The ionospheric Total Electron Content (TEC) measurements were investigated at Universiti Teknologi Malaysia, UTMJ on 20 February - 20 March 2007. The observation was made 14 days before earthquake and 14 days after earthquake. TEC is extracted using GPS dual frequency data which in RINEX format that supplied by JUPEM (Jabatan Ukur dan Pemetaaan Malaysia). In order to reveal possible earthquake precursor through the changes variation of TEC reading, Southern Sumatra Indonesia earthquake that happened on 6th March 2007 is chosen as a study case. The results show that satellite facilities may detect earthquake precursors in ionosphere 5-11 days or a few hours before main shock and various grounds based or satellite observation have shown strong perturbation of the ionosphere after earthquake. The results show a good agreement with other researchers who studied other earthquakes.

    • "Zhihuan and Junjing (1990) have considered earthquake damage prediction as fuzzy-random event. Jusoh et al. (2008) have investigated the existence of the ionospheric Total Electron Content (TEC) using GPS dual frequency data. The variation of TEC can be considered as an anomaly a few days or hours before the earthquake. "

    ABSTRACT: Since early ages, people tried to predicate earthquakes using simple observations such as strange or atypical animal behavior. In this paper, we study data collected from past earthquakes to give better forecasting for coming earthquakes. We propose the application of artificial intelligent predication system based on artificial neural network which can be used to predicate the magnitude of future earthquakes in northern Red Sea area including the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez. We present performance evaluation for different configurations and neural network structures that show prediction accuracy compared to other methods. The proposed scheme is built based on feed forward neural network model with multi-hidden layers. The model consists of four phases: data acquisition, pre-processing, feature extraction and neural network training and testing. In this study the neural network model provides higher forecast accuracy than other proposed methods. Neural network model is at least 32% better than other methods. This is due to that neural network is capable to capture non-linear relationship than statistical methods and other proposed methods.

    ABSTRACT: Combined with a 51 SCM, AT89LV55, a three-axis accelerometer, ADXL335, and a digital-to-analog conversion chip, AD7708, a seismic alarm system has been designed, which can be placed and used in residents’ homes or some public places. ADXL335 is used to measure the acceleration of three axis, X axis, Y axis and Z axis. The design, a combination of performance chip AT89LV55 and other interface functions, functioned with the relationship between seismic magnitude and acceleration, so that we can resort to the software enquiry to figure out the seismic magnitude. In addition, large variation on Z axis would trigger the alarm that earthquake is coming. The procedure has been simulated and debugged on the actual Printed Circuit Board and a summary was made. In fact, the system delivers the seismic message promptly with high accuracy and provides some additional functions such as voice prompt and calendar.
