3PRINCIPLE METHODS IN EPR
- 1) Astronomical
- Stellar constellation (planets stars)
- Moon, a Celestial body Earth in
straight line - Turning points of the moons relative
motion to the earth - Tidal Generation Forces Resonance TGFR
- Data can be computed in advance
much in advance
4- 2) Geomagnetic field change
- Change in Geomagnetic field occurs 6-8 m before
EQ. - - Continuous monitoring Geomagnetic field
is required - Audio, video spectral disturbances just 10 to
20 hrs - before earthquake occurrence.
- - Lattur Andamans EQs phone complaints
increased. - - In Turkey, Japan China mobile phones
- malfunctioned 50 to 100 minutes before
EQ - - Telephone exchange data useful in
land, mobile.
6-8 m
5- 3) Triangular network GPS stations
- Area change ratio from Simultaneous
continuous - Geodetic measurement is converted to annual
change - ratio ppm.
- Early warning should be issued if the change
in XY, XZ - or YZ plane is gt 3ppm
- I stage warning 4 - 9 ppm
- II stage warning 10 ppm
- III stage warning gt10 ppm
- ve sign indicates tension - ve sign indicates
compression
3-6 m
6- 4) Differential SAR interferrometry
- Differential Interferrometry
- - Provides relative measurement, few cm or
even less - movements in vertical direction.
- Small elevation changes caused by the buckling
of the - earths surface prior to EQ can be measured.
- For monitoring pre, co post seismic Earths
Crust - Dynamic Grid 4 satellites or more needed.
- NASA 7 d repeat L- band InSAR 4 satellites
with 10 m - resolution, okay.
- Long-term measurement of interseismic strain
- accumulation to lt1 mm/yr resolution
-
1-2 m
7- 5) Thermal InfraRed
- A huge isolated temperature increasing area
appears far - from Epicenter before EQ 2-6 deg C wrt
peripherals. - The thermal spectral resolution of 0.12-0.5 deg
C is high - enough for EQ precursor detection.
- Increase of Brightness values Temperature
Temperature - Increasing Area IBvTTIA direct function
of magnitude. - IBvT TIA
- 1-3 L sq. km Ms. 5.
- 4-7 L sq. km Ms gt 6.
- gt 7 L sq. km Ms. 7.
1d to2 m
8- 6) Animal abnormal Jump frequency budgerigars
- Budgerigars is a kind Parrot which is used
for EQ - precursor detection.
- 600-700 Vs gt2000 jumps p/d
- No Information on direction,epicenter,Mag,t
7-13 d
9- 7) Gravity method
- In deformation zone, on earths surface
subjected to - displacement or movement of the earths
gravity center. - Given, at least 3 measuring points of earths
gravity force, - triangulation procedure allows locating the
epicenter
5 6 d
10- 8) Crustal stress measurement
- Before EQ crustal strain pulse signals.
- Relative change of crustal stress reflects
seismicity, - Hence crustal stress value is adopted instead
of - absolute value.
- Measured by a crustal stress transducer, the
strain in 3 - directions on a level underground.
- Principal strain (crustal stress crustal
strain elastic - modulus )
- Its direction is towards epicenter.
1 3 d
11- 9) Infrasound Waves ISW
- Abnormal Infrasonic wave signals has Ultra low
frequency - (lt1 Hz), longitudinal vibrations in the air,
propagate very - long distances, without significant attenuation
and distortion. - ISWs released from fault fractures rock
destruction prior - to large EQs at epicenter.
- Infrasonic sound measured in a star topology
with - optimum array configuration using
- low frequency microphone or by
- high frequency barometer sensors.
- A high, 1.250 mV 10Pa sonic P
- EQ Ms gt7-7.5
- EQs Precursors 0.004-0.1 Hz.
1-9 d
12- 10) Geoelectric pulses
- Normal pulse is smoothly round curve, but
before EQ - abnormal.
- Amplitude of the abnormal signal determines
- the magnitude.
- Procedures are same as of ISW

- Accomplishing envisaged endeavor
- Integrated Cardinal Strategy.
- Comprehensive Data Integration, then
Synthesize. - Multi disciplinary, component, Poly
Dimensional - data encompassing multiple of
multiplicative complexities, - Use of multiplicative additive divisive
subtractive - methodologies etc.
