## 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

## Japan Earthquake Data

Real-time and historical earthquake data from Japan Meteorological Agency (JMA). All 47 prefectures with magnitude, depth, seismic intensity. Output in English.

### What does this actor do?

This actor extracts structured data and outputs it in a clean, machine-readable JSON format. All results are available via the Apify API and can be exported to CSV, JSON, Excel, and other formats.

### Use cases

- Real-time earthquake monitoring for Japan
- Seismic risk analysis and research
- Travel safety alerts for Japan tourism
- Insurance and reinsurance risk assessment
- Earthquake data visualization and mapping
- Building and infrastructure safety compliance

### Data source

Japan Meteorological Agency (JMA) official public API. Data is freely available under the Public Data License (compatible with CC BY 4.0). Source attribution required.

### Input parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| Minimum Magnitude | number | No | - | Filter earthquakes by minimum magnitude (e.g., 3.0 for M3.0+). |
| Minimum Seismic Intensity | integer | No | - | Filter by minimum JMA seismic intensity scale (1-7). |
| Prefecture Filter | string | No | - | Filter by affected prefecture name in English (e.g., 'Tokyo', 'Osaka'). Leave empty for all. |
| Max Results | integer | No | 50 | Maximum number of earthquake records to return. |
| Log Level | string | No | INFO | Logging verbosity. Options: `DEBUG`, `INFO`, `WARNING`, `ERROR` |

### Output format

Each result item contains the following fields:

```json
{
    "city_code": "...",
    "max_intensity": "...",
    "prefecture_code": "...",
    "prefecture_name": "...",
    "max_intensity": "...",

    "detail_json_url": "...",
    "source": "...",
    "Format": "...",
    "PREFECTURE_CODES": "..."
}
```

### How to use

#### Via Apify Console

1. Navigate to this actor's page on Apify Store
2. Configure the input parameters
3. Click **Start** and wait for the run to complete
4. Download results from the **Dataset** tab

#### Via Apify API

```python
from apify_client import ApifyClient

client = ApifyClient("<YOUR_API_TOKEN>")
run = client.actor("<ACTOR_ID>").call(run_input={
    "max_results": 100
})

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)
```

### Integrations

This actor can be connected to various cloud services and web apps using integrations. You can integrate with services like Google Sheets, Slack, Zapier, Make, GitHub, and many more.

### Pricing

This actor uses a pay-per-result pricing model at approximately $5 per 1,000 results. Actual costs may vary based on the complexity of the data extraction.

## CLI example

```bash
echo '{}' |
apify call shiokoshi356/japan-earthquake-data --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,shiokoshi356/japan-earthquake-data"
        }
    }

```

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).
