Abstract: An earthquake estimation method for more promptly estimating an earthquake on the basis of observation data. The earthquake estimation method includes, by a computer: generating an observation image showing a spatial distribution of seismic wave propagation on a basis of an observation result of seismic waves at a plurality of observation points on a ground; and estimating a parameter of an earthquake with respect to the observation image by using an earthquake estimation model in which a parameter of an earthquake including at least a position of a hypocenter and a magnitude is associated with a simulated observation image showing a spatial distribution of seismic wave propagation on a ground obtained from a result of a numerical simulation of the earthquake, performed with the parameter.

Abstract: A pollution level estimation system is a system that estimates a pollution level at a location to be estimated, the system including an image acquisition unit that acquires an image of the location to be estimated, a detection unit that detects a garbage portion showing garbage and a non-garbage portion not showing garbage at the location to be estimated in the acquired image, and a pollution level estimation unit that calculates areas of the detected garbage portion and non-garbage portion and estimates a pollution level at the location to be estimated on the basis of the calculated area.
