The south flank of Kilauea volcano has experienced two large [magnitude (M) 7.2 and M 6.1] earthquakes in the past two decades. Global Positioning System measurements conducted between 1990 and 1993 reveal seaward displacements of Kilauea's central south flank at rates of up to about 10 centimeters per year. In contrast, the northern side of the volcano and the distal ends of the south flank did not displace significantly. The observations can be explained by slip on a low-angle fault beneath… Expand
High magma storage rates before the 1983 eruption of kilauea, hawaii
Three-dimensional numerical modeling shows that this deformation is consistent with the dilation of a dike within Kilauea's rift zones coupled with creep over a narrow area of a low-angle fault beneath the south flank. Expand
Structural variability along the submarine south flank of Kilauea volcano, Hawai'i, from a multichannel seismic reflection survey
Recent analysis of marine multichannel seismic reflection data collected across the south flank of Kilauea volcano, Hawaii has confirmed that the distal flank records significant accretion andExpand
Sudden aseismic fault slip on the south flank of Kilauea volcano
It is reported that, in early November 2000, this network recorded transient southeastward displacements, which is interpreted as an episode of aseismic fault slip, demonstrating that continuously recording geodetic networks can detect accelerating slip, potentially leading to warnings of volcanic flank collapse.

Volcanic spreading at Kilauea, 1976–1996
The rift system traversing about 80 km of the subaerial surface of Kilauea volcano has extended continuously since the M 7.2 flank earthquake of November 1975. Widening across the summit has amountedExpand
Mantle Fault Zone Beneath Kilauea Volcano, Hawaii
Relocations and focal mechanism analyses of deep earthquakes (≥13 kilometers) at Kilauea volcano demonstrate that seismicity is focused on an active fault zone at 30-kilometer depth, with seawardExpand
Rapid deformation of Kilauea Volcano: Global Positioning System measurements between 1990 and 1996
Campaign Global Positioning System (GPS) measurements from 1990 to 1996 are used to calculate surface displacement rates on Kilauea Volcano, Hawaii. The GPS data show that the south flank of theExpand
Slope failure and volcanic spreading along the submarine south flank of Kilauea volcano, Hawaii
[1] New multichannel reflection data and high-resolution bathymetry over the submarine slopes of Kilauea volcano provide evidence for current and prior landsliding, suggesting a dynamic interplayExpand
Focused seismicity triggered by flank instability on Kīlauea's Southwest Rift Zone
Abstract Swarms of earthquakes at the head of the Southwest Rift Zone on Kīlauea Volcano, Hawaiʻi, reveal an interaction of normal and strike-slip faulting associated with movement of Kīlauea's southExpand
Faulting in the South Flank of Kilauea Volcano, Hawai'i
Abstract Models developed to explain the deformation of Kilauea volcano largely rely on seismic and geodetic data that cover only a short period of activity. Kilauea's active South Flank contains twoExpand
Stabilization of volcanic flanks by dike intrusion: an example from Kilauea
Abstract Dike propagation and dilation increases the compression of adjacent rocks. On volcanoes, especially oceanic shields, dikes are accordingly thought to be structurally destabilizing. AsExpand


An earthquake cycle along the south flank of Kilauea Volcano, Hawaii
The intrusion of magma that led to the beginning of the January 3, 1983, eruption along the middle east rift zone of Kilauea Volcano, Hawaii, resulted in widening of the rift zone and compression ofExpand
Deep Magma Body Beneath the Summit and Rift Zones of Kilauea Volcano, Hawaii
Kilauea's magmatic system is probably deeper and more extensive than previously thought; the summit and both rift zones may be underlain by a thick, near vertical dike-like magma system at a depth of 3 to 9 kilometers. Expand
Anatomy of a basaltic volcano
Kilauea volcano, in Hawaii, may be the best understood basaltic volcano in the world. Magma rises from a depth of 80 km or more and resides temporarily in near-surface reservoirs: eruption beginsExpand
A fault model for the 1989 Kilauea South Flank Earthquake from leveling and seismic data
The geometry of the fault that ruptured during the M6.1 south flank earthquake on Kilauea volcano in 1989 is determined from leveling data. The elastic dislocation, in a homogeneous elasticExpand
Flexure and seismicity beneath the south flank of Kilauea Volcano and tectonic implications
We present a refined model for the tectonic behavior of Kilauea volcano's south flank, including flexure calculations and microearthquake data supportive of the model. In our model the south flankExpand
The 1962 flank eruption of Kilauea volcano and structure of the east rift zone
On December 7–9, 1962, a small flank eruption occurred on the upper part of the east rift zone of Kilauea volcano. The six eruptive fissures, which show a right-offset en echelon pattern, extend moreExpand
Motion of Kilauea Volcano during sustained eruption from the Puu Oo and Kupaianaha Vents, 1983–1991
Kilauea erupted almost continuously from January 1983 through 1991. Although the summit began subsiding during the rift zone dike intrusion that initiated this eruption, remarkably steady groundExpand
The Mechanics and Three‐Dimensional Internal Structure of Active Magmatic Systems: Kilauea Volcano, Hawaii
Interpretation of abundant seismic data suggests that Kilauea's primary conduit within the upper mantle is concentrically zoned to about 34-km depth. This zoned structure is inferred to contain aExpand
The Kalapana earthquake of November 29, 1975: An intra-plate earthquake and its relation to geothermal processes☆
Abstract By use of teleseismic and local data, the P-wave source mechanism of the Kalapana, Hawaii, earthquake of November 29, 1975 was found to have a common strike of N64°E for the two nodalExpand
Growth and persistence of Hawaiian volcanic rift zones
Hawaiian volcanic rift zones are modeled by representing the rifts and adjacent volcano flanks as long ridges with the geometry of flattened triangular prisms. The intrusion of dikes along the axisExpand
