Tidal modulation of the seismic activity related to the 2021 La Palma volcanic eruption. [PDF]
Sci Rep, 2023 The volcanic eruption at La Palma started on September 19, 2021. The eruption was preceded by a seismic swarm that began on September 11, although anomalous seismicity has been observed on the island since 2017.

Modeling Strombolian eruptions of Karymsky volcano, Kamchatka, Russia [PDF]
Journal of Volcanology and Geothermal Research, 2003 A model is proposed to explain temporal patterns of activity in a class of periodically exploding Strombolian-type andesite volcanoes. These patterns include major events (explosions) which occur every 3–30 min and subsequent tremor with a typical period of 1 s.

Transport of ballistic projectiles during the 2015 Aso Strombolian eruptions [PDF]
Earth, Planets and Space, 2019 Abstract Large pyroclasts—often called ballistic projectiles—cause many casualties and serious damage on people and infrastructures. One useful measure of avoiding such disasters is to numerically simulate the ballistic trajectories and forecast where large pyroclasts deposit.

The deep feeding system of Vesuvius involved in recent violent strombolian eruptions [PDF]
Geophysical Research Letters, 2005 Mt. Vesuvius has experienced a period of semipersistent volcanic activity over the last three centuries, producing mainly lava effusions and some mixed effusive‐explosive eruptions of higher magnitude. We present a systematic study on major and volatile elements of melt inclusions trapped in olivine crystals peculiar to lapilli fallout emplaced during ...

Linking eruptive style with pore network geometry in tephritic/basanitic tephra from the 2021 Tajogaite eruption (Canary Islands, Spain). [PDF]
Bull VolcanolInvestigating the textural properties and 3D geometry of the connected pore network in volcanic products provides insight into magma ascent processes, due to their influence on magma permeability, outgassing efficiency and explosivity.

Slow Ascent of Unusually Hot Intermediate Magmas Triggering Strombolian to Sub-Plinian Eruptions
Journal of Petrology, 2020 AbstractTo assess whether magma ascent rates control the style of volcanic eruption, we have studied the petrography, geochemistry and size distribution of microlites of plagioclase and pyroxene from historical eruptions from Tongariro, Ruapehu and Ngauruhoe volcanoes located in the southern Taupo Volcanic Zone, New Zealand.

High‐speed imaging of Strombolian eruptions: Gas‐pyroclast dynamics in initial volcanic jets [PDF]
Geophysical Research Letters, 2015 AbstractHigh‐speed imaging of Strombolian explosions brings into view the motion of pyroclasts upon leaving the volcanic vent. The erupted gas‐pyroclast mixtures form jets with well‐defined leading vortex rings that rise at almost constant velocity proportional to the time‐averaged velocity of pyroclasts.

THE 1723 A.D. VIOLENT STROMBOLIAN AND PHREATOMAGMATIC ERUPTION AT IRAZÚ VOLCANO, COSTA RICA
Revista Geológica de América Central, 2013 La erupción histórica más grande registrada en el Irazú, se inició el 16 de febrero de 1723 y se extendió por lo menos hasta el 11 de diciembre de ese año. El presente trabajo analiza críticamente los depósitos expuestos en la cima del Irazú, y se comparan con el relato del gobernador español, don Diego de la Haya, la única crónica de dicha erupción ...

From Passive Degassing to Violent Strombolian Eruption: the Case of the 2008 Eruption of Llaima Volcano, Chile [PDF]
, 2016 On 1 January 2008 Llaima volcano, a basaltic andesite stratocone in southern Chile, entered a phase of violent Strombolian eruption. Llaima, like many passively degassing systems, has experienced prolonged (decades-long) periods of persistent summit degassing from its open vent.

The bursting behavior of gas slugs: laboratory and analytical insights into Strombolian volcanic eruptions. [PDF]
, 2012 The aim of this thesis is to study how explosive behavior and geophysical signals in a volcanic conduit are related to the development of overpressure in slug-driven eruptions. A first suite of laboratory experiments of gas slugs ascending in analogue conduits was performed.
