There are several areas in California that are prone to earthquake swarms, hyperventilating because this swarm is at the tail end of the San Andreas is like running in the street and screaming we are all going to die. The swarm on the fault running through Ridgecrest is/was much more severe. The swarm at The Geysers, CA never stops and no doubt Mammoth Lake will start swarming again, so what? it’s California and part of our everyday life, embrace it and don’t fear the Reaper.
The only one hyperventilating is you over imagined hyperventilating.
Relax, have a drink.
