Wallace Creek is located along the San Andreas Fault in central California. Wallace Creek flows across the fault. Sideways sliding (right-lateral fault motion) of the San Andreas has moved Wallace Creek (to the right, if you imagine standing on one side of the fault and looking across at the other side) several times and evidence of these offsets is preserved in the landscape.

Throwback to hanging out at one of the most famous fault locations in the world - Wallace Creek.

The 1st image is of me standing near the current location of the creek on the downstream side of the fault. The 2nd image is a lidar image from OpenTopography of the fault with the location where I’m standing in the 1st image marked by an ❌.

This excellent video from @novapbs talks about earthquakes in the Pacific Northwest, including the #earthquake in 1700. Plus, I talk about how earthquakes are like 🍪 so it’s extra sweet 🙂

📺 If you missed it the 1st time, you can tune in tonight (January 8 at 9 ET) to learn more about the San Andreas and Cascadia Subduction zone.

You’ll also see some familiar faces, including me and @seis_matters! 🤗

This data is from Station Monitor, which is available as a free app or webpage from @EarthScope_sci.

Click on any seismic station to see near real time seismic data!

Always check the scale! Seismic waves attenuate, or get smaller, as they move away from the quake location, so unless you are close to the earthquake you won’t be able to feel any shaking BUT seismometers will be able to measure the slight movement.

The waves from the M7.0 earthquake near Vanuatu are passing under me on the east coast of the US right now!

Look carefully at the scale on the 2nd image - by the time they reach VA these waves are about 1/2 the width of a human hair (too small to feel).

Image 1: seismic data from a seismic station near Fredericksburg, VA.

Image 2: more information about the seismic waves recorded at that station, and the distance between the station and the earthquake.

Image 3: seismic station location.

Seismic trace which has data from a seismometer moving across timed lines from left to right. A purple dot indicates the arrival of the earthquake waves which are small until the surface waves arrive, which create a large wiggle pattern on the graph.

Zoomed in view of the waves from the earthquake is across the top. At the bottom of this image is a map showing the location of the earthquake in the path of the seismic waves where they reach the seismometer in Virginia.

Each dot is an earthquake. The color of the dots indicates the depth of the earthquake. In the video above, you can see that, for the most part, the earthquakes outline the subduction zone, where one plate is sliding beneath another as they come together.

There was a M7.0 near Vanuatu today.

This area is REALLY seismically active - in fact, 5 of the 11 M7+ quakes of 2022 occurred in this region.

The eastern margin of the Australia plate is so sesimically active due to high rates of convergence (slamming together) between the Australia and Pacific plates. You can view earthquakes in this area (and around the world) in 3D using the IRIS Earthquake Browser, like I’ve done here.

This video is a 3-D image of the earthquakes in the region that is being rotated about the central axis so you’re looking inside the Earth with a surface towards the top. The color scheme of the Earthquake dots is the same as in the last image with purple earthquakes, being shallow and red earthquakes, being the most deep. this shows how there is a steep subduction zone that is outlined by earthquakes.

Why am I tired you ask?

In 2022 I adopted a child, traveled to Guatemala & Australia (+San Diego, Pittsburg, Denver, Boulder, PHX, Dallas and Chicago), was in the hospital twice, lost an organ, went to 5 conferences, did 2 panels at Comic Con, filmed with Discovery, was on the Today Show, gave 50+ talks & 30+ interviews, changed jobs, was featured in a 📕 book, met my statue (in DC and in Dallas), my cat went viral on TikTok (twice) and there was some other stuff in there too.

The #earthquake waves from the M6.4 #Ferndale quake were recorded by seismic stations across North America. By the time the waves moved away from the region where the earthquake occurred they were much too small to feel but not too small to be measured by seismometers.
