Hazard
Helpers for querying Hazard Realizations and related models.
Provides efficient queries for the models: HazardAggregation, OpenquakeRealization & ToshiOpenquakeMeta.
Functions:
- get_hazard_metadata_v3() - returns iterator of matching ToshiOpenquakeMeta objects.
- get_rlz_curves_v3() - returns iterator of matching OpenquakeRealization objects.
- get_hazard_curves() - returns iterator of HazardAggregation objects.
get_hazard_curves(locs, vs30s, hazard_model_ids, imts, aggs=None)
¶
Query the HazardAggregation table for matching hazard curves.
Examples:
>>> get_hazard_curves(
locs=['-46.430~168.360'],
vs30s=[250, 350, 500],
hazard_model_ids=['NSHM_V1.0.4'],
imts=['PGA', 'SA(0.5)']
)
>>> <generator object get_hazard_curves at 0x7f115d67be60>
Parameters:
