Abstract
The gravitational stresses caused by the density inhomogeneity of the Earth's crust in the Central Kuriles area are calculated.

Questions
Question (1)
Someone processes the Earth tides in the program VAV (by Venedikov)? I can not process the data obtained after 2005.
The program also does not work if to set the origin of time in 2008 and later (>D-ORIG: 2008 01 01 00). This is a problem of the program or am I doing something wrong?
