HONOLULU (KHON2) — Mauna Loa continues to spew lava from two fissures, named fissure 3 and fissure 4, with the flow traveling northeast.

Fissure 3 is now the longest flowing since fissures 1 and 2 went inactive Monday. Lava from fissure 3 crossed an access road to the Mauna Loa Weather Observatory Monday night at approximately 8 p.m.

According to the HVO, the fourth fissure formed at around 7:30 p.m. on Monday in the northeast rift zone.

Fountaining from fissure 3 are consistently reaching 131 – 164 feet and fissure 4 is reaching 16 – 33 feet.

The Northeast Rift Zone eruption of Mauna Loa has continued into its second full day. At this time two fissures are active, sending lava flows in multiple directions. Overnight satellite views allowed USGS analysts to accurately map some of the most active flows, displayed in red here. Further downslope progression of the flows this morning is marked by dashed lines and points for the flow fronts at 12:00 p.m. today. As of that time, the most downslope flow is within 5.5 miles (9 kilometers) of Saddle Road. (Courtesy USGS)

The USGS said there are no current threats to surrounding communities. It is not expected that eruptive activity will happen outside the northeast rift zone.

The front of the flow was approximately 4.5 miles, in a straight line distance, from Saddle Road at 3:30 p.m.
