Quick Start

// Initialize monitoring
await init({ location: "大理" })

// Get latest earthquakes
await getAll()

// Start proactive monitoring
await start()

Data Sources

API Reference

init(options)

Initialize configuration.

await init({
  location: "dali",           // City name (supports pinyin, abbreviations)
  distanceThreshold: 300,     // Alert distance in km
  minMagnitude: 3.0,         // Minimum magnitude
  language: 'zh',            // Language: zh/en/ja
  sources: {                // Toggle data sources
    CENC: true,
    JMA: true,
    CWA: true
  }
})

getAll(options)

Get earthquakes from all sources.

const result = await getAll({ limit: 5 })
// Returns: { earthquakes, totalCount, nearbyEarthquakes, hasAlert, alertMessage }

getCENC(limit)

Get China earthquake data.

const { earthquakes } = await getCENC(10)

getJMA(limit)

Get Japan earthquake data.

const { earthquakes } = await getJMA(10)

getCWA()

Get Taiwan earthquake early warning data.

const { earthquakes, isWarning } = await getCWA()

start(options)

Start proactive monitoring with auto-alerts.

await start({ interval: 60000 })  // Check every 60 seconds

stop()

Stop monitoring.

await stop()

config(newConfig)

View or update configuration.

// View
const cfg = await config()

// Update
await config({ language: 'en', minMagnitude: 4.0 })

cities()

List all supported cities with coordinates.

const { cities } = await cities()

Configuration Options

Supported Cities (20+)

Location Matching Examples

All these return Beijing:

await init({ location: '北京' })      // Chinese
await init({ location: 'beijing' })   // Full pinyin
await init({ location: 'bj' })        // Abbreviation
await init({ location: 'bei' })       // Partial match

Multi-Language Alerts

Alert language is automatically selected based on earthquake source:

Manual Language Override

// Set preferred language (applies to alert format)
await init({ language: 'en' })

// All alerts will be in English regardless of source

Alert Message Format

⚠️ Earthquake Alert!
📍 Epicenter near Dali:

1. 🔴 M7.6级 [中国地震台网]
   📍 汤加群岛
   📏 Distance: 5000km
   ⏰ 2026-03-24 12:37:50
   📊 Depth: 250km

Please stay safe!

Security

Webhook URLs are encrypted using AES-256-CBC before storing in config file:

// Set webhook (automatically encrypted)
await config({ webhook: 'https://oapi.dingtalk.com/robot/send?access_token=xxx' })

// Stored encrypted, decrypted only in memory

Performance

Shared Cache

• Reduces redundant API calls
• TTL-based expiration (1 minute default)
• Auto-cleanup every 5 minutes

Parallel Fetching

• All three data sources fetched simultaneously
• Fast response time

Return Format

{
  timestamp: "2026-03-24T14:30:00.000Z",
  sources: [
    { source: "CENC", sourceName: "中国地震台网", count: 10, earthquakes: [...] },
    { source: "JMA", sourceName: "日本气象厅", count: 5, earthquakes: [...] }
  ],
  earthquakes: [...],      // Merged, sorted by time
  totalCount: 15,
  nearbyEarthquakes: [...], // Within distanceThreshold
  hasAlert: true/false,
  alertMessage: "..."       // Formatted alert string
}
