Description

Although it is little more than a large piece of rock with little geologic activity, the Moon also has its shaking one. These movements similar to earthquakes are divided into four categories, the first three (deep tremors, vibrations by meteorite impacts and thermal movements caused by heat from the sun) relatively harmless.

Already the fourth variant ( "shallow" tremors) can be quite unpleasant, reaching 5.5 on the Richter scale and lasting for incredibly long 10 minutes. According to NASA, another effect of them is to the Moon "sound like a bell." And the scary thing is that we have no idea of ​​the reason behind the earthquake, since the satellite does not have active plate tectonics.

Some researchers believe that the occurrences may be related to the activities of the tides on Earth, which are caused by the lunar attraction. However, this theory proves inconclusive, since the maritime forces affect the moon as a whole, but the tremors take place at specific locations.
