Abstract
After the 921 Earthquake, people in
Taiwan realized earthquake is one of the
large-scale natural disasters with huge damages.
To accurately forecast earthquake, especially
the short-term one is the important basis for
disaster mitigation. There are many
earthquake-forecasting techniques developed
by the experts from USA, Japan, China and
Russia were successfully in many cases
through using earth-physics, earth-chemise,
and crest-movement detection methods.
Among these methods, applying thermal
inferred-Red imagery in the prediction is the
most feasible and cheapest approach.
In this research, data bases of earth-quake,
thermal imagery, pre-sight data were
established, and the abnormal-thermal and its
movement were detected and applied to predict
the earthquake center location, time and their
scale based on the red-swollen theory. The
thermal imagery were tracing form 1.5 month
before the earthquakes, the abnormal warm
areas and their movement was tracked and
applied in digging out the relationship among
the movement and the centers of earthquakes.
A computer-assistant prototype system
was developed based on the detecting
techniques and forecast model developed in
this research. The tracking paths of abnormal
warm areas were found, the temperature
changes around the centers of earthquakes
indicated that there might be a concave area in
term of temperature around the center of
earthquakes. Finally a proposal of an
integrated, long-term research project for better
earthquake forecasting and monitoring was
presented.
