Mauna Loa volcano, Hawaii, deforms by a combination of shallow dike intrusions in the rift zones and earthquakes along the base of the volcano, but it is not known how the spreading is accommodated in the lower part of the volcanic edifice. We present evidence from interferometric synthetic aperture radar data for secular inflation of a dike-like magma body at intermediate depth in the southwest rift zone during 2002 to 2005. Magma accumulation occurred in a section of the rift zone that was… Expand
Coupling of Hawaiian volcanoes only during overpressure condition
[1] Mauna Loa and Kilauea volcanoes, Hawaii, are thought to be coupled by pore pressure diffusion through an asthenospheric melt layer. However, abundant observations of independent activity of theseExpand
Coupling at Mauna Loa and Kīlauea by stress transfer in an asthenospheric melt layer
Over the past decade, Kīlauea and Mauna Loa—adjacent volcanoes in Hawai‘i—have inflated and deflated in tandem, yet their shallow volcanic plumbing systems are separate. Numerical modelling of theExpand
Interaction of volcano-tectonic fault with magma storage, intrusion and flank instability: A thirty years study at Mt. Etna volcano
Abstract We investigated the relationship between the occurrence of earthquakes along the main volcano-tectonic structures and periods of volcanic unrest at Mt. Etna. We focused our study on theExpand
Stress interaction between magma accumulation and trapdoor faulting on Sierra Negra volcano, Galápagos
Abstract Understanding the state of stress within volcanoes and how it changes with active geophysical processes is important to assess when and where magma may propagate to the surface and initiateExpand
A mantle-driven surge in magma supply to Kīlauea Volcano during 2003–2007
The supply of magma to Kīlauea Volcano, Hawai‘i, was thought to have been steady over the past decades. Measurements of deformation, gas emissions, seismicity and lava composition and temperaturesExpand
Southward growth of Mauna Loa’s dike-like magma body driven by topographic stress
TLDR
Space-geodetic observations of a new period of inflation at Mauna Loa volcano, Hawaii, recorded an influx of 0.11 km3 of new magma into it’s dike-like magma body during 2014–2020, which is consistent with a slowly ascending dike propagating laterally when encountering a stress barrier and freezing its tip when magma influx waned.

Geodetical and seismological evidences of stress transfer between Mauna Loa and Kilauea
Different studies evidenced an anticorrelated pattern behavior the activity of Mauna Loa and Kilauea volcanoes. We quantitatively demonstrate the existence of this pattern by using DInSAR SBAS timeExpand
Anatomy of an active submarine volcano
Most of the magma erupted at mid-ocean ridges is stored in a mid-crustal melt lens that lies at the boundary between sheeted dikes and gabbros. Nevertheless, images of the magma pathways linking thisExpand
Anatomy of an unstable volcano from InSAR: Multiple processes affecting flank instability at Mt. Etna, 1994–2008
[1] Volcano deformation may occur under different conditions. To understand how a volcano deforms, as well as relations with magmatic activity, we studied Mt. Etna in detail using interferometricExpand

Abstract Volcano flank instability has been recognized at many volcanoes around the globe. Structural, morphological, geodetic and geophysical evidence supports the continuous deformation of theirExpand

Vulcanology: Interaction between Kilauea and Mauna Loa
TLDR
This remarkable observation suggests that there is a crustal-level interaction between the magma systems of Mauna Loa and Kilauea, reviving a century-old controversy over the relationship between these two volcanoes on the basis of differences in their lava chemistry and in their patterns of eruptive behaviour.
