"This morning it smelled like sulfur so we had to close all the windows," Lindsey Magnani said Thursday as she and her family picked up masks in Volcano, Hawaii. She and her fiance, Elroy Rodrigues, had been sneezing all day, but their children—Kahele Rodrigues, 2, and Kayden Rodrigues, 3 months old—were doing OK.

Authorities handed out around 2,000 masks for protection for people living near the volcano. But geologists have warned that the volcano could become even more violent, with increasing ash production and the potential that future blasts could hurl boulders the size of cows from the summit.
