relationship. But we are planning to add other functionality such as analyzing inter-quake intervals, correction of aftershocks and swarms, etc. The software will be available on GitHub at https://github.com/takuyakawanishi/eqanalysis, and people who can use Python will download it and run it on their own personal computers.
