Which increased hazard arises when pyroclastic surge encounters seawater?

💡 Explanation

Violent steam explosions result because rapid heating of seawater by the pyroclastic surge causes instantaneous steam formation, resulting in a surge. Therefore, lateral blasts are likely, instead of merely vog, which involves gas diffusion rather than explosions.
