能拿到什么
Duaer 数据市场里的「地震」：来自美国地质调查局（USGS）目录的全球地震，可按震级、日期及某地周边范围筛选：震级、震源深度、时间、位置与海啸标记。查到结果时用 1 额度，结果交给数字组织的下一个节点。
从节点创建器选 Duaer 数据 → 地震，或打开 数据市场。相关：自然灾害事件、天气预报。
适合做什么
- 查看工厂、供应商或办公室附近的近期地震。
- 为风险报告列出某地区、某时段的强震。
在画布里检索
- 打开节点创建器，选 Duaer 数据 → Earthquakes。
- 至少填一项：Min Magnitude（如 5）、From/To（YYYY-MM-DD）、Place 或 Latitude + Longitude；Radius (km) 默认 500。
- Limit 默认 10，最大 20。执行。
查到结果才扣 1 额度；没有结果、输入有误或上游失败都不扣。
用 API 调用
- GET https://api.duaer.com/v1/data/earthquakes?minMagnitude=6&from=2024-01-01&to=2024-12-31
- Authorization: Bearer <Duaer key>

## When not to use
- Real-time alerting within minutes. The catalog updates within minutes to hours.
- Other hazards such as fires and storms. Use https://skills.duaer.com/natural-events.md.
