Mauna kea what type of volcano




















It is usually interpreted to mean White Mountain because of the snow that is often visible at the Mauna Kea summit. Mauna Kea is sacred in Hawaiian culture. If you are planning a trip to the top, prepare for cold. Even when there isn't snow on the mountain the temperature can be 40 or more degrees cooler than at the beach. Know before you go. The road to the top is closed often due to snow and high winds.

To check current conditions visit the Mauna Kea Weather Center. A short trail of approximately. Views up here are spectacular. Be prepared for high winds and cold temperatures.

A somewhat more challenging option is a hike to Lake Waiau located at an elevation of 13, feet 3, meters. The easiest route for hiking to Lake Waiau begins approximately 2 miles below the Mauna Kea summit. Hikers should be in good physical condition, have adequate hiking shoes no sandals and wear warm clothing.

From the ridge above the lake it is possible to see some of the telescopes at the Mauna Kea Observatory. The Mauna Kea Observatory is second to none, with more than a dozen giant telescopes focusing on deep space.

If the altitude doesn't take your breath away, the view certainly will! The air at this elevation is clean and crisp, making for impressive views in all directions. The image of the Mauna Kea Observatory in the photo below was taken from high on the slopes of Mauna Loa , about 20 miles south of the Mauna Kea summit. The eruption of these viscous postshield lavas from high-elevation vents formed a thick cap and contributed to the steepening of Manua Kea's slopes, which are twice as steep as the upper flanks of Mauna Loa.

The average lava supply during the Hamakua Volcanics was about 0. Geologic map of Mauna Kea, showing generalized distribution of lava flows, cinder cones, and glacial deposits of the Laupahoehoe Volcanics. These cones and flows create much of the topographic irregularities that make the upper slopes and summit of Mauna Kea in contrast with the much smoother slopes of the Mauna Loa shield.

It is likely that these eruptions occurred as sporadic clusters of activity, the most recent between 6, and 4, years ago. Laupahoehoe eruptions produced large volumes of tephra that fell beyond the cinder cones.

The ash is a dominant component of the surficial geology that blanket parts of Mauna Kea's flanks. Scientists estimate that about 25 km 3 of lava erupted during the Laupahoehoe activity, giving an average lava-supply rate of about 0. Skip to main content. Search Search. Mauna Kea. Geology and History. Such an eruption happened about 1 km 0. There is no reason to fear such an eruption.

It would not threaten human life, provided due care were taken, though it could prove devastating to property and infrastructure, particularly if a lava flow traveled to the Hamakua coast or the Waimea area. Mauna Kea's seismicity. The seismicity detected beneath Mauna Kea has been characterized as "infrequent and sparse.

Island-wide instrumentation allowed excellent location data for the local seismicity figure 8. HVO reported that, several times each year, earthquakes from Mauna Kea cause shaking that is noted by local populations - especially the operators of the Mauna Kea astronomical observatory, who rely on stable instrumentation in order to make precise observations.

Reports of felt earthquakes from Mauna Kea correlated with magnitude 2. Elevated seismicity during October-December resulted in 30 felt earthquakes. Approximately people reported the M 4. HVO reported that, like many of Mauna Kea's earthquakes, these earthquakes were "most likely caused by structural adjustments within the Earth's crust due to the heavy load of Mauna Kea.

Earthquake swarms at Mauna Kea. HVO reported that earthquake swarms occasionally occur at Mauna Kea. Lake Waiau recedes. Lake Waiau has likely persisted due to the once-glassy cinders and bombs that have weathered to smectite with zeolites within the void spaces. These alteration products may serve as a weak cement between the pyroclasts and reduce the permeability of the cinder cone's base.

Sporadic winter storms have provided most, if not all, of the water captured in this considerably arid region Patrick and Delparte, Contributions from permafrost were also proposed by Woodcock , but the presence of permafrost has not been confirmed near Lake Waiau. In the recent past, the lake was known to overflow through the Pohakuloa Gulch when water levels exceeded the rim as recently as February Ehlmann and others, Researchers have determined that Lake Waiau is sensitive to precipitation levels Woodcock, and that ongoing drought conditions could be driving the lake's change Patrick and Delparte, Based on the National Drought Mitigation Center's data, since , and notably in March , precipitation has been sparse at the summit of Mauna Kea.

In December , scientists visited the lake and observed an unprecedented sight figure Lake Waiau measured a mere m 2 and was roughly cm deep Patrick and Delparte, While the lake size was known to fluctuate over time, this dramatic reduction has caused concern, given the possibility of losing a specialized ecosystem as well as a prominent feature of Hawaiian ethnogeography.

Mauna Kea's summit is considered "one of the most sacred spots in the Hawaiian Islands. Archaeological sites near the summit attest to its prolonged spiritual importance Patrick and Delparte, As of May , strong winter rains had partially restored the lake, providing stronger evidence that the multi-year shrinkage was due to the ongoing drought as opposed to changes in the volcanic system. A note regarding the name Mauna Kea. The popular translation of the Hawaiian name Mauna Kea is frequently "White Mountain," however, significant discussions have focused on the source of the name.

There has been growing consensus that Mauna Kea is a shortened form of Mauna a Wakea, which refers to the sky father Wakea. A-AD-6 1 which included potential cultural impacts on the island by expanding State Routes and , "The mountain is the sacred child of Wakea, and it is the source for the land. The mountains and land were genealogically connected to native Hawaiians through the original ancestor, Wakea [sky father] and Papa [earth mother].

Ethnographic research conducted prior to and released in the impact statement concluded that the summit area of Mauna Kea was eligible for the National Register of Historic Places due to traditional cultural property.

A note regarding Hawaiian names and nomenclature. As previously noted in other Bulletin reports, according to Runyon , "The U. Board on Geographic Names BGN is responsible for establishing and maintaining uniform geographical name usage throughout all departments and agencies of the United States government.

As such, the Board collects and promulgates every name that is considered official for Federal use. The few exceptions included the Spanish tilde and the French accent marks, but otherwise the special characters found in indigenous names were always dropped. In more recent years, however, the BGN has amended its policy to permit the inclusion of such marks, thus more accurately reflecting the true representation of the native language.

An example of this has been the addition of the glottal stop okina and macron kahako to placenames of Hawaiian origin, which prior to had always been omitted. It remains a technological challenge, but a goal. References: Clague, D. Part I. Geologic evolution, chap.
