Since the Sixties, the turning point marked by the Plate Tectonics global theory has provided new ideas for the interpretation
of the complex geodynamic evolution of the Mediterranean area. The renew...
Tidal gravity observations at Mt. Etna and Stromboli: results concerning the modeled and observed tidal factors
Tidal gravity models Tidal loading
2015/9/1
Continuous gravity observations performed in the last few years, both at Mt. Etna and Stromboli, have prompted
the need to improve the tidal analysis in order to acquire the best corrected data for t...

The variations of gravity field have been analyzed in this article, in order to find disturbances in the vicinity of recent great earthquakes epicenters including Chile (February 27, 2010), Tohoku-Oki...
Modeling of the 3-D subsurface structure around damaged area due to the 1909 Anegawa earthquake using gravity survey
gravity survey 3-D subsurface structure estimation of strong ground motions 1909 Anegawa earthquake
2009/3/5
It is important to understand the detailed 3-D subsurface structure to estimate the strong ground motions. For this purpose, we will confirm the usability of the gravity survey and propose a process f...
Large Trench-Parallel Gravity Variations Predict Seismogenic Behavior in Subduction Zones
Large Trench-Parallel Gravity Variations Predict Seismogenic Behavior in Subduction Zones
2014/4/9
We demonstrate that great earthquakes occur predominantly in regions with a strongly negative trench-parallel gravity anomaly (TPGA), whereas regions with strongly positive TPGA are relatively aseismi...
