I'm trying to figure out how to start 2025 in a positive fashion on social media. This year, I plan to write more, chat more, and talk science as often as possible.

Come for the cats, stay for the science.

Either way... more science! 🧪👩‍🔬

This post is not my usual science post. I have waited 11 years to share this poem. My sister, Lori, passed away on 11/11/14. Eleven was her favorite number, so it seemed appropriate to share today what I wrote following her death. medium.com/p/dear-siste...

I am not a microbiologist, nor do I play one online, so this should be educational for everyone!

Dear EVERYONE...

A-ha is NOT a one-hit wonder by any measurement. This is a hill I will die on. It's a pointless hill, but I will die on it.

FFS, go listen to "The Sun Always Shines on TV". It reached #20 in the US.

This is why I had to shift my walk to feed all the cats about a half hour earlier. Stupid axial tilt.
The sun is setting noticeably earlier now. It sets here 20 minutes earlier than it did 2 weeks ago. That changes the fastest at the equinox, which is in 3 weeks.

Watch the seismic waves from the magnitude 8.8 earthquake off the coast of Russia sweep beneath seismic stations in North America.

By the time the waves reached North America, they are far too small to be felt by people, but can still be detected by seismic instruments. 🧪

Crescent City having a forecast of 3-6 ft while further up/down the coast having a < 1 ft forecast is also one of these places where focusing makes a bigger local tsunami

⚒️🧪 Aftershocks happen when nearby sections of fault react to an earthquake.
The biggest ones can get to about a magnitude unit smaller than the main quake.
Kamchatka could have a M7.5 aftershock and that would be completely within the realm of expectation for a huge event like this.

Full video of the tsunami in Petropavlovsk-Kamchatsky, Kamchatka, Russia, following the 8.7 earthquake. Wave seems incoming and a few meters at least.

If you were in the vicinity of the #earthquake and are currently safe, please take a moment to report your experience for science.

You can also report later once your world isn't (literally) upside down.

PEOPLE. WHAT DO YOU DO WHEN AN EARTHQUAKE HAPPENS?

STOP.

DROP.

HOLD ON.

Don't go outside. Don't film everything falling around you. Get under a table or desk and hang on. Cover your neck and head as best you can.

Put on shoes if there is broken stuff around.

Normally, I share the earthquake itself, but since the region nearest the epicenter is "lightly populated", I want everyone to be aware of the tsunami possibilities. So if you are in a coastal area around the Pacific or Indian Oceans, please follow local instructions. 🧪
