Lava continues to cool at Kīlauea summit following short-lived eruption

According to Hawaiian Volcano Observatory, it is unlikely that the recent eruption will resume based on the behavior of past, short-lived summit fissure eruptions at Kīlauea summit in 1982, 1975, 1974, and 1971, which all ended abruptly.

Kīlauea eruption drew visitors to Hawaiʻi Volcanoes National Park during usually slow time

At least 5,000 visitors — and likely sometimes more — came each day of the eruption to see the volcanic activity from Sept. 10-16.

Living on Kīlauea — one of world’s most active volcanoes — involves risk, mitigation efforts

The people living in Puna and Hawai’i County understand the risk. Knowing they aren’t in control and can’t stop nature from happening is the first step to becoming resilient in the face of future volcanic eruptions on the Big Island.
