Kana-mixed spelling, sometimes used for readability or when the kanji 轟 is not preferred.
Compound of 鳴り (nari, 'sounding') + 轟く (todoroku, 'to roar, reverberate'). The exact historical derivation is uncertain, but the form follows a common pattern of intensifying a verb with a prefixed nominal element.
