Earthquake activity at Kilauea Volcano’s summit remains above normal Monday, U.S. Geological Survey Hawaiian Volcano Observatory scientists say.
The scientists also noted that while the activity is above normal, the rate at which the temblors are occurring at the summit has decreased during the past days. In addition, tiltmeters, which are used to measure tiny changes in the slope angle or “tilt” of the ground, showed no significant change in tilt at the summit during the past 24 hours.
On Friday, scientists began monitoring increased earthquake activity at the summit they said may indicate magma accumulating south of the summit caldera.
The summit lava lake at Kilauea Volcano remained out of view from the Jaggar Museum Monday. The lava was about 150 to 165 feet below the rim of the Overlook Crater, which is located on the floor of Halemaumau Crater.
The tiltmeter on the north flank of Puu Oo recorded small fluctuation in tilt during the past 24 hours. Seismicity rates there were normal.
Breakouts along the June 27 lava flow remained active within 5 miles of Puu Oo Thursday morning.
The U.S. Geological Survey Hawaiian Volcano Observatory on March 25 downgraded its alert level for Kilauea Volcano from a “warning” to a “watch.”
