Gravity distribution characteristics and their relationship with the distribution of earthquakes and tectonic units in the North–South seismic belt, China

Geodesy and Geodynamics, 2015
The North–South Seismic Belt (NSSB) is a Chinese tectonic boundary with a very complex structure, showing a sharp change in several geophysical field characteristics.

Analysing the enhancement edges of the Bouguer gravity anomaly map using sunshading method (area of the Tangier-Tetuan, Morocco)

Revista Facultad de Ingeniería Universidad de Antioquia, 2014
Sunshading is a powerful tool for the enhancement of edges in images. Given the azimuth and elevation of a source of illumination, it calculates the reflectance from a surface which is composed of the data to be interpreted.

Unrest at Domuyo Volcano, Argentina, detected by geophysical and geodetic data and morphometric analysis [PDF]

, 2019
New volcanic unrest has been detected in the Domuyo Volcanic Center (DVC), to the east of the Andes Southern Volcanic Zone in Argentina. To better understand this activity, we investigated new seismic monitoring data, gravimetric and magnetic campaign ...

Gravity pattern in southeast margin of Tibetan Plateau and its implications to tectonics and large earthquakes

Earth and Planetary Physics, 2019
There are many active faults in the southeast margin of Tibetan Plateau, where three large active faults zones, the Longmenshan, Xianshuihe and Anninghe, merge to form a "Y" shape. Strong crustal deformation and a complicated fault distribution accompany

New views of the spherical Bouguer gravity anomaly [PDF]

Geophysical Journal International, 2004
SUMMARY This paper presents a number of new concepts concerning the gravity anomaly. First, it identifies a distinct difference between a surface (2-D) gravity anomaly (the difference between actual gravity on one surface and normal gravity on another surface) and a solid (3-D) gravity anomaly defined in the fundamental gravimetric equation. Second, it

Field tests of a portable MEMS gravimeter [PDF]

, 2017
Gravimeters are used to measure density anomalies under the ground. They are applied in many different fields from volcanology to oil and gas exploration, but present commercial systems are costly and massive.
