So far, lava has destroyed 82 Hawaii structures

The lava is still "moving very vigorously," keeping Big Island residents on alert and away from the ocean.

HONOLULU — Hawaii County officials say the number of structures lava has destroyed on the Big Island is now 82.

County Managing Director Wil Okabe told The Associated Press Friday that the number includes about 37 homes. He says officials used property records to determine which structures are homes because it can be difficult to tell from aerial surveys.

The Kilauea volcano has been erupting for three weeks, spewing lava from cracks that emerged in neighborhoods and sending ash sky-high from its summit. Earthquakes also have been occurring.

About 2,000 people were ordered to evacuate from the rural communities where the lava fissures opened.
