Huge Earthquake in Japan

I woke up this morning to news of the devastating earthquake in Japan. Seismologists report the quake was a magnitude 8.9! My jaw dropped when I heard this. Why? I experienced the 6.9 Loma Prieta earthquake in 1989. Everything shook for about 15-20 seconds and it caused significant damage. The earthquake that hit Japan today measures about 900 times stronger. Yes, 900 times stronger! It appeared to last about 30 seconds, and then the area was hit by tsunamis. Several aftershocks measuring greater than 6.0 were reported. Keep in mind that earthquakes measuring 6.0 and great are considered significant.

Several major earthquakes in the span of a few hours, and yet many buildings remain standing? This is a testament to advanced engineering. But science aside, I truly hope the Japanese people recover quickly from the devastating effects.
