List recent earthquakes worldwide from the USGS feed. Filter by minimum magnitude, look-back window in days, and optionally a bounding box or a point+radius (km). Returns magnitude, place, time, depth and coordinates.
Optional center latitude for a radius search.
Optional center longitude for a radius search.
Look back this many days (default 7, max 30).
Maximum number of quakes to return.
Radius in km around lat/lon (requires lat+lon).
Only return quakes at or above this magnitude.

}Get the ground elevation at a latitude/longitude within the US, from the USGS Elevation Point Query Service. Returns elevation in feet and meters.
| Argument | Type | Description |
|---|---|---|
| lat* | number | Latitude in decimal degrees, e.g. 39.5883. US coverage only (USGS). |
| lon* | number | Longitude in decimal degrees, negative in the western hemisphere, e.g. -105.6438. |

}Convert a US street address OR a city/town name into latitude/longitude coordinates, using US Census data. Accepts both '1600 Pennsylvania Ave NW, Washington DC' and 'Chicago, IL' - a place name returns the centroid of the city. Call this first whenever you have a location as text and need coordinates for the weather or elevation tools. US locations only.
| Argument | Type | Description |
|---|---|---|
| address* | string | A US street address ('1600 Pennsylvania Ave NW, Washington DC') or a city or town ('Chicago, IL', 'Springdale, Arkansas') |

| Argument | Type | Description |
|---|---|---|
| area* | string | Two-letter US state code, e.g. PA, TX, CA (full state names such as Pennsylvania are also accepted). |

| Argument | Type | Description |
|---|---|---|
| lat* | number | Latitude in decimal degrees, e.g. 36.1867. US coverage only (National Weather Service). |
| lon* | number | Longitude in decimal degrees, negative in the western hemisphere, e.g. -94.1288. |

}Get a multi-day weather forecast for a US location by latitude/longitude (National Weather Service). Returns named periods (Today, Tonight, ...) with temperature, wind, and a short + detailed forecast. Use geocode first if you only have an address.
| Argument | Type | Description |
|---|---|---|
| lat* | number | Latitude in decimal degrees, e.g. 36.1867. US coverage only (National Weather Service). |
