Earthquake alerts on Nextdoor

Since launching Nextdoor Alerts as part of the New Nextdoor in July 2025 with The Weather Company, Samdesk, and PowerOutage.us, the platform has delivered 3.7 million alerts – an approximately 400% increase in alerts delivered since launch. Neighbors can comment on these alerts and have real-time conversations, keeping each other informed. New partnerships with organizations like Waze and integrations with USGS demonstrate Nextdoor's sustained investment in essential neighborhood information. To date, the most engaged alerts measured by neighborhood conversations include dual Tsunami Watches for Orange County and San Diego County coastal areas on July 29, and most recently, a magnitude 4.03 earthquake near San Ramon, California, on December 14.

"We know that Nextdoor plays a critical role for neighbors before, during, and after disasters," said Nirav Tolia, CEO and Co-Founder of Nextdoor. "Integrating with USGS alert data exemplifies our continued commitment to providing reliable, real-time safety information to help neighbors make informed decisions and connect with neighbors.”

USGS Integration Delivers Neighborhood-Specific Disaster Data

Nextdoor neighbors will receive earthquake alerts that affect their neighborhood in real time. The alerts appear at the top of the Nextdoor newsfeed and are delivered via push notification if they are severe enough. The key difference between receiving an alert via Nextdoor or other alert providers is the ability to converse with your neighbors about the alert information. After neighbors receive the alert, they can use Nextdoor to check on neighbors, offer resources, and share real-time local information.

Alerts Map for Public Agency Partners

Nextdoor Alerts Map is also now available for public agency partners. The Nextdoor Alerts Map displays real-time information from Nextdoor’s alerting partners using Nextdoor’s API. These range from everyday alerts on weather, traffic, and public safety to critical alerts on power outages, severe weather, earthquakes, and fires.

Agencies can actively engage with their communities through the Nextdoor Alerts Map by monitoring alerts in their area and participating in real time. Officials can react to alerts, respond to neighbor questions with clarifying information, share links to official agency posts for ongoing updates, and reshare alerts to amplify or provide additional context.
