USGS Volcano Message API
Volcano messages are quick and short peices of information we display on web pages during eruptions.
At the time of this writing, only Kilauea, vnum = 332010, has messages.
The vnum parameter is the value assigned by the Smithsonian
Institution's Global Volcanism Program and can be found here:
https://volcanoes.usgs.gov/vsc/api/volcanoApi/volcanoesUS.
