How to download an Earthquake Catalog

from obspy.clients.fdsn import Client
from obspy import UTCDateTime

# Initialize the AusPass FDSN client
client = Client("AUSPASS")

# Define the time range for the earthquake catalog
start_time = UTCDateTime("2021-08-01")
end_time = UTCDateTime("2022-01-01") # End of year

# Define the geographic region (latitude and longitude for Woodspoint, Victoria, Australia)
latitude = -37.47
longitude = 146.10
max_radius = 5 # in degrees

# Download the earthquake catalog
catalog = client.get_events(starttime=start_time, endtime=end_time,
minmagnitude=2, latitude=latitude, longitude=longitude,
maxradius=max_radius)

# Save the catalog to a file (e.g., QuakeML format)
catalog.write("Woodspoint_earthquakes.xml", format="QUAKEML")
