Sorena Sorensen passed away this month.

Sorena was a long-time curator at the National Museum of Natural History of the Smithsonian Institution. She was also an insightful and talented researcher who studied the role of fluids in metamorphism of subduction-related rocks. She also contributed to understanding the formation of jadeite and jade deposits.

I think I figured it out.

The mass delusion of this mass infection event.

I've told the story of how I got into #EmergencyPrep... Local govt held a community meeting about preparing for a 9.0+ #subduction zone #earthquake hitting the #PNW. Power co, water co, etc all gave useful advice.

Then the fire chief stood up there and said

"We're not coming to help you"

Shock from the audience...

Then the yelling ... 1/

Map of #philippines M7.6 #earthquake sequence (in purple) with mechanisms for largest aftershocks. The M6.9 was another #subduction interface event, but the M6.6 was not. #Aftershocks are located all the way to (and possibly past) the trench.
