Problem : Earthquake
Earthquake is one most dangerous natural disaster in this decade.
The movement in the interior of earth crust might generate earthquake
from seismic wave with different magnitude. The intensity and frequency
of strong earthquakes seem to be increased year by year all over the
world and damage buildings, properties and lives each year. The modern
technologies seem not to be intelligent enough to warn us before it
happens. In Thailand also confronted of earthquakes with high magnitude
damaged wide spread several provinces in Chiengrai, North of Thailand.
