Mount St. Helens Retrospective: Lessons Learned Since 1980 and Remaining Challenges

Frontiers in Earth Science, 2018
Since awakening from a 123-year repose in 1980, Mount St. Helens has provided an opportunity to study changes in crustal magma storage at an active arc volcano—a process of fundamental importance to eruption forecasting and hazards mitigation.

Overcoming data scarcity for probabilistic eruption forecasting at data-limited volcanoes

, 2022
Data scarcity is one of the main sources of uncertainty in eruption forecasting. Due to multiple factors, such as the location or the poor preservation of deposits, numerous volcanoes have incomplete records of eruptions.

Accurate hindcasting of explosive eruptions at Whakaari, New Zealand

Volcanica
Phreatic eruptions are small, sudden events, commonly with few precursory signals. They are driven by interactions between magmatic and hydrothermal processes at shallow levels beneath the surface.

Thermal Remote Sensing for Global Volcano Monitoring: Experiences From the MIROVA System

Frontiers in Earth Science, 2020
Volcanic activity is always accompanied by the transfer of heat from the Earth’s crust to the atmosphere. This heat can be measured from space and its measurement is a very useful tool for detecting volcanic activity on a global scale.

Generalized Eruption Forecasting Models using Machine Learning Trained on Seismic Data from 24 Volcanoes

, 2023
Seismic data collected before volcanic eruptions holds important clues for forecasting future eruptions. However, many volcanoes have short monitoring histories or have infrequent eruptions.

δD and δ18O variations of the magmatic system beneath Deception Island volcano (Antarctica): Implications for magma ascent and eruption forecasting

, 2020
Geochemistry of volatiles in active volcanoes provides insights into the magmatic processes and evolution at depth, such as magma evolution and degassing, which can be implemented into volcanic hazards assessment.

Magma displacements under insular volcanic fields, applications to eruption forecasting: El Hierro, Canary Islands, 2011–2013 [PDF]

, 2014
Significant deformations, followed by increased seismicity detected since 2011 July at El Hierro, Canary Islands, Spain, prompted the deployment of additional monitoring equipment. The climax of this unrest was a submarine eruption first detected on 2011

Forecasting volcano eruption activity

, 2022
Volcanic activity monitoring typically are based on gas emissions, seismic activity, thermal anomalies, deformation and surface change. These events can be extracted by globally tracked observation data that span the electromagnetic spectrum. Orbital earth observation is generated by sensors focusing on different wavelength.

Revised calendar date for the Taupo eruption derived by ¹⁴C wiggle-matching using a New Zealand kauri ¹⁴C calibration data set

, 2011
Taupo volcano in central North Island, New Zealand, is the most frequently active and productive rhyolite volcano on Earth. Its latest explosive activity about 1800 years ago generated the spectacular Taupo eruption, the most violent eruption known in ...
