The lava lake at the summit of Hawaii's Kilauea volcano rose over the weekend, according to the Hawaiian Volcano Observatory, reaching within 13 feet of its Overlook crater rim on Sunday.
Kilauea, described as the world's most active volcano, is located on the southern shore of Hawaii.
The lava lake had risen 26 feet since Saturday, scientists reported, coming within 13 feet of spilling over the Overlook crater rim onto the floor of the Halema`uma`u crater. However, the lava level was about 20 feet below the rim by 7AM local time Sunday.
The summit lava lake is within an elliptical crater, known as the Overlook crater, which measures approximately 520 feet by 690 feet.
The Overlook crater has been more-or-less continuously active since it opened on March 19, 2008, according to the Hawaiian Volcano Observatory. Since 2013, the lava level has been typically between 100 feet and 200 feet below the floor of the Halemaʻumaʻu crater.
The Hawaiian Volcano Observatory also noted elevated seismic activity beneath the summit and the volcano's upper East and Southwest Rift Zones.
