We further detail the temporal and spatial changes in earthquake rates and ground strain along the south flank induced by six major rift intrusions which occurred between December 1971 and January 1981. The seismic response of the south flank to individual rift intrusions is immediate; the increased rate of earthquake activity lasts from 1 to 4 weeks. Horizontal strain measurements indicate that compression of the south flank usually accompanies rift intrusions and eruptions. Emplacement of an intrusion at a depth greater than about 4 km, such as the June 1982 southwest rift intrusion, however, results in a slight extension of the subaerial portion of the south flank.</div><div class=\"u-margin-s-bottom\"><br data-mce-bogus=\"1\"></div><div class=\"u-margin-s-bottom\">Horizontal strain measurements along the south flank are used to locate the January 1983 east-rift intrusion, which resulted in eruptive activity. The intrusion is modeled as a vertical rectangular sheet with constant displacement perpendicular to the plane of the sheet. This model suggests that the intrusive body that compressed the south flank in January 1983 extended from the surface to about 2.4 km depth, and was aligned along a strike of N66°E. The intrusion is approximately 11 km in length, extended beyond the January 1983 eruptive fissures, which are 8 km in length and is contained within the 14-km-long region of shallow rift earthquakes.</div>","language":"English","publisher":"Elsevier","doi":"10.1016/0040-1951(86)90200-3","issn":"00401951","usgsCitation":"Dvorak, J., Okamura, A., English, T., Koyanagi, R.Y., Nakata, J.S., Sako, M., Tanigawa, W., and Yamashita, K., 1986, Mechanical response of the south flank of Kilauea volcano, Hawaii, to intrusive events along the rift systems: Tectonophysics, v. 124, no. 3-4, p. 193-209, https://doi.org/10.1016/0040-1951(86)90200-3.","productDescription":"17 p.","startPage":"193","endPage":"209","costCenters":[],"links":[{"id":224019,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawaii","otherGeospatial":"Kilauea volcano","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -155.46126003973447,\n              19.32313934378122\n            ],\n            [\n              -155.46126003973447,\n              19.19866425187726\n            ],\n            [\n              -155.2306109623595,\n              19.19866425187726\n            ],\n            [\n              -155.2306109623595,\n              19.32313934378122\n            ],\n            [\n              -155.46126003973447,\n              19.32313934378122\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"124","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a535ce4b0c8380cd6ca13","contributors":{"authors":[{"text":"Dvorak, J.J.","contributorId":52597,"corporation":false,"usgs":true,"family":"Dvorak","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":370089,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Okamura, A.T.","contributorId":70400,"corporation":false,"usgs":true,"family":"Okamura","given":"A.T.","email":"","affiliations":[],"preferred":false,"id":370092,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"English, T.T.","contributorId":49799,"corporation":false,"usgs":true,"family":"English","given":"T.T.","email":"","affiliations":[],"preferred":false,"id":370087,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Koyanagi, R.

Comparison of these samples with previous gas samples shows that the composition of volatiles in the magma has remained constant over the 3-year course of this episodic east rift eruption of Kilauea volcano. The uniformly carbon depleted nature of these gases is consistent with previous suggestions that all east rift eruptive magmas degas during prior storage in the shallow summit reservoir of Kilauea.

After the reawakening and catastrophic eruption of Mount St. Helens in 1980, the program was substantially expanded as the government and general public became aware of the potential for eruptions and associated hazards within the conterminous United States.

Johnston Cascades Volcano Observatory was established in Vancouver, Washington, to systematically monitor the continuing activity of Mount St. Helens, and to acquire baseline data for monitoring the other, presently quiescent, but potentially dangerous Cascade volcanoes in the Pacific Northwest.

In order to become better prepared for possible future hazards associated with such historically unpecedented events, detailed studies of these, and similar, large volcanic systems should be intensified to gain better insight into caldera-forming processes and to recognize, if possible, the precursors of caldera-forming eruptions.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0264-3707(85)90045-6","issn":"02643707","usgsCitation":"Tilling, R., and Bailey, R., 1985, Volcano hazards program in the United States: Journal of Geodynamics, v. 3, no. 3-4, p. 425-446, https://doi.org/10.1016/0264-3707(85)90045-6.","productDescription":"22 p.","startPage":"425","endPage":"446","numberOfPages":"22","costCenters":[],"links":[{"id":487131,"rank":2,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1016/0264-3707(85)90045-6","text":"External Repository"},{"id":219195,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc334e4b08c986b32affc","contributors":{"authors":[{"text":"Tilling, R.I. 0000-0003-4263-7221","orcid":"https://orcid.org/0000-0003-4263-7221","contributorId":98311,"corporation":false,"usgs":true,"family":"Tilling","given":"R.I.","affiliations":[],"preferred":false,"id":357508,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bailey, R.

