Is the Earth Praising the Lord?
Every bell made has its own tone, depending on its size, shape and composition. It turns out that the Earth, too, rings like a bell. This ringing, called free oscillation, is caused by earthquakes. A powerful earthquake in Chile in 1960 with a magnitude of 9.5 left the entire Earth ringing for days afterward. As the Earth rang, its entire surface rose and fell by a centimeter every 54 minutes. But it happened so slowly it could be detected only by sensitive instruments.
It was while studying these earthquake-caused oscillations that Japanese researchers discovered that the Earth also constantly vibrates. These vibrations appear to have nothing to do with earthquakes. The vibrations were discovered using an extremely sensitive instrument that measures gravity. These constant vibrations, with periods ranging from two to eight minutes, raise and lower the surface of the Earth the diameter of a single molecule. In 1998, scientists at the University of California, Berkeley, tried to confirm the vibrations.
What's causing this constant vibration? There is so much energy in these vibrations that they cannot be accounted for by small earthquakes. Scientists are theorizing that it could be caused by the Earth's winds. They say that there is enough energy in the Earth's winds to cause the vibrations. Others speculate that there could be some unknown processes going on within the Earth that may be causing the vibration.
Or, we might suggest, scientists have discovered that the Earth does literally praise its Maker through these low-frequency vibrations.
