爆発
ばくはつ
- flat (heiban)
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
explosion, detonation, eruption
Bakuhatsu is Middle Chinese 爆發, literally “burst, explode + fly or send forth”.
