2. • AN EARTHQUAKE IS THE RESULT OF A SUDDEN RELEASE OF
ENERGY IN THE EARTH’S CRUST THAT CREATES SEISMIC WAVES.
• IT IS A NATURAL HAZARD THAT CAN CAUSE A LOT OF
DESTRUCTION TO HUMAN LIFE AND ECONOMY.
• IT IS A DEATH TRAP FOR AN OVER POPULATED COUNTRY LIKE
BANGLADESH.

3. • THE EARTH'S CRUST AND UPPER
MANTLE IS COMPOSED OF SEVERAL
LARGE, THIN, RELATIVELY RIGID
PLATES THAT MOVE RELATIVE TO ONE
ANOTHER.
• THERE ARE ABOUT 20 PLATES ALONG
THE SURFACE OF THE EARTH THAT
MOVE CONTINUOUSLY AND SLOWLY
PAST EACH OTHER. WHEN A PLATE
MOVES PAST ANOTHER OR PUSHES
ANOTHER PLATE, IT CREATES A
SEISMIC WAVE AND THE EARTHQUAKE
OCCURS.
