SANTA ROSA – Earthquakes of magnitude 4.4 and 4.3 jolted the North Bay on Tuesday night time, in keeping with the U.S. Geological Survey.
The earthquakes hit inside a minute of each other, with the magnitude 4.4 occurring at 6:39 p.m. about 2.4 miles north-northeast of Santa Rosa and the magnitude 4.3 at 6:40 p.m. about 2.3 miles north of Santa Rosa, the USGS reported.
The magnitude of the smaller was revised after initially being reported as 3.9. The quakes had been the most important in California since a 4.5 on Aug. 8 in Mono County.
Reasonable shaking was reported in Santa Rosa, and lesser results as far south as San Jose.
There have been no quick reviews of accidents or harm.
In keeping with the USGS, the earthquakes occurred on the Rodgers Creek Fault, a “potential right-lateral strike-slip fault.” The 2 most up-to-date reasonable sized quakes on the fault – a magnitude 5.6 and magnitude 5.7 – occurred close to Santa Rosa in October 1969.
The newest giant, surface-rupturing earthquake on the fault occurred between 1690 and 1824, and doubtless between 1715 and 1776, in keeping with the USGS. The 2003 Working Group for California Earthquake Likelihood estimated the recurrence interval between giant quakes on the fault as between 200 and 300 years.
The Rodgers Creek Fault hyperlinks up with the Hayward Fault beneath San Pablo Bay.
In keeping with the USGS, a break alongside the mixed size of the Rodgers Creek and Hayward faults might produce a significant earthquake of magnitude 7.4 — releasing greater than 5 occasions the vitality launched by the 1989 Loma Prieta quake, which had a magnitude of 6.9, brought on about $6 billion in harm and killed 63 folks.
