3 Sep 2023

Time:

09:00 - 15:00 BST (TBC)

Convenors

Joanne Kwan (CIRIA)
Charlotte Usher (RSK Geophysics)

The construction industry research and information association (CIRIA) is a neutral, independent body in the UK set up to provide guidance and knowledge sharing for the construction industry. Based on the CIRIA research proposal (RP) 1146, the lead contractors RSK alongside a project steering group have been working on updating the C562 standard, published in 2002, to demonstrate good practice on the use of geophysics in ground investigations to be finalised in 2023. This workshop could be used to present the new standards for geophysical support of ground investigations.

Workshop 1 Geophysical Exploration in Volcanological Areas: Imaging Challenges and Public and Operational Constraints

Date:

7 Sep 2025

Time:

09:00 -17:00 CEST (subject to change)

Room:

Available soon!

Convenors:

Pier Paolo Bruno (Università degli Studi di Napoli Federico II)
Paola Ragazzo (Eni)

Overview

Volcanological areas present a unique challenge for geophysical exploration due to their highly heterogeneous subsurface structures, complex fluid-rock interactions, and dynamic temporal evolution. Traditional seismic inversion techniques often struggle to resolve the intricate nature of these environments. However, advances in both passive and active seismic data inversion— along with joint inversion methodologies incorporating other geophysical techniques—offer new insights into subsurface imaging in these complex settings.
This workshop will focus on the latest methodologies for geophysical inversion in volcanological areas, emphasizing both active source and ambient noise (passive) seismic data. Additionally, we will explore joint inversion approaches that integrate seismic, gravity, electromagnetic, and other geophysical datasets to enhance our understanding of volcanic systems.

Key Topics

• Seismic inversion in volcanic environments: Challenges and advancements in active and passive seismic techniques.
• Joint inversion strategies: Combining seismic with other geophysical methods (e.g., gravity, magnetotellurics, electrical resistivity) for improved imaging.

• Fractal density and subsurface complexity: Volcanic structures often exhibit self- similar, scale dependent heterogeneity, akin to fractal geometry. How can inversion techniques account for and leverage this fractal nature?
• Case studies from the Phlegraean Fields and other active volcanic regions: Applications of modern inversion techniques to improve subsurface characterization.
• Future directions in geophysical exploration of volcanological areas: New technologies and methodological approaches.
• Public Communication & Risk Perception: Build effective plans to engage local communities to ensure acceptance of geophysical studies; lessons from past.

Participant Profile

This workshop will bring together researchers and industry professionals to discuss cutting- edge developments in geophysical exploration and inversion techniques tailored to the complexities of volcanic settings.

Overview

Volcanological areas present a unique challenge for geophysical exploration due to their highly heterogeneous subsurface structures, complex fluid-rock interactions, and dynamic temporal evolution. Traditional seismic inversion techniques often struggle to resolve the intricate nature of these environments. However, advances in both passive and active seismic data inversion – along with joint inversion methodologies incorporating other geophysical techniques – offer new insights into subsurface imaging in these complex settings.
This workshop wants to be a deep dive into seismic data opportunities and challenges using Campi Flegrei area as a case study. Public consensus and the latest methodologies for geophysical inversion in volcanological areas, emphasising both active source and ambient noise (passive) seismic data will be explored.
Additionally, we will explore joint inversion approaches that integrate seismic, gravity, electromagnetic, and other geophysical datasets to enhance our understanding of volcanic systems.

Preliminary Schedule
09:00	Key Challenges & Background 1. Dr. Mauro Di Vito (INGV Osservatorio Vesuviano) (TBC) Current State of Campi Flegrei: Geological & Geophysical Challenges 2. Speaker from Protezione Civile / ENI/ INGV (TBC) Risk Perception and Public Communication in Densely Populated Areas Followed by Q&A
10:30	Coffee Break
11:00	Round table discussion and breakout groups Goal: Develop an integrated geophysical exploration plan for onshore and offshore Campi Flegrei while addressing societal and environmental constraints. Participants will be divided into smaller expert panels, each tackling a specific challenge and proposing solutions: - Onshore Exploration: How to overcome high noise and attenuation? Can dense acquisition geometry provide the results of heavy acquisition (less appreciated in urbanized context)? - Offshore Exploration: How to design seismic surveys in restricted offshore areas? Dealing seismic acquisition on restricted offshore area. Evaluation of survey design strategy and integrate activity between exploration and monitoring. - Subsurface Imaging & Method Integration: How to combine onshore and offshore, active and passive seismic data? How to incorporate other geophysical methods (gravity, EM, MT) for joint inversion? - Public Communication & Risk Perception

Workshop 3 Hard Rock Physics

Date:

8 Sep 2024

Time:

09:00 - 17:00 EEST

Room:

TBC

Convenors:

Risto Kiuru (Rock Physics Finland Ltd, Finland )
Tuija Luhta (Geological Survey of Finland, Finland)

Workshop description

To fully understand and properly calibrate geophysical models, information on the physical properties of the rock mass is essential. Traditionally, literature and research on the topic has been quite heavily biased towards soft sedimentary environments. We propose a workshop on research and applications of rock and mineral physics in hard rock environments, specifically in the context of mineral exploration, mining and rock construction. Topics covered could include, e.g., laboratory testing of the physical properties of rocks and minerals, in situ physical property measurements, and application of physical property data to the development, calibration and interpretation of geophysical data and physical property models.

Participant profile

Researchers working on physical properties of rocks and minerals, both in the laboratory and the field
Students of the relevant disciplines
Practitioners using physical property data of rocks and minerals in their work
Practitioners that could benefit from using physical property data, such as those working with geophysical models or 3D physical property models

Draft schedule

10:00-13:00 On the first half of the workshop, convenors will present a compact introduction into rock and mineral physics, laboratory testing and further use of the data for those less familiar with the subject.

13:00-14:00 Lunch break

14:00-17:00 On the second half of the workshop, select participants will present their latest research and case studies. Adequate time will be reserved for discussion.
