Yikes. Felt that one!

[San Francisco Department of Emergency Management @SF_emergency]

Hey SF, did you feel it? A 3.2M earthquake just struck 3 km South Southwest of Colma, Ca. Don't forget to drop, cover, and hold on when shaking starts. Take this as a reminder to get prepared. Visit http://

Elevated temperatures expected tomorrow in the Bay Area (Tuesday, 9/23). Cooling your home with open windows? Great idea! If you have kids or pets around, just make sure:
✅Windows can’t open more than 4 inches
✅Furniture kids can climb on is kept away from windows
✅Kids and pets are supervised around open windows
Remember, screens keep bugs out but don’t prevent falls.

A Heat Advisory from @NWSBayArea is in effect for San Francisco on Tuesday Sept 23 from 11 AM–7 PM. Temps in mid to upper 80’s are possible in parts of SF. Take steps to stay safe in the heat: https://t.co/8IKeUzG3hf

•Drink water and take breaks from the heat
•Open windows safely to prevent falls (use screens/guards, open from the top if possible, and always supervise children around open windows)
•Use fans to circulate air
•Check in with neighbors, especially older adults, people with disabilities, and those living alone.
•If your home is uncomfortably hot, consider visiting an air-conditioned space to cool off, such as libraries, shopping malls, community centers, or swimming pools. Visit https://t.co/8IKeUzG3hf to find a list of some public spaces with air conditioning and their hours.

To our Chief @SFPDChief Bill Scott. Thank you for your amazing service. Thank you for being colleague and a friend. Over the years and all of the emergencies, the pandemic, street work, countless pressers and events. I was always proud to stand by your side and work with you.🙏

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

Thank you @SheriffSF and Sheriff Miyamoto. You literally keep us safe at 911 everyday and we so appreciate you seeing the incredible work of our public safety dispatchers!

[SF Sheriff's Office @SheriffSF]

In what could be the scariest moment of our lives-- we dial three numbers on our phone and expect the person on the other end is an expert on everything… from first aid to burglaries and everything in between! #911 #dispatchers handle it all while staying calm. Happy National Public Safety Telecommunicators Week! Thank you #911dispatchers! #sanfrancisco #publicsafety #leadership #experts, #IAm911 #NPSTW, #ThankYou911 @SFDEM_MEC @SF_emergency

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

It’s my favorite week of the year. Dispatcher appreciation week!

[San Francisco Department of Emergency Management @SF_emergency]

April 13-19 is National Public Safety Telecommunicators Week. This week, we celebrate the invaluable contributions of the unsung heroes of San Francisco's emergency response system – our incredible 911 Public Safety Dispatchers.
Dispatchers work 24/7 to keep our communities safe. They are the calm voices we hear in our most urgent moments and the first link in the chain of emergency response.
When seconds count, these dedicated professionals coordinate critical resources across our city with precision and compassion. They're not just answering calls – they're saving lives every single day!
Join us all week as we highlight these amazing 911 heroes and the incredible work they do!

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

@SF_emergency 911 dispatchers have a very stressful job and they do it selflessly and around the clock working long hours. As we increase our staffing I am thrilled to be able to offer a space that is calm and quiet where they can take breaks and regroup to serve our City.

[San Francisco Department of Emergency Management @SF_emergency]

Today marks the grand opening of DEM’s wellness room!

DEM staff, including our 911 Dispatchers, Watch Center Specialists, and IT Operations work around the clock to keep San Francisco safe, making places to rest and recharge essential.

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

Earthquake! I felt that one. At first I wasn’t sure if it was the wind because we have some pretty good gusts blowing. An EQ is ALWAYS a good reminder to be prepared for ANY emergency.

[San Francisco Department of Emergency Management @SF_emergency]

Hey SF, did you feel it? A M4.2 earthquake just struck near Dublin. Don't forget to drop, cover, and hold on when shaking starts. Visit https://t.co/G7l1PZCbEn to learn about @myshakeapp and get early warning of strong shaking.

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

It’s such a pleasure to honor our people. Nicole is known for incredible expertise in all areas of 911 operations, her critical work on the CAD team but most of all for how much she cares about her colleagues. We are lucky to have you and so excited to celebrate you Nicole!

[San Francisco Department of Emergency Management @SF_emergency]

🎉Congratulations to Nicole Workman, the 2024 recipient of the Toni Hardley Award for Excellence in Supervision for DEM’s 911 Dispatch!

[San Francisco Department of Emergency Management @SF_emergency]

Public safety remains the #1 priority for Mayor @DanielLurie, @SFPD and all City departments. Residents & visitors will notice an increased presence of law enforcement around event areas to offer added layers of security & safety to ensure a welcoming atmosphere for everyone.

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

To my fellow surfer and favorite weather guy - thank you for your partnership and detailed weather predictions. We are grateful to you and the entire @NWSBayArea team for all you do - you are always there for us when we need you and we could not do what we do without you.

[San Francisco Department of Emergency Management @SF_emergency]

For #NationalWeatherpersonsDay we would like to send a special shoutout to Brian Garcia from @NWSBayArea ❕ We appreciate your insights and collaboration to keep us weather aware, while helping residents prepare for everything from tornados to tsunamis.

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

What a joy today to award Cathy Osorio Dispatcher of the Year! Cathy was nominated based on her response to complicated call while on radio. But Cathy has been a leader and example to many during a particularly hard year, facing it with strength and helping so many others.

[San Francisco Department of Emergency Management @SF_emergency]

Congratulations Cathy Osorio, DEM's Division of Emergency Communications Operations Employee of the Year for 2024❕

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

Yesterday @SF_emergency DEM emergency services division’s Jenny and Jackie started work for their deployment to @ReadyLA @LACity to support the EOC in planning and the joint information center. I know they will be a great support to the efforts down south. Thanks J & J

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

Lots of people felt that jolt this morning. That small earthquake is an important reminder. We need every San Franciscan who is able to take action to be prepared. At @SF_emergency we work everyday to prepare our City to respond and serve you when disaster strikes. @SF72org

[San Francisco Department of Emergency Management @SF_emergency]

Good morning 🌞 did you feel that? Take this as a reminder to get ready before the big one hits! You’re more prepared than you think you are - just take a few minutes to gather supplies and make a plan with your people.

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

We are with you Los Angeles

[San Francisco Department of Emergency Management @SF_emergency]

Our hearts may be in San Francisco, but today they’re with Los Angeles.

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

This night crew worked our EOC for evening mayoral inauguration activities. But as emergency managers our discussions, hearts & minds were with our colleagues in LA County. When you say the word, we will be there to support. Sending our love to you @CountyofLA @ReadyLA @LACity

[Mary Ellen Carroll (She/Her/Hers) @SFDEM_MEC]

The crew @SF_emergency is working tonight while the City celebrates. Thanks to our dispatchers, emergency managers, @SF_EMSA and all City workers keeping things sane. D-lok and I did our part to bring the sparkle to dispatch. Have a fun & stay NYE.
