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.
