FLIGHT OPERATIONS IN HAWAI'I VOLCANOES NATIONAL PARK for December include:
   December 9 between 6:30 a.m. and 8:30 a.m. for ungulate survey at Kahuku Unit between 4,000- and 6,000-ft. elevation.
    December 16, 18, and 19 for transport of crew and equipment for fence replacement on Maunaloa between 4,000- and 6,000-ft. elevation.
    December 17 from 7 a.m. to 11 a.m. for invasive tree control and mapping in the Kaʻū desert along the western park boundary between 1,200- and 1,900-ft. elevation.
    December 18 from 8 a.m. to 12 p.m. for fountain grass control and mapping along the western park boundary from sea level to 3,500-ft. elevation.
    USGS Hawaiian Volcano Observatory may conduct additional flight operations over Kīlauea and Maunaloa to assess volcanic activity and maintain instrumentation.
   "The park regrets any noise impact to residents and park visitors. Dates and times are subject to change based on aircraft availability and weather," says an HVNP statement. "Management of the park requires the use of aircraft to monitor and research volcanic activity, conduct search-and-rescue missions and law enforcement operations, support management of natural and cultural resources, and to maintain backcountry facilities."

HOW HAVE ERUPTIONS SHAPED HAWAI'I? is the title of this week's Volcano Watch, written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates. January is Volcano Awareness Month 2025, with a twist.
    USGS Hawaiian Volcano Observatory monitors the six currently active volcanoes in Hawai'i, but past eruptions have shaped all of the Hawaiian Islands. Join us in January 2025 for Volcano Awareness Month, an opportunity to learn about volcanic activity in Hawai'i over the past year and beyond, or—new for this upcoming edition—submit art or poetry recognizing Hawaii's volcanic history.
    From Lēʻahi (Diamond Head) on Oʻahu to the changing caldera at the summit of Kīlauea volcano on the Island of Hawaiʻi, our landscape is shaped by volcanic processes and events. 2024 has been another year of dynamic volcanic activity on the Island of Hawai'i, with Kīlauea eruptions occurring outside of Kaluapele (the summit caldera) for the first time since 2018. Multiple intrusions into the upper portions of the Southwest Rift Zone and East Rift Zone culminated in a one-day eruption southwest of the caldera on June 3, and an eruption in and near Nāpau Crater on the middle East Rift Zone from Sept. 15-20.

Volcano Awareness Month is organized each January by USGS Hawaiian Volcano Observatory, along with close partners at Hawai'i Volcanoes National Park, University of Hawai'i at Hilo, Hawai'i County Civil Defense Agency, and other organizations. During January 2025, HVO will host talks and guided walks around the Island of Hawaiʻi to share information on a range of volcano-related topics. Come learn about volcanic activity and earthquakes over the past year, discover the island's extensive history of past eruptions and earthquakes, or hear how we monitor, map, and study volcanoes in Hawai'i.
    Kīlauea Visitor Center auditorium will be closed this coming January, so instead of weekly After Dark in the Park presentations as in years past, HVO scientists will be doing talks and walks on Tuesdays in Hawai'i Volcanoes National Park. Join HVO staff as they discuss the network of instruments monitoring Hawaii's volcanoes on Jan. 7, describe Kīlauea's ever-evolving summit caldera on Jan. 14, walk into the Whitney Vault (built in 1912 to host volcano monitoring equipment) on Jan. 21, or explain Kīlauea's explosive past during a guided walk on Jan. 28.
    Additional guided hikes will take place on Saturdays in January. Learn about the 1868 eruption while walking the Puʻu o Lokuana trail in the Kahuku Unit of Hawaiʻi Volcanoes National Park on Jan. 4. Hike to Maunaiki in the Kaʻū Desert of Hawaiʻi Volcanoes National Park—which erupted in 1919–1920—on Jan. 18. On Jan. 25, trek the slopes of Hualālai to learn about unique trachyte deposits in Puʻuwaʻawaʻa Forest Reserve.
    Talks summarizing eruptive activity and earthquakes over the past year will take place at Cooper Center in Volcano village on Jan. 9, Pāhoa Public Library on Jan. 13, University of Hawaiʻi at Hilo on Jan. 15, and Kailua-Kona Public Library on Jan. 22.
     Learn the art and science of geologic mapping in Hawai'i during a talk at the Volcano Art Center in Volcano village on Jan. 16. This program will be repeated at the University of Hawaiʻi at Hilo campus on Jan. 29.
    Other programs include a talk story opportunity with HVO staff at the Nāʻālehu Public Library on January 8, a talk in Pāhala on January 27 about earthquakes happening deep beneath that region since 2019, and a Geology Department open house at the University of Hawaiʻi at Hilo on January 24.
    Whether you can join us at an in-person Volcano Awareness Month event in January 2025 or not, we invite you to enter a new art and poetry contest, open January 1–20. Submit a haiku poem or art in any medium (but no larger than 16x24 inches in size) that is related to volcanic landscapes or eruptions in Hawaii. Winners in several categories will be announced in a "Volcano Watch" article at the end of January, and a selection of entries will be on display at a scientific conference on caldera-forming eruptions (such as Kīlauea's in 2018) being hosted in Hilo in February 2025.
    We hope to see you at a Volcano Awareness Month event in January 2025 and look forward to the art and poetry submissions! Learn more about January 2025 Volcano Awareness Month events and the art/poetry contest on HVO's website, or email askHVO@usgs.gov

VOLCANO ACTIVITY UPDATES: Kīlauea is not erupting. Its USGS Volcano Alert level is ADVISORY. Over the past week, elevated earthquake rates beneath Kīlauea summit and upper East Rift Zone continued. About 130 earthquakes were located beneath the summit, and about 270 were located in the upper East Rift Zone. Earthquake rates beneath the middle East Rift Zone were more than double that of the previous week, with about 100 located events. Ground deformation rates in the summit region showed steady inflation over the past week, while ground deformation rates near the September 15-20 middle East Rift Zone eruption site have slowed. Future intrusive episodes and eruptions could occur with continued magma supply.
    Mauna Loa is not erupting. Its USGS Volcano Alert Level is at NORMAL.
    Six earthquakes were reported felt in the Hawaiian Islands during the past week: a M3.5 earthquake 23 km (14 mi) WNW of Maunaloa at 7 km (4 mi) depth on Dec. 3 at 1:53 p.m. HST, a M3.0 earthquake 16 km (9 mi) S of Volcano at 1 km (0 mi) depth on Dec. 3 at 1:17 a.m. HST, a M2.5 earthquake 8 km (4 mi) SSW of Honaunau-Napoopoo at 20 km (12 mi) depth on Dec. 2 at 7:04 a.m. HST, a M4.0 earthquake 17 km (10 mi) WNW of Volcano at 20 km (12 mi) depth on Nov. 30 at 8:40 a.m. HST, a M3.3 earthquake 13 km (8 mi) E of Pāhala at 28 km (17 mi) depth on Nov. 29 at 6:38 p.m. HST, and a M2.8 earthquake 19 km (11 mi) SE of Waimea at 22 km (14 mi) depth on Nov. 28 at 8:29 a.m. HST.
   HVO continues to closely monitor Kīlauea and Mauna Loa.
