Description

Transforms earthquake occurrence times following the Ogata (1988) method based on the integration of the induced seismicity model of model_rate.val(), to then be used as input in stat.KS_uniform().

Usage

## S3 method for class 'transform'
t(data, theta)

Arguments

data

a list containing all the necessary point data:

  • seism an earthquake catalogue data frame of parameters t (time in days) and m (magnitude)

  • inj matching injection profile data frame of parameters t (time in days), dV (flow rate in cubic metre/day) and V (cumulative injected volume in cubic metres)

  • m0 the minimum magnitude cutoff of the earthquake catalogue

  • ts shut-in time (in days)

theta

the list of fitted model parameters:

  • a_fb the underground feedback activation

  • tau the mean relaxation time

  • b the slope of the Gutenberg-Richter law

Details

See examples of induced seismicity applications in Mignan et al. (2017, 2019) and Broccardo et al. (2017).

Value

the transformed time vector
