As has been widely reported in a huge variety of ways, an earthquake swarm has been detected off America's Pacific coast. These shakes off the coasts of Oregon and California state serve to remind us that this entire region is tectonically – seismically and volcanically – active, but they in no way suggest a massive quake, a “Big Oneâ€, is imminent.
An earthquake swarm describes a series of tremors, created by movement along a fault line, that occur closely in time and space. They’re collections of shakes that can mean very different things depending on when, where, and how they appear, and what other geological “symptoms†they happen alongside.
