To do this it simulates hundreds of thousands of possible tsunami scenarios from key earthquake sources in the Pacific and Indian Oceans, and models the frequency with which these occur. {"type": "Polygon", "coordinates": [[[112.0, -44.0], [154.0, -44.0], [154.0, -9.0], [112.0, -9.0], [112.0, -44.0]]]} 112.0 154.0 -44.0 -9.0 Published_External Tsunami hazard assessment annual exceedance earthquake sources hazard deaggregation hazard modelling tsunami scenario uncertainty quantification Link to website documentDigital Link to website HTML 2018 Australian Probabilistic Tsunami Hazard Assessment Results documentDigital 2018 Australian Probabilistic Tsunami Hazard Assessment Results HTML The 2018 Australian Probabilistic Tsunami Hazard Assessment documentDigital The 2018 Australian Probabilistic Tsunami Hazard Assessment HTML PTHA18 source-code repository and data access scripts documentDigital PTHA18 source-code repository and data access scripts HTML
