Gandhi attributed the 1934 Bihar earthquake to the sin of untouchability.

Evidence

Gandhi toured the country, preaching against untouchability. He was heckled and attacked by Hindus even more conservative than himself, but he did not swerve from his purpose. Everything that happened was harnessed to the cause of eradicating caste. In January 1934, there was a major earthquake in Bihar. Almost twenty thousand people lost their lives. Writing in the Harijan on 24 February, Gandhi shocked even his colleagues in the Congress when he said it was god’s punishment to the people for the sin of practising untouchability. None of this stopped the Congress party from continuing with a tradition it had invented: it once again fielded mock Untouchable candidates in the 1934 elections to the Central Legislature. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 400
