ABSTRACT
TO THE PROJECT "CAPACITY BUILDING IN THE PREVENTION AND
REDUCTION OF RISKS NATURAL DISASTERS AND EMERGENCY
SITUATIONS "
SECTION: IMPROVING OF THE EARLY WARNING SYSTEM FROM
EARTHQUAKES
PROJECT GOAL: REDUCTION OF DAMAGE AND HUMANS LOSS IN
DURING STRONG EARTHQUAKES.
OBJECTIVES OF THE PROJECT:
The task of earthquake early warning system is the rapid
determination of the start of earthquake, estimation of the
expected intensity of the protected city. This can be done to
find the energy that comes from the fast P-waves of
earthquake, which rarely caused of damage. Using of
information on P-waves, we first estimate the location and
magnitude of earthquakes. Less destructive P-waves arrives
first, and from it we can determine how much damage we
can expect from arrival of S-waves. In depending from
distance of early warning system can control of alarm for
20-200 seconds before arrival strong S-waves. The method
can provide a warning before arrival of S-waves, which
caused strong shaking and usually caused of big parts of
damage. Such as systems EEW are already out of work in
the world. Present time early warning systems existing in
Japan, Taiwan, Mexico, Turkey and Romania.
Effectiveness of the project:
- Early warning system about strong earthquakes is
destination for supply protects the most important sites
such as: pre-school and educational institutions,
hospitals and nursing homes, power supply systems,
transport and others.
- Early warning system focal of preparing earthquake
allow beforehand estimate of probability of the
manifestation zone and forces expected earthquake,
hereunder to take extraordinary actions on reduction its
negative consequences.
These measures allow greatly reduce the economic,
engineering and humanities negative consequences of
strong earthquakes.

For determine of location of active zone of the
forthcoming strong earthquakes M≥5.0, are using the original
method of magnetic location ULF that was out worked in the
Institute IEMPRW RAS (Institute of Earth Magnetism and
Propagation Radio Waves of Russia Academy Sciences). In
2000–2002yy. together with Japanese colleagues have been
obtained the first positive results of using Russian
equipment and their scientific methods. Previously,
equipment magnetic location in the range of ULF
(geophysical complex "Sourse-1") in during several years
was used in the sub-auroral zone in Russia for study
dynamics of ionospheric current systems, responsible for the
disturbance of the magnetic field of the Earth. At present, the
method claimed in a many of countries.
In 1980 years, by Uzbek seismologists were discovered
phenomenon of "Electromagnetic radiation at the final stage
of preparation of earthquake." By us had been out worked
hardware-software package that allows take the bearing on
angles of arrival of signals and on data Seismic Array and
define locate of source. This technology also will be involved
in during of realization of that project.
