Universal Coordinated Time UTC – ZULU is a 24 hour clock . There are extremes in preparedness, of course. As a basis of my work I use the 2015 Profile of Earthquake Risk in the District of North Vancouver by Earthquake Canada, wherein they state that there is 30% chance of a M7.3 in the middle of the Salish Sea in the next 50 years, that will bring down 839 buildings, just in the District of North Vancouver.

Later When you close that window you will be brought back here. This is my real challenge. If you are not mentally and physically in good shape, not frightened to do all of this on your own, not fully equipped and practiced in outdoor survival skills, then don't even try to do most any of this. If a really BIG earthquake hits expect to live by yourself, outside, for a long, long time.

Tsunami warning center scientists usually measure an earthquake's "size" with the moment magnitude scale rather than the older but more famous Richter magnitude scale. The moment magnitude scale is better suited for measuring the "sizes" of very large earthquakes and its values are proportional to an earthquake's total energy release, making this measurement more useful for tsunami forecasting. Moment magnitude numbers scale such that that energy release increases by a factor of about 32 for each whole magnitude number. For example, magnitude 6 releases about 32 times as much energy as magnitude 5, magnitude 7 about 32 times as much as magnitude 6, and so on. This animation graphically compares the relative "sizes" of some 20th and 21st century earthquakes by their moment magnitudes. Each circle's area represents its relative energy release, and its label lists its moment magnitude, its location, and the year it happened.
