Tiltmeters at Kilauea Volcano’s summit recorded a small decrease in tilt in a direction associated with magma accumulation in the Southwest Rift Zone, the U.S. Geological Survey Hawaiian Volcano Observatory reported Tuesday.
Earthquake activity at Kilauea’s summit and Southwest Rift Zone was at normal background levels during the past day, the observatory’s scientists said. The summit lava lake level rose slightly to about 130 feet below the original floor of Halemaumau Crater. It is currently about 155 feet below the new Overlook Crater rim, which sits on the floor of Halemaumau.
The tiltmeter on the north flank of Puu Oo recorded no significant change 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 Tuesday 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.”
