MAUNA LOA (VNUM #332020)
19°28'30" N 155°36'29" W, Summit Elevation 13681 ft (4170 m)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: RED

The Northeast Rift Zone eruption of Mauna Loa continues, with two active fissures feeding lava flows downslope. The fissure 3 lava flows are travelling to the north, still moving toward the Daniel K. Inouye Highway (Saddle Road). Fissure 3 remains the dominant source of the largest lava flow. Advance of the largest flow slowed between 7 a.m. and 12:30 p.m. HST today to a rate of 0.02 miles per hour (24 meters per hour). As of 12:30 HST p.m. today, the flow front remained about 3.6 miles (5.8 km) from the Daniel K. Inouye Highway (Saddle Road).  The flows are reaching a relatively flat area and are beginning to slow down; as this happens, the lava flow will spread out and inflate. Forecasts indicate it may take two days for lava flows to reach the Daniel K. Inouye Highway (Saddle Road).

Fissure 4 is still active with lava flows moving toward the northeast. A small lobe is moving to the east from fissure 4 at a slower rate than the main lobe. Volcanic gas plumes are lofting high and vertically into the atmosphere. Pele's hair (strands of volcanic glass) is falling in the Humu‘ula Saddle area.

Our seismic monitoring detects tremor (high rates of earthquakes) in the location of the currently active fissures. This indicates that magma is still being supplied, and activity is likely to continue as long as we see this signal.

There is no active lava within Moku'āweoweo caldera, and the Southwest Rift Zone is not erupting. We do not expect any eruptive activity outside the Northeast Rift Zone. No property is at risk currently.

Mauna Loa began erupting about 1130PM Sunday, November 27, 2022.  Lava is flowing into the NE rift zone above Hilo.  Video looks south from Saddle Road, Hilo is to the left about 20 miles.  The flow is far from any habitations ....

MAUNA LOA (VNUM #332020)
19°28'30" N 155°36'29" W, Summit Elevation 13681 ft (4170 m)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: RED

Activity Summary:

The Northeast Rift Zone eruption of Mauna Loa continues, with several fissures and lava flows active. Several lava flows are traveling in a northeast direction. The longest and largest lava flow is issuing from fissure 3. This lava flow crossed the Mauna Loa Weather Observatory Road at approximately 8 p.m. yesterday evening, November 29, and the flow front was located approximately 6 miles (10 km) from Saddle Road at 7 a.m. HST this morning.

This morning, fountains at fissure 3 are up to 25 m (82 ft) and fountains are fissure 4, which formed at approximately 7:30 p.m. HST last night, were 5-10 m (16-33 ft) tall.

There is no active lava within Moku'āweoweo caldera, and there is no lava erupting from the Southwest Rift Zone. All lava flows are on the northeast flank of Mauna Loa.  We do not expect any eruptive activity outside the Northeast Rift Zone. No property is at risk currently. There is a visible gas plume from the erupting fissure fountains and lava flows, with the plume primarily being blown to the North.

Residents with questions about emergency response and resources that may be available to assist those at risk should consult LINK.

Hawai‘i Volcanoes National Park has closed the Mauna Loa Road from Kīpukapuaulu and the closure extends to the summit caldera; for more information please see https://www.nps.gov/havo/index.htm.

HVO/USGS Volcanic Activity Notice
Volcano: Mauna Loa (VNUM #332020)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: RED
Issued: Monday, November 28, 2022, 7:20 AM HST
Source: Hawaiian Volcano Observatory
Notice Number: 2022/H603
Location: N 19 deg 28 min W 155 deg 36 min
Elevation: 13681 ft (4170 m)
Area: Hawaii
Volcanic Activity Summary:

The eruption of Mauna Loa has migrated from the summit to the Northeast Rift Zone where fissures are feeding several lava flows. HVO staff on an overflight at approximately 6:30 a.m. HST confirmed fissures at high elevations within Hawai‘i Volcanoes National Park are feeding lava flows upslope of the Mauna Loa Weather Observatory. Lava flows are not threatening any downslope communities and all indications are that the eruption will remain in the Northeast Rift Zone. Volcanic gas and possibly fine ash and Pele's Hair may be carried downwind.

Residents at risk from Mauna Loa lava flows should review preparedness and refer to Hawai‘i County Civil Defense information for further guidance.    

Based on past events, the early stages of a Mauna Loa rift zone eruption can be very dynamic, and the location and advance of lava flows can change rapidly.    

HVO is in close consultation with emergency management partners and will monitor the volcano closely to provide further updates on activity.

Background:

Since the mid-19th century, Mauna Loa’s Northeast Rift Zone has erupted eight times: in 1843, 1852, 1855–1856, 1880–1881, 1899, 1935–1936, 1942, and 1984. Lava flows from the Northeast Rift Zone can travel in north, west, northwest, south, and southwest directions.
