The Most Important Scientific Discovery of 2019: Seismic Universe
Study of earthquakes and moonquakes finds strong (M6+) quakes and tectonics are caused by externally excited resonance instead of mantle convection/inner heat.
The phenomenon of resonating vibration, or resonance, occurs when a physical system's natural period of oscillation matches another physical system's period of oscillation. As gravitational vectors in our Solar system's plane regularly stir masses of the rotating Earth, this disturbance under the right conditions magnifies the input tidal energy by 100s of times. Earth tectonic plates act as oscillating bodies of mass themselves, each with its natural vibration period.
Also, mantle convection models are designed such that they break down if one can demonstrate a coupling between continents and flows in the mantle – for example, a prominent Richter-McKenzie 1977 model in the same journal. Then this demonstration of a continent-mantle global coupling mechanism from successive M6.2+ (tectonic) earthquakes in the most extreme band of energies on Earth means that the same resonance and not convection drives the Earth's tectonic plates.
By analyzing the times of earthquakes occurrences in the USGS, GFZ, and EMSC records, Omerbashich extracted a complete set of periods of so-called superharmonic resonance. Omerbashich then analyzed the times of all Apollo Program's moonquake events – as a spatially (384,000 km apart) and temporally (half a century apart) independent verification. This moonquakes analysis resulted in the detection of the Moon's superharmonic resonance. Such independent confirmation of resonance tectonics and so its universality unveiled the external (astrophysical)
One of the greatest strengths (to the point of impossibility to question the result) of this discovery is that it is direct. Thus the analysis has captured continents and tectonic plates as they "ride" on mantle's resonance waves (rather than merely implying resonance from some intermediary data) while cyclically snapping into M6.2+ quakes at precisely those resonance periods.
