| Research Abstract |
Microtremors refer to very small vibrations of the ground surface, hardly perceptible to human bodies, that are taking place even when there is no earthquake. Microtremor exploration is a generic term for methods that help to infer subsurface soil structures non-invasively by measuring microtremors on the ground surface. In the present study, we have expanded the SPAC method, a popular method of microtremor exploration, and have come up with a number of new sister methods for microtremor exploration. We have also created versatile software for microtremor analysis, with all new sister methods incorporated, and have tried to promulgate its use within the scientific community.
