On March 26 at 午後11時18分ごろ (gogo juuichi-ji juuhappun goro), around 11:18 P.M., a somewhat strong earthquake struck 岩手県で (Iwate-ken de), Iwate Prefecture, recording a maximum seismic intensity of 4.

A Late-Night Earthquake in Iwate

According to reports, on the night of the 26th, a やや強い地震 (yaya tsuyoi jishin)—a somewhat strong earthquake—occurred in Iwate Prefecture.

The earthquake reached a 最大震度4 (saidai shindo yon), meaning the greatest seismic intensity observed was level 4 on Japan’s scale. The shaking was officially 観測する (kansoku suru), or measured, at this level.

The key details reported were:

• Date: March 26
• Time: Around 11:18 P.M.
• Location: Iwate Prefecture
• Maximum seismic intensity: 4

Even in short news bulletins like this, Japanese reports are very precise about time, place, and measurement.

Understanding Earthquakes in Japan

Japan uses a unique system called 震度 (shindo), or seismic intensity, to describe how strongly the ground shakes at a specific location. This is different from magnitude, which measures the total energy of an earthquake.

When news reports say 最大震度 (saidai shindo), they mean “the maximum seismic intensity observed” in affected areas.

A level 4 on the Japanese scale is noticeable and can feel strong, but it is not among the most severe levels. The wording やや強い (yaya tsuyoi) literally means “somewhat strong” or “rather strong,” softening the description slightly.

Because earthquakes are common in Japan, news reports are typically concise and factual, focusing on measurable data such as time, place, and 観測する (kansoku suru) results.

Vocabulary

Notice how these words combine to form compact news expressions like:

• 最大震度4 (saidai shindo yon) — maximum seismic intensity 4
• やや強い地震 (yaya tsuyoi jishin) — a somewhat strong earthquake

Japanese news writing often stacks nouns together without extra words, which is why reading practice is so important.

Grammar Spotlight

1. 〜ごろ (around, about a time)
