We are proud to announce that we received a 2025 Esri Special Achievement in GIS award, which recognizes ALERTCalifornia’s layer that allows users to incorporate live camera views into maps, enhancing situational awareness before, during, and after natural disasters. Learn more: bit.ly/4oboYvJ

New cameras online: Verdi Peak Lookout 1 & 2 were recently added to ALERTCalifornia's network. Located at the historic Verdi Peak Lookout in Tahoe NF, the cameras provide emergency managers with views at this no-longer-staffed lookout. Watch live at: bit.ly/46SpxnK

New cameras online: Monument Peak 1 & 2 were recently added to ALERTCalifornia's ever-growing camera network and are located in the Laguna Mountains in San Diego County. See the view live at: bit.ly/44GnLop

Thanks for the shoutout! We are a research program based at @ucsandiego.bsky.social and our ever-growing network is up to 1,190 natural hazard monitoring cameras across the state. The public can see the same live views as emergency managers at cameras.alertcalifornia.org

First earthquake, then fire: UC San Diego researchers test steel building Drivers on Interstate 15 may have noticed smoke near Pomerado Road this morning. KPBS education reporter Katie Anastas says it was part of a UC San Diego study on how fire spreads through earthquake-damaged buildings.

Shake, rattle, and... burn? ALERTCalifornia's drone team collected data for recent @ucsandiego.bsky.social shake table experiments. The thoroughly shaken steel structure's upper floors were recently set ablaze to understand how fire travels through earthquake damaged buildings bit.ly/3Ur8Atf

New cameras online: ALERTCalifornia's Martis Peak 1 & 2 are located at the historic Martis Peak Lookout (built 1914). The cameras provide views of northern Lake Tahoe and the Tahoe NF. Our cameras support lookout staff and provide monitoring off-season. Live: bit.ly/46nFceQ 📸: nhlr.org

ALERTCalifornia cameras work hand-in-hand with lookouts, supplementing their efforts and helping keep watch during times when towers are not staffed. We are proud to support @calfire.bsky.social and lookout staff and volunteers across the state with our cameras.

ALERTCalifornia's field team has been busy and many new cameras are coming online. Some of the most recent are Knob Peak Lookout 1 & 2. They're located at the historic Knob Peak Lookout, which was built in 1932 in Shasta-Trinity National Forest. See the view live at: bit.ly/45eeUdQ

Good @alertcalifornia.bsky.social view of firefighters stopping the #OrchardFire near Capay on Friday.

Many of ALERTCalifornia's scientists are based at @ucsandiego.bsky.social's @scrippsocean.bsky.social and we are looking forward to welcoming our new director.

Congratulations to our partner @calfire.bsky.social! This award is much deserved. We are proud to support you with our live cameras streamed in ECCs and through our ArcGIS map layer, which allows users to incorporate ALERTCalifornia's camera network into any Esri map.

Congratulations! We are proud to partner with CAL FIRE and provide ALERTCalifornia's cameras as an Esri GIS map layer to support your efforts.

Engineers Shake Tallest Steel-framed Building Ever Tested on an Earthquake Simulator A 10-story, 100-foot structure was experiencing simulations of real earthquakes, including the 6.9 magnitude, 1989 Loma Prieta temblor, as part of an effort to determine if height limits for buildings...

ALERTCalifornia researchers recently collaborated on a huge (literally) Englekirk Structural Engineering Center shake table experiment. Our team collected drone and sensor data during the two weeks of earthquake simulations run on this 10-story, 100-foot structure. @jacobsschool.bsky.social

It's no haboob rolling across Central California's Carrizo Plain tonight, but smoke from the Madre Fire that's currently scorching this National Monument. Fire is a natural process in this critical ecosystem, I think, so I hope it recovers soon. @alertcalifornia.bsky.social McKittrick Summit cam.

Sunset and the evening time-lapse of the #MadreFire in San Luis Obispo County on 7/3 from ALERTCalifornia's McKittrick Summit North camera. Check current conditions at: bit.ly/4ex8Vnr. Look to CAL FIRE San Luis Obispo Unit and San Luis Obispo County of Office of Emergency Services for updates.

The graphic from CAL FIRE urges people to no spark a wildfire this 4th of July.

🔥🔥 Don’t Spark a Wildfire this 4th of July 🔥🔥
Since 2024, fireworks have caused over $35 million in property damage across California and sparked 1,230 fires.

Madre Fire Compilation: San Luis Obispo County Multiple time-lapse videos captured on ALERTCalifornia's cameras of the Madre Fire in San Luis Obispo County, CA. These clips show the start and afternoon growth of the Madre Fire on July 2, 2025. The time-lapses have been sped up. Watch UC San Diego's ALERTCalifornia network's more than 1,170 (as of June 2025) live monitoring cameras at cameras.alertcalifornia.org ALERTCalifornia's camera sensors can see 60-70 miles on a clear day and more than 120 miles on a clear night. These cameras provide emergency managers with the information they need to respond to and monitor hazards like wildfires in real time.

Based at the University of California San Diego, ALERTCalifornia is a public safety program working to understand wildfires and other natural hazards, and determine short and long-term impacts on people and the environment to inform management decisions. The state-focused program manages a growing network camera sensors, and collects data that provides actionable, real-time information to inform public safety. In addition to the camera network, and in response to increasingly frequent and severe climate-driven disasters, ALERTCalifornia is prioritizing novel data collection and research. These data are shared with fellow institutions and partners. Advanced technology offers fresh insight into the cascading disasters associated with wildfires, such as post-fire debris flows, floods, and erosion. These data will lead to a greater understanding of natural disasters and their long-term pacts on air, water, and soil quality as well as human health in California. Our multidisciplinary team is based at UC San Diego’s Jacobs School of Engineering, Qualcomm Institute, and Scripps Institution of Oceanography. We also work closely with partners like CAL FIRE across the state. Learn more at https://alertcalifornia.org

A Red Flag Warning is in effect for the interior Northern California through Tuesday evening due to thunderstorms & gusty winds.

These conditions dramatically increase the risk of rapid wildfire spread in the Northern coastal range, Shasta County Mountains, Southern Cascades, and Burney Basin.
