To assess the effectiveness of NOAA/National Weather Service's (NWS) Tsunami Warning System, this survey is needed to gather specific feedback following testing of the associated NWS communications systems. Tests are planned annually March/April and September. Post-test feedback will be requested from emergency managers, the media, law enforcement officials, local government agencies/officials, and the general public. This is a web-based survey. Responses will be solicited for a limited period immediately following completion of this test, not to exceed seven days. This web-based survey will allow for efficient collection of information regarding the effectiveness of the Tsunami Warning System.
The original request for approval of this survey was based on NWSÂs conducting one Tsunami Warning Communications Test per year. Changes are as follows:
 This request for renewal now assumes that NWS (Western Region) will be conducting two such tests per year.
 Based on recent test response numbers, the estimated test respondent total has been adjusted downward to 250 from 340, with approximately 125 expected to respond to the first survey and all 250 expected to respond to the second. Thus, a net increase of 35 responses (up from 340 responses expected for one survey per year in the previous request) results in a small increase of 2 hours burden for survey responses.
 One hundred twenty additional responses and 16 hours originally estimated for follow-up regarding communications/technical problems are now considered not to be needed.
Summary: There is an overall decrease in respondents (250, down from 400), responses (375, down from 460) and hours (31, down from 45).
