Recently, some residents in Los Angeles County were startled by errant evacuation warning alerts on their cell phones. In response to this, the county's director of emergency management, Kevin McGowan, provided a detailed explanation of how the alert system operates.
McGowan explained that the system involves an interface where officials activate the type of alert to be sent, such as an evacuation order or warning, and specify the geographical area to be targeted. Once the message is initiated, it is transmitted to an integrated public and alert warning system aggregator, which then connects to various cell service providers through a cloud network.
