A Tsunami is expected to outpour itself, I mean the chaos it contains, but definitely NOT drizzle, right? But that's only on the outside. Before the chaos is vented out, apparently the disturbances drizzle on the inside and gradually build up into that chaos. For how long does a Tsunami actually drizzle on the inside then? The circuitry of the Earth, if one observes closely, is very pro-life. The preference (infact always, but to play safe, I'd say, most of the times) is to save as much life as possible. If you follow the Earthquakes happening worldwide, you would see that 98% of the disturbances vented out of Earth happen to be in uninhabited areas or if they do happen in inhabited areas, they are of a very low magnitude that do not hamper or even bother life in any way. Only an intelligent organism can manage its chaos so systematically. Oh, when I say intelligent, I implicitly mean, its living. How many of us on Earth consciously realize (let alone treat) Earth as a living and loving entity with a mind and soul of its own?
Anyway, back to drizzling. The way Earth handles the disturbances caused by actions of humans and also by the extra-terrestrial effects seem to be in such a way that, greater the disturbance, greater the tolerance it exercises. It's like an inverter circuit with an amplifier, wherein the input is the disturbance and the output is the tolerance. The disturbance is inverted into tolerance, multi-fold. To contain a disturbance of a given force, one needs tolerance of even greater force, isn't it? But then, how long can the tolerance continue to grow? There comes a time when this direct proportionality law is breached by the capacities of Earth, at one or the other level. That is when the Earth gears up to vent out its chaos, but again that too systematically. Now, one might ask why should the Earth endure such suffering to contain disturbances, when they need to be vented out some or the other day? Now, if the disturbances are vented out as it is, without processing them, as and when they happen, it's like not allowing life to happen, it's like allowing a pre-mature death to happen.
Death is inevitable, but if it happens at the right time, at a time when life is no more enjoyable and sustainable, it's no more death, but salvation. The human race might not know what Earth does in the background to allow its sustenance, but the pain and tolerance it takes, for the life to go on unperturbed by actions - be it of fellow people or of neighbouring planetary bodies, only the Earth must know. When a Tsunami executes on the outside, one either gets to experience the wrath in a split second or gets to enjoy the magnanimity of the destruction from a comfort zone, but to stomach such drizzle by containing the brewing trouble and simmering sizzle and perform the disaster management in such an earthly way remains to be the prerogative of Earth alone. No human can ever lay hands on such a distinguished responsibility.
