We know tremors are inoffensive and harmless but, we only know if the tremor will be it, or it will show its real face as an earthquake, destructive and very dangerous, specially for the tsunamis that might occur afterwards. To feel that the floor is moving -doesn’t matter if main level or 19th floor- it is a feeling that can not compare to anything else. It not like a boat or a ship, and the sensation, even if nothing is falling from the walls and furniture, the sensation is breathtaking. That foment you to be flexible, adaptative, prepare for any time that a little tremor turns into a big, big earthquake, and you need to take care of your loves ones and be calm above everything. I think that is why PhD. Humberto Maturana, biologist, who came with the Autopoiesis concept on Theoretical Biology, was from Chile. The concept of adaptation and plasticity (with different names) are fundamental in this understanding of what means life.
But, above all, the happiness that you feel, every time there is a tremor of 5-something Richter scale or even 6 sometimes, that slowly reduces and stops, and not turn into a 10 minutes long 9-something earthquake, the happiness that you feel is infinite, and you feel that every time there is a movement that was a “ups, not today” from the Nazca and Antarctic’s tectonic plates against the South American plate.
