Brief survey of 2011 tsunami warning products focus group participants

Brief Survey of 2011 Tsunami Warning Products Focus Group Participants

Preliminary Findings

January 27, 2013


Distribution of survey respondents

Distribution of Survey Respondents

  • Coronado, CA 7.7%

  • Kauai, HI 30.8%

  • Kodiak, AK 15.4%

  • Long Beach, WA 7.7%

  • New Hanover County, NC 15.4%

  • Seaside, OR 23.1%

    There were no responses from American Samoa and the US Virgin Islands.


Question posed

Question Posed

  • Is it helpful to post tsunami travel time information in tsunami messages, bulletins, and statements when no tsunami is expected?

  • Why?


53 8 of respondents answered no

53.8% of respondents answered:“No”

  • Why?

    • The information regarding hazard warnings should be kept applicable. If no tsunami is generated, then the added information is not needed.

    • Messaging needs to be timely and not include education relevant to other scenarios.

    • Providing travel times for tsunami’s that are not expected will create confusion.

    • It could create the false impression that a tsunami would occur.

    • Over time, it may deemphasize the differences in messaging, i.e. “the boy who cried wolf”.


46 2 of respondents answered yes

46.2% of respondents answered:“Yes”

  • Why?

    • It would prevent the need to cross-reference reports.

    • Even with no tsunami present, there may be surges that Water safety officers need to prepare for.

    • This would allow people to get used to seeing the graphics and information that they would otherwise only see during a tsunami warning. As it may be years between warnings, the delivery of this information would help people prepare for warnings.

    • It is preferable to have all information available to improve situational awareness and would be useful for planning and drill purposes.


Tsunami advisory

Tsunami Advisory

  • Tsunami Advisories do not trigger the same level of public notification within the Tsunami Warning System as do Tsunami Warnings and Watches.

  • This has resulted in incomplete information about what life-safety actions are needed by coastal residents and critical facilities, such as ports and harbors, within communities.

  • Currently, the Emergency Alert System (EAS) and National Oceanic and Atmospheric Administration (NOAA) weather radios do not easily support tone activation for public alerting during Tsunami Advisories.


January 2013 nthmp warning coordination subcommittee meeting

  • A multi-disciplinary team has recommended the use of the Local Area Emergency (LAE) EASevent code to activate the Emergency Alert System and provide audible alerts over NOAA Weather Radios when a National Weather Service Tsunami Warning Center issues a “Tsunami Advisory”.  See the definition of the LAE below. The following scenario outlines how the proposed approach, if implemented, would fill the current gap in reception of Tsunami Advisories through the EAS and NOAA Weather Radio components of the United States Tsunami Warning System:  Television and radio stations that participate in EAS broadcasting would have their programs interrupted by the issuance of an LAE.  The crawler on televisions will say, for example: "The National Weather Service has issued a Local Area Emergency on behalf of the State of Oregon for Josephine and Curry Counties".  This would need to change to reflect local county distinctions. The voice portion of the EAS activation and the voice that is heard on NOAA Weather Radios will explain that a Tsunami Advisory has been issued and provide the appropriate further information for the event. The voice message would also be heard on AM and FM radio stations.


January 2013 nthmp warning coordination subcommittee meeting

  • The following actions would need to be completed prior to use of the LAE code for Tsunami Advisories: 1. Local Emergency Alert System Coordinating Committees (LECC) and State Emergency Alert System Coordinating Committees (SECC) need to approve this use of the LAE.  It is anticipated that this proposed modification should not be difficult to implement since analysis of the meaning and uses appear to clearly fall within the scope of intended uses for the LAE event code.

  • 2.  National Weather Service offices serving areas for which this solution is desired by their state and local partners will need to modify their local procedures and software to support the issuance of the LAE event code whenever a Tsunami Advisory is issued. Since an automated method of issuing tsunami products is very near completion, we anticipate this will be a relatively simple modification. Please note the LAE is an event code that is for initiation by state and local entities; therefore, any issuance by a National Weather Service office assumes that they have a pre-arranged agreement to issue an LAE on behalf of a state or local entity. The narrative that is provided with the LAE will indicate that its issuance by the NWS is on behalf of some state or local entity.

  • 3. Television and radio station engineers will also need to make sure their equipment is programed to properly pass through the LAE event code automatically upon receipt.  Ensuring that this is accomplished for all TV and radio stations in a given area can be a significant effort.  Since this is already an operational EAS code, however, it is envisioned that most EAS decoders are already prepared to process the LAE properly. 


January 2013 nthmp warning coordination subcommittee meeting

  • Local Area Emergency (LAE). An emergency message that defines an event that by itself does not pose a significant threat to public safety and/or property.

