We're Live! Going to stream the Fireworks display at Quakes stadium, live on youtube with waveforms from a seismometer in close proximity! youtube.com/live/RrMSi1D9I…

For the #4thofJuly2025 we are trying something new. Tomorrow night at approx. 9pm we're going to attempt to LIVESTREAM the fireworks display and waveforms from a mobile seismometer at LoanMart Field (Quakes Stadium) in Rancho Cucamonga! If it all works out we'll be on youtube and…

June EQ history: A day that reminded Socal residents they live in EQ country was 6/28 when they were awoken by the M7.3 Landers event at 4:57am followed by M6.3 Big Bear 3 hours later. The Landers EQ was also one of the first eqs to be studied with satellite images using InSAR.…

Instead of #FieldPhotoFriday we're going to have an #OfficePhotoFriday! This week a group of folks in SCSN got together to see if they could spot a rocket being launched live from Vandenburg SFB on our new PQRS feed, turns out if you're looking at them at the right time, you…

Even the smaller earthquakes can make the news if enough people feel them. At 12:22 pm PDT a M2.7 occurred near Sherman Oaks. People right on top of it (in Universal City) felt it pretty well, while others a very short distance away likely did not! Even for these small quakes, a…

#AskCaltech works on answering your pressing questions, speaking with experts from the Caltech Community. Their latest video on earthquake prediction is a great watch if you've ever wondered - Why is predicting earthquakes so challenging (not possible)? Take a look and learn…
