Volcano Watch: Five years flow by; Reflections on the 2018 Kīlauea eruption
Five years ago, volcanic activity at Kīlauea dramatically changed when magma intruded into the lower East Rift Zone or “LERZ.” The summit region experienced 62 total collapse events during the eruption.

usands of residents. The voluminous lava flow had a major impact on the Island of Hawaiʻi, but how does it compare to other lava flow eruptions on Earth in recent history?
Volcano Watch: How does HVO determine which regions are most threatened by lava flows?
The long-term likelihood of an area being invaded by lava in the future, is estimated in two different ways based on the history of lava flow activity. One approach uses a geologic map to calculate how much land surface was covered by lava during different periods going back into the past; the resulting numbers are called coverage rates. Another approach calculates how frequently lava flows have occurred within specific areas over time; the resulting number is a lava flow probability.
Pohoiki Boat Ramp Restoration After 2018 Kīlauea Eruption to Cost Millions
Restoration of a widely-used boat ramp at Pohoiki Bay, in the Puna District of Hawai‘i island, blocked by new sand during the 2018 Puna lava eruption is estimated to take between nine months and six or more years, and cost between $2.5 and $28 million.
