The National Park service is reopening Jaggar Museum after sulfur dioxide emissions leveled off at Helama'uma'u Crater.

Visitors yesterday were again allowed into the Jaggar Museum area, which will remain open as long as the winds keep sulfur dioxide concentrations within "tolerable limits," the park service announced.

The park restricted access to certain areas in February after the crater emissions climbed, and closed the museum last month after sulfur dioxide levels reached 10 times the normal levels at the summit. Emissions dropped off somewhat over the past week, but remain more than triple the normal level.

A change in wind conditions could again force the closure of the museum and surrounding area.
