Constraining Formation Hypotheses for Irregular Mare Patches on the Moon With Orbital Reflectance Spectra

open access: yesJournal of Geophysical Research: Planets, Volume 129, Issue 2, February 2024.
Abstract Irregular mare patches (IMPs) are enigmatic volcanic features on the Moon's surface, whose lack of cratering and crisp appearance imply they formed <100 Ma ago, ∼1 Ga after the expected turnoff of lunar volcanism. Multiple contrasting formation hypotheses have been put forth to explain their young appearance, including recent emplacement via ...

Large tectonic earthquakes induce sharp temporary decreases in seismic velocity in Volcán de Colima, Mexico [PDF]

open access: yes, 2014
International audienceWe used the ambient noise cross-correlation and stretching methods to calculate variations in seismic velocities in the region of Volcán de Colima, Mexico. More than 15 years of continuous records were processed, producing long time

Volatiles contents, degassing and crystallisation of intermediate magmas at Volcan de Colima, Mexico, inferred from melt inclusions [PDF]

open access: yes, 2018
In volatile-saturated magmas, degassing and crystallisation are interrelated processes which influence the eruption style. Melt inclusions provide critical information on volatile and melt evolution, but this information can be compromised significantly ...

Probabilistic analysis of rockfall frequencies during an andesite lava dome eruption:The Soufrière Hills Volcano, Montserrat [PDF]

open access: yes, 2005
A probabilistic analysis of rockfalls has been undertaken using seismometer-determined information on the timing and duration of rockfalls from the Soufrière Hills lava dome, Montserrat, between 1995 and 1997.

Quantification of magma ascent rate through rockfall monitoring at the growing/collapsing lava dome of Volcán de Colima, Mexico [PDF]

open access: yes, 2013
International audienceThe most recent eruptive phase of Volc'an de Colima, Mexico, started in 1998 and was characterized by dome growth with a variable effusion rate, interrupted intermittently by explosive eruptions. Between November 2009 and June 2011,

Blast waves from violent explosive activity at Yasur Volcano, Vanuatu [PDF]

open access: yes, 2013
Infrasonic and seismic waveforms were collected during violent strombolian activity at Yasur Volcano (Vanuatu). Averaging similar to 3000 seismic events showed stable waveforms, evidencing a low-frequency (0.1-0.3Hz) signal preceding similar to 5-6s the ...

Determination of the total grain size distribution in a Vulcanian eruption column, and its implications to stratospheric aerosol perturbation

open access: yesGeophysical Research Letters, 1980
Grain size analysis of samples representing all sampleable portions of the airfall deposit produced by the Fuego volcano in Guatemala on 14 October 1974 form the basis for estimating the total grain size distribution of tephra from this eruption. The region enclosed by each isopach has a particular average grain size distribution which can be weighted ...

Source process of Vulcanian explosion earthquakes at Sakurajima volcano, Japan, derived from seismic waveform inversion analysis in the very-long and long period bands and infrasound signals

open access: yesEarth, Planets and Space
Eruption models developed using the waveform inversion method for explosion earthquakes differ across studies, and a unified model has not been established. Here, Vulcanian eruption processes of the Sakurajima volcano, Japan, were clarified using seismic
