In wltcwpf/RPSHA: This package implements LASSO to conduct earthquake event/ground motion map selection

A function to convert an event to the target magnitude and/or distance hazard distribution

Description

This function takes a target magnitude and/or distance hazard distribution and an events to calculate the hazard of the event at each of the corresponding magnitude/distance/ intensity measure type/intensity measure level or return period.

Usage

Event_to_MR_Hazd(
  MR_Hazd,
  Mag,
  AnnualOccurrenceRate,
  Fault_type,
  region = 1,
  Sitelist,
  distribution = "cdf"
)

Arguments

MR_Hazd	A dataframe with six or seven (if both magnitude and distance hazard distributions are interested) columns: "IM_type", "Deagg_level", "SiteName", "IM_level", "Hazd", "Magnitude"/"R_distance" (or "MagRType" and "MagR"). Note the column names should exactly match these variable names. MR_Hazd can be directly provided by the function of Deagg_to_MR_Hazd.
Mag	The magnitude of the event
AnnualOccurrenceRate	The annual occurrence rate of the event
Fault_type	The fault type of the event: 0 for unspecified fault; 1 for strike-slip fault; 2 for normal fault; 3 for reverse fault
region	The region of the event. Default is 1 for California
Sitelist	A dataframe of sites with four columns: SiteName (should be consistent with the SiteName in MR_Hazd), Vs30, z1, and Rjb. The example info for SiteName, Vs30, and z1 can be found on this webpage: https://raw.githubusercontent.com/wltcwpf/Dataset/main/RPSHA/SiteTable.csv. The example of Rjb can be found on this webpage: https://raw.githubusercontent.com/wltcwpf/Dataset/main/RPSHA/EventSet.csv.
distribution	The distribution representation. "cdf" stands for cumulative hazard and "pdf" stands for discrete bin hazard.

Value

A dataframe with six or seven (if both magnitude and distance hazard distributions are interested) columns is returned, the columns inlcude IM_type, Deagg_level, SiteName, IM_level, Hazd_event, Magnitude/R_distance (or MagRType and MagR)
