Life in Mauna Kea's Alpine Desert
Life in Mauna Kea’s by Mike Richardson Alpine Desert Lycosa wolf spiders, a centipede that preys on moribund insects that are blown to the summit, and the unique, flightless wekiu bug. A candidate for federal listing as an endangered species, the wekiu bug was first discovered in 1979 by entomologists on Pu‘u Wekiu, the summit cinder cone. “Wekiu” is Hawaiian for “topmost” or “summit.” The wekiu bug belongs to the family Lygaeidae within the order of insects known as Heteroptera (true bugs). Most of the 26 endemic Hawaiian Nysius species use a tube-like beak to feed on native plant seed heads, but the wekiu bug uses its beak to suck the hemolymph (blood) from other insects. High above the sunny beaches, rocky coastline, Excluding its close relative Nysius a‘a on the nearby Mauna Loa, the wekiu bug and lush, tropical forests of the Big Island of Hawai‘i differs from all the world’s 106 Nysius lies a unique environment unknown even to many species in its predatory habits and unusual physical characteristics.

SERIES n A 5 o The world-famed volcano of Kilauea, eight miles in circumference An Appreciation of the Hawaii National Park By E. M. NEWMAN, Traveler and Lecturer Written Especially for the United States Railroad Administration §HE FIRES of a visible inferno burning in the midst of an earthly paradise is a striking con trast, afforded only in the Hawaii National Park. It is a combination of all that is terrify ing and all that is beautiful, a blending of the awful with the magnificent. Lava-flows of centuries are piled high about a living volcano, which is set like a ruby in an emer ald bower of tropical grandeur. Picture a perfect May day, when glorious sunshine and smiling nature combine to make the heart glad; then multiply that day by three hundred and sixty-five and the result is the climate of Hawaii. Add to this the sweet odors, the luscious fruits, the luxuriant verdure, the flowers and colorful beauty of the tropics, and the Hawaii National Park becomes a dreamland that lingers in one's memory as long as memory survives. Pa ae three To the American People: Uncle Sam asks you to be his guest. He has prepared for you the choice places of this continent—places of grandeur, beauty and of wonder. He has built roads through the deep-cut canyons and beside happy streams, which will carry you into these places in comfort, and has provided lodgings and food in the most distant and inaccessible places that you might enjoy yourself and realize as little as possible the rigors of the pioneer traveler's life. -

UH will prepare the EIS in accordance with the provisions and requirements of Hawai'i Revised Statutes (HRS) Chapter 343. Pursuant to HRS Chapter 343-S(c), an Agency Publication Form and Environmental Impact Statement Preparation Notice (EISPN) are attached. The EISPN includes a description of the requested land authorization and a brief discussion of the kinds of potential environmental impacts which will be analyzed in the forthcoming EIS. In accordance with Hawai'i Administrative Rules Chapter 11-200, we respectfully request that you publish this notice in the next available edition of The Environmental Notice for the public to submit comments to UH during the statutory 30-day public consultation period. If you have any further questions about this letter or its attachments, please contact Stephanie Nagata, Director, Office of Mauna Kea Management, at (808) 933-0734. -

Geology, Geochemistry and Earthquake History of Lō`Ihi Seamount, Hawai`I

Becker1 1Department of Geology and Geophysics, University of Hawai`i, Honolulu, HI, USA 2U.S.G.S., Alaska Volcano Observatory, Anchorage, AK, USA 3Department of Oceanography, University of Hawai`i, Honolulu, HI, USA 4Department of Chemistry, Woods Hole Oceanographic Institution, Woods Hole, MA, USA *Corresponding author: Tel.: 001-808-956-6641, FAX: 001-808-956-5521; email: [email protected] Key words: Loihi, seamount, Hawaii, petrology, geochemistry, earthquakes Abstract A half century of investigations are summarized here on the youngest Hawaiian volcano, Lō`ihi Seamount. It was discovered in 1952 following an earthquake swarm. Surveying in 1954 determined it has an elongate shape, which is the meaning of its Hawaiian name. Lō`ihi was mostly forgotten until two earthquake swarms in the 1970’s led to a dredging expedition in 1978, which recovered young lavas. This led to numerous expeditions to investigate the geology, geophysics, and geochemistry of this active volcano. Geophysical monitoring, including a real- time submarine observatory that continuously monitored Lō`ihi’s seismic activity for three months, captured some of the volcano’s earthquake swarms. The 1996 swarm, the largest recorded in Hawai`i, was preceded by at least one eruption and accompanied by the formation of a ~300-m deep pit crater, renewing interest in this submarine volcano. Seismic and petrologic data indicate that magma was stored in a ~8-9 km deep reservoir prior to the 1996 eruption. -
