SEISMIC STAR
World map of the most active earthquake areas, 
About 200,000 earthquakes occur every year.
On the picture above is shown typical "trenche" as a result of rupture of soil after an earthquake shock after 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.  

Dear Colleagues,

DIFFRENCES BETWEEN SEISMIC STAR AND SACRIFICIAL SCREENS
Self- sacrificial screens trenched into the soil provide direct reflection of seismic wave with unpredictable shock absorbing effect.

In the most of cases those screens got to be:
     - broken, when placed into the natural clay, rocky shelves, stumped sand, etc.  that’s why those screens recognized as self-sacrificial ones, 
     - or moved together with displaced soil represented by weak geological deposits, which are a majority in urban and agricultural areas. 

Here is only way to enhance shock absorbing effect to provide thickness of the screens at 0.5 m and depth of placement by 6 to 9 meters. The screens have to be made of rocky masonry walls or by massive concrete injection. Well known examples are fenced monasteries and castles stays for hundreds of years after earthquakes among disappearing and restored cities. Those “fences” are made of the rocks or bricks with thickness enough to resist to the artillery and depth to prevent tunneling under by the enemies.     
Seismic Star is an invention registered after four years of experts evaluations and three times successful applications. Thousands of men hours are compressed into our software to compute angles between screens shaped into the star trenched around protected structure or along of it for linear ones. The initial data is required to be listed by:
    - Shape or plan of the building or structure with the contour's dimensions.
    - Geological type of the soil into the depth of at 1 m to 3 m.
    - Required level of shock absorption (> 50%; between 25% and 50% and at 25%).
    - Expected earthquake magnitude known for certain area or country.  

Following to the steps of instruction on computer’s screen results in the radius of Seismic Star, length of each side of the Star’s “beam” and topography of damaged soil from both sides of the Star’s screens. The depth of placement is 1 m and thickness of the screens could be any. 

Printed images are shown on website www.seismicstar.com “Seismic Star Brochure > pages 6,7.” On the pages 8 and 9 are shown results of the standard experiments without screen, with a screen as a circle and with a screen as a Seismic Star. The width of the screen depends on a trench machine excavation applies.

    - Expected earthquake magnitude known for certain area or country.
Technically speaking, computing gives exact angle between Star’s beams equal to the angle of the soil’ natural bulk distribution (this is an angle of the soil lump strewed from the top). Only in this case the particle of the soil strikes the surface of the screen and kicks back under the same angle, which results in lowest possible impact energy. 

When angle of the force strike’ direction is deviate by 1 grad from the angle of trenched screen, then sin 1 grad is 0.01745. For instance, the earthquake force strikes by 10, 000 m tons x 0.01745 become 175 m. tons. On a practice there is no impact on building foundation at all, but soil from both sides of screens is crumbled and ready to attenuate next impact. Our software guarantees at 0 grad of deviation with protection from mistake on a job side by up to 11 grad.

Introduction
From its starting point in 1992 to the present day, the Council has created respected thought leadership on business and sustainability.

The Council plays the leading advocacy role for business. Leveraging strong relationships with stakeholders, it helps drive debate and policy change in favor of sustainable development solutions.

The Council provides a forum for its 200 member companies - who represent all business sectors, all continents and combined revenue of over $US 7 trillion - to share best practices on sustainable development issues and to develop innovative tools that change the status quo. The Council also benefits from a network of 60 national and regional business councils and partner organizations, a majority of which are based in developing countries.

By thinking ahead, advocating for progress and delivering results, the WBCSD both increases the impact of our members’ individual actions and catalyzes collective action that can change the future of our society for the better.
