Modelling Geophysical Hazard
Infinite Observations offers models to better prepare residents, businesses and governments for the human as well as the economic consequences of catastrophic earthquakes. We leverage local, regional as well as worldwide expertise in earthquake modelling. Earthquake modelling is very complex and it is inadequate to rely on historical data to forecast where future earthquakes will occur and the scale of devastation that they inflicted. Infinite Observations makes use of a harmonized set of Ground Motion Prediction Equations (GMPEs) that can be used globally as well as regionally. GMPEs or “attenuation” relationships are predominantly used in regions considered tectonically stable.
These equations provide scientists with a method of predicting the level of ground motion, the related uncertainty at any given geographic location or site, based on the magnitude, distance, soil conditions, fault mechanism, etc. To be able to estimate human as well as economic losses we must be able to represent the seismic hazard and risk in a particular region. This is a description of seismic hazard, physical infrastructure, population, census and household data, building occupancy (day, night and transient hours), vulnerability and fragility curves according to the probability of loss ratio for predominant building topologies.

Seismic Vulnerability, Exposure & Risk Modelling
A Global Data Driven Seismic Model
Infinite Observations makes use of a Global Seismic Hazard Model that depicts the geographic distribution of the Peak Ground Acceleration (PGA) and a range of Spectral Acceleration Periods (SAP) with a 10% probability of being exceeded in 50 years, computed for reference rock conditions. The earthquake hazard map, based on a database of hazard models, is employed using a collection and combination of national and regional probabilistic seismic hazard models developed by various agencies, institutions and projects worldwide. Our Global Seismic Hazard Model can be updated with new models that can be incorporated into the platform and the underlying database. The earthquake engine analyses the seismic hazard and risk ratios fallowed by a smoothing technique that is applied to homogenise the hazard ratios throughout the model. The model can also be implemented to determine stochastic event datasets. Extensive checks, tests, and calibrations are performed on the model to ensure compatibility between the results of our platform and those of other vendors of earthquake hazard modelling software.
Quantifying Seismic Hazard Losses
With the implementation of our Global Seismic Hazard Model Infinite Observations is able to analyse the hazard due to ground motion for any given return period in terms of peak ground acceleration and a range of spectral acceleration periods. Seismic hazard is impacted by shaking of the ground and is exacerbated by the high vulnerability of its built environment. These aspects are captured by our Global Seismic Hazard Model risk model, which contains exposed assets and vulnerability functions. Average Annual Losses estimates (AAL), loss ratios and loss exceedance curves at various spatial resolutions are derived from a stochastic event catalogue that is included in an exposure database that contains population, residential, industrial, and commercial building data that are grouped into different structural classes and structural characteristics. Nonlinear dynamic analysis of numerical models of the structures are used to derive vulnerability functions for each structural class and validated against historical events.
