Chapter 31. Recognizing Rumors, Misinformation, and False Authority
During a wildfire, earthquake, flood, hazardous-material release, power outage, or evacuation, residents naturally want immediate answers. When official information is limited or conditions are changing quickly, rumors can fill the gap. A forwarded voice message, dramatic screenshot, unofficial evacuation map, or confident neighborhood post may appear credible even when the information is incomplete, outdated, or false.
Residents of Pleasanton, Dublin, Livermore, San Ramon, Danville, Sunol, and surrounding Tri-Valley and Bay Area communities should learn how to evaluate emergency claims before believing, acting upon, or sharing them. Good intentions do not make information accurate, and confidence does not establish authority.
Trace Every Claim to Its Original Source
The person who sent a message is not necessarily its source. A neighbor may forward a screenshot received from another group, whose members obtained it from an unidentified social-media account.
Ask who originally issued the information. Reliable emergency instructions generally come from identifiable agencies such as:
- A city or county emergency-management office
- A fire department or law-enforcement agency
- CAL FIRE or Cal OES
- The National Weather Service
- A county public-health department
- Caltrans or a local transportation authority
- An electric, gas, or water utility
- An authorized school, workplace, or care facility
Look for a direct link to an official website or verified agency account. A government logo copied into an image does not prove that the agency created or approved it.
Examine Screenshots Carefully
Screenshots are easy to forward and difficult to evaluate. They may omit the original account, publication date, location, link, correction, or subsequent update. They can also be cropped, altered, or taken from an unrelated incident.
Instead of relying on the image, visit the agency’s official website or account and locate the original notice. Confirm that the message applies to your location and remains current. If the original post cannot be found, do not treat the screenshot as an official instruction.
When sharing legitimate information, forward the direct official link whenever possible. This allows recipients to see later corrections and updates.
Treat Voice Messages and Secondhand Reports Cautiously
A voice recording can sound convincing because the speaker communicates urgency, emotion, or apparent personal knowledge. The speaker may claim to know a firefighter, police officer, city employee, utility worker, or person inside an emergency operations center.
Such claims are difficult to verify. Even if the speaker genuinely spoke with someone involved, the information may have been misunderstood, repeated without context, or overtaken by changing conditions.
Statements such as “my friend at the fire department says,” “someone at City Hall told me,” or “I heard the road will reopen soon” should not replace a public announcement from the responsible agency.
Secondhand information may alert residents to something worth checking, but it should prompt verification—not immediate redistribution.
Be Careful with Unofficial Maps
Community-created maps can help residents discuss landmarks or understand general geography, but they must not be confused with official evacuation, road-closure, fire-perimeter, flood, or hazard maps.
An unofficial map may:
- Use boundaries that authorities never issued
- Combine information published at different times
- Display an estimated fire perimeter as a confirmed boundary
- Omit closed roads or dangerous conditions
- Remain online after an order changes
- Use colors that resemble official warning zones
Never decide whether to evacuate, remain home, reenter an area, or choose a travel route solely from an unofficial map. Consult the current map or notice published by the agency managing the incident.
Recognize False Authority
False authority occurs when someone creates the impression that they officially represent, direct, advise, or coordinate with public-safety agencies without authorization.
Warning signs may include a person who:
- Calls themselves a community emergency coordinator without an identified appointment
- Claims to speak for firefighters, police officers, city employees, or emergency managers
- Issues unofficial instructions to evacuate, remain home, return, or use a particular road
- Directs residents to ignore an official order
- Uses photographs with responders as proof of an official role
- Wears unofficial clothing or displays agency-style logos
- Collects money or supplies while implying agency approval
- Claims exclusive access to information that cannot be confirmed publicly
- Pressures residents to follow them rather than official sources
A photograph with firefighters, an elected official, an emergency vehicle, or a command post does not establish authority. Neither does volunteering, serving on a neighborhood committee, knowing a public employee, or posting frequent updates.
Residents may summarize official information, but they should identify the source and avoid presenting themselves as authorized spokespeople. Impersonating an official or interfering with emergency operations can create serious danger.
Distinguish Mistakes from Deliberate Deception
Not every inaccurate message is intentionally deceptive. A resident may share outdated information without realizing it. Another person may misunderstand an alert or confuse an evacuation warning with an evacuation order.
Correct inaccurate information calmly. Provide the current official link and explain what changed. Avoid personal attacks that may distract from the safety issue.
However, repeated claims of special authority, deliberate alteration of official notices, fabricated instructions, fraudulent fundraising, or encouragement to violate emergency orders should be reported to the appropriate platform or agency. Call 911 only when the conduct creates an immediate danger or involves an active emergency.
FEMA recommends consulting trusted sources and avoiding the spread of unverified disaster claims. Its rumor-response guidance explains how misinformation can circulate during emergencies. Residents should also understand the official warning methods described by Ready.gov.
Pause Before Reacting or Sharing
Urgent language such as “share immediately,” “they are hiding this,” or “do not wait for officials” is not evidence. Before forwarding a claim, check:
- Who originally issued it? Identify the responsible agency, not merely the person who forwarded it.
- When was it issued? Confirm the complete date and time, including whether a newer update exists.
- Can it be confirmed through a current official source? Look for the same information on an official website, alert system, or verified agency account.
If verification is not possible, label the information as unconfirmed or, preferably, do not share it. During an emergency, an inaccurate message can send people toward danger, obstruct evacuation routes, overwhelm responders, or convince residents to ignore lifesaving instructions.
Helpful Hint
Ask three questions before sharing: Who originally issued it? When was it issued? Can it be confirmed through a current official source? If any answer is unclear, pause and verify.
Important Safety Reminder
Never disregard an evacuation order, shelter-in-place instruction, road closure, public-health notice, or utility warning because an unofficial person claims to know more. Follow current instructions from authorized agencies and report anyone impersonating an official or creating an immediate public-safety danger.
Important Preparedness and Safety Notice
This chapter provides general preparedness education, not real-time emergency instructions. Conditions, evacuation zones, routes, shelters, road closures, and public-safety directions can change rapidly. During an emergency, consult current information from authorized public agencies and follow all instructions issued by emergency officials. Call 911 for an immediate threat to life, active fire, serious injury, crime in progress, or another urgent emergency.
