THE NEARLY SIMULTANEOUS SHUTDOWN OF MAUNA LOA AND KILAUEA ERUPTIONS is the subject of this week's Volcano Watch, written by scientists and affiliates of USGS Hawaiian Volcano Observatory:
The Island of Hawai'i recently went from having two actively erupting volcanoes that caught the attention of both local residents and the world, to having none. However, our volcanoes are still active and will erupt again, so volcano awareness should not be put on the backburner, so-to-speak. When volcanoes in Hawai'i aren't erupting, it is time to consider (and prepare for) where and when the next eruption could be.
For decades, Kīlauea was the only erupting volcano in Hawai'i, but it is one of six active Hawaiian volcanoes that HVO monitors! Mauna Kea erupted several thousand years ago, Haleakalā erupted several hundred years ago, Hualālai erupted a couple of centuries ago, Kama'ehuakanaloa (formerly Lō'ihi Seamount) erupted in 1996, and—until very recently—Mauna Loa had last erupted in 1984.

Volcano Awareness Month programs will address this question and others. Join us at one of the events being offered in Hilo, Kailua-Kona, Ocean View, Pu'uhonua o Hōnaunau National Historic Park, and Hawai'i Volcanoes National Park. Or take some time during the month of January to personally reflect on how volcanic activity in Hawai'i can impact you.
Mauna Loa's recent eruption has reminded Island of Hawai'i residents and visitors that emergency preparedness cannot be overemphasized. An important aspect of preparedness is being aware of the hazards that can impact you where you live but also where you work and your commute.
The Mauna Loa eruption threatened the Danial K. Inouye Highway (Saddle Road), a major thoroughfare connecting the east and west sides of the Island of Hawai'i. From the Highway, views of the eruption were spectacular and a stark reminder of how life on the Island of Hawai'i can be impacted very quickly by volcanic activity.
Fortunately, the lava flow-front stalled, and the Northeast Rift Zone eruption of Mauna Loa ended before the highway was impacted. But consider how your life might have changed had the eruption continued and covered the road. It's important to remember that Mauna Loa's slopes cover more than half of the Island of Hawai'i and future eruptions have the potential to directly impact almost every district on the island.
This Mauna Loa eruption accompanied an eruption within Halema'uma'u crater at the summit of Kīlauea. While there were signs that the Kīlauea eruption was waning before the Mauna Loa eruption began, lava supply appears to have ceased for both eruptions within about a day. What does that mean for future volcanic activity?
We know that the two volcanoes have separate shallow magma systems but it's possible that they influence one another through stresses associated with their eruptions—essentially, when one volcano expands or contracts, it puts pressure on or off the other volcano.
Though lava supply to Halema'uma'u appears to have paused, passive overturns of the lava lake surface continue as the dense cool crust sinks beneath the hot and buoyant magma below. During these overturns, the molten material beneath Halema'uma'u crater floor is temporarily exposed, making it appear that the eruption has resumed.
Now, HVO staff and residents are wondering what will happen next? Will Mauna Loa will take another long break or enter a phase of more frequent eruptions? Will the lava lake at Kīlauea summit start to grow again? We'll be monitoring the volcanoes closely for clues and keep you informed.

Volcano Activity Updates
Mauna Loa is not erupting. Its USGS Volcano Alert Level is at ADVISORY. Mauna Loa updates are issued weekly on Thursdays.
Webcam imagery shows residual incandescence and no lava movement in the fissure 3 vent on the Northeast Rift Zone. The inactive main flow front still glows at a few spots at night and may inch northward very slowly as it continues to settle. Sulfur dioxide (SO2) emission rates are at background levels. Summit and Northeast Rift Zone inflation is slowing. For Mauna Loa monitoring data, see: usgs.gov/volcanoes/mauna-loa.
Kīlauea is not erupting. Its USGS Volcano Alert level is at ADVISORY. Kīlauea updates are issued weekly on Tuesdays.
Lava supply to the Halema'uma'u lava lake in Hawai'i Volcanoes National Park ceased on December 9. Sulfur dioxide emission rates have decreased to near pre-eruption background levels and were last measured at approximately 200 tonnes per day (t/d) on Dec. 14. Seismicity is elevated but stable, with few earthquakes. Over the past week, summit tiltmeters recorded several deflation-inflation (DI) events. For Kīlauea monitoring data, see usgs.gov/volcanoes/kilauea.
There was one earthquake with 3 or more felt reports in the Hawaiian Islands during the past week: a M3.3 event 11 km (7 mi) E of Pāhala at 34 km (21 mi) depth on Dec. 14 at 11:45 a.m. HST.
HVO continues to closely monitor the ongoing eruptions at Kīlauea and Mauna Loa.
Visit HVO's website for past Volcano Watch articles, Kīlauea and Mauna Loa updates, volcano photos, maps, recent earthquake info, and more. Email questions to askHVO@usgs.gov.
