Outline of Final Research Achievements |
In order to improve the alertness of the earthquake warning system, we aim to use the earth's magnetic field signal that fluctuates with earthquake fault movement, and we are investigating some magnetometers for the purpose. In this study, simultaneous observations of TMR, FG, and SQ magnetometers were carried out to validate the magnetometers. The Pi signal was extracted by a combination of the RAW output of the TMR magnetometer and a bandwidth limiting filter. Maintaining continuous parallel observations is important for observing magnetic field changes associated with crustal deformation.
