On May 22, 1960, a 9.5 magnitude earthquake occurred near Valdivia, Chile. It remains the largest magnitude earthquake ever recorded.

Tsunamis resulting from the quake caused destruction and loss of life in Southern California, Hawaii and as far away as Japan and Alaska.

Four years later came the Great Alaska Earthquake of 1964. With a 9.2 magnitude, it's the second-largest earthquake ever recorded.

Earthquakes are scary. We had a "big" one here, 5.2 in 2013.

Hummm...I don't remember anyone talking about it. I guess our media coverage has just made our world smaller.

A little more trivia

Richter scale
The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquakes. On the Richter Scale, magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 might be computed for a moderate earthquake, and a strong earthquake might be rated as magnitude 6.3. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; as an estimate of energy, each whole number step in the magnitude scale corresponds to the release of about 31 times more energy than the amount associated with the preceding whole number value.

Experiencing an earthquake is very unsettling. When I lived in Vancouver, WA, back in the '60's, we had 2 episodes of tremors. It's a totally out of control feeling to feel the earth moving underneath you.

Was present during the 89' quake in San Francisco.
Affected everyone I knew in some way or another.
Hours earlier we drove over the freeway section that collapsed
like a pancake.
