I'm not about the spend a century-and-three-quarters or so to read the book, so perhaps my question about it is irrelevant, but here it is: how can a relatively small part of the Earth, that in which the epicenter occurs, often many miles below the surface, manage to affect an atmospheric layer that is above both the weather layer (troposphere) and the ozone layer/stratosphere/mesosphere without simultaneously causing a signal of *some* sort that just about everybody and their brother, in this highly instrumented and electronified age, can pick up?
About a year ago, I was waiting in a transportation hub rather late at night, when things had quieted down, and thus the train, when it passed through the building level below us, was quite noticeable. I swear I am not making this up: Right after that, a Japanese man strolled into the room and asked if we had felt the earthquake.
