EarthMaster Explorer is a live seismic waveform viewer and global hazard-monitoring dashboard, built for real-time earthquake, tsunami, solar activity, and volcanic monitoring. Live Waveforms Browse and stream real seismic station data from the global EarthScope/IRIS network — hundreds of stations worldwide, viewable via HTTP polling or real-time SeedLink streaming. When a significant earthquake occurs, the app automatically adds the nearest working station to its epicenter. Global Hazard Monitoring Tsunami warnings and earthquake alerts Solar flare activity (X-ray flux monitoring) Cascadia tremor tracking Volcano alert levels across the lower-48 US volcanoes Near-Earth asteroid close-approach tracking Current moon phase, calculated locally with an accurate astronomical model A composite Seismic Activity Index summarizing global activity at a glance Fully Customizable Adjustable alert thresholds for every monitor, station favorites, custom waveform and app color themes, and an optional custom weather location. Built entirely on public, freely available data from official scientific agencies — USGS, EMSC, EarthScope/IRIS, NOAA, PNSN, NASA/JPL, and Open-Meteo.
