Conference Objectives

The objective of this conference is to bring together volcanologists, structural geologists, engineering geologists and geophysicists working on the reciprocal influence of volcanoes and their basement. A core group of geoscientists working with the United Nations Educational Scientific and Cultural Organizaton-International Union of Geology and Geophysics-International Geological Correlation Program (UNESCO-IUGG-IGCP) project no. 445 and the National Institute of Geological Sciences, University of the Philippines shall spearhead the conference. This IGCP sponsored correlation program is multidisciplinary and is focused towards the understanding of the effects of basement, structure, and stratigraphic heritages on volcano growth, evolution and behaviour. The proposed Chapman conference itself, aims to correlate research findings and discuss new discoveries on the interplay between the growth of volcanoes and their basement, a subject, which is until today, poorly investigated. In particular, target results on this specific topic of volcano-tectonics will include: the correlation of the results of research on recent and active volcanic areas, as well as older, deeply eroded volcanic remnants in the circum-Pacific plate converging zones, East Africa rift, oceanic and continental intra-plate volcanic regions of the Atlantic and Asia, Antarctica, and plate boundary complex sectors in the Mediterranean region; comparison of analogue and numerical models with natural examples from a representative global data set of volcanoes; evaluation of basement-volcano stability and the identification of their related geohazards; development of techniques and skills to assess the beneficial and adverse impacts to society of the interaction between volcanoes and their basement (i.e. guides for geothermal energy resources and landslide vulnerability assessment); and lastly, discussions on the creation of a database with a view to performing the statistical analysis of selected geotechnical, petro-geochemical, and geochronology data.

Conference Overview

The basement can influence the evolution and behaviour of volcanoes due to several possible factors. These factors can be mainly linked to the geological, structural and geomorphological character of the basement and can control the formation of intrusive and effusive complexes, dry and eruptive fracture systems, calderas and sector collapses. Conversely, the volcanic edifice can modify the character of its substratum. The extent of this interplay between the volcano and the substratum is fundamental to our understanding of the evolution of volcanoes. It is necessary for the proper assessment of volcanic and related geologic hazards. This includes the understanding of the reciprocal influence between volcanoes and their basement, which may lead to tsunami-generating phenomena. With a wide variety of volcanoes found in different geodynamic settings, a multidisciplinary approach in the investigation of this topic is imperative. Research work in different volcanic regions and geodynamic settings should be correlated. This meeting will bring together researchers working with data collected in different regions using diverse approaches to improve our understanding about the interaction between volcanoes and their substratum.

Conference Format (tentative)

The conference is scheduled for 5 days and will include 3 days of presentations and 2 days field trip. The three days of presentation of papers and posters will include 6 thematic sessions with each session representing a disciplinary approach to the study of basement effects on the evolution of volcanoes and vice-versa. The following are the thematic sessions arrange in the following groups:

FIRST DAY: FROM DEEP TO SURFACE STRUCTURES IN VOLCANIC ZONES

Morning session: Geophysics and seismology

Afternoon session: Neotectonics, paleoseismology and structural geology

SECOND DAY: FROM INTRUSIONS TO VOLCANIC ROCKS

Morning session: Geochemistry and petrography

Afternoon session: Stratigraphy and surface geology

THIRD DAY: FROM GEOTECHNICS TO MODELLING OF BASEMENT-VOLCANOES

Morning session: Engineering geology, rock and soil mechanics

Afternoon session: Analogue and numerical modeling

The first day will cover geophysics, seismology, neotectonics, paleoseismology and structural geology. The second will be devoted to geochemistry, petrography, stratigraphy and surface geology. The third day will be the sessions on engineering geology, rock and soil mechanics, and geophysics and seismology of volcanic regions. The fourth and fifth days will be the field trip to Taal Caldera, a large volcano tectonic depression located about 100 km south of the conference venue. This caldera is part of the Macolod Corridor, a northeast-trending zone of persistent volcanism that is believed to be a pull-apart rift system. The volcanic features within the corridor are two volcano-tectonic depressions (Taal and Laguna de Bay); stratovolcanoes (Makiling, Banahaw and Malepunyo volcanoes); domes (e.g. Olila, Cumbantog); and more than 200 scoria cones and maars (Oles et. al., 1991). Some volcanoes, a geothermal field, and faults within the Macolod Corridor shall be visited during the field trip.

Sessions held during the first three days will start at 8:00 am and will end at 3:00 pm. There will be a 15 minute morning coffee break at 10:00 and a lunch break at 12:00. The afternoon sessions will resume at 1:00 pm and will end at 3:00 pm. The poster sessions will then begin at this point, where coffee and light drinks will be served.

Poster sessions on the topic of the day will be held in an area adjacent to the oral presentation venue. Poster sessions will be encouraged as this type of presentation fosters a relaxed atmosphere that encourages lively discussions over a relatively long period of time. The poster sessions will be held from 3:00-6:00 pm each day. The titles and abstracts of the posters shall be flashed on screen during the end part of the daily oral presentations. This will give the participants an opportunity to view what is in store at the end of the day. Sessions chairs shall request the poster authors to stand beside their work. About 30 poster presentations are expected.
