Nighttime view of fissure 8 lava as it exits the vent and feeds into the channel.

View from the bank of the cooling lava channel near the Leilani Estates subdivision. The height difference between the channel (right) and upper bank (left) is about 8 m (26 ft). Although lava is not flowing from fissure 8, the lava flow field includes large areas of still-hot, rugged, and unstable lava surfaces.

Elkhorn Slough is a tidal river delta, salt marsh, and estuary in Monterey County, California. It is near the community of Moss Landing and is fed by Carneros Creek.

The offices of the USGS Pacific Coastal and Marine Science Center are just a few hundred feet north, outside the bottom portion of the photograph.

This morning, USGS scientists flying over fissure 8 noticed a change in the vent from yesterday. Gas jets were throwing spatter—fragments of glassy lava (light gray deposits)—from small incandescent areas deep within the cone. This activity is an indication that the lower East Rift Zone eruption may be paused rather than pau (over).

Data from continuous GPS stations indicate how the ground is moving over time. Station WLWY, near White Lake on the Sour Creek resurgent dome in Yellowstone caldera, has been operating since 2001. This plot shows vertical ground motion recorded at the site.

View from this morning's helicopter overflight of the Pohoiki boat ramp at Isaac Hale Park shows black sand, transported to the southwest by longshore currents, blocking the entrance to the small boat harbor.

Groundwater occurs in the saturated soil and rock below the water table. If the aquifer is shallow enough and permeable enough to allow water to move through it at a rapid-enough rate, then people can drill wells into it and withdraw water.

Lava continues to ooze into the ocean at scattered entries along the Kapoho (pictured) and Ahalanui lobes.

A sand bar has built up at the end of the Pohoiki boat ramp, but the ramp itself remains intact and there has been no significant lava advance toward the ramp in recent days.

Today's morning overflight saw no new activity at any of the fissures in the lower East Rift Zone. Fissure 8 had only a sluggish lava puddle remaining in the cone, and other fissures, though steaming, showed no signs of reactivation.

Fissure 8 may have slowed down, but HVO scientists are still on the ground in Leilani Estates, monitoring old ground cracks and marking ones that haven't been surveyed before. Monitoring these cracks over multiple days could detect any new signs of magma movement beneath the ground, one of the indicators that fissures might reactivate.
