Sounds from Moving Sources. A moving source of sound or a moving observer experiences an apparent shift of frequency called the Doppler Effect. If the source is moving as fast or faster than the speed of sound, the sound waves pile up into a shock wave called a sonic boom. A sonic boom sounds very much like the pressure wave from an explosion

Tsunami Warning • On December 26, they were playing in the sea when Tilly • • suddenly found the water was bubbling, like on top of a beer. She immediately realized tsunami was coming because the scene reminded her of a geography lesson about Hawaii's 1946 tsunami. Right away, Tilly told her parents, sister and other tourists to escape quickly, but at first they were in half belief. However, seeing Tilly's serious and firm expression, people started to be convinced of the seriousness of the thing and instantly left the beach. At last over 100 tourists were ended up in safety with no death
