Earthquake scenarios are deterministic analysis that consider a single seismic event. It is possible to generate ground motion fields, damage distribution and individual asset and portfolio loss statistics. These results are important for emergency management planning and for raising societal awareness of risk.
This module covers the basic concepts for seismic scenario risk assessment. Modelling alternatives in OpenQuake are presented for earthquake ruptures, exposure and vulnerability models. The module for scenarios is divided in two sessions:
PART 1: Ground motion fields
PART 2: Damage and losses
Learn how to prepare the required input files for the OpenQuake-engine, run an example, and visualise the results.
Prerequisite: Module I
Ground motion fields
MODULE II - PART 1
This session presents the generation of ground motion fields due to deterministic seismic events.
Learn the basic concepts to model a fault rupture in OpenQuake, how to prepare the required input files, run various examples, and compare results based on the modelling assumptions.
damage and losses
MODULE II - PART 2
This session starts from the ground motion fields generated in Part 1 to estimate damage and losses for a given earthquake scenario.
Learn basic concepts for risk assessment, such us exposure and vulnerability models, prepare the required input files for OpenQuake, run an example and visualise damage and loss maps.
Exposure models, vulnerability models, damage and loss statistics and maps.
