Lava erupted continuously within Puu Oo over the past week, feeding a small lava lake in the center of the crater. Changes in eruptive output commonly resulted in overflows from the lake that slowly built up the crater floor, which is about 53 m (175 ft) below the east rim of Puu Oo.
No lava is erupting outside the crater.
A small lava lake was also present deep within the Halemaumau Overlook vent during the past week, with minor fluctuations in lava level. Volcanic gas emissions remain elevated, resulting in relatively high concentrations of sulfur dioxide downwind.
One earthquake beneath Hawaii Island was reported felt this past week.
A magnitude-2.1 earthquake occurred at 3:48 p.m. Friday, May 6 and was located 5 km (3 mi) southwest of Honomu at a depth of 45 km (28 mi).
