SEISMIC STAR
FOR EARTHQUAKE PROTECTION
RF Patent#2006553, January30,1994
"SEISMIC STAR" IS AN UNDERGROUND WALL DESIGNED FOR DISSIPATION OF SHEAR RUPTURE BETWEEN SOIL AND "SEISMIC STAR" WITH REDUCTION OF IMPULSE SURPLUS PRESSURE UP TO 40% & MORE.
This not a well-known self sacrificial underground screen.
A seismic wave destroys the soil around the "Seismic Star".
Your property stays on and unharmed.
World map of the most active earthquake areas,
About 200,000 earthquakes occur every year.
Most of the earthquakes began from the bottom of the ocean and young tectonics.

Tremendous tectonic force spreads to the continental shelf with reflections causing vertical and horizontal impulses of surplus pressure of geological plateaus.

The vertical and horizontal impulses are statistically evaluated to be 15% and 85% of the whole tectonic force, respectively.

On the pictures above and left are shown the traces of volcanic activity, with water, land and ice as the epicenters of the earthquakes.    
On the pictures above are shown typical "trenches" as a result of rupture of soil after an earthquake shock wave.
Buildings and structures are deformed and ruined as a result of  a horizontal shock wave. The direction of a shock wave and the type of destruction are shown on the pictures below as an example of it. 
Obviously, the reduction of the horizontal shock wave would prevent those structures from destruction. "Seismic Star" is capable of reducing the level of impulse surplus pressure on structures by 40%, which would result in insignificant damage or none of it. 
The results of research are shown on the page "SEISMIC STAR BROCHURE" where it is proven that shape of the underground Seismic Star" depends on the type of soil, protected structure, required level of protection, etc. which will be analyzed by our special software for every specified project.
