## 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

## USGS Global Earthquake, Tsunami & Seismic Hazards API

An autonomous, ultra-fast Apify Actor providing real-time access to the **United States Geological Survey (USGS) Global Earthquake and Tsunami Hazard Feeds**.

Filter seismic events by Richter magnitude, GPS circular radius (latitude/longitude/distance), depth, time window, and tsunami alert flags.

***

### 🌋 Features

- **Real-Time Global Coverage**: Pulls authoritative seismic records from the USGS National Earthquake Information Center (NEIC).
- **Radius Search by GPS**: Locate seismic activity within X kilometers of any city, critical infrastructure, data center, or property portfolio.
- **Tsunami Warning Alerts**: Immediate flagging of seismic events that triggered official Pacific / NOAA tsunami warnings.
- **Detailed GeoJSON Metrics**: Modified Mercalli Intensity (MMI), depth in kilometers, PAGER impact significance index, and felt community reports.
- **Zero Overhead**: Direct official government API with sub-second latency (< 200ms) and zero third-party dependencies.

| `minMagnitude` | `Number` | `3.0` | Minimum Richter magnitude (e.g. `2.5`, `4.5`, `6.0`). |
| `maxMagnitude` | `Number` | `null` | Optional upper bound magnitude. |
| `timeWindow` | `String` | `"past_24_hours"` | Preset window: `past_hour`, `past_24_hours`, `past_7_days`, `past_30_days`. |
| `tsunamiOnly` | `Boolean` | `false` | Only return quakes with active tsunami warnings. |
| `latitude` | `Number` | `null` | Center latitude for radius search (e.g. `35.6762`). |
| `longitude` | `Number` | `null` | Center longitude for radius search (e.g. `139.6503`). |
| `maxRadiusKm` | `Integer` | `500` | Search radius in kilometers. |
| `maxResults` | `Integer` | `50` | Maximum results to return (1 to 500). |

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).
