Hawaii Volcanoes National Park has been temporarily shut down because because high levels of sulfur dioxide spewed by an eruption of Kilauea Volcano. Kilauea Volcano has been belching ash and gas for a couple of weeks. The rare eruption involves something deep inside Kilauea, and includes lava being ejected from the vent by powerful gas and water pressure. Some ash has been falling in Pahala, one of several towns in the area, for weeks. Officials have encouraged folks to stock up on emergency items such as dust masks.
A couple days before the ash and gas eruption, an explosion on the crater's rim blew debris over a 75-acre area. The explosion carved out a small crater in the rim.
