Wildfires are coming and you need to get ready. That was the message state and local officials hammered home during a press conference earlier this month in Orange County, as part of Wildfire Preparedness week.

By analyzing how waves created by marsquakes travel through the interior of the red planet, scientists hope to better understand how it was created. That's what the InSight spacecraft was hoping for when the first-ever witnessed quake struck earlier this month.

Urban search and rescue workers from Los Angeles County and Fairfax, Virginia, met up in Castaic to practice how to respond to an earthquake. For 96 hours, they ran drills, including how to pull people from elevator shafts, collapsed parking structures and crushed cars.

"We strongly encourage people to plan as though no help is coming to get you."

Last night, residents of Ventura and Los Angeles counties got to experience their first thunderstorm in quite a while. If it's been raining so much, why haven't they come around more often?

Last night, scientists at the Jet Propulsion Laboratory in Pasadena, sent their final message to the Mars rover Opportunity, and unless they hear back it looks like the mission could be coming to an end after 15 years.

On Jan. 17, 1994, a 6.7 magnitude quake rocked the suburbs north of Los Angeles, leaving 57 dead and causing more than $43 billion in damage. Officials worry LA isn't ready for the next big quake.

High above the Cranston fire in Idyllwild, there are giant, dark, pyrocumulus clouds. While they might look like thunder clouds, they're not bringing rain. In fact, they're bringing strong winds and the threat of lightning.

The Ferguson fire continues to threaten Yosemite, as it more than doubled in size over the past few days. The hot and dry conditions that've made it difficult to tackle the blaze have been present across other parts of the state, hinting at a destructive fire year ahead for California.

While we had a lot of precipitation last year, this year has been below average. What does that mean for our water supplies, considering we're only a year removed from crippling drought?

Before the storm made landfall earlier this week, it was forecast to dump 10 inches of rain in the Santa Barbara mountains. Where did all of that water go?

Atmospheric rivers are a vital source of California's water supply, but they also can trigger mudslides given their often heavy rains.
