It is not surprising that the earthquakes happened among clashing tectonic plate boundaries where numerous earthquake stations exist. Then, why do we need more? The significance of Sichuan and Tongshan
earthquakes of China is a wakeup call that major earthquakes of logarithmic Richter scales beyond 7 could happen
exactly within a single tectonic plate surprisingly. Thus, the previous border surveillance is broadened to areas
coverage. Judging the success of archival survey of NASA with the gravitational potential by Liu et al., we review a
unified earthquakes theory covering both the peripheral and the central plate in this paper, so that we can take
seriously the need of a comprehensive global surveillance of natural calamity in the Space. The earth surface crust, like a kitchen kettle lid, covers tightly the melted mantle rock layer, like a pea soup
cooking in the kettle. Given the time they will all become bubbling, rattling & shaking, known as the Bernard
instability. This instability is ubiquitous for any liquid state matter being heated from below, if and only if it has a
real positive thermal expansion coefficient. Likewise, the earth mantle is being cooked from below by an
enormously hot fireball of the size of a moon. The heat comes from the radioactive decay confined within the core
over eon's age. Due to the enormous gravitation attraction being always real positive and additive, the inner core is
bifurcated into 2 regimes, a heat-melted liquid metal regime, where the earth magnetic field is produced and
predicted by Faraday induction law. And further inside there exists a tightly squeezed solid metal ball regime, due to
the gigantic weight compression, as confirmed by sonar experiments. The complexity of earth Bernard instability is
due to the extra rotational Coriolis force that makes the up-down thermal convection side-way, creating the mass
imbalance and permitting in-situ measurements feasible at a distance.
