Geologists have had their eye on Kilauea volcano, on Hawaii's Big Island, since March 2018. That's when the Pu'u 'Ō'ō vent began to inflate in size as magma welled up underneath it. Then, in late April, that magma moved southeast of Pu'u 'Ō'ō, erupting in a residential neighborhood.

In this photo, a lava flow emerges from Fissure 22 on May 23. Notice how the lava is flowing downhill, from right to left.

Spooky blue flames burned in Leilani Estates the night of May 22, as lava scorched plants, which in turn produced methane, a colorless gas that burns blue.

By the end of May 21, just a single ocean entry — from Fissure 22 — was active.

The Civil Air Patrol snapped this photo May 20 as lava entered the Pacific Ocean at two different points.

Laze plume

Lava from Fissure 20 reached the ocean late in the evening on May 19. When lava and ocean meet, a white "laze" plume of hydrochloric acid, steam and fine glass particles is created. This laze plume can be hazardous to people nearby and downwind.

An early flight the morning of May 18 allowed photographers to capture the lower, very active part of the fissure system. Notice the ocean in the distance.
