Lava from Kilauea on Hawaii flows into the ocean. I shot this picture in October 2017. More on my website volcanoes.de.

Aerial view, from the east, of waning lava fountain from Pu'u 'O'o on Hawai'i Island's Kilauea Volcano. Taken at the end of eruption episode 32. Pu'u 'O'o rose 209 meters above the pre-1983 surface (928 meters above sea level).

I was visiting the Big Island of Hawaii with some friends and family, and my brother convinced the group to take a lava tour by boat. I always kind of balk a little bit at overtly touristy stuff like that, but I think everyone was a pretty shocked when we got our first look at the Kalapana Lava Flow after about a half hour boat trip down the coast.
It’s such an awesome, phantasmagorical sight and, since they actually get surprisingly close to the spots where the rivers of lava meet the ocean and throw up sulfurous steam clouds, also a pretty visceral sensory experience.

Forest of lava trees resulting from eruption of a 1-km-line of vents east of Pu'u Kahaulea on Hawai'i Island's Kilauea Volcano. The bulbous top of each lava tree marks the high stand of the lava flow as it spread through the trees. As the fissure eruption waned, the flow continued to spread laterally; its surface subsided, leaving pillars of lava that had chilled against tree trunks. Spattering is from fissure out of view to the left. Note blob of spatter adhering to the top of the stripped 'ohi'a tree.
