The Feb 27, 2010, M 8.8 Bio-Bio, Chile, #earthquake was caused by shallow thrust faulting along the Nazca and South America plates converging at 71 mm/yr. The fault rupture, over 100 km wide and nearly 500 km long, spread from 25 km deep, causing severe shaking and a tsunami. (1/3) #OTD ⚒🧪

MAJOR SPLIT-TYPE SUDDEN STRATOSPHERIC WARMING IN THE 06Z GFS! 🚨 🤯 Ok, it's at 330 hours, and it's just one member, so this is not a forecast. BUT, it's inescapable that forecasts are now drifting toward a weaker vortex, consistent with strong wave forcing from the Scandinavia-Greenland pattern.

A M5.8 (local confirmation); M5 .1 USGS. It occurred in Guayaquil-ECU at a depth of 84km and was an interplate EQ. It was a strong tremor due to its depth and epicenter. Also, I was at the epicenter and I confirm that it was strong as it was interplate and the first +M5 in Ecuador-2025

What happens in China never just stays in China. There is a surge in influenza A in the U.S. as well this winter. We rarely test whether the virus is conventional flu, or H1N1 swine flu, H5N1 bird flu. But the crowded ERs seen in many places are indications something is afoot. 🧵

Someone wrote to me, asking about the relative sea level rise at the time of the earthquake, visible in the tide gauge data at Port Vila. Two possibilities: either coseismic subsidence, or liquefaction that caused the coastal area to settle. The USGS indicates lots of liquefaction potential.

Woke up to my phone blaring and thought it was an earthquake early warning alert but no, it is a TORNADO warning. For San Francisco. WTF? I’m thinking our bathroom may be the best place to shelter as we don’t have a basement.
