Someone said something to me about writing the silence of this time. The quieting of traffic and human-made noise is, I suppose, what she meant. And then today I read this article about a sizable decrease in human-induced seismicity. There’s a prompt in there somewhere.
“The fall in noise could also benefit seismologists who use naturally occurring background vibrations, such as those from crashing ocean waves, to probe Earth’s crust. Because volcanic activity and changing water tables affect how fast these natural waves travel, scientists can study these events by monitoring how long it takes a wave to reach a given detector. A fall in human-induced noise could boost the sensitivity of detectors to natural waves at similar frequencies.”
