The most recent view, based on consensus drawn from several reports, is that two ancestral waves of surface-dwelling stock invaded the region of the caves.
When I saw the initial wave of Surface reviews hit, I started pinging some folks to see if I could get my hands on one to review as well.
Resonance occurs when the wave vector of surface plasmon wave equals to the tangential component of evanescent wave vector (i.e., the phase-matching condition) under appropriate incident conditions (e.g., incident angle and wavelength).
Within the past few million years, at least five independent invasions by two different migration waves of eyed surface fish have established independent cavefish populations [ 15- 18].
Within the past few million years, at least five independent colonizations by two different migrational waves of eyed surface fish have established 29 geographically isolated Astyanax cavefish populations in northeastern Mexico [ 17- 20].
The initial signatures in Figure 2 with a propagation velocity of 3,457 m/s are most likely caused by a Rayleigh wave (a type of surface wave during earthquakes), followed by acoustic waves triggered by the Rayleigh wave.
Singh (2017a, b, c) presented the kinematic wave theory of surface runoff.
The time delays, as well as longer durations of the waves, indicate that generation of surface waves in the accretionary prism also increases the amplitudes of waves from subsources in the area of anomaly 3.
This population analysis agrees with prior reports suggesting cave populations originated from two ('old' and 'new') waves of ancestral surface-dwelling forms [ 7, 9- 11, 21, 23]).
As the hypocenter distances exceed 70 km, source-radiated body waves enter the Kanto Basin, and excitation of surface waves (Love waves) occurs at the edge of the basin.
