Last Saturday, the National Park of American Samoa participated in this year’s Family Day to culminate Coastweek events alongside with outer local government agencies, organizations, and vendors.
Chief Michael and Park Ranger Sam manned the national park booth that entertained kids (and adults) who wanted to be a Junior Ranger. It was fun interacting with the kids as they tell stories of how they protect and preserve our island’s natural resources. They were also able to learn about the national park throughout the Junior Ranger Activity book they had to complete to earn a unique badge and certificate.
In all, we inducted and awarded over 50 new Junior Ranger stewards for this islands preservation and conservation! Fa’afetai to all who dropped by to say “hi” and learned something about the things we do.
Three student artists from Maui Waena Intermediate School and one student from Kihei Charter School have won the recent Nēnē Awareness Day Logo Contest.
Heather Angel Jane Ramos from Maui Waena placed first with “Don’t Destroy the Nēnē’s Home.” Brissa Mae Natividad, also of Maui Waena, won second place with her artwork, “Clean Up Your Mess to Save the Nēnē’s Nest.” Another Maui Waena student, Cherish Ramento, won third place for “Watch Out and Let Them Cross.” A student from Kihei Charter School, Hina Claerbout, tied for third place with “Let the Population of the Nēnē Take Flight.”
Each student will receive prizes provided by Hawai`i Pacific Parks Association, a non-profit partner of Haleakalā National Park.
Two middle schools participated in the contest. All submitted artwork will be displayed at the Headquarters Visitor Center starting on September 26, which is Nēnē Awareness Day. The public can also view all entries in the park’s booth at the Maui County Fair. Artists may pick up their work and prizes either at the park or at the Maui County Fair. The winning entries will also be posted on the park’s Facebook page.

The following is this week’s edition of “Volcano Watch” from the USGS Hawaiian Volcano Observatory:
Much scientific study has been done to determine what types of eruptions produce long lava flows. In the 1970s, a very simple idea seemed to guide future work—the length of a lava flow is limited by either the supply of lava or by how well the lava is thermally insulated during its transport to the flow front.
Supply-limited lava flows are those that stop advancing when the vent closes down or eruptive activity moves to another location, cutting off the lava supply. This is a fairly simply idea that’s easy to visualize—the lava flow lasts as long as its vent erupts. The best examples of supply-limited lava flows in Hawaiʻi are from Mauna Loa. Lava flows that advanced on Hilo in 1855, 1881, and 1984, eventually stalled above the town as their respective eruptions waned and the supply of lava to the flow stopped.
But what about vents that keep erupting, like Puʻu ʻŌʻō? Are they capable of producing lava flows that get longer and longer? It depends on how well the lava is thermally insulated as it’s transported through the flow’s tube system.
Solidified lava is an excellent thermal insulator. As lava forms a surface crust, the flow progressively insulates its internal plumbing and eventually forms a lava tube system. That tube system transports lava from the vent to its leading edge, and, as long as the lava doesn’t lose too much heat, the flow will continue to advance.
Over the past three decades, lava flows erupted at Puʻu ʻŌʻō have formed some robust tube systems that have delivered lava to ocean entries for months—or up to a few years—before changes at the vent caused the tube to be abandoned. If those flows hadn’t encountered a coastline, the lava might have continued to advance for a much greater distance.
The Kazumura lava tube system is a particularly good example of how far lava can travel. The tube is within the ʻAilāʻau lava flow field that erupted from vents near the summit of Kīlauea 550–600 years ago and sent flows down the northeast flank of the volcano and into the sea. Kaloli Point was built by an ocean entry during this eruption, which is estimated to have lasted more than 50 years. The Kazumura lava tube system is more than 65 km (40 miles) long, and the part of it not filled with lava is now listed as the longest lava tube cave in the world.
Within this context, why did the June 27th lava flow slow as it approached Pāhoa? HVO scientists noted that the lava flow began to slow considerably as the summit of Kīlauea began to deflate on Thursday, September 18. Such deflations have caused decreases in eruptive output at Puʻu ʻŌʻō in the past, and that could be the case with the current flow as well.
Another possibility for the stalled flow front is that the tube system feeding the June 27th lava flow could be approaching its limits in terms of efficiently insulating the lava moving through it. Based on HVO observations during our September 24 overflight, the lava tube system seems fairly robust from the vent at Puʻu ʻŌʻō to just before the point where lava first flowed into a crack. The exact condition of the lava tube within the crack is unknown because we can’t see into it, but it seems to also be robust.
