It seems like in the past few years, earth quakes are doing nothing but intensifying in not only quality of strength, but in quantity of strong earth quakes as well. Over the previous years you may have noticed quite a few more earth quakes not only in the U.S., but also through out the world.
This year on May 24th, seismologist’s recorded the biggest, deep earth quake recorded on earth. It hit in the Sea of Okhotsk, just off the coast of Russia, at a magnitude of 8.3. A study co-author and seismologist, Thorne Lay, from the University of California, was quoted saying, “it’s the biggest event we’ve ever seen.” The earth quake was 6.9 km below the earth’s surface. Seismologists do not understand how massive earth quakes can happen at such depths in the earth’s mantle.
On March 11th, 2011, a 9.0 earth quake violently shook everything around in Japan. The 9.0 quake, is the hardest on record to ever hit Japan. The earth quake produced a massive tsunami, which triggered the worlds worst nuclear crisis since the Chernobyl a quarter of a century ago. The devastating quake killed 20,352 people, and left many more with out jobs, school’s, and homes for months to come. Just passed the two year anniversary,on September 19th 2013, another strong earth quake hits in close to the area of the already damaged Fukushima Nuclear Plant. Luckily, this quake was less intense at only measuring a 5.8. The earth quake was also 12.4 miles below the earth. The quake being 12.4 miles under ground, made it so it was lightly felt by residents, and no one was killed. Again, seismologists do not know what causes such large quakes, so far under ground.
If you compare earth quakes from now, to the ones in the earlier 2000’s you can see that the quantity of earth quakes has gone down, but the intensity has gone up. In 2008 there were 41 earth quakes that caused many death’s but the quakes ranged from 4.8 to 7.9 on the rector scale. In 2009 there were 66 major earth quakes ranging from 3.0 to 8.1, 2010 had 12 major quakes ranging from 6.1 to 8.8, in 2011 there were 9 major quakes from 4.0 to 9.0, and 2012 had 5 major quakes ranging from 5.6 to 8.6. As you can see, in the past 5 years the intensity is rising in the earth quakes. Also, it seems as though we are in a ‘calm before the storm’. Every so many years, the earth quakes taper down in the number of major earth quakes. With the earth quakes intensifying, think of the number of lives that will be lost in the years to come.
