"There still remains some activity but on a much lower scale," she said.The earthquakes have all registered as small quakes, with the biggest measuring 4.0 on the Richter scale. "It sure had things rattling in my office," Lane said.Of the roads within the park that were closed on Sunday, Crater Rim Drive, which circles the summit, reopened Monday, according to Lane. The Chain of Craters Road, which descends 18 miles from the summit to the sea, remains closed.The rest of the park remains open, including the Kilauea Visitor Center, Jaggar Museum, the Volcano House Hotel and the Volcano Art Center Gallery. Visitors are being offered free entry to the park.To contact reporter Margaret Myre, send e-mail to email@example.com.
