Many users could see the alerts as false alarms if the quake never developed into a more powerful tremor. When sound waves accumulate in front of a jet moving faster than the speed of sound, they eventually merge into a single wave that a person on the ground hears as an explosion, or sonic boom. The amount of energy released in an earthquake is controlled by how much of the crust breaks. Over the years, scientists have also found that the duration of slow quakes can vastly differ.
