description: RiskPulse provides seismic activity data by querying the USGS FDSN event catalog for earthquakes near a given location or globally. It returns per-event details (magnitude, depth, PAGER alert level) and a computed risk summary (low/moderate/high) over a configurable lookback window of up to 365 days.

# riskpulse.theaslangroupllc.com

RiskPulse is a single-purpose seismic data host operated by The Aslan Group LLC. It serves agents that need to assess earthquake risk for a specific geographic coordinate or globally, returning structured event data and a derived risk level. It wraps the USGS FDSN catalog with a simplified query interface and adds a computed risk classification on top of raw event data.

## When to use this host

Use this host when an agent needs recent earthquake activity data for a specific lat/lon coordinate or a global overview, including event counts, magnitudes, depths, PAGER alert levels, and a derived risk classification. The lookback window is configurable up to 365 days and returns at most 100 events per call. Do not use this host for real-time streaming seismic alerts, continuous monitoring, or historical research spanning multiple years — those use cases require a dedicated seismic monitoring service or direct USGS API access with broader query parameters. This host is not suitable for non-seismic natural hazard data (e.g., hurricanes, floods, wildfires); use a dedicated hazard-specific data provider for those.

## Capabilities

### Seismic Risk Assessment

Queries the USGS FDSN event catalog for recent earthquake activity near a location or globally, returning individual event details and a computed risk level summary.

- **`fetch-usgs-earthquake-activity`** — Queries the USGS FDSN event catalog for recent earthquake activity near a lat/lon or globally, returning per-event details and a computed seismic risk summary.

### `fetch-usgs-earthquake-activity`

**RiskPulse Quake Check** — Queries the USGS FDSN event catalog for recent earthquake activity near a lat/lon or globally, returning per-event details and a computed seismic risk summary.

*Use when:* Use when an agent needs recent seismic activity data for a specific location or globally, including event counts, magnitudes, depth, PAGER alert levels, and a computed risk level (low/moderate/high) over a configurable lookback window.

*Not for:* Do not use for real-time streaming seismic alerts or historical earthquake research spanning years; this endpoint is limited to a 365-day lookback and returns at most 100 events per call.

**Inputs:**

- `lat` (number) — Latitude of the point of interest. Omit both lat and lon to query the global M5+ feed.
- `lon` (number) — Longitude of the point of interest. Omit both lat and lon to query the global M5+ feed.
- `radius_km` (number) — Search radius around the point in km. Default 500, max 5000.
- `min_magnitude` (number) — Minimum magnitude filter. Default 4.0 when a point is given, 5.0 for the global feed.
- `days` (integer) — Lookback window in days. Default 30, max 365.
- `limit` (integer) — Maximum number of events returned. Default 20, max 100.

**Returns:** Returns a query echo, a summary object with event_count, max_magnitude, avg_magnitude, and risk_level, plus an events array of up to 100 USGS earthquake records each with magnitude, place, depth, PAGER alert, significance, and URL.

**Example:** `GET https://riskpulse.theaslangroupllc.com/api/risk/quake-check?lat=35.68&lon=139.69&radius_km=500&min_magnitude=4.5&days=30&limit=20`
