What do we call new land at Kīlauea's ocean entries?

Kīlauea Volcano's Kamokuna lava delta on October 6, 2017. Multiple streams of lava entering the ocean on both sides of the delta created small plumes of laze (lava haze). The visible part of the delta, which is deceptively stable, was built by many small lava flows accumulating on an unstable foundation of unconsolidated volcanic rock fragments. USGS photo by L.
