Is a massive tremor on the way? Ring of Fire activity returns as a series of earthquakes shake California and Alaska

A series of earthquakes shook the US yesterday with several hitting worryingly close to the Ring of Fire, sparking fears a massive tremor could be on the way.

The most powerful of this latest cluster – which also shook Alaska and California – came in Perry, Oklahoma, where a 4.3 magnitude tremor struck.

This follows on from a flurry of earthquakes in California at the weekend, with experts warning residents to ‘get those earthquake preparedness kits ready’.
