Hi! I’m Wendy and I’m an earthquake geologist and science communication specialist. I post about earthquakes, geology, cats, kids and comms.

According to BlueSky I’m a “delightful blend of scientific rigor and domestic chaos” 😁. 🧪⚒️

This link will take you to PHIVOLCS, the Philippines national institution dedicated to providing information on the activities of volcanoes, earthquakes, and tsunamis.

The seismic waves from the earthquake in the Philippines are rolling under us here in California. The earthquake waves are far too small to feel here but they can still be detected by sensitive seismic instruments!

Liquefaction triggered by this earthquake may be extensive in severity and (or) spatial extent.

Earthquake induced landslides are estimated to be significant in number and (or) spatial extent.

According to the USGS, more than 2.3 million people may have been exposed to very strong or severe shaking, and another 14 million may have experienced moderate to strong shaking. earthquake.usgs.gov/earthquakes/...

So far I agree that he resembles all the people y’all have suggested. But I’ve never seen any of those people so I don’t think that’s who I’m thinking of…

According to USGS PAGER, more than a million people may have experienced moderate, strong, or very strong shaking and 10 million more may have experienced light or weak shaking. Some damage is possible.
