Earthquake Modeling¶

The earthquake model can be imported using the following command. The earthquake model has been build using the following literature resources

Jeddi et al. (2022) Baghmisheh & Mahsuli (2021) FEMA (2020) Farahani et al. (2020) Kongar et al. (2017) Kongar et al. (2014) Cirone (2013) Atkinson & Wald (2007) Rajabzadeh & Kalantar (2022) Mo et al. (2017)

from IPython.display import display, HTML
import plotly.graph_objects as go
import plotly.io as pio

pio.renderers.default = "plotly_mimetype"

from erad.models.hazard import EarthQuakeModel

/opt/homebrew/Caskroom/miniconda/base/envs/erad/lib/python3.12/site-packages/kaleido/__init__.py:14: UserWarning:



Warning: You have Plotly version 6.0.1, which is not compatible with this version of Kaleido (1.0.0).

This means that static image generation (e.g. `fig.write_image()`) will not work.

Please upgrade Plotly to version 6.1.1 or greater, or downgrade Kaleido to version 0.2.1.

An instance of EarthQuakeModel requires four pieces of information,

timestamp: The timestamp the earthquake happened
origin: Epicenter of the earthquake in lat / long format
depth: Depth of the earthquake, beneth the surface of the earth
magnitude: Magnitude of the earthquake

from datetime import datetime

from gdm.quantities import Distance
from shapely.geometry import Point

earthquake = EarthQuakeModel(
    name="same name",
    timestamp=datetime.now(),
    origin=Point(-120, 36),
    depth=Distance(30, "km"),
    magnitude=6.2,
)
earthquake.pprint()

An example of the EarthQuakeModel can be built using the example() methods for testing purposes.

earthquake = EarthQuakeModel.example()
earthquake.pprint()

Building from historical events¶

Erad allows users to build earthquake models from historic earthquake events as well. The from_earthquake_code class method can be used to build earthquake models representing historic events.

earthquake = EarthQuakeModel.from_earthquake_code("ISCGEM851547")
earthquake.pprint()

Plotting Earthquake Model¶

fig = go.Figure()
earthquake.plot(figure=fig)
fig.show()
