Volcano Watch - Submarine Kīlauea also impacted by recent events on the volcano

The visible part of Kīlauea from the summit to the Lower East Rift Zone (LERZ) makes up only a small portion of the total volcano. Much of Kīlauea lies beneath the sea, including the Puna ridge to the east, and the south flank extending offshore beyond the southern coastline.
