Beings emergencies and disasters vary widely our alerting systems must be diverse in order to meet the needs of the particular situation.
Each of the warning methods have specific benefits and limitations

Let's review the major types of alerts that can be launched within Clark County. Each of these warning types can be used independently or in conjunction with each other. Emergency management officials and key stakeholders work together to identify the best fit for the situation.
Emergency Alert System (EAS)
EAS alerts are immediate, widespread, and cover the whole county. Beings Clark County shares the broadcast market (TV channels) with the entire Portland and SW Washington region, EAS alerts cannot be limited to a single county or city. When an EAS alert is issued the entire region will receive the message.
These alerts broadcast on:
- NOAA weather radios

Emergency Community Notification System (ECNS)
These alerts are used for a wide range of local emergencies, including:
- Missing people
- Criminal threats
- Chemical spills
- Boil water notices
Land-line phone numbers in Clark County are automatically included in the system. You must self-register cell phones, email addresses, and VoIP (voice over internet) to receive additional alerts.

Wireless Emergency Alerts (WEA)
WEA are text type alerts that can be sent to most newer smart phones within a geographic area. Alerts are based on your current location, not your home county or address associated with your cell phone. These messages have a unique tone and vibration. This short message will give immediate advice.
