Hydrogeomorphology of Lava Rise Pits in The Laki Lava Field, Southeast Iceland
Lava Rise Pits (LRPs) are found within the Laki lava field in Southern Iceland. LRPs naturally occur in pahoehoe lava flows and form when the flow in lava tubes ceases and collapses. The goal of this study was to better understand the hydrogeomorphology of LRPs during the Fall-winter season. Three …

Automated Mapping of Lava: Classification of the Lava Flow Field from the 2021 Fagradalsfjall Eruption
… in the area. Near real-time mapping of the lava flow field is essential for hazard assessment during an eruption. This study aims to develop efficient automated mapping methods of lava flows that could be applied to future Reykjanes eruptions. Aerial photogrammetric data used to monitor the …

Meccanismi di formazione dei tubi di lava
… proposed to describe two different mechanisms of lava tubes formation. A first model is introduced to describe the development of a solid crust in the central region of the channel, and the formation of a tube when crust widens until it reaches the leve\'es. The Newtonian assumption is considered …

Viscoelastic Strain, Viscous Rheology, and Behavior of Experimental Lava Flows
<p>Basaltic pāhoehoe lava flows are prevalent throughout the terrestrial bodies of the solar system. This style of volcanism represents both a predominant resurfacing mechanism of planets and natural satellites and a natural hazard to populations living within volcanically active regions on Earth. …

Monitoring Erebus volcano's active lava lake; tools, techniques and observations
Active lava lakes present a rare opportunity to observe directly the complex processes occurring within a magma body. Situated on Ross Island, Antarctica, the 3794-m-high crater of Erebus volcano has hosted a phonolite lava lake for decades. Previous studies have shown that many of the lake’s …

Adding diversity and realism to LAVA, a vulnerability addition system
… and implemented several modifications to LAVA, a vulnerability addition system, with the goal of improving realism and diversity of the injected bugs. Specifically, I describe three separate improvements: a method to add fake bugs alongside real ones in order to decrease bug …

Interpretações da Operação Lava-Jato no mercado editorial brasileiro (2016-2021)
This study analyzes how the Car Wash Operation was interpreted within the Brazilian publishing market from 2016 to 2021. This specific timeframe covers the impeachment of President Dilma Vana Rousseff and extends to the moment Sergio Fernando Moro, the leading judicial figure of the Car Wash …

Fluvial Response to Intra-Canyon Lava Flows, Owyhee River, Southeastern Oregon
<p>At least six lava flows have entered the Owyhee River Canyon north of Rome, Oregon, since the Pliocene and directly impacted the Owyhee River. The effects on the river of the two youngest lava flows, the West Crater (60–80 ka) and Saddle Butte (> 60–90 ka), are readily apparent. These two lava …

Neuro-Fuzzy Classification of Submarine Lava Flow Morphology On the Galapagos Spreading Center, 92W
… to produce detailed volcanological maps of lava flow fields at the Galápagos Spreading Center (GSC). The maps are used to provide quantitative estimates of the abundance and spatial distribution of lava flow morphologies, which are used as a proxy for comparing average effusion rates within …

Lacustrine Sediment Record of Multiple Quaternary Lava Dams on the Owyhee River, Southeastern Oregon
<p>Multiple lava dams and correlating lakes impacted the Quaternary evolution of the Owyhee River. Sediment records from lava-dammed lakes were investigated to understand effects of the West Crater (WC) lava dam (~70 ka), the Saddle Butte 2 lava dam (~144 ka), and the Bogus Rim lava dam (~1.9 Ma). …
