The County of Santa Clara to Participate in Nationwide Test of Critical Emergency Alert Systems

Test planned for Oct. 4 at approximately 11:20 a.m. will send messages to all cell phones, radios and televisions


SANTA CLARA COUNTY, CALIF. – The County of Santa Clara will participate in the nationwide test of the Emergency Alert System (EAS) and Wireless Emergency Alerts (WEA) on Wednesday Oct. 4 at approximately 11:20 a.m. The tests ensure that these critical emergency communication systems are still effective in alerting the public about emergencies, particularly at the national level. No action is needed from the public.

The national test will encompass two critical components: (1) WEA, which impacts cell phones and (2) EAS, which targets radios and televisions. 

The WEA test will be administered through FEMA’s Integrated Public Alert and Warning System (IPAWS) to cell phones across the country. The message will be displayed in either English or Spanish, depending on the language settings of the wireless handset. 

The message will read: 

  • “THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed.” 

Spanish-language settings will display: 

  • “ESTA ES UNA PRUEBA del Sistema Nacional de Alerta de Emergencia. No se necesita acción.”

The EAS test will last approximately one minute and will include radio and television broadcasters, cable systems, satellite radio and television providers, and wireline video providers. The test message will resemble the familiar monthly EAS test messages and will emphasize that it is only a test.
