SIMULATION OF EARTHQUAKES AND TSUNAMI THROUGH GSM NETWORK
[attachment=41503]
ABSTRACT:
Every year thousands of people die
because of earthquake occurs in a dangerous place or
during a defenseless sleep. Here’s a GSM-based seismic
alert system that could warn before an earthquake strikes.
Earthquakes strike without warning. The resulting damage
can be minimized and lives can be saved if people living in
the earthquake-prone area are already prepared to survive
the strike. This requires a warning before strong ground
motion from the earthquake arrival. Such a warning system
is possible because of energy wave released at the epicenter
of the earth quake travels slower than light. The warning
signal from the earthquake epicenter can be transmitted to
different places using satellite communication network,
fiber-optics network, pager service, Cell phone services or
a combination of these. The satellite-based network is ideal
when an alert system has to cover a large country like
India. For earthquake-prone states like Gujarat, a seismic
alert system using the global system for mobile
communication network spread throughout the state is
proposed here.
INTRODUCTION:
Earthquakes strike without warning. Every year
thousands of people die because of this. The result of
damage can be minimized by alerting the people
about the occurrence of natural calamities i.e., like
earthquakes, tsunamis etc. For this purpose, we use
advanced technologies like GSM (Global System for
Mobile communication technology). On 26
December 2004 an earthquake of 9.0 on the Richter
scale occurred west of Aceh in Sumatra,
Indonesia[1]. The epicenter was located at latitude
3.1degree north and longitude 95.5 degree east, about
680 kilometers northwest of KualaLumpur and 590
kilometers west of Penang. This earthquake has
generated a massive and disastrous Indian Oceanwide
tsunami that struck the coasts of a number of
countries in the region with high “tidal” waves.
PRE-EXISTING SYSTEM FOR TSUNAMI
WARNING:
Regional (or local) warning system centers use
seismic data about nearby earthquakes to determine if
there is a possible local threat of a tsunami [2]. Such
systems are capable of issuing warning to the general
public (via public address systems and sirens) in less
than 15 minutes. Although the epicenter and moment
magnitude of an underwater quake and the probable
tsunami arrival time can be quickly calculated. It is
almost always impossible to know whether
underwater ground shifts have occurred which will
result in tsunami waves. As a result, false alarms can
occur with these systems, but due to the highly
localized nature of these extremely quick warnings,
disruption is small.
NEED FOR TSUNAMI EARLY WARNING
SYSTEM
The tragedy happened because no country bordering
the Indian Ocean had any experience and capability
in the issuance of tsunami warning[3]. In the absence
of an effective tsunami warning system, the
Government will not be in a position to provide any
effective early warning to the public in the event of
another tsunami generated in the Indian Ocean.
Maintaining real-time continuous monitoring of
earthquake occurrences and tsunami on a 24-hour
basis throughout the year. Issuance of information,
advisory, notice, early warning and warning on the
occurrence of earthquake and tsunami that threaten
the security and safety.
LOCATION OF EXISTING SEISMIC
STATIONS:
The current real-time digital seismic network is able
to detect earthquakes and Accelerometers distributed
at nationwide remote stations. Each remote
seismological station is installed with a three
component weak motion seismometer and a 3
component strong motion accelerometer. The
network consists of one field station using digital
leased line for real-time data transmission and the
remaining 11 field stations with VSAT telemetry and
128kbps digital leased-line communication from the
service provider’s satellite gateway to the central
processing center for processing, analysis and
dissemination[6].
SEISMIC MONITORING SYSTEM:
The central processing centre runs BRTT’s Antelope
4.6 data acquisition and processing software on (2)
SUN Blade 150 workstations for real-time processing
and post processing. The Antelope Real-Time
System(ARTS) is also providing automatic event
detection, arrival picking, event location and
magnitude calculation. It provides graphical display
and reporting within near-real-time after a local or
regional event occurred.
CONCLUSION:
This earthquake alert systems senses earthquake
waves, transmits these discrete magnitude values to a
central place via.. GSM cell phone network, and uses
computer-based decision making to deliver alert
signals to the identified receivers placed at different
towns and cities for both public and government
consumption. The system is simple and could be
configured with available resources in the country.
Detailed simulation, feasibility study and
experimentation are required to optimize the system
and reduce the possibilities of false alarm.
