Each entry filters new earthquakes by min magnitude, place (substring) and/or region. An entry is an object { "minMag": , "place": , "region": }; place is matched case-insensitively against the USGS place description, region is either a numeric Flinn-Engdahl code (sent server-side) or a place substring. Leave empty to monitor every earthquake worldwide at the top-level min magnitude. One checkpoint is kept per entry so repeat runs emit only new events.
How far back to look for earthquakes on the first run; repeat runs only emit events newer than the last checked state.
Default minimum magnitude applied to watchlist entries that do not set their own minMag.
