Do you mean something like a Massive Solar Storm, which leads to an Electrical Grid Black Start with Nuclear power stations going the way of Fukishima, the solar storm geomagnetic anomaly initiates the 9+ Cascadia Subduction Zone earthquake along the whole fault line leading to Tsunami along most of western coast of the USA. From this event there is increased volcanism resulting in a couple of Mount St Helens events and of course not forgetting a Caldera event at Yellowstone, the release of the magma bubble pressure then initiates the Madrid fault Earthquake resulting in a 8.5M on the same day as the side of the Cumbre Vieja slips into the North Atlantic and the Banks decide to have a months Bank Holiday!

Now, whats the chances of that happening?

Edit, Did I mention the Asteroid or another Clovis Comet?
