💡Pro Tip
Distinguishing 注意報 from 警報
注意報 (advisory) is a lower-level alert than 警報 (warning). An advisory suggests caution but does not indicate imminent danger, while a warning signals higher risk requiring immediate action.
⚡Gold Rule
When to take action
Even during an advisory, prepare emergency supplies and secure heavy objects, as conditions can escalate quickly.
📖Word Origin
地震 (jishin, earthquake) + 注意 (chūi, caution/advisory) + 報 (hō, report/announcement). The term combines native Japanese morphemes to describe a specific type of seismic alert.
📝Usage Notes
Commonly used in Japan's disaster prevention system. The Japan Meteorological Agency (JMA) issues different levels of earthquake alerts, with 注意報 being the second-lowest level (after 予報 and before 警報).