However, the nature of the tube system from the point at which the lava flow exits the ground crack system near Kaohe Homesteads and heads northeast toward Pāhoa is not yet clear. Although lava has traveled beneath this section of the flow to the flow front since early September, a lava tube system is not yet evident.
The June 27th lava flow is now longer than any other flow formed during the ongoing eruption of Puʻu ʻŌʻō. While the evidence favors a decrease in eruptive output as the cause of the current slow-down, careful study is still needed. If and how a lava tube develops within the distal portion of the June 27th lava flow is important to understanding just how far it, and other pāhoehoe flows like it, is capable of advancing.
It’s important to note that although the flow front has slowed, the June 27th lava flow remains active. Puna residents are encouraged to stay informed about the flow’s status and progress through daily updates posted on HVO and Hawaiʻi County Civil Defense websites (http://hvo.wr.usgs.gov and http://www.hawaiicounty.gov/active-alerts/).
Yesterday, the National Park of American Samoa had the pleasure to spend a little quality time with some of the crews from Hōkūle’a and Hikinalia as part of their voyage here in American Samoa.
Park Ranger Pua brought them to the different spots leading to the national park as he integrated similarities and connections between Samoan and Hawaiian stories, cultures, and beliefs. The crews enjoyed a quick dip at Pola Island at the end of the program as they sit back and relax after a long productive day.

Cultural Resource Management (CRM) Specialists at Hawai’i Volcanoes National Park recently took a day to share their knowledge and expertise with a group of college interns from the Wahi Kūpuna Internship Program (WKIP). The WKIP program was developed in 2010 in partnership with Kamehameha Schools and is run by the Kumupa’a Cultural Resource Consultants, LLC and Huliauapa’a, a non-profit organization. The primary goal of the internship is to increase the number of Hawaiians and kama’āina in the cultural resource management field through cultural mentoring, professional development, education, and applied field experiences. The internship exposes the students to the many different career paths within CRM and enables them to receive college credit for the course at University of Hawai‘i at Hilo or Hawai‘i Community College.
The five-week program focused on the wahi pana (sacred places) of Ka’ū, with many field trips and site visits, including a trip to Hawai’i Volcanoes National Park. HAVO CRM staff were excited to share their knowledge with the students and expose them to the many different facets of cultural resource stewardship.
Park archeologists Summer Roper and Kalena Blakemore led the students on a tour of the largest petroglyph field in Hawai’i, Pu‘uloa Petroglyphs, located within the national park. They shared the rich history of the place and also discussed what it is like to be a park archeologist. This work includes the numerous tasks that it takes to protect, preserve, record and learn from the hundreds of archeological sites located within the park.
After the petroglyphs, the students then met the park’s historic landscape architect and historic preservation specialist, Larry Frey, at the historic 1932 Administration building, located next to the Volcano House. The 1932 Administration building is the future home of the park’s cultural museum and curatorial center. Larry took the students on a tour of the building and the surrounding grounds and discussed in detail the restoration project that will be undertaken in order to return the historic structure and landscape to its former glory. Historic preservation poses many challenges when trying to keep the historic fabric of a building intact, yet at the same time meet modern building codes and, in this case, museum standards. This was a perfect example of historic preservation work in progress for the students to learn from observe. Soon they will be able to return and see the finished product when the museum opens to the public.
The next stop for the students was a trip down into the basement of the Headquarters building to see the archives and some of the park’s museum and art collection. Park archivist Emily Pronovost and park museum technician Kristi Ausfresser shared examples of the park’s artifacts, original art work, archival documents, historic photos, and historic books that are housed in the park museum collection. They discussed their job of taking care of the irreplaceable objects, some of the challenges they face, and what their jobs entail: protecting items from damage by maintaining climate-controlled rooms, ordering special containers, managing insect infestation, and guarding against flooding or any other environmental concerns that can deteriorate or destroy the fragile museum objects.
The field trip was capped off with a trip to the historic 1877 Volcano House (Volcano Art Center) and to the Jaggar Museum. The students enjoyed their day at the park and CRM staff were able to contribute to their overall understanding of the field of cultural resource management, share their knowledge and passion for what they do, and possibly help inspire a new generation of cultural resource stewards.
