We are primed for unusual coinciding strangeness. That sounds about as far from a scientific statement as you can make.
The danger is that with all the other ongoing geopolitical drama and noise we miss opportunities where otherwise we’d have gotten people out of the way. Adults need to be minding the store. Even if that rules out the #US entirely at this point…

Map of historical seismicity near today’s M6.2 #earthquake in western Turkey.
This event may have occurred on the Marmara fault segment of the North Anatolian Fault, thought to present a significant hazard to Istanbul.

Many people in and around the Italian city spend the night on the streets and in their cars, fearing aftershocks.

I made a quick #map of historical #seismicity for the region of today’s M7.6 #earthquake near the Cayman Islands. This left lateral strike slip event occurred on a #fault system that produced a few similar events in size & mechanism in the last decade.
(Good to see that USGS NEIC is still online!)

Large magma bodies found beneath dormant volcanoes, surprising scientists

New Cornell University led-research challenges the long-standing belief that active volcanoes have large magma bodies that are expelled during eruptions and then dissipate over time as the volcanoes become dormant.

Deep beneath California's Sierra Nevada, Earth's lithosphere may be peeling away

The processes that form continental crust from the denser basaltic rocks of the upper mantle may make the lower lithosphere denser than the underlying mantle. One theory holds that the lower lithosphere splits away and sinks into the mantle in a process called foundering. Conclusive evidence of foundering, however, has been hard to come by.
