gemgis.visualization.create_meshes_hypocenters(gdf: geopandas.geodataframe.GeoDataFrame, magnitude: str = 'Magnitude', magnitude_factor: int = 200, year: str = 'Year') → pyvista.core.composite.MultiBlock#

Plotting earthquake hypocenters with PyVista

Parameters

  • gdf (gpd.geodataframe.GeoDataFrame) – GeoDataFrame containing the earthquake hypocenter data

  • magnitude (str) – Name for the column containing the magnitude value, e.g. magnitude='Magnitude', default is 'Magnitude'

  • magnitude_factor (int) – Scaling factor for the magnitude values defining the size of the spheres, e.g. magnitude_factor=200, default is 200

  • year (str) – Name for the column containing the year of each earthquake event, e.g. year='Year', default to 'Year'

Returns

spheres – PyVista MultiBlock object containing the hypocenters stored as spheres

Return type

pv.core.composite.MultiBlock

New in version 1.0.x.
