Lava dome growth and mass wasting measured by a time series of ground-based radar and seismicity observations [PDF]

, 2008
Exogenous growth of Peléean lava domes involves the addition of lava from a central summit vent and mass wasting on the flanks as rockfalls and pyroclastic flows.

Lava production at Soufriere Hills Volcano, Montserrat: 1995-2009 [PDF]

, 2010
[1] We estimate that about 1 km3 of andesitic lava has been produced at Soufrière Hills Volcano, Montserrat from 1995 to 2009. There were three major episodes of extrusion, each lasting about 2 to 3.5 years and producing about 280 to 340 M m3 of lava ...

Lava flow daily monitoring: the case of the 19 September–5 October 2022 eruption at Piton de la Fournaise

Volcanica, 2023
Taking prompt and effective actions to mitigate risks associated with an effusive eruption greatly depends on the monitoring of lava flow emplacement. Here we report on the monitoring of the lava flow emplaced during the 19 September to 05 October 2022 ...

Terrestrial analogs and thermal models for Martian flood lavas [PDF]

, 2000
The recent flood lavas on Mars appear to have a characteristic “platy-ridged” surface morphology different from that inferred for most terrestrial continental flood basalt flows.

The influence of surficial features in lava flow modelling

Journal of Applied Volcanology, 2020
Lava flows can cause substantial and immediate damage to the built environment and affect the economy and society over days through to decades. Lava flow modelling can be undertaken to help stakeholders prepare for and respond to lava flow crises ...

Modelling and simulation of a lava flow affecting a shore platform: a case study of Montaña de Aguarijo eruption, El Hierro (Canary Islands, Spain)

Journal of Maps, 2021
Recent subaerial volcanism at El Hierro Island (Canary Islands, Spain) consists of monogenetic volcanic fields. This volcanism generated cinder cones, tephra air-fall deposits, and lava flows.

Icelandic analogs to Martian flood lavas [PDF]

, 2004
We report on new field observations from Icelandic lava flows that have the same surface morphology as many Martian flood lava flows. The Martian flood lavas are characterized by a platy-ridged surface morphology whose formation is not well understood ...

Lava flow crises in inhabited areas part I: lessons learned and research gaps related to effusive, basaltic eruptions

Journal of Applied Volcanology, 2020
Lava flows have threatened and/or inundated inhabited areas and/or their supporting networks 38 times at 12 volcanoes in the past 70 years. A systematic evaluation of these events has not been undertaken, making it hard to compare eruptions, create lava ...
