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 ...

Gas slug ascent through changes in conduit diameter : Laboratory insights into a volcano-seismic source process in low-viscosity magmas. [PDF]

, 2006
Seismic signals generated during the flow and degassing of low-viscosity magmas include long-period (LP) and very-long-period (VLP) events, whose sources are often attributed to dynamic fluid processes within the conduit.We present the results of ...

The cascading origin of the 2018 Kīlauea eruption and implications for future forecasting

Nature Communications, 2020
The 2018 summit and flank eruption of Kīlauea Volcano was one of the largest volcanic events in Hawaiʻi in 200 years. Data suggest that a backup in the magma plumbing system at the long-lived Puʻu ʻŌʻō eruption site caused widespread pressurization in ...

Geophysical characterization of hydrothermal systems and intrusive bodies, El Chichón volcano (Mexico) [PDF]

, 2011
[1] The 1982 explosive eruptions of El Chichón volcano (Chiapas, Mexico) destroyed the inner dome and created a 1-km-wide and 180-m-deep crater within the somma crater.

Review of the 2022 eruption of Tonga Volcano —Implications for domestic volcano monitoring researches

地球与行星物理论评, 2022
On January 15th, 2022, a submarine volcano in Tonga erupted violently and explosively, ejecting a large amount of ash, gas and water vapor which entered the stratosphere to form a huge ash cloud.

Prevalence of Seismic Rate Anomalies Preceding Volcanic Eruptions in Alaska

Frontiers in Earth Science, 2018
Seismic rate increases often precede eruptions at volcanoes worldwide. However, many eruptions occur without such precursors. Additionally, identifying seismic rate increases near volcanoes with high levels of background seismicity is non-trivial and ...

Short-Term Forecasting and Detection of Explosions During the 2016–2017 Eruption of Bogoslof Volcano, Alaska

Frontiers in Earth Science, 2018
We describe a multidisciplinary approach to forecast, rapidly detect, and characterize explosive events during the 2016–2017 eruption of Bogoslof volcano, a back-arc shallow submarine volcano in Alaska’s Aleutian arc.

Officially social: Developing a social media crisis communication strategy for USGS Volcanoes during the 2018 Kīlauea eruption

Frontiers in Communication, 2023
The USGS Volcano Science Center has a long history of science and crisis communication about volcanoes and their eruptions. Centered mainly on websites, email notifications, traditional media, and in-person interaction in the past, our toolkit has ...
