Mauna Loa update: unrest continues, but the outcome is uncertain

Aerial view of Mauna Loa erupting on the morning of March 25, 1984, the first day of the volcano's most recent eruption. The lava flow was advancing southeast, toward Kīlauea, from fissure vents at an elevation of about 11,200 feet on Mauna Loa's Northeast Rift Zone. Moku‘āweoweo, Mauna Loa's summit caldera, is visible at top left.
