Info on Quakes and Tsunami
Found some interesting sites that explains how eatrhquakes n tsunamis happen and how these two natural hazards are intertwined.

Do visit these sites if you're free. You'll know why it's not wise to go to beaches a few hours/days after a tsunami hits.. and why it's really, really not advisable to get your surfboards and hit the waves when tsunami occurs. ;)
