## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Earthquake Alert — Recent Seismic Activity by Region

Search recent earthquakes worldwide by minimum magnitude, a region (radius
around a latitude/longitude), or USGS PAGER estimated-impact level. Get back
magnitude, location, depth, tsunami flag, and a link to the full USGS event
page — most recent first.

Built for catastrophe/insurance risk teams, logistics and supply-chain
monitoring, and disaster-response coordination watching a specific region.

### Input

```json
{
  "latitude": 34.0522,
  "longitude": -118.2437,
  "radiusKm": 300,
  "minMagnitude": 4.5,
  "alertLevel": "all",
  "daysBack": 7,
  "maxResults": 25
}
```

| Field | Type | Description |
|---|---|---|
| `latitude` / `longitude` | number | Center point for a regional search. Leave both blank for a worldwide search. |
| `radiusKm` | number | Search radius around the center point, in km. Only used with `latitude`/`longitude`. Default `300`. |
| `minMagnitude` | number | Only return earthquakes at or above this magnitude. Default `4.5`. |
| `alertLevel` | string | USGS PAGER estimated impact: `all`, `green`, `yellow`, `orange`, or `red`. Most earthquakes have no alert level — leave `all` unless specifically hunting for significant events. |
| `daysBack` | number | How many days back from today to search. Default `7`, max `365`. |
| `maxResults` | number | Max earthquakes to return, most recent first. Default `25`, max `100`. |

### Output

One record per earthquake:

```json
{
  "eventId": "us6000tjqj",
  "magnitude": 5.1,
  "magType": "mb",
  "place": "232 km SSW of Pagar Alam, Indonesia",
  "time": "2026-08-10T17:08:06.809Z",
  "alertLevel": null,
  "tsunami": false,
  "felt": null,
  "cdi": null,
  "significance": 400,
  "status": "reviewed",
  "depthKm": 21.72,
  "latitude": -5.9347,
  "longitude": 102.3607,
  "url": "https://earthquake.usgs.gov/earthquakes/eventpage/us6000tjqj"
}
```

### How it works

Direct calls to the official [USGS Earthquake Hazards Program](https://earthquake.usgs.gov/)
FDSN event API — the same data source behind USGS's own earthquake maps. No
API key, no proxy, no login, no scraping.

### Pricing note

Billed per **search**, not per earthquake returned — one charge whether the
search returns 1 event or 100.

# Actor input Schema

## `latitude` (type: `number`):

Center point latitude for a regional search. Leave blank (with longitude) for a worldwide search.

## `longitude` (type: `number`):

Center point longitude for a regional search. Leave blank (with latitude) for a worldwide search.

## `radiusKm` (type: `integer`):

Search radius around the latitude/longitude, in kilometers. Only used if latitude and longitude are both set.

## `minMagnitude` (type: `number`):

Only return earthquakes at or above this magnitude.

## `alertLevel` (type: `string`):

USGS PAGER estimated impact level: green (minimal), yellow, orange, or red (severe). Leave as "all" to skip this filter — most earthquakes have no alert level at all.

## `daysBack` (type: `integer`):

How many days back from today to search.

## `maxResults` (type: `integer`):

Maximum number of earthquakes to return, most recent first.

## Actor input object example

```json
{
  "radiusKm": 300,
  "minMagnitude": 4.5,
  "alertLevel": "all",
  "daysBack": 7,
  "maxResults": 25
}
```

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("m_ctim/earthquake-alert").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## CLI example

```bash
echo '{}' |
apify call m_ctim/earthquake-alert --silent --output-dataset

```

## MCP server setup

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

```

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).
