Denis Gusty, the Alerts & Warnings program manager at DHS S&T, explained that CMAS will disseminate three primary types of messages: presidential messages; America's Missing: Broadcast Emergency Response (AMBER) Alerts; and alerts regarding imminent threats to life and property to specific, geo-targeted, areas across the nation.
This capability will be available to support local, state, tribal, and territorial alert and warning authorities.
Alerting authorities will use the Common Alerting Protocol (CAP) standard to disseminate their messages for the public, via the IPAWS Alert Aggregator.
The IPAWS Aggregator will disseminate the message to citizens, making them accessible via several communications channels, including television, radio, mobile phone, internet, public signage, etc. "Ideally,", Gusty
said, "CAP should allow an emergency manager to type a single message into a system that can push it through multiple media channels at once, including social media."
Aware of the increasing popularity of social media as a form of communication during emergencies, Gusty
team are developing best practices for the integration of social media into the IPAWS
is leveraging another DHS S&T
resource, First Responder Communities of Practice (http://Communities.FirstResponder.gov), as a centralized virtual location for the project team to store and share best practices that are collected and developed with partners across all levels of government.
For example, the project team is currently using a wiki within the "Make America Safer through Social Media" Community of Practice to document best practices gleaned from interviews with public safety professionals across the country, to share and store case studies and recommendations, and to develop a roadmap for how social media fits into the alert and warning domain.
explained that emergency managers see great potential for social media as a two-way form of communication with the public.
"It's more than pushing out a message," he
"The emergency managers want the public to be able to provide information back - such as report of wildfires to these officials, who can then inform the broader public through a trusted communications source."
An added benefit of using First Responder Communities of Practice is that through the site, programs such as IPAWS
can connect with similar efforts around the country.
For example, the DHS Virtual Social Media Working Group
(VSMWG) uses the site's wiki capabilities to collaborate and build a social media framework for first responders interested in using social media technologies in their organizations.
sees the knowledge base the IPAWS
program is creating regarding the role of social media in alerts and warnings as a component of this larger framework.
Gusty hopes to leverage the expertise of VSMWG members to inform the development of the alert and warning architecture so that the architecture meets the requirements of those who will use the technology in the field.
"The original intent of emergency broadcasting was to blast these messages out," Gusty
said, "but we know from talking to first responders that preparedness issues are a huge component as well.
