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.

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.

Tohoku Earthquake and Tsunami, 2011

You watched it on TV, YouTube and here:
  1. 2011 Japan - Tohoku M9.0 Earthquake and Tsunami (above)  (YouTube Video – 26:48 minutes). This is a 26 minute long video of the 2011 Japan Earthquake and Tsunami. This was the worst tsunami to hit Japan in the past 1,100 years, and even today they are still recovering.
  2. 2004 Sumatra M9.1 earthquake (YouTube Video – 2:56 minutes) ruptured the greatest fault length of any recorded earthquake, spanning a distance of 1500 km (900 miles). - The portion of the fault that ruptured lies deep in the earth's crust, in places as much as 50 km (31 miles) below the ocean floor. There the two tectonic plates, which had been stuck together, suddenly broke free, the upper plate sliding back upward and to the west by as much as 20 m (65 feet) along the plate boundary.
  3. 1964 - The LIVE Look and Feel of a M9.2 to M9.3 Megaquake and Megatsunami - The Great Alaskan Earthquake 1964 - Magnitude 9.2 - Tsunami Affects The most powerful subduction zone earthquake in U.S. history, the 1964 magnitude (M) 9.2 Alaska earthquake, caused tsunamis, 129 deaths in three states and an estimated $2.38 billion in property losses (in 2017 dollars). Most deaths and damage along the Alaska coast resulted from local tsunamis caused by undersea landslides. The eruption of Mount St. Helen's, in 1980, killed 57 people, damaged more than 185 miles of roads, caused the cancellation of more than 1,000 airline flights and resulted in $1.1 to $2 billion in economic losses.
The USGS has developed a blueprint for advancing science and resilience from subduction zone hazards entitled Reducing Risk Where Tectonic Plates Collide – A Plan to Advance Subduction Zone Science .

“Release Date: JUNE 21, 2017
Subduction zone events pose significant threats to lives, property, economic vitality, cultural and natural resources and quality of life. The tremendous magnitudes of these events are unique to subduction zones, and they can have cascading consequences that reverberate around the globe.
The planet we live on is constantly shifting beneath our feet. Creeping along at speeds undetectable to you and me, Earth's massive tectonic plates are continually on the move, and nowhere is our home planet more geologically active than where these plates converge. For example, (British Columbia, Canada) and the United States of Alaska, Washington, Oregon, northern California, the commonwealths of Puerto Rico and the Northern Mariana Islands and the territories of American Samoa and Guam are all situated where two tectonic plates collide, putting them at risk from the world’s largest earthquakes, powerful tsunamis, explosive volcanoes and massive landslides on land and offshore. Scientifically speaking, these areas are called “subduction zones.”
From USGS – United States Geological Service:
Do you want to get really frightened: Cascadia's Fault: The Coming Earthquake and Tsunami that Could Devastate North America – via Amazon (as at May 20, 2018) ~ Be sure to get the most recent edition - Includes a new Afterword by the author on the 2011 Japan Earthquake, the lessons learned, and the parallel threat to North America. A new study just published by the US Geological Survey confirms and underlines many of the issued raised in the first edition of Cascadia's Fault.

    In early September, 2017, I look in on the Japanese Seismic Team watching over Cascadia's Fault. There were three (3) full time staff, on dayshift, with others around to give them 24/7 full time monitoring. At least the Japanese take this seriously. The last M8.7–9.2 was at 9PM local PST on January 26, 1700.
