In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according ...
The crests overtake the troughs until the leading edge of the wave forms a vertical face and spills over to form a turbulent shock (a breaker) that dissipates the wave's energy as sound and heat. Similar phenomena affect strong sound waves in gas or plasma, due to the dependence of the sound speed on temperature and pressure. Strong waves heat ...
It is a common understanding in psychoacoustics that the ear cannot respond to sounds at such high frequency via an air-conduction pathway, so one question that this research raised was: does the hypersonic effect occur via the "ordinary" route of sound travelling through the air passage in the ear, or in some other way?
After large earthquakes, there is an expectation that aftershocks could occur in the hours and days that follow, but aftershocks from some of the strongest earthquakes in recorded United States ...
Sound waves are pressure waves and it is at the speed of the sound wave the disturbances are communicated in the medium. When an object is moving in a flow field the object sends out disturbances which propagate at the speed of sound and adjusts the remaining flow field accordingly.
Aftershocks in the 3-4.8 magnitude range can be expected on average, according to the USGS, but some aftershock sequences are more energetic than others. What we know about NY, ...
Guiding their exploration was the idea that if mechanical waves in general are a known means of impacting objects, then sound waves in particular may have the power to move around the elements of ...
