Mysterious Severe Ground Condition Pattern Jan 2023

Exactly one year after a major earthquake shook the region in northern California, on December 20, 2022, a magnitude 6.4 earthquake once again hit the area. Despite monitoring the region for 365 days, Earling's Severe Ground Condition models did not detect any high-risk time-windows (a period of 2 weeks) leading up to the event. However, just a few days after the December 20th earthquake, the Severe Ground Condition models detected a high-risk time-window in the same region, marking the first high-risk time-window of 2023.

M 5.4 - 15km SE of Rio Dell, CA Earthquake

On December 14, 2022, the Southern California Earthquake Center received an alert from Earling's exclusive Severe Ground Condition models indicating a high-risk seismic time-window in the region. As predicted, a M6.4 earthquake occurred near Ferndale, California on December 20, 2022. A few days later, a M5.4 earthquake was recorded in Rio Dell, near the epicenter of the previous earthquake. We believe it was an independent event not an aftershock of the last December 20 earthquake. About 200,000 were affected somehow with the event.
