Seismic boom: Breaking the quake barrier
Excerpt – (that I found very interesting – shearwaves earthquake waves)
With Rosakis on the verge of losing the bet, they put the slabs under slightly higher pressure by squeezing the fault tighter. Then, when they triggered a rupture, something odd happened: a fresh “daughter” crack suddenly appeared ahead of the main “mother” rupture, travelling much faster.
The daughter crack then expanded rapidly, and joined up with the mother rupture, causing the entire rupture to immediately start travelling faster than its shear waves, leapfrogging the “forbidden” speeds.
Not only that, it continued to produce new shear waves, which added to the first batch to produce a new, more powerful shock wave called a “Mach front”, which trailed behind the rupture in the shape of a boat’s wake (see diagram) (Science, vol 303, p 1859).
This is similar to what happens when jet fighters break the sound barrier and travel at Mach speeds; they create pressure waves as they speed through the air, but travel fast enough to catch up with them. The waves constructively interfere with each other to become one explosive sonic boom, extending in an expanding cone behind the aircraft.
