Separating the thermal fingerprints of lava flows and simultaneous lava fountaining using ground-based thermal camera and SEVIRI measurements

, 2013
uring effusive eruptions, thermal satellite monitoring has proved well suited to map thethermal flux from lava flows. However, during lava fountaining events, thermal contributions from active flows and from the fountain itself cannot be separated in low

Monitoring lava lake fluctuations and crater refilling with continuous laser rangefinders

Journal of Applied Volcanology
The U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) has developed a new method to continuously monitor lava lake elevations. Since 2018, HVO has stationed a laser rangefinder on Kīlauea’s caldera rim.

How lava flows: New insights from applications of lidar technologies to lava flow studies

, 2013
Mafic lava flows are common; for this reason, they have long been a focus of volcanological studies. However, field studies of both older and active flows have been hampered by difficulties in field access; active flows are hot, whereas older flows have ...

LAVA FLOWS AT SAKURAJIMA VOLCANO (I)-VOLUME OF THE HISTORICAL LAVA FLOWS-

, 1981
The thickness and the volumes of the recent two lava flows (in 1914 and 1946) at SakurajimaVolcano are reexamined in details on the basis of the three topographic maps (published in 1909, 1920 and 1965) and two hydrographic charts (published in 1899 and ...

Three long lava flows in north Queensland

, 1998
The Kinrara, Toomba, and Undara basaltic lava flows are from 55 to 160 km long and range in age from 13 to 190 ka. The lavas were emplaced down low gradients (0.2° to 0.4°) with volumes ranging up to 30 km3. They were not unusually hot at eruption (1130°–

La Palma 2021 Eruption (Canary Islands): Measurements and Modelling of Lava Flow Cooling Rates and Applications for Infrastructure Reconstruction and Risk Mitigation

GeoHazards
On 19 September 2021, a strombolian volcanic eruption began on the island of La Palma in the Canary Islands. This event resulted in the destruction of 73 km of roads, urban infrastructure, numerous houses, and agricultural crops, affecting approximately ...

Visual Simulation of Lava Flows Employing Particle-based Approach

, 2003
This video demonstrates our new particle-based method for visually simulating lava flows. Employing our developed particle-based simulation models of viscous fluid dynamics and heat transfer, this method realizes the visual features of lava flows: lava ...

Hydroacoustic Evidence for Offshore Lava Emplacement During the 2018 Kīlauea Eruption

Geophysical Research Letters
During the 2018 Kīlauea eruption, over half the erupted lava was deposited on the seafloor. Lava flows crossing the shoreline generated sounds that were recorded by a network of hydrophones.
