- Fault Source Models Show Slip Rates Measured across the Width of the Entire Fault Zone Best Represent the Observed Seismicity of the Pallatanga–Puna Fault, Ecuador | GEM Foundation
Publications Fault Source Models Show Slip Rates Measured across the Width of the Entire Fault Zone Best Represent the Observed Seismicity of the Pallatanga–Puna Fault, Ecuador Share Facebook LinkedIn Download 2024 | Peer-reviewed We explore how variation of slip rates in fault source models affect computed earthquake rates of the Pallatanga–Puna fault system in Ecuador. Determining which slip rates best represent fault‐zone seismicity is vital for use in probabilistic seismic hazard assessment (PSHA). However, given the variable spatial and temporal scales slip rates are measured over, significantly different rates can be observed along the same fault. The Pallatanga–Puna fault in southern Ecuador exemplifies a fault where different slip rates have been measured using methods spanning different spatial and temporal scales, and in which historical data and paleoseismic studies provide a record of large earthquakes over a relatively long time span. We use fault source models to calculate earthquake rates using different slip rates and geometries for the Pallatanga–Puna fault, and compare the computed magnitude–frequency distributions (MFDs) to earthquake catalog MFDs from the fault zone. We show that slip rates measured across the entire width of the fault zone, either based on geodesy or long‐term geomorphic offsets, produce computed MFDs that compare more favorably with the catalog data. Moreover, we show that the computed MFDs fit the earthquake catalog data best when they follow a hybrid‐characteristic MFD shape. These results support hypotheses that slip rates derived from a single fault strand of a fault system do not represent seismicity produced by the entire fault zone.

- The GEM Global Active Faults Database | GEM Foundation
Publications The GEM Global Active Faults Database Share Facebook LinkedIn Download 2020 | Peer-reviewed The GEM Global Active Faults Database (GAF-DB) is the first public, comprehensive database of active faults with worldwide coverage. The GAF-DB is a compilation of many regional datasets. The GAF-DB contains ∼13,500 faults, each with associated attributes that describe the geometry, kinematics, slip rate, references, and other characteristics, as the information is available. Spatial completeness is high, and about 77% of the faults have slip rate information. The GAF-DB is built from its constituent datasets algorithmically and is designed to fluidly incorporate changes to or addition of any of the underlying datasets. This process reflects a philosophy of easily incorporating a change to avoid obsolescence and to quickly provide the most up-to-date information possible to the users.

- Development of a uniform exposure model for the African continent for use in disaster risk assessment | GEM Foundation
Publications Development of a uniform exposure model for the African continent for use in disaster risk assessment Share Facebook LinkedIn Download 2022 | Peer-reviewed Several destructive natural hazards have occurred throughout Africa over the past century, yet few comprehensive exposure models exist for the continent. The high population growth and rapid pace of urbanization within many African countries entail a significant potential for increased economic and human losses, particularly where substantial urban growth encroaches upon hazard-prone regions with inadequate land management and building design regulations. This study introduces a new exposure model for all African countries using national and global datasets with a uniform approach across the continent, developed for a baseline year (2020) and six future years (2025, 2030, 2035, 2040, 2045, and 2050). The exposure model was originally derived with subnational statistics, and then further spatially disaggregated using Earth Observation (EO) data. This refined spatial resolution allows the model to reflect a realistic population distribution within each country and thereby better characterizes the potential risk to natural hazards and allows identification of disaster risk hotspots. The results indicate the current concentrations of building stock in Africa, in addition to regions where the urban building stock is expected to nearly triple (such as in Central and East Africa) or at least double (such as in West and South Africa).

- Earthquake scenarios for building portfolios using artificial neural networks: Part I – Ground motion modelling | GEM Foundation
Publications Earthquake scenarios for building portfolios using artificial neural networks: Part I – Ground motion modelling Share Facebook LinkedIn Download 2022 | Peer-reviewed The calculation of the spatial distribution of ground motion is one of the most important steps in earthquake scenarios. The advancements in machine learning algorithms and the release of new ground motion data can enable improvements in the reliability and accuracy of this component. We developed an artificial neural network (ANN) ground motion model using a compiled database from two subsets with measured Vs30 from the Pan-European strong motion database and the NGA-West2 database. The ANN model employs five input parameters: moment magnitude (Mw), hypocentral depth, Joyner–Boore distance (Rjb), shear wave velocity in the top 30 m (Vs30), and faulting type. The outputs of the ANN are the RotD50 horizontal components of common intensity measures used in seismic risk assessment: PGA, PGD, PGV, Arias Intensity, and 5% damped spectral acceleration at 27 periods from 0.01 to 4.0 s. A mixed-effects modelling approach was followed to train the ANN and partition the ground motion variability into between-event and between-site terms. The input parameter scaling relationships were studied and demonstrated physically sound trends of the ground motion with respect to Mw scaling, distance attenuation, and site amplification. The predicted median response spectra for several combinations of Mw and Rjb were compared to common ground motion models for Europe, and the results are discussed. The developed ANN is used in a companion study to calculate the hazard footprints for several historical earthquakes in the Balkan region.
