Reformulation of the Vening-Meinesz Moritz Inverse Problem of Isostasy for Isostatic Gravity Disturbances
Crust Gravity Isostasy Moho Interface Spherical Harmonics
2013/3/11
The isostatic gravity anomalies have been traditionally used to solve the inverse problems of isostasy. Since gravity measurements are nowadays carried out together with GPS positioning, the utilizati...

Cyclonic Events Arabian Sea Bay of Bengal SST Chlorophyll-a Ecological Structure
2013/3/8
In recent years we are observing devastating cyclones like Nargis, Gonu, Sidr, Liala, Phet etc in the North Indian Ocean associated with heavy rains, thunderstorm, high tide and intense winds that cau...
Disturbances in groundwater chemical parameters related to seismic and volcanic activity in Kamchatka(Russia)
Disturbances groundwater chemical parameters seismic and volcanic activity
2009/12/14
Starting from 1992 geochemical data are being collected with a mean sampling frequency of three days in the form of the pH value and of the most common ions and gases in the groundwater in one deep we...
Variations of phase velocity and gradient values of ULF geomagnetic disturbances connected with the Izu strong earthquakes
phase velocity gradient values ULF geomagnetic disturbances Izu strong earthquakes
2009/12/11
Results of study of anomaly behavior of amplitudes, phase velocities and gradients of ULF electromagnetic disturbances (F = 0.002 – 0.5 Hz) before and during a seismic active period are presented. Inv...
Nonlinear mechanism of tsunami wave generation by atmospheric disturbances
Nonlinear mechanism tsunami wave generation atmospheric disturbances
2009/12/9
The problem of tsunami wave generation by variable meteo-conditions is discussed. The simplified linear and nonlinear shallow water models are derived, and their analytical solutions for a basin of co...
Layer disturbances and the radio-echo free zone in ice sheets
Layer disturbances radio-echo free zone ice sheets
2010/2/3
Radio-echo sounding of the Antarctic and Greenlandic ice sheets often reveals a layer in the lowest hundreds of meters above bedrock more or less free of radio echoes, known as the echo-free zone (EFZ...
