Outline of Final Research Achievements

In order to enable studies on infrasonic waves induced by earthquakes, tsunamis and avalanches, as well as to improve corrections to the precise observations of Earth’s gravity and deformations, direct observations of atmospheric pressure with dense microbarographs are becoming crucial in many fields of solid Earth science. The device optimized for such purposes has been developed in this study. The design of the new microbarograph includes a hysteresis-free formed bellow and non-contact optical fiber transducer to achieve required resolution within a reasonable manufacturing cost.
