Abstract
On 14 July 2019 a magnitude 6.6 (Mw) earthquake occurred in the Indian Ocean, 210 km WSW of Broome. This event, equal to the largest recorded in Australia, has provided an important learning opportunity. When the earthquake struck, Geoscience Australia issued an earthquake notification. The event was deemed ‘potentially tsunamigenic’, however, after further analysis, the Joint Australian Tsunami Warning Centre issued a national No Threat tsunami bulletin. No deaths or injuries were recorded and reports indicated only minor damage to buildings. Given the low frequency and potentially high impact of earthquakes on Broome, this event was a rare opportunity for the emergency management sector to improve its understanding of this hazard. Using Geoscience Australia’s crowdsourced “Felt Reports”, DFES internal incident management system records, media reports, social media and eyewitness accounts, DFES was able to carry out a detailed post incident analysis. Key opportunities include: Stronger “Drop, Cover and Hold” messaging, and an improved understanding and communication of self-evacuation triggers This poster presents WA Department of Fire and Emergency Services’ (DFES) insights and lessons learned from analysis of GA’s macroseismic information products (felt reports) as part of DFES’ post-event review of the Broome earthquake 14 July 2019. Prepared for the 2019 Australian Earthquake Engineering Society Conference, Newcastle, NSW, November 2019.
