The amount of energy released increases about 40 times every time there is an increase of one unit on the magnitude scale. No, except for very rare exceptions. Shake, rattle, and roll! However, building codes do not prevent certain types of non-structural damage. Back to Science for Kids Earthquakes are caused by the slow deformation of the outer, brittle portions of "tectonic plates", the earth's outermost layer of crust and upper mantle. Warnings also alert emergency management officials to take action for the entire tsunami hazard zone.

The first seismic hazard maps for use in Canada have been in use since 1953. The effects (or intensities) experienced at different places were different, but the magnitude of the earthquake is unique; in this example, it was 6 on the Richter scale. This has nothing to do with reality but is Hollywood's version of earthquakes.

In most cases, these shocks (called aftershocks) will be smaller; therefore, the vibrations will be weaker. Where can I find information on seismic hazards in Canada? Test your understanding of Earthquakes concepts with Study.com's quick multiple choice quizzes. This earthquake’s tremors were felt in California, Hawaii, and Japan. In Canada, the only loss of life related to an earthquake, although indirectly, were those caused by the tsunami created by the 1929 Grand Banks earthquake.
