We've gotten a number and array of videos--thank you!!--that people have shared to our Facebook feed. Thankfully there is no significant damage reported, likely because the earthquake was so deep, but people were certainly shaken thoroughly. Here's a scene from Palmer. https://bit.ly/43U8ks0

Although the timing and location may seem very coincidental, we are calling this NOT an aftershock of the 2018 Anchorage Earthquake. We are calling it the 2025 magnitude 6.0 Susitna Earthquake. This earthquake took place on the subducting Pacific Plate. We'll follow up as we learn more.
