## Key points

- A Canary Islands volcano flank could eventually collapse into the Atlantic.
- Worst-case simulations suggest 65-foot waves could reach the US East Coast in nine hours.
- Scientists say any collapse could be centuries or millennia away.

## Summary

A scientist has warned that part of the Cumbre Vieja volcano on Spain’s Canary Islands could eventually collapse into the Atlantic, generating a megatsunami that might reach the US East Coast. The scenario is significant because it could affect distant coastlines, though the timing and scale of any resulting waves remain uncertain.

Volcanologist Professor Bill McGuire’s worst-case computer simulations suggest waves up to 65 feet high could reach the Eastern Seaboard in about nine hours. Researchers cite large boulders in the Bahamas as possible evidence that prehistoric Canary Islands tsunamis crossed the Atlantic. McGuire says a collapse could be centuries or millennia away, and experts stress that the threat is not imminent.
