As we shared yesterday, Mauna Loa erupted for the primary time since 1984. As we speak, we wished to share a number of the photos and useful data from the primary day.

100 to 200-ft Lava Fountains!

Prior to now 24 hours, the lava exercise has migrated from the summit caldera at Moku’aweoweo to a few fissures close to slightly below the summit on the Northeast Rift Zone. At the newest test on the morning of November twenty ninth, solely one of many three fissure remains to be energetic. From our statement, fissures are usually brief lived.

The fissures from this eruption have produced lava fountains. The estimates for the tallest lava fountain heights are between 100 and 200 toes or 30 to 60 meters. Wow!

Present eruption is posing no threats to native communities

As Hawaii County Mayor Roth acknowledged, “We’ve been instructed that the lava is heading in the absolute best route, which is away from our communities.” Lava is flowing downslope in a northeasterly route. The next map offered by the USGS exhibits the lava location and route. The world is uninhabited and roughly 10 miles away from the principle highways.

Shiny glows seen from miles away

The sight of lava flowing is actually superior! Residents and guests have been in a position to observe a shiny reddish, orangeish glow from Mauna Loa summit from miles away. The eruption has been seen from each the Kona and Hilo sides of Hawaii (Huge) Island.

Right here’s an excerpt from this report from West Hawaii Today,

Resident Sean Sommers was one in every of many residents who ventured out within the wee hours to see the eruption that lit up the night time sky. Whereas pulled off Previous Saddle Street round 5 a.m., he stated Monday’s eruption was the second time he’s witnessed Mauna Loa ship lava down its flanks. He added that his mother-in-law, who lives in Kawaihae, stated she had by no means seen such a shiny glow from the mountain in her lifetime.

“This can be a lot larger than 1984,” the long-time resident stated whereas snapping photographs of the orange glow along with his mobile phone within the cool night time air.

Over the subsequent half-hour, the glow from the summit crater appeared to develop brighter. Round 5:30 a.m., photographs taken by a West Hawaii As we speak editor posted on the Gilbert Kahele Recreation Space confirmed channels or “fingers” of lava forming on Mauna Loa’s northeastern flank. By 5:45 a.m., the channels of lava flowing downslope had been clearly seen because the sky started to lighten within the morning hours.
