Tsunami Warning in Sonoma County: What You Need to Know and Do

Today, a tsunami warning was issued for coastal areas of California, including parts of Sonoma County, following a 7.0 magnitude earthquake off the coast of Northern California. This serves as a crucial reminder of the importance of being prepared for such emergencies, even in areas not traditionally associated with tsunami risks.

What Is a Tsunami Warning?

A tsunami warning means that a tsunami with the potential to cause significant flooding and strong currents is either imminent or already occurring. For those in affected areas, this is a signal to take immediate protective actions.

Immediate Actions to Take:

1. Move to Higher Ground
   If you're in a coastal area, evacuate to higher ground immediately. Tsunamis can strike quickly, and the first wave may not be the largest. Avoid low-lying areas and beaches.

2. Follow Official Alerts and Instructions
   Pay close attention to local emergency services, NOAA Weather Radio, or apps for real-time updates. In Sonoma County, SoCoAlert provides critical emergency notifications.

3. Stay Away from the Coast
   Even after the initial wave, dangerous currents and flooding may persist for hours. Avoid beaches, harbors, and rivers.

4. Evacuate Vertically if Necessary
   If you're unable to move inland, seek shelter in a sturdy building, moving to the highest floor or rooftop.

Prepare Ahead of Time:

1. Know Your Zone
   Familiarize yourself with tsunami hazard maps for Sonoma County. Understand which areas are most at risk.

2. Create an Emergency Kit
   Include essentials like water, food, first aid, flashlights, batteries, and important documents. Ensure your kit is portable in case of evacuation.

3. Plan Evacuation Routes
   Identify multiple evacuation routes and practice them with your family. Roads may be congested or impassable during an emergency.

4. Communicate Your Plan
   Share your evacuation plan with family and friends. Establish a check-in point in case you're separated.

What Makes Sonoma County Vulnerable?

While Sonoma County’s coastline is less tsunami-prone than areas like Crescent City, tsunamis generated by offshore earthquakes can still pose significant risks. Narrow bays and inlets can amplify waves, causing localized flooding and dangerous currents.

After the Tsunami:

1. Wait for the All-Clear
   Do not return to evacuated areas until authorities declare it safe. Hidden dangers like debris and contaminated water may remain.

2. Check for Damage
   Avoid buildings or structures that may have been weakened. Report any hazards to local authorities.

3. Stay Informed
   Follow local news and emergency updates for ongoing safety information.

Tsunamis are rare but potentially devastating events. Today’s warning highlights the importance of staying prepared and informed. By understanding the risks and taking proactive measures, we can protect ourselves and our communities.

Stay safe, Sonoma County!
