Strange sound are being heard around the world and there are no apparent explanations. In San Diego, another large earth quake shaking boom caused thousands of residents to panic and worry about a bomb having exploded. However no bombs exploded and the true source of the loud sound is still unknown. 

Many UFO researchers like myself do believe that UFOs entering and exiting wormholes in Earths atmosphere causes such sounds. Also when an underground alien base is being expanded, such sounds are created. Remember the alien base in the shape of an oval disk found off the coast of Malibu, California?
