This animated GIF shows a sequence of radar amplitude images that were acquired by the Italian Space Agency's Cosmo-SkyMed satellite system. The series shows changes to the caldera area of Kīlauea Volcano that occurred over May 5 at 6:12 a.m. HST, May 17 at 6:12 a.m.

Tephra (airborne lava fragments) erupted by the high lava fountains of fissure 8 was carried downwind, where the frothy rock fragments fell on Leilani Street, just past Kupono Street, in the Leilani Estates subdivision.

Scientists on the early morning overflight of Kīlauea Volcano's lower East Rift Zone documented a very weak ocean entry. For the easternmost lobe, only a few small finger channels of lava were entering the ocean.

Close view of weak ocean entry at about 1:05 p.m. HST. Only small and intermittent "laze" plumes have been observed today.

View of the now-sluggish lava flow that crossed Pohoiki Road earlier today; the flow originated from fissure 8. This fissure was very active overnight, slowed this morning, and stopped by about noon.

Map as of 3:00 p.m. HST, May 28, 2018. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

View of the fissure complex looking toward the southwest (uprift) during this afternoon's overflight at about 1:15 p.m. HST. The small lava flows spreading to the southeast from the fissure complex (lower middle) originate in the area of between fissures 16 and 18.

View of the fissurecomplex is toward the southeast during this afternoon's overflight of the lower East Rift Zone at about 1:15 p.m. HST. The lava channel in middle of photograph is filling with lava erupted from fissure 22.

Close view of lava channel in middle of the lava flow erupting from fissure 8 during this morning's overflight at about 7 a.m. HST. The tallest lava fountain is fissure 8, active since yesterday evening. The eruption rate at fissure 8 diminished significantly later in the morning.

Aerial view of active lava flow crossing Pohoiki Road during an overflight this morning about 7 a.m. HST. Pohoiki Road cuts through middle of photograph.

Aerial view of the eastern-most end of the fissure complex (top right) and active lava channels and inactive flows south of the fissures (toward left side of photo) at about 12:30 p.m. HST; the ocean is out of view left side of photo. In this view, fissure 22 in top right is supplying most of the lava to the active channel.

This image shows radar data acquired by the European Space Agency's Sentinel-1 satellite over Kīlauea Volcano on May 19 at 6:30 PM HST (left) compared to May 25 at 6:30 PM HST (right). The satellite transmits a radar signal toward the surface and measures the strength of the return, with bright areas indicating a strong return and dark areas a weak return.

Aerial view of the ocean-entry areas at about 12:30 p.m. HST. Lava flowing into the ocean diminished overnight and this morning (note lack of obvious plume at the entry areas). View is toward the northwest.
