The IAVCEI Commission on Volcanic and Igneous Plumbing Systems invites you to join us for the next #FocusOnVIPS Online webinar. Our aim of these short online talks is to showcase the exciting research going on in our VIPS community and promote discussion across methodologies and disciplines. Each session features invited speakers presenting their latest work and ideas in brief talks, followed by questions and constructive discussions.
Each #FocusOnVIPS webinar will take place on MS Teams and they will not last over one hour. You must register in advance to attend using the link below.
Our next #FocusOnVIPS talks will focus on From Dykes/Dikes to Fissures with two invited speakers:
- Dr. Javi Ruz-Ginouves, University of Otago, New Zealand. “The Great Dyke Bake Off: Flow kinematics and thermal evolution of a short-lived dyke from the Hopi Buttes Volcanic Field, Arizona“
- Dr. Marius Paul Isken, GFZ German Research Centre for Geosciences, Germany. “Data-driven Earthquake Monitoring: Insights into Volcanic Crisis Reveals Coupled Magma System at Santorini and Kolumbo”.
📅 Date: Friday 2nd October
🕛 Time: 8AM (UTC)
🕐 Duration: 1 hour
🔗 Connection link for Registration: https://forms.gle/RoQo6ReEDCKTfdTQ6
We look forward to seeing you as we catch up with the latest VIPS research.
Please feel free to share this invitation with colleagues and students who may be interested.

***TALK ABSTRACTS***
The Great Dyke Bake Off: Flow kinematics and thermal evolution of a short-lived dyke from the Hopi Buttes Volcanic Field, Arizona
Dr. Javi Ruz-Ginouves, University of Otago, New Zealand
Distributed volcanic fields pose significant hazards to populated regions, yet their small-volume eruptions often lack contemporary records. Thus, reconstructing subsurface feeder systems is essential for understanding the dyke emplacement processes that may influence eruption dynamics. Here, we examine a near-surface, ~1,500 m long Miocene dyke in the Jagged Rocks complex, one of 300 small-volume volcanoes within the Hopi Buttes Volcanic Field (Arizona). Quantitative analysis of over 10,000 vesicles and phenocrysts reveals margin-parallel banding and localised lateral flow patterns driven by circulatory magma movement. Furthermore, thermal demagnetisation, rock magnetic analyses, and 1-d heat conduction models of the adjacent mudrock show localised heating up to 580 °C and complete remagnetisation within 0.5 meters of the contact. Together, these textural and paleomagnetic signatures demonstrate that short-lived magma flow within sub-meter monogenetic dykes occurs on a timescale of days, creating complex flow dynamics and heterogeneous thermal impacts.
Data-driven Earthquake Monitoring: Insights into Volcanic Crisis Reveals Coupled Magma System at Santorini and Kolumbo
Dr. Marius Paul Isken, GFZ German Research Centre for Geosciences, Germany
The rapid growth of seismic data calls for high-performance, scalable analysis tools to resolve complex geodynamic processes at volcanic edifices. Here, we introduce a new framework for scalable real-time, high-precision event detection and localization across large seismic datasets. We apply this framework to the 2025 Santorini–Kolumbo seismic crisis enabling high-resolution tracking of a 13-km-long upper-crustal dike intrusion (0.31 km³) and associated fault reactivation. By fusing offshore and onshore observations with AI-driven seismic detection, we unravel the spatiotemporal evolution of deep magma coupling and deflation-inflation dynamics between the twin volcanic centers, demonstrating the power of scalable AI workflows for real-time monitoring and volcanic risk assessment.
