Effect determination system, effect determination method, and recording medium

An effect determination method comprising:

• acquiring a predicted displacement of a structure after an event, the predicted displacement being a displacement of the structure on a ground surface and having been predicted based on a pre-event displacement acquired before the event related to a ground of the structure;
• acquiring a post-event displacement of the structure based on an observation result of the ground surface observed after the event;
• and
• determining an effect of the event on the structure based on the predicted displacement and the post-event displacement.

A non-transitory computer-readable recording medium having recorded thereon a program causing a computer to execute:

• acquiring a predicted displacement of a structure after an event, the predicted displacement being a displacement of the structure on a ground surface and having been predicted based on a pre-event displacement acquired before the event related to a ground of the structure;
• acquiring a post-event displacement of the structure based on an observation result of the ground surface observed after the event;
• and
• determining an effect of the event on the structure based on the predicted displacement and the post-event displacement.