Each eruptive phase was accompanied by subsidence of the summit region and followed by reinflation of the summit to approximately the same level before renewal of eruptive activity. The cyclic summit tilt pattern and the absence of measurable tilt changes near the eruptive site suggest that conditions in the summit region controlled the timing of the last six eruptive phases. The rate of summit subsidence progressively increased from one eruptive phase to the next during the last six phases; the amplitude of harmonic tremor increased during the last four phases. The increases in subsidence rate and in tremor amplitude suggest that frequent periods of magma movement have reduced the flow resistance of the conduit system between the summit and the rift zone. ?? 1985.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Volcanology and Geothermal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"03770273","usgsCitation":"Dvorak, J., and Okamura, A., 1985, Variations in tilt rate and harmonic tremor amplitude during the January-August 1983 east rift eruptions of Kilauea Volcano, Hawaii: Journal of Volcanology and Geothermal Research, v. 25, no. 3-4, p. 249-258.","startPage":"249","endPage":"258","numberOfPages":"10","costCenters":[],"links":[{"id":222624,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc191e4b08c986b32a656","contributors":{"authors":[{"text":"Dvorak, J.J.","contributorId":52597,"corporation":false,"usgs":true,"family":"Dvorak","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":364740,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Okamura, A.T.","contributorId":70400,"corporation":false,"usgs":true,"family":"Okamura","given":"A.T.","email":"","affiliations":[],"preferred":false,"id":364741,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

HT is generally poorer in CaO and Al</span><sub>2</sub><span>O</span><sub>3</sub><span>&nbsp;and much richer in total iron and TiO</span><sub>2</sub><span>&nbsp;compared with MORB having the same MgO content.

MORB is generated by partial melting of a trace element depleted Iherzolite source leaving a residual assemblage dominated by olivine and orthopyroxene. The percentage of partial melting for a primary magma containing 15% MgO is calculated to be 35–42% in a source mantle having a heavy rare earth content of 3×chondrite and 33–35% MgO. HT, represented by Kilauea tholeiite, is generated by partial melting of a mixture of unmelted and residual mantle for MORB which has been modified by metasomatic addition of a nephelinitic fluid, amphibole, and minor amounts of apatite and Fe‐bearing phases such as sulfide and magnetite/ilmenite. This model yields a picritic magma in equilbrium with magnesian dunite at high (&gt;40%) degrees of partial melting. The source also has 35% MgO before partial melting. Melting in both systems in polyvariant and not controlled by lower‐temperature invariant equilibria. The low‐velocity zone is considered to be the source of metasomatic fluids that are driven upward into the lowermost lithosphere in response to a thermal plume. Picritic primary magmas are produced by shear melting, localized in the zone of thinned and metasomatized lithosphere beneath Hawaii. Melt extraction is rapid and episodic at intervals of months to decades; magma is not stored in the mantle but passes upward to a plexus of storage reservoirs located 2–6 km beneath the surface of Kilauea. Kilauea primary magmas fractionate olivine during upward transport to reach bulk compositions of 13–14% MgO in storage. Different magma batches erupted to the surface, distinguished by different major and minor element compositons compared at similar MgO content, represent combinations of differing degrees of metasomatic enrichment, differing degrees of partial melting, and some effects of premelting mantle heterogeneity.</span></p>","language":"English","publisher":"AGU","doi":"10.1029/JB089iB05p03233","usgsCitation":"Wright, T., 1984, Origin of Hawaiian tholeiite: A metasomatic model: Journal of Geophysical Research B: Solid Earth, v. 89, no. 5, p. 3233-3252, https://doi.org/10.1029/JB089iB05p03233.","productDescription":"20 p.","startPage":"3233","endPage":"3252","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":370418,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawaii","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -160.48828125,\n              21.6778482933475\n            ],\n            [\n              -156.181640625,\n              18.271086109608877\n            ],\n            [\n              -154.0283203125,\n              19.68397023588844\n            ],\n            [\n              -159.14794921875,\n              22.958393318086348\n            ],\n            [\n              -160.48828125,\n              21.6778482933475\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"89","issue":"5","noUsgsAuthors":false,"publicationDate":"2012-09-20","publicationStatus":"PW","contributors":{"authors":[{"text":"Wright, Thomas L. twright@usgs.gov","contributorId":3890,"corporation":false,"usgs":true,"family":"Wright","given":"Thomas L.","email":"twright@usgs.gov","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":777861,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Analyses of some glassy rims indicate that the outer millimeter of the glass can undergo lowtemperature hydration by hydroxyl groups having δD values as low as −100.</p><p>δD values vary with H<sub>2</sub>O contents of subaerial transitional basalts from Molokai, Hawaii, and subaerial alkali basalts from the Society Islands, indicating that the primary δD values were similar to those of submarine lavas.</p><p>Extrapolations to possible unaltered δD values and H<sub>2</sub>O contents indicate that the primary δD values of most thoteiite and alkali basalts are near −80 ± 5: the weight percentages of water are variable, 0.15–0.35 for MOR tholeiites, about 0.25 for Hawaiian tholeiites, and up to 1.1 for alkali basalts. The primary δD values of −80 for most basalts are comparable to those measured for deep-seated phlogopites. These results indicate that hydrogen, in marked contrast to other elements such as Sr, Nd, Pb, and O, has a uniform isotopic composition in the mantle. This uniformity is best explained by the presence of a homogeneous reservoir of hydrogen that has existed in the mantle since the very early history of the Earth.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0016-7037(84)90392-2","issn":"00167037","usgsCitation":"Kyser, T., and O’Neil, J.R., 1984, Hydrogen isotope systematics of submarine basalts: Geochimica et Cosmochimica Acta, v. 48, no. 10, p. 2123-2133, https://doi.org/10.1016/0016-7037(84)90392-2.","productDescription":"11 p.","startPage":"2123","endPage":"2133","numberOfPages":"11","costCenters":[],"links":[{"id":220112,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"48","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a334ee4b0c8380cd5eec7","contributors":{"authors":[{"text":"Kyser, T.K.","contributorId":25585,"corporation":false,"usgs":true,"family":"Kyser","given":"T.K.","email":"","affiliations":[],"preferred":false,"id":366733,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O’Neil, J.
