"Inspired and based on the [USGS Earthquakes](https://github.com/mapbox/mapboxgl-jupyter/blob/master/examples/usgs-earthquakes.ipynb) example from the [Mapbox GL Jupyter library](https://github.com/mapbox/mapboxgl-jupyter), this notebook visualizes data on accidents by snow avalanches causing at least one fatality in Switzerland. See [Why the Swiss are experts at predicting avalanches](https://www.swissinfo.ch/eng/unesco-cultural-heritage_why-the-swiss-are-experts-at-predicting-avalanches/43755460) (swissinfo) for some interesting background on the subject.\n",
