## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## Japan Volcano Warnings & Activity Data

Real-time Japan volcano warnings, eruption alerts, and activity reports scraped from the Japan Meteorological Agency (JMA). Covers all active volcanoes in Japan with alert levels, eruption warnings, and detailed activity information.

### What Data Does This Actor Provide?

- **Volcano Warnings**: Current eruption warnings and alert levels for all monitored Japanese volcanoes (Sakurajima, Mt. Fuji, Mt. Aso, Kirishima, etc.)
- **Activity Reports**: Regular volcano activity status updates and observation summaries
- **Alert Levels**: JMA 5-level volcanic alert system (Level 1-3 + special warnings)
- **Real-time Updates**: Data sourced directly from JMA official APIs

### Use Cases

- **Disaster monitoring & early warning systems**: Integrate real-time volcano alerts into emergency response platforms
- **Academic research**: Analyze historical eruption patterns and volcanic activity trends across Japan
- **Travel safety applications**: Provide travelers with current volcano alert levels near their destinations
- **Insurance & risk assessment**: Monitor volcanic risk levels for property and travel insurance models
- **News & media monitoring**: Automated tracking of volcano status changes for reporting

### Input Parameters

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|

| `max_results` | integer | `100` | Maximum results (1-5000) |
| `log_level` | string | `"INFO"` | `DEBUG`, `INFO`, `WARNING`, or `ERROR` |

### Output Schema

# 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';
