March 1961 Halemaʻumaʻu Eruption

The March 1961 eruption at Halemaʻumaʻu was the second of three summit eruptions at Kīlauea that year, marked by renewed lava activity within the northeast collapse pit formed in February. This phase featured vigorous lava fountaining, crater floor uplift, and the gradual infilling of the pit, reflecting continued magma supply and dynamic summit processes.
