(CNN) —  

Rusty and Jenny Perry fled their home in Hawaii’s Big island last month to escape bubbling lava following the Kilauea volcano eruption.

Lava has also destroyed 467 homes, the agency said. A disaster recovery center, located inside a high school gym, and two shelters are open to the public.

Lava flowing in to the ocean can create “laze,” a mash-up of lava and haze that occurs when hot lava hits the ocean, sending hydrochloric acid and volcanic glass particles into the air.

Fissure 16 is oozing lava, the observatory said, and is being monitored closely. The National Weather Service reported heavy vog, or volcanic smog, blanketing the inner and southern parts of the island.

A 5.3-magnitude earthquake centered in the summit region of Kilauea hit the island of Hawaii on Friday afternoon, the Civil Defense officials said. It was not large enough to cause a tsunami. A small ash plume, caused by the Kilauea summit ash eruption, reached 9,000 to 10,000 feet high and affected surrounding areas.
