Geo-targeting CMAS Messages

Should messages reference an alert’s geotargeted area?

Do message recipients need to know what areas are receiving an alert? For example, in a scenario where only a few city blocks have been targeted, is it important for recipients to know that they are being targeted that specifically? If so, how could this be done?

Need for performance metrics and goals

EMs have long asked for 'better' warning capabilities. The federal report, Effective Disaster Warnings, calls for 'more effective' warning capabilities. What specifically does 'better' mean? When is 'more effective' sufficiently effective? How does one make decisions involving technical risk and system functionality without such info?

How can we help alert originators generate effective messages?

What are the barriers to effective CMAS use by responsible officials, and how can those be reduced or eliminated?

 

Scope might include usability of alert origination tools, but also providing clear expectations and policy "top cover" for alert originators... most of whom will only issue a few public warnings in their whole careers.

What is the optimal CMAS text alert length?

The CMAS 90 character limit was set for somewhat arbitrary technical reasons and did not reflect any research into the actual effectiveness of short text alerts. Note that the answer may be different for different languages, and needs to accomodate unfamiliar as well as expected hazard-types. Note also that effectiveness needs to be defined in measurable terms, and may have multiple dimensions, e.g., convenience for ...more »

Public Response to CMAS Messages

How can we assess public behavior in real time?

This is a deep problem that goes not just to CMAS, nor even to Emergency Public Information generally, but to almost everything we do at response time, and a lot in mitigation, preparation and recovery as well. An added constraint is that these assessments must be and (even more challenging) must be perceived as legitimate activities by officialdom, lest they spark a political backlash. One key might be to make the ...more »
