## Pricing

from $0.50 / 1,000 earthquakes

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## USGS Earthquake Search: Worldwide Quakes by Area & Magnitude

Search the official **U.S. Geological Survey (USGS) earthquake catalog** for earthquakes anywhere in the world. You can filter by date range, **magnitude**, **depth**, a **radius around any point**, a **bounding box**, the **PAGER impact alert level**, the **tsunami flag**, and whether people **reported feeling it**. Each row includes the time (UTC), magnitude and type, place, latitude, longitude, depth, felt reports, maximum intensity (CDI/MMI), alert level, review status and a link to the USGS event page. No login, no API key.

### Who is it for?

- **Insurers, reinsurers and risk analysts** building event lists for exposure and claims work.
- **Logistics, supply chain and travel teams** that monitor disruption near sites and routes.
- **Researchers, students and journalists** analyzing seismic activity.
- **Developers** feeding alerts, maps and dashboards on a schedule.

### How to use it

1. Set **Last N days**, or a start and end date.
2. Set a **minimum magnitude** (the default is 2.5).
3. Optionally search a **circle** (center latitude, longitude and radius in km) or a **bounding box** (south,west,north,east).
4. Optionally filter by **alert level**, **tsunami flag** or **felt reports**, and sort by time or magnitude.
5. Click **Start** and export to CSV, Excel or JSON, or schedule it.

### Input example

```json
{"lastDays": 30, "minMagnitude": 4.5, "latitude": 35.68, "longitude": 139.69, "radiusKm": 500, "sortBy": "magnitude"}
```

### Output example

```json
{"id": "us7000abcd", "time": "2026-10-25T14:03:11Z", "magnitude": 5.12, "magnitudeType": "mww", "place": "45 km E of Hachinohe, Japan", "latitude": 40.51, "longitude": 142.03, "depthKm": 35.0, "feltReports": 112, "alertLevel": "green", "tsunamiFlag": false, "url": "https://earthquake.usgs.gov/earthquakes/eventpage/us7000abcd"}
```

### How much does it cost?

Pay-per-event: a small fee **per earthquake** returned, plus a tiny per-run start fee. There is no subscription and no separate platform usage cost. For example, 1,000 earthquakes cost about $0.50. Searches with no matches and error rows are **not charged**. Set **Max results** or **Maximum cost per run** to cap your spending.

### Use it through the API, integrations or AI agents

Run it from the Apify API, on a schedule, or connect it to Make, Zapier, n8n or Google Sheets. AI agents can find and call it through the Apify MCP server. Output is clean JSON with the same fields on every run.

### FAQ

**Is it legal?** Yes. USGS earthquake data is U.S. government public domain data, offered through the public ComCat API. No personal data is involved.

**How fresh is the data?** Events usually appear within minutes. Magnitudes and locations can be revised as USGS reviews them, and the `status` field shows `automatic` or `reviewed`.

**What is the PAGER alert?** It is the USGS estimate of shaking impact (green, yellow, orange or red). Only larger events get one.

**Why do I see fewer results than expected?** Check your minimum magnitude. Small quakes (below 2.5) are only reported completely in some regions, mostly the United States.

**Can I use it for warnings?** No. Use official national warning services for safety decisions.

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,pankajbhatia/usgs-earthquake-search"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
