Two new fissures opened on Hawaii’s Kilauea volcano, hurling bursts of rock and magma with an ear-piercing screech on Sunday, threatening nearby homes and prompting authorities to order new evacuations. One new fissure from Sunday morning was a vivid gouge of magma with smoke pouring out both ends and was the 17th to open on the volcano since it began erupting on May 3. Some 37 buildings have been destroyed and nearly 2,000 people ordered to evacuate in the past 10 days.
