Intra‐Eruption Forecasting Using Analogue Volcano and Eruption Sets
AbstractForecasting the likely style and chronology of activity within an eruption is a complex issue that has received far less attention than forecasting the onset and/or the magnitude. By developing a global data set of coded phases (discrete styles of activity within previous eruptions), we can model the resulting data using a semi‐Markov chain ...

Intra-eruption forecasting [PDF]
Forecasting eruption onsets has received much attention, in both the short and long term. However, an eruption is not easily reduced to an instant in time, and forecasting what happens after eruption onset has received little attention. Any useful definition of an eruption has to allow for activity over scales ranging from days to decades, and can do ...

Ergodic seismic precursors and transfer learning for short term eruption forecasting at data scarce volcanoes [PDF]
Seismic data recorded before volcanic eruptions provides important clues for forecasting. However, limited monitoring histories and infrequent eruptions restrict the data available for training forecasting models.

Toward Forecasting Volcanic Eruptions using Seismic Noise [PDF]
During inter-eruption periods, magma pressurization yields subtle changes of the elastic properties of volcanic edifices. We use the reproducibility properties of the ambient seismic noise recorded on the Piton de la Fournaise volcano to measure relative

Hidden patterns in volcanic seismicity: deep learning insights from Mt. Etna’s 2020–2021 activity [PDF]
Understanding the temporal evolution of volcanic activity is crucial for eruption forecasting and hazard assessment. We use an unsupervised machine learning method, Deep Embedded Clustering, to classify daily seismic spectrograms of Mount Etna between ...

Understanding and forecasting sudden explosive eruptions. [PDF]
Abstract Explosive eruptions of VEI ≤ 3 commonly occur with few warning signs. Such eruptions can be magmatic, phreatomagmatic, or phreatic in nature, and they are driven by the catastrophic release of pressurized gas. Our challenge is how to better forecast these eruptions and better understand them with existing and new tools.

Anticipating volcanic eruptions using rescaled range analysis of volcano-tectonic seismicity [PDF]
The possibility of forecasting volcanic eruptions remains a major challenge for the volcanological scientific community. To date, various techniques based on volcano-tectonic seismicity, endogenous gas emission and satellite imagery have been widely ...

Probabilistic, Multi‐Sensor Eruption Forecasting
We developed an eruption forecasting model using data from multiple sensors or data streams with the Bayesian network method. The model generates probabilistic forecasts that are interpretable and resilient against sensor outage.

Jerk, a promising tool for early warning of volcanic eruptions [PDF]
Forecasting volcanic eruptions remains a great civil defense challenge in many parts of the world. Although instrumental monitoring networks provide a variety of signals interpretable as eruption precursors, volcano observatories still lack a systemic ...

Mitigation of human cognitive bias in volcanic eruption forecasting
Modern operational eruption forecasting methods rely heavily on human judgment in the face of uncertainty and are thus susceptible to myriad cognitive biases and errors by the scientist-forecasters.
