Heart Quake
23 June 2010 - Val-des-Bois, QC - An earthquake occurs when rocks break and slip along a fault in the earth. Energy is released during an earthquake in several forms, including as movement along the fault, as heat, and as seismic waves that radiate out from the "source" in all directions and cause the ground to shake, sometimes hundreds of kilometers away. http://earthquakescanada.nrcan.gc.ca/info-gen/faq-eng.php