- Comprehensive Integration to differentiate the
multi data set - precursors reliable response more
information than can be - derived from single data set, techniques more
supportive, - more confident
- Integration of multiple data sets and composite
digital image - generation.
15- Computerized image processing involving data
2 - and feature extraction techniques
geometrical, structural, - spectral, statistical with 2 or more, Image
data fusion, based - on pixel, feature, decision pixel,
algorithm should be in line - with scientific doctrine, a continuous
processes to refine and - improve the visual image exploitation by
human image - interpreters.
- Decisions levels on fusion techniques are
knowledge logical, - syntactical, contextual and identity
statistical inferences based - global seismic policy, Public education,
seismic proof ts safe - planning and constructions, public early
warning reach out - communications, real time emergency services
disaster relief and - management.
- Global Team Effort.
- Integrated Global Strategy.

22DISASTER MANAGEMENT STRATEGY
23- Initially, precursors identification routine
Long and Medium - range predictive techniques, irrespective of
areas are seismic or - aseismic, followed by Short range on alert
in seismic or aseismic - narrowing down the imminent event.
- None may follow logical sequence.
- Likelihood that medium and short range could
be in sequence, - long range may or may not be an indicator.
- On alert Short-Range Tools must be in place
and vigilant in the - long and/or medium ranges in seismic or
aseismic-alerted in the - regions for continuous surveillance and
monitoring.
24- Our need of the
hour is - an automated on line surveillance system
- To predict Imminent Earthquakes Precursors
Detection - At least 3 days before, should possibly be
accomplished. - Constituting an Earthquake Research Authority
- ERA act as a nodal agency to coordinate with
recently - forming National Disaster Management Authority
NDMA. -
- Researchers as and when they notice imminence of
an event, - should report to the ERA only, who intern can
deal with the - situation as deemed fit confidentially,
including conveying - to the public at an appropriate time, so that
panic situation - is avoided.
25- The NDMA should ensure that State District
Level - S,DDMAs be in place.
- Researchers as and when they identify long
range indicators in an - area, it should be confidentially be informed
to the ERA, to be - passed on to N,SDMAs.
-
- When the medium range precursors are identified
in the same - area, then alert should be passed on to all
the three DMAs - through ERA to NDMA.
- Finally, when the event is identified in the
short range in the same - area, then ERA to coordinate with all the
three DMAs to get not - only be alerted, but also should be in a
position to convey to the - area people concern about the imminent
event, from time to time, - with the latest updates and to get prepared
to face the situation - Without any panic, a proper communication
channel is to be - devised. Strict highest level of
confidentiality should be maintained
26Medical Precurssors
- Abnormal cell growth precursor
- Positron Emission Tomography
- computerized tomography PET-CT
- Color shades chemical levels of cell
activity. - Exact location of abnormal cell activity
- invisible on CT.
- A complimentary, not competing image
modalities
27My Medical Forecast
- Signal Processing Doctrine principles are same
in any scientific - pursuit, including interpretation
- Cardiac ECG or
- EQs seismogram
- In fact signal processing technique is adopted
in - medical applications
- Automatic processing of the foetal MCG, Cardiac
- diseases estimate
- A precursor sensor like a wristwatch on human
body to - monitor on selected intervals Vital organs
functioning and - connected to a centralized computerized
Database, gives - warning signals replacing the existing
periodical preventive - medical checkups, including scans, blood
tests etc.
28- SUGGESTIONS
- EPR should be taken up by Academic,
Professional and - Research Institutes with collaborative
projects with - centres where such know-how exists.
- Global coordinated team effort deeper insight
with tenacity. - A false alarm can cause panic, hence special
- care is needed.
- Cardinal aim is narrowing down the event
predictive - process by employing the Prediction Precursor
- Techniques of a three-tire system
- 1) Macro 2) Meso 3) Micro levels
- With the help of Space and Ground-borne systems
29- SUGGESTIONS
- Symptomatic approach Vs Scientific doctrine
- Supernatural science needs to be pursued,
parallelly - United Nations Universitys Associated
Institutions - Research Centers of Global Scientific
Excellence in various - countries
- Student participation in Masters and Doctoral
programs - UN, World Human Rights Commission and NGOs
