Thank you to Luis who brought this eruption to our attention. A crater near Kilauea collapsed, causing a new vent to form. What you will see in the photos and video is a fissure vent that is expanding and is now almost a third of a mile long. A fissure vent is simply a linear volcanic vent (forms a line) through which lava erupts, usually without any explosive activity. The vent is usually a few meters long and may be many kilometers long.
Here is a link to the PlanetSave website, which has some great photos and information about the eruption.
