Analysis of environmental temperature variation as a precursor of earthquake prediction using I2C

A number of naturally occurring events, such as earthquakes, hurricanes, tornados and floods are capable of causing deaths, injuries and property damages. Hazards associated with earthquakes are commonly referred to as seismic hazards [1]. Almost all earthquakes are preceded by physical processes commonly known as earthquake precursors [1]. Earthquake prediction is feasible by measurement and analysis of the amplitudes and spectra of ground motion. An instrumentation system is presented here for the detection of the variations of these precursors which changes well before the event. It consists of a sensor coupled to an embedded system to enable precise detection of variation in physical parameters. This helps us to interface it with the microcontroller through inter integrated circuits and send an alarm in the audio and visual form, when the parameters exceed beyond certain critical threshold. The measurements of the dynamic variations of the parameters indicate a departure from the routine values. The instrumentation system allows a comparative monitoring of such parameters with previously set standards along with an alarm system to trigger off during exceptional variations. This alarm enables us to put in place the preventive safety measures. The instrumentation includes the temperature sensor [5] (LM35) as the predominant sensor for detecting the relative parameters from the simulations of the earthquake.
