EMSC shared this map:
Zachary Ross, a Cal Tech seismologist, has said that this is an aftershock after nearly a year. He wrote on Twitter: “Why is this considered a Ridgecrest aftershock after almost a year? Because the rate of events per day is still way above the rate before the sequence started.”
Dr. Lucy Jones, a seismologist, shared the same analysis on Twitter. She wrote: “Yes, an earthquake. A M5.5 at the very southern end of the 2019 Ridgecrest aftershock zone. This is a large late aftershock – do you remember that I said these are common?”
When Mayor Eric Garcetti announced the earthquake, which could be felt as far as downtown Los Angeles, he added: “As if things couldn’t get worse.”
The NOAA has noted that there is currently no tsunami warning, advisory, watch or threat in place.
