An expert has urged California residents to “remain alert” after a series of earthquakes struck the state within 48 hours as she warns the string of tremors could signal a larger earthquake to come.
The first earthquake, which measured a magnitude of 3.5 on the Richter scale, hit San Bernardino at 9.44 am on Monday and was followed by another 3.0 magnitude tremor just minutes later, according to the US Geological Survey. CalTech researchers said the second quake was an aftershock.
At 9.58 pm a third earthquake struck around 3.1 miles north-northeast of the Californian city at a depth of 5.1 miles. On Tuesday morning, a 4.1 magnitude earthquake then struck 26 miles from Ferndale. The quake occurred shortly after midnight at a depth of 12 miles.
It was followed by a 3.0 magnitude earthquake near Greenville at 19:12 pm before a 4.5 magnitude one was recorded near Ferndale at 20:32 pm. Dr Jess Johnson, associate professor in Geophysics at the University of East Anglia told The Mirror US: ” These earthquakes are fairly small and only a handful were felt by residents. The largest one so far, a Magnitude 4.5 at 2025-02-12 04:32:40 (UTC), was reported to be felt by less than 200 people and had a weak shaking intensity of III (three) out of X+ (ten or more).”…
