A 5.0‑magnitude tremor rattled Tsukuba on Wednesday night, sending India's athletics contingent scrambling from their rooms.
The quake lasted only 30–60 seconds but was powerful enough to shatter the hotel’s walls, causing several athletes to spill into the corridor.
No injuries were reported, and officials said the building suffered no damage.
Meanwhile, Typhoon Dujuan is set to hit the coast on Monday, and heavy rains have already battered Nagoya, raising concerns over the upcoming Games.
Coaches assured that training will resume, and the Indian team remains focused on their debut in Nagoya on Saturday.
