Viewing recommendations for Mauna Loa

For the first time since 1984, Kīlauea and Maunaloa are erupting side-by-side which is expected to draw an influx of visitors to Hawai‘i Volcanoes National Park who hope to see this rare event. The Hawaiʻi Tourism Authority provided the following updates:

At approximately 11 p.m. Tuesday, the leading edge of the Mauna Loa lava flow crossed Old Kona Highway, a dirt road that crosses the Mauna Loa Forest Reserve. These images show the leading edge of the eruption.

HVO: Mauna Loa flow is similar to 1984 eruption; Long-term forecast discussed

“Eventually, this kind of lava flow is very similar to what happened in 1984, and could potentially threaten populated areas around Hilo. But we’re looking at somewhere around a week before we expect lava to get anywhere near that direction. We’re hoping that it will parallel the 1984 eruption and become more viscous as time goes on… hitting flatter slopes around the Saddle that slow it down,” said Hon.

“We do not expect upper fissures to reactivate. However, additional fissures could open along the Northeast Rift Zone below the current location, and lava flows can continue to travel downslope,” HVO scientists said.
