Question-driven ensembles of flexible ETAS models
Leila Mizrahi, Shyam Nandan, William Savran +2
The development of new earthquake forecasting models is often motivated by one of the following complementary goals: to gain new insights into the governing physics and to produce…
Embracing Data Incompleteness for Better Earthquake Forecasting
Leila Mizrahi, Shyam Nandan, Stefan Wiemer
We propose two methods to calibrate the parameters of the epidemic-type aftershock sequence (ETAS) model based on expectation maximization (EM) while accounting for temporal variat…
The Effect of Declustering on the Size Distribution of Mainshocks
Leila Mizrahi, Shyam Nandan, Stefan Wiemer
Declustering aims to divide earthquake catalogs into independent events (mainshocks), and dependent (clustered) events, and is an integral component of many seismicity studies, inc…
Forecasting the full distribution of earthquake numbers is fair, robust and better
Shyam Nandan, Guy Ouillon, Didier Sornette +1
Forecasting the full distribution of the number of earthquakes is revealed to be inherently superior to forecasting their mean. Forecasting the full distribution of earthquake numb…
Forecasting the rates of future aftershocks of all generations is essential to develop better earthquake forecast models
Shyam Nandan, Guy Ouillon, Didier Sornette +1
Currently, one of the best performing and most popular earthquake forecasting models rely on the working hypothesis that: "locations of past background earthquakes reveal the proba…
Autonomous decision-making against induced seismicity in deep fluid injections
Arnaud Mignan, Marco Broccardo, Stefan Wiemer +1
The rise in the frequency of anthropogenic earthquakes due to deep fluid injections is posing serious economic, societal, and legal challenges to geo-energy and waste-disposal proj…
Objective Estimation of Spatially Variable Parameters of Epidemic Type Aftershock Sequence Model: Application to California
Shyam Nandan, Guy Ouillon, Stefan Wiemer +1
The ETAS model is widely employed to model the spatio-temporal distribution of earthquakes, generally using spatially invariant parameters. We propose an efficient method for the e…
Systematic Assessment of the Static Stress-Triggering Hypothesis using Inter-earthquake Time Statistics
Shyam Nandan, Guy Ouillon, Jochen Woessner +2
A likely source of earthquake clustering is static stress transfer between individual events. Previous attempts to quantify the role of static stress for earthquake triggering gene…
