Story summary

A magnitude 4.2 earthquake struck near Seattle, Washington, on Tuesday at 5:05 PM ET, causing noticeable shaking reported by over 5,000 people across the Puget Sound area, which includes Seattle, Tacoma, and Olympia. Although no injuries or major damage were reported, this seismic event occurred close to the Cascadia Subduction Zone, a fault feared to be overdue for a catastrophic magnitude 9.0 earthquake that could impact cities along the US West Coast. The last significant quake in the region was the magnitude 6.8 Nisqually earthquake in 2001, which caused extensive damage and injuries. According to the US Geological Survey, there is about a one-in-four chance of an aftershock stronger than magnitude 3.0 within the next day.

🔮 Pastor Joshua Mhlakela, a South African preacher, recently said he has calculated the exact time of the biblical event in which believers are lifted into the clouds to meet Jesus Christ, claiming that it will happen between October 12 and 13.
🔮 Reverend Mikey Noechel (Left) has been revealed as the Buddhist spiritual advisor who was present at Christa Pike's failed execution Wild Heart Meditation Center in Nashville, Tennessee The Daily Mail has learned that both Noechel and Wild Heart Meditation Center have opposed Pike's execution, citing Buddhist teachings which believe killing continues a cycle of violence which could have karmic consequences.
🔮 What I can say from the radar is that it is organized, it is structural, and a solid geological mass would not have returned such a strong signature.
🔮 The epicenter of Tuesday's quake was also near the Cascadia Subduction Zone, a major fault capable of producing powerful earthquakes and tsunamis that scientists fear may be overdue for a major rupture.
