*Social science research is a part of all five priorities (e.g. post alert messaging, WEA messaging, protective actions, logo style guide, WEA test analysis, etc. All social sciencce projects address critical needs for ShakeAlert Operations. + Special consideration is given to address the needs of diverse communities: e.g. limited literacy, limited English proficiency, disabilities, access, and functional needs. ShakeAlert is committed to serving all end users. Goals

DEVELOP UNDERSTANDING OF WHERE ESTABLISH A LONG POPULATIONS ARE CURRENTLY IN TERMS OF RISK PERCEPTION, PROTECTIVE ACTION TERM MONITORING KNOWLEDGE, AND BASIC PREPAREDNESS AND EVALUATION PLAN ACROSS WASHINGTON, OREGON, AND CALIFORNIA. FOR SHAKEALERT PROJECTS IN 8 ACTIVE PROJECTS 2019/2020 9 UNIVERSITIES/RESEARCH AGENCIES FROM 5 STATES AND TWO COUNTRIES About the alerting platforms:

• Only one alerting platform publicly available at the time: the ShakeAlertLA app developed by the City of Los Angeles. (There are now three). • Alerting thresholds were set for M5.0+ and MMI 4+. • Due to public response, thresholds for apps were lowered to M4.5+ and MMI 3+. • Caltech developed UserDisplay was available to select ShakeAlert users only but filmed live during a media conference during the Ridgecrest sequence. About the ALERTS WERE NOT WHILE THRESHOLDS THE APP DID NOT Ridgecrest SENT OUT VIA THE MIGHT HAVE BEEN PROVIDE SHAKEALERTLA APP MET FOR THE M7.1, INFORMATION FOR EITHER THE THE SHAKEALERT ABOUT THE M6.4 AND M7.1 SYSTEM ESTIMATED EARTHQUAKES ON and EARTHQUAKES DUE THE EARTHQUAKE THEIR MAP OR TO NEITHER AT M6.3 RATHER RECENT ShakeAlertLA MEETING THE THAN AN M7.1. EARTHQUAKE LISTS ESTIMATED SHAKING THRESHOLD.. DATA COLLECTION AND ANALYSIS

Media analysis: 69 stories analyzed from July – November 2019 about the Ridgecrest earthquakes. Stories collected via News; searches began 36 hours post first event and continued monthly after the first searches until November 2019. All stories were coded in NVIVO, using thematic analysis.

600,000+ tweets was the data set as collected by Pushshift by Jason Baumgartner. Collection began within 24 hours of the M6.4 quake, in time to collect real time data from the M7.1 quake.

Social Media analysis: 2,100 analyzed and 1600+ coded from the date of the first earthquake until 10 days later. Search terms were: #shakealert and #shakealertla. All tweets were coded in NVIVO, using thematic analysis. TYPES OF MEDIA ANALYZED

• PRINT (NEWSPAPERS) • LOCAL/REGIONAL • TELEVISION • NATIONAL • RADIO • INTERNATIONAL (WIRES) • ELECTRONIC MEDIA (ONLINE ONLY) • MAGAZINE • BLOGS RIDGECREST EARTHQUAKES MEDIA Anchorage Earthquake Sequence BOMBAY BEACH SWARM 2016 COMPARISON OF MEDIA ANALYZED BY THE THREE SEQUENCES PRELIMINARY FINDINGS – MEDIA ANALYSIS

Third most coded theme 25 articles out of the Top three themes in media stories; the were: ShakeAlertLA (19 69 analyzed mentioned other first was articles), Threshold (19 ShakeAlert. aftershocks (52 stories), other than the original articles), and Failure earthquakes (10). PRELIMINARY FAILURE (446 POOR MEDIA STORIES ANALYSIS – TWEETS OUT OF PERFORMANCE E.G. WERE THE ONLY THE 1668 TWEETS). BATTERY DRAIN, LINKS OR SOCIAL PEOPLE WERE LOCATION ISSUES COMMENTS DISAPPOINTED IN (NOT JUST FAILURE RETWEETED AFTER MEDIA THE APP (RATHER TO ALERT) WAS 72 HOURS POST THE THAN MENTIONING ALSO AN ISSUE, LAST LARGE THE FAILURE ONLY).

ALONE WAS NOT THE ONLY ISSUE (446 TWEETS SEARCHING FOR USGS WEBSITE ISSUES AUTHORATIVE CAUSED FURTHER INFORMATION FOR ON FAILURE) FRUSTRATIONS. CONFIRMATION AND FINDING NONE. CONFUSION POINTS

• THRESHOLD (MMI/MAG): PEOPLE WERE MOST CONFUSED ABOUT MMI/MAGNITUDE DIFFERENCES (256 tweets). • WEA TESTS: WEA TESTS CONDUCTED IN SAN DIEGO 10 DAYS PRIOR (4 tweets). • SHAKEALERT (USGS)/SHAKEALERTLA (CITY OF LOS ANGELES)/USERDISPLAY (92 tweets). • MISINFORMATION ON E.G. EARTHQUAKE PREDICTION (21 tweets). Questions and comments about ShakeAlert • 57 TWEETS DEDICATED TO ASKING FOR IT IN THEIR COUNTIES (SAN BERNARDINO, KERN, SAN DIEGO), DESPITE FAILURE NARRATIVES. • 11 TWEETS CLAIMED TO UNINSTALL APP AND 5 EXPLORED LOSS OF TRUST. • 4 TWEETS TALKED ABOUT TESTING THE SYSTEM. • 85 TWEETS ON SUGGESTIONS FOR IMPROVEMENTS OF THE APP (MOSTLY AROUND CHOOSING THEIR OWN ALERTING THRESHOLDS).

SHAKEALERTLA HAS A LOWERED THRESHOLD. CONCLUSIONS

• THE COMMUNICATION OF FAILURE WAS NOT STRAIGHTFORWARD. • MEDIA STORIES FOCUSED ON FAILURE BUT ALSO ON THE THRESHOLDS. • RATHER, THE FAILURE WAS PERCEIVED AS A LACK OF INFORMATION IN OUR COMMUNICATION ECOSYSTEM. DIVERSITY OF COMMUNICATION CHANNELS COULD IMPROVE THIS OUTCOME FOR FUTURE EARTHQUAKES. • WHILE LOWERING THE THRESHOLDS WAS POPULAR, THERE WERE DISENTING OPINIONS BY INFLUENCERS ON TWITTER. • THE INDIVIDUAL INFLUENCERS WERE NOT NECESSARILY THE MOST RETWEETED ACCOUNTS. • MEDIA CONTINUES TO HAVE A CRITICAL ROLE TO THE COMMUNICATION OF SHAKEALERT, SHIFTING THEIR PLATFROMS FROM BROADCAST TO INCLUDE SOCIAL MEDIA FOR DISSEMINATION QUESTIONS? [email protected] OR AND STORY GATHERING. AFTER THE FIRST FIVE DAYS, ONLY MEDIA STORIES WERE RETWEETED. @DISASTROUSCOMMS
