toshi-hazard-store (library)¶

To use toshi-hazard-store in a project you must first

install the library, and
configure it for your requirements (e./g cloud use (say the published NSHM), or local offline use)

Now, you should be able to interact with the data available in the chosen database.

Query the hazard store in python ...¶

from toshi_hazard_store import query
import pandas as pd
import  json

TOSHI_ID = "abcdef"

## get some solution meta data ...
for m in query.get_hazard_metadata(None, vs30_vals=[250, 350]):
    print(m.vs30, m.haz_sol_id, m.locs)

    source_lt = pd.read_json(m.src_lt)
    gsim_lt = pd.read_json(m.gsim_lt)

    rlzs_df = pd.read_json(m.rlz_lt) # realizations meta as pandas datframe.
    rlzs_dict = json.loads(m.rlz_lt) # realizations meta as dict.

    print(rlzs_dict)
    print(rlzs_df)


## get some agreggate curves
for r in query.get_hazard_stats_curves(m.haz_sol_id, ['PGA'], ['WLG', 'QZN', 'CHC', 'DUD'], ['mean']):
    print("stat", r.loc, r.values[0])
    break

## get some realisation curves
for r in query.get_hazard_rlz_curves(m.haz_sol_id, ['PGA'], ['WLG', 'QZN', 'CHC', 'DUD']):
    print("rlz", r.loc, r.rlz, r.values[0] )
    break
