View toward the southeast of lava erupting from a spatter cone on the northeast part of the Pu‘u ‘Ō‘ō crater floor. The Pu‘u ‘Ō‘ō Webcam is visible on the rim of the crater near the bottom of the photo.

A third view of the erupting spatter cone, from the south.

This composite image shows the west lobes that are active on the coastal plain. The east lobe, shown in the other composite image, extends of view to the right. Like the other composite image shown today, hot colors (yellow, white) show active areas of the flow field, while the cooler colors (red, purple) show recent but inactive flows.

Aerial view of Pu‘u ‘Ō‘ō crater, looking north-northeast. New flows, erupting from a spatter cone just above the center of the photo and a spatter cone to the left of center, have been slowly filling the crater over the past few months.

Viewing looking northeast across Pu‘u ‘Ō‘ō crater. The spatter cone erupting lava flows on to the crater floor over the past few weeks, visible just above the center of the photo, tops the low mound of lava that it has constructed.

Aerial view of the Ki ocean entry with several narrow streams of lava pouring into the ocean.

Spatter being ejected from the newly formed vent.

The lava pond in the vent cavity of the Halema‘uma‘u Overlook vent during the rise phase of a rise/fall cycle. In this photo, the lava pond is 95 m (312 ft) below the floor of Halema‘uma‘u crater. When the pond level is high there is very little fume, allowing for unusually clear views.

A small lava flow erupted from the septum between two vents on the east wall of Pu‘u ‘Ō‘ō crater on Sunday, February 6. The hole on the right, which is no longer active, was the original east wall vent. The fuming hole behind the new lava flow is the current east wall vent.

Flows from the more northerly vent are crossing a small portion of the crater floor and filling in the southern opening.

A close-up of the northeast vent in Pu‘u ‘Ō‘ō, spattering and sending lava flows into the crater.

Overflows from the lava pond in Pu‘u ‘Ō‘ō have nearly leveled the crater floor with the perched pond. The floor of the crater is now 39 m (128 ft) below the east rim.

A view of Moku‘āweoweo, the summit caldera of Mauna Loa, as seen from South Pit (looking to the north-northwest). An eruption in 1940 created the cinder-and-spatter cone visible on the caldera floor (right center). This cone, which is about 114 m (373 feet) high, is the largest cone at Mauna Loa's summit.

An aerial view of the 1940 cinder-and-spatter cone on the floor of Mauna Loa's summit caldera as seen from the southeast. The west wall of the caldera (background) is about 170 m (560 feet) high. Most of the caldera floor around the cone is covered by lava flows erupted in 1984.

This view of Mauna Loa's summit is looking toward the northeast. The east flank of Mauna Kea is to the left, and North Pit, on the northeast end of Moku‘āweoweo, is straight ahead.

The 1940 cinder-and-spatter cone as seen from the caldera floor looking to the southeast. This cone, which is about 114 m (373 feet) high, was built around the vent as lava spewed from it over a period of 134 days. The dark-colored pāhoehoe flows visible in the foreground were erupted in 1984.

The floor of Pu‘u ‘Ō‘ō crater continues its slow rise as lava pours out of a new vent at the base of the east wall. The height of the floor has risen 20 m (66 ft) over the past two weeks.

A low-angle view of the perched lava lake shows how it is elevated above the floor of the crater, like an above-ground swimming pool. The levee around the stands some 8-10 m (26-33 ft) above the surrounding crater floor. Also visible as the bottom of the photo is a new vent which began erupting around midnight last night on the western edge of the crater floor.

View looking up Mauna Loa's spectacular Southwest Rift Zone. Pu‘u o Keokeo fills the lower half of the photo. The black lava beyond is mostly from 1916 and 1926. The summit of Mauna Loa is in the background.

Sulfur, not snow, paints the ground white in the Sulfur Cone area on Mauna Loa's upper Southwest Rift Zone. The summit of Mauna Loa is over the slope of the mountain out of sight to the left in the background.

Shield-volcano Mauna Kea viewed from the northern slope of Mauna Loa (cinder cones in the foreground) shows off its broad shield shape. The bumps on its profile are large cinder cones.
