So far we have not considered the attenuation of sound wave in to-and-fro
path by the atmospheric constituents. Incorporating the power loss due to
attenuation by air, the received backscattered power for isotropic homogeneous
turbulence becomes (McAllister et al., 1969)

Pr = received power (W)

Title: METHOD FOR THE DETECTION OF EARTHQUAKE PRECURSORS
Abstract: The present invention discloses a novel use of a SODAR
system to detect precursor of a major earthquake of intensity not less
than 5.0 on the Richter scale. The requirement for the SODAR to be able
to detect a possible major earthquake is that the epicenter should not be
beyond a distance of about 250 Kms from the position of the SODAR.

Thus, a new branch of S&T is emerging fast under

39. In the past 160
million years, India
has drifted the

meaning we have
faced maximum
Earthquakes.
Earthquakes of
unimaginable
magnitudes
40. Sumatra 9.1 magnitude earthquake in 2004 resulted in
shifting Various islands by 9 meters, think about India
shifting by almost 9000 km in the past 160 millions of
years.
Indian civilization must have seen the most devastating
earthquakes in the past and our worry is not over-our
worry is our enhanced population and no scope for
keeping any contingency grant in our social system
We spend lakhs and crores on marriages but if we ask,
even Rs. 10/- per head to be donated for research on
earthquake precursor, many would question even the
basic need?
43. Statistically, there is a
major earthquake in India
after every 6.8 years. A
deadly earthquake in
Himalayas is overdue.
44. When tectonic plates push against each other, a huge
amount of potential energy builds up at the plate
boundaries. In other words, potential energy is the
energy that is stored in the rocks because of tectonic
forces or stress.
An earthquake is the kinetic energy that is suddenly
released after enough pressure builds up along a fault.
Of course, some part of energy goes into breaking and
heating
Earth is heterogeneous so the velocity of propagation
is different in different materials- sharp slap divided
over n number of packets
45. 26 January 2011 (0846 IST) Bhuj earthquake
Loss
The quake killed around 20,000 people (including 18 in South
eastern Pakistan), injured another 167,000 and destroyed nearly 400,000
homes. The shock waves spread 700 km. 21 districts were affected and
600,000 people left homeless. Total property damage was estimated at
$5.5 billion and rising. In Kutch, the quake destroyed about 60% of food
and water supplies and around 258,000 houses .
So long we are living happily, we feel we will never
face a disaster-when we face, we are not there to even
to share our experiences. Also, even if we share our
experiences, there are very few who believe us.

49. KATHMANDU—The United Nations and numerous non-
governmental organizations seeking to assist quake-stricken
Nepal are blaming the country’s weak government, with a
reputation for inefficiency and corruption, for hindering the
massive relief effort.
Immediate Aid is necessary but it also makes a
country lethargic and drains out the initial outrage
to do something to save the society from the blunts
of earthquake-after all earthquakes do not strike
on daily basis.
51. We need to develop geo-radars to map the interior of Earth and keep a watch. Right now,
depth of penetration by EM waves(10-100 MHz) is the limiting factor.
Earthquakes usually begin deep in the ground. The point in Earth where the rocks
first break is called the focus, also known as the hypocenter, of the quake. The focus
of most earthquakes lies less than 45 miles (72 kilometers) beneath the surface,
though the deepest known focuses have been nearly 450 miles (700 kilometers)
below the surface. The point on the surface of Earth directly above the focus is
known as the epicenter of the quake. The strongest shaking is usually felt near the
epicenter.
52.
53. By the time a
seismometer
vibrates,
earthquake is
already at your
doorsteps and
there is no need
for any precursor
detection. But
these readings
are essential.
log E = 5.24 + 1.44M
M5 = 2.8 x 1012 joules.
M6 = 7.8 x 1013 joules
M7 = 2.1 x 1015 joules
M8 = 5.7 x 1016 joules
M9 = 1.6 x 1018 joules
M=log I/S S is 10-4 cm at a distance of
100 km. If I = S, then M = 0
But if I = 10 S, then M =1
Charles Richter, 1935)
54. P-waves travel through solid,
liquid, and gaseous materials.
When some P-waves move
from the ground to the lower
atmosphere, the sound wave
that is produced can
sometimes be heard by
humans and animals.
S-waves or secondary
waves are body waves, They
are slower than P-waves and
can only move through solid
materials.

Earth is a massive system and therefore, its movement will always be
fetal. But if there is any escape of energy (heat, EM/infrasonic), mass
(gases, water vapor, particulate matter), moment (mechanical energy),
with the sophisticated equipment, it can be detected. Of course, it
requires networking.

60. We can easily recognize physical objects and the damage is
permanent and easily detectable. Think of physical change

66. How magnetic field / electric field / infrasonic waves / heat
energy get generated and how do they move away from the
place of their generation / epicenter?

How fine particulate matter, charged particles, water
vapor and gases come out and how do they react with the
existing atmosphere? Do they lead to localized heating due
to release of latent heat energy?

69. General form of the gravity wave spectrum in the atmosphere. The
horizontal axis is the vertical wavelength of the gravity waves, while
the vertical axis is the relative energy density (adapted from
Gardner et al.). The numbers by the lines indicate the spectral slope
in each region. The numbers on the horizontal axis are the power of
ten for each tick mark (i.e. 3 means 103 = 1000). The gravity waves of
larger scale cascade their energy rapidly to smaller scales until
turbulent process continue passing the energy to smaller scales.

Infrasonic sensors

MEMS sensors for motions, acceleration, frequency
generators, power supplies etc.

2. How much is released as seismic wave, heat and other
forms?
3. Rocks have crystals and by changing pressure, how
electrical (EM) properties would change?
4. What is the effect of water table being pushed down on
earthquake effectiveness?

• Cobra is the most intelligent reptile which can see a man eye-to-eye
• They knew that low frequencies do not require Ears for sensing
• Cobra is sensitive to seismic vibrations : 50% body touch
• Before an earthquake strikes, charges on the earth’s surface increase. It
has been found that snakes respond to these charges and
become vertical in order to minimize the potential gradient between
the head and tail.
• Low maintenance cost and reliability: Can live for One year, without
food.
• Age ~ 28 years. Several times More than age of any modern equipment.
• Biological precursors are economical-High indigenous availability
• To stabilize, you need broad base and flexible columns
• To escape from rubbles, you got to be flexible, live in a circular hole.
• You can’t do this, earthquake has the capacity to kill like Cobra
• Wish we had understood much more through Sheshnag- the symbol

the Earth trembles and shakes.
