Mathematical and Numerical Models of Lava Dome Dynamics
, 2022 Dome-building eruptions may vary from unthreatening effusion to highly unpredictable and hazardous activity including collapse of domes and associated pyroclastic flow hazards. We analyse the influence of the thermal cooling and the crystal content growth on the lava dome morphology at Volcán de Colima in Mexico during a long dome-building episode ...

Thermally induced convective circulation and precipitation over an isolated volcano [PDF]
, 2016 Intense rainfall over active volcanoes is known to trigger dangerous volcanic hazards, from remobilizing loose volcanic surface material into lahars or mudflows to initiating explosive activity including pyroclastic flows at certain dome-forming ...

Remote Sensing, 2021 Lunar volcanic domes are essential windows into the local magmatic activities on the Moon. Classification of domes is a useful way to figure out the relationship between dome appearances and formation processes.

Lava dome collapse causes pyroclastic flows
Eos, Transactions American Geophysical Union, 1993 Growth of lava domes is common at many volcanos, especially those around the Pacific rim, and the pyroclastic flows associated with these domes constitute one of the most serious of all volcanic hazards. Over thirty‐five scientists from Japanese and U.S. universities and government agencies gathered in Palo Alto, Calif., from March 8–12, to discuss and

The Leaning Puy de Dôme (Auvergne, France) tilted by shallow intrusions
Volcanica, 2019 Monogenetic lava domes are a special type of volcanic structure, prone to mass wasting and explosive eruptions. The iconic Puy de Dôme (Chaîne des Puys, Auvergne)—which gave its name to ‘dome’ landforms—is asymmetric, with one side steeper than the other.

Frontiers in Earth Science, 2019 Lava dome collapses pose a hazard to surrounding populations, but equally represent important processes for deciphering the eruptive history of a volcano.

Basaltic lava domes, lava lakes, and volcanic segmentation on the southern East Pacific Rise [PDF]
Journal of Geophysical Research: Solid Earth, 2000 Meter‐scale DSL‐120 sonar mapping and coregistered Argo II photographic observations reveal changes in eruptive style that closely follow the third‐order structural segmentation of the ridge axis on the southern East Pacific Rise, 17°11′–18°37′S. Near segment ends we observe abundant basaltic lava domes which average 20 m in height and 200 m in basal ...

Tremor and its duration‐amplitude distribution at Popocatépetl volcano, Mexico
Geophysical Research Letters, 2016 The duration‐amplitude distribution was calculated for the tremor observed at Popocatépetl volcano during episodes of activity in 2000 and 2012–2014. An exponential function was used to obtain a good fit for the duration‐amplitude distribution, and the ...

Fault textures in volcanic conduits: evidence for seismic trigger mechanisms during silicic eruptions. [PDF]
, 2005 It is proposed that fault textures in two dissected rhyolitic conduits in Iceland preserve evidence for shallow seismogenic faulting within rising magma during the emplacement of highly viscous lava flows. Detailed field and petrographic analysis of such

Re-identification of c. 15 700 cal yr BP tephra bed at Kaipo Bog, eastern North Island: implications for dispersal of Rotorua and Puketarata tephra beds. [PDF]
, 2003 A 10 mm thick, c. 15 700 calendar yr BP (c. 13 100 14C yr BP) rhyolitic tephra bed in the well-studied montane Kaipo Bog sequence of eastern North Island was previously correlated with Maroa-derived Puketarata Tephra.