  • However, the event could escalate, contribute to other more serious events, or disrupt critical public safety services. Instructions, other than public protective actions, may be provided by authorized officials.

  • Examples include: a disruption in water, electric or natural gas service, road closures due to excessive snowfall, a potential terrorist threat where the public is asked to remain alert or the issuance of a Tsunami Advisory.

January 2013 nthmp warning coordination subcommittee meeting

  • Evacuation Planning Playbooks

  • Secondary evacuation zones that could have been utilized during the Warning-level 2011 Tohoku-oki tsunami in CA (and 2012 Haida Gwaii tsunami in HI)

  • Lines/Zones of evacuation from large Advisory events, small/medium Warnings events, and scenarios where short-time time for evacuation (local, Cascadia, Aleutians/Alaska)

  • Playbooks can be used for exercises and/or incorporated into evacuation planning for non-worst-case events

  • Presented idea to NTHMP MMS and MES in July 2012

  • 25% of coastline is complete in CA

  • Recent supplemental information: NOAA Sea-Level Rise viewer

  • Monterey; 1m, 2m, 3m, and 4m elevation lines at Mean High Water


January 2013 nthmp warning coordination subcommittee meeting

  • Evacuation Planning Playbooks

  • Example of use ( FASTER approach)

  • Example for March 11, 2011 event at Crescent City:

  • FA + S + T + E + R = Height

  • 2.5m + 0m + (-1m) + 0.75m + 0.5m = 2.75m

  • 3m elevation below purple line below

    • Example: Formula for determining playbook evacuation line to use ( FA-S-T-E-R ):

  • FA: Forecasted Amplitudefrom Warning Center

  • +

  • S: Storm surge or existing ocean conditions

  • +

  • T: Maximum tidal height (first 5 hours of tsunami)

  • +

  • E: Forecast error potential (30%; analysis of 2010-11 events)

  • +

  • R: Site amplified run-up potential (from previous modeling)

  • _________________________________

      • Create consistent, useful products for EMs

      • Develop guidance for application

    • Coordinate with CA Coastal Conservancy and NOAA CSC on mutual interests (tsunami and sea-level rise; tide gauges)

    • Plan: maps/guidance completed summer-fall/2013

    • Feedback/Questions for NTHMP WCS:

      • Should national guidance be developed on creation and implementation of playbooks?

      • Specific feedback on FASTER approach?


    January 2013 nthmp warning coordination subcommittee meeting

    Tsunami Observation Team Project

    • Developing tsunami observation teams

    Agenda1

    Agenda

    • Local statements in WR

      • SPS (transition to TLS)

    • Local initial “product” for NWR

      • NWR Broadcast

      • EAS activation


    Local statements

    Local Statements

    • WR currently uses SPS for local statements

      • Subset of official information (from WC/ATWC bulletins)

      • Emphasis on local information and impacts:

        • Headline

        • EQ info

        • Arrival Times

        • Forecast heights (when available)

        • Impacts (expected / actual)


    Local statement automation

    Local Statement Automation

    • Currently…heavy emphasis on manual generation/editing of local statements (SPS)

      • Time-intensive

      • Leads to inconsistencies in format/content (despite WR Supp guidance)

    • Developing GUI and formatter for faster generation of local statements

      • Will also help standardize format/content

    • Use of SPS product header will continue for time-being

    • Hope to begin testing/using new GUI and formatter this year

    • Goal: Transition to “TLS” header (Tsunami Local Statement) (time frame TBD)

      • Headers approved for WFOs

      • Plan to test with 1-3 WR coastal WFOs initially

      • TLS format/content same as SPS – only header to change

      • Use of TLS will again free up SPS for other uses during tsunami events

    Recommendations for part 1 of 3

    Recommendations for (Part 1 of 3):

    • reformatting of existing material, addition of new material, standardization of products within and across warning centers, and shorter durations of time until the next updates.

    • addition of new material will increase length of new products and

    • shorter time durations between updates will increase the number of messages disseminated and received by end-users. However,


    Recommendations for part 1 of 31

    Recommendations for (Part 1 of 3):

    • additional length & additional number of messages will not likely be a problem for end-users of the products (Emergency Managers, Media and General Public), because:

      • media & public will want additional detail & shorter updates.

      • In absence of new & frequently updated information they will generally increase information seeking;

      • emergency managers need to know what information is provided to the media & to the public; and

      • emergency managers can avoid redundancy & information over-load by screening the UPDATES section which clarifies changes from previous messages


    Recommendations for part 1 of 32

    Recommendations for (Part 1 of 3):

    • Revised prototype files provide guidance

    • Gregg could work with WCATWC/PTWC to revise
