California insurance town hall this afternoon - just catching it after getting home from inspecting homes for wildfire risks. But not only do I talk about preventing home ignitions, I share the good news that home hardening increases your home's chance of surviving by a whole lot!

I once created a flowchart in English of the Environmental Impact Assessment process for building a factory in the People’s Republic of China…back in the day when it was published only in Mandarin.

This is center stage in the ladies room at work, about 6 feet by 8 feet big. I am a RCRA-CERCLA gal, not a NEPA gal, but I venture to say this is harder.

I've been monitoring FEMA's processing of disaster declarations after a long pause in the spring. This is the time of year when we start to get an uptick.

Right now the projections for Hawai’i are that initial waves will be 1 meter but secondary waves could be 2 or more meters. Quite a bit less than what we saw at the Fukushima Daiichi Power Plant - GE engineers videotaped 30+ meter waves in 2011.

I see that PG&E is starting to use their alerts more strategically. I really appreciate not only the additional insight into why an outage occurred, but also a link to their EPSS page that has been a game changer for quickly cutting off energy to distribution lines in high wildfire risk areas.

What happens when the insurance companies and catastrophe modelers stop getting data that’s generated by our tax dollars and US science and research institutions? Most of the data shown below is funded by federal dollars.

Jennifer Homendy #NTSB: "We have determined that the existing separation distances between helicopter traffic operating on Route 4 and aircraft landing on Runway 33 are insufficient and pose an intolerable risk to aviation safety by increasing the chances of a mid air collision at DCA."

Only the inland counties were issued yesterday. Here’s the change for my county. Because these are LRA changes, they affect homes and businesses in urbanized areas.

The number of destroyed schools in the Los Angeles fires is discouraging. In addition to the 5,634 students displaced, these facilities provide so many other services to the community. #CAFire

What's it like to volunteer for @WatchDuty? Amazing group of people who have been through fire professionally and personally, and we get to push buttons and spin dials on the most elegant app I've ever used.

We included disclosure requirements for data providers in the new ASTM property resilience assessment standard to address these major concerns and complexities. Many providers are not playing ball.

Going from fire to flood just like that. Backyard is flooded in #PlumasCounty so time to pay attention. I like to monitor #OrovilleDam inflows to get a picture of our watershed. More worried about Butte County right now, frankly.

Watch Duty expanded to Hawai'i last week and we're reporting on wildfire incidents like this brush fire yesterday afternoon on Maui near Ma'alaea. This ex-local haole is very honored to be part of the reporting team.
