Dear colleague,

On behalf of the Local Organizing Committee and the International Association of Volcanology and Chemistry of Earth´s Interior (IAVCEI) I am pleased to invite you to the 8th International Maar Conference (8IMC), which will be held in Petropavlovsk-Kamchatsky, Russian Federation, on 24-30 August, 2020. The 8IMC is a multidisciplinary congress on maar volcanoes, crater-lakes, and monogenetic volcanism. (see information below: First Circular. Second Circular.)

We hope you will consider presenting the results of your research in the next IMC.

Best regards,

Alexei Ozerov, chair of the 8IMC


Since the first "International Maar Conference" (IMC) meeting, the series has become one of the most successful discussion forums in volcanology, mainly because it provides a unique opportunity to bring together people from many different volcanological fields (geologists, physical volcanologists, sedimentologists, modellers, geophysicists, petrologists, etc.) with researchers from environmental and post-volcanic subjects. Previous IMC meetings have been held in volcanic areas that present different problems in terms of eruption dynamics, products, and landforms. The venue of the next IMC will be Kamchatka – one of the most volcanically and seismically active regions on Earth. Besides 30 active volcanoes, Kamchatka hosts more than 20 monogenetic volcanic fields located both in frontal and back-arc settings. This volcanic region provides a unique place for holding this multidisciplinary volcanological forum due to its highly active nature. We suggest making a special focus at 8IMC on the subduction dynamic and its influence on the onset and development of monogenetic volcanism and phreatomagmatism.

The conference will include five days of scientific sessions, which will combine keynote speakers, oral presentations and posters. The field trips which will be scheduled during this meeting, will allow the participants to explore the diversity of volcanic landforms of this area focusing on monogenetic volcanism and phreatomagmatism.

Scientific program

Session 1. Morphology and structure of maars and monogenetic volcanoes.

Session Leader:

Alison Graettinger

Monogenetic volcanic landforms preserve evidence of the construction, modification and preservation of volcanic deposits from small volume eruptions. This session invites contributions about the morphology, architecture, and distribution of explosive and effusive small volume eruptions including subsurface structures as in maar-diatremes. The morphology of individual landforms and comparisons of size and shape across groups of landforms can be used to help reconstruct eruption history, associated hazards, and interactions with surrounding geology. This session encourages contributions on the full spectrum of monogenetic volcanic features including maar-diatremes, scoria cones, spatter ramparts, and lava flows. Contributions from field studies, numerical and analog modelling, remote sensing, geophysical techniques, and spatial analyses are welcome.

Сессия 2. Session 2. Eruption mechanism of maars and associated volcanoes.

Session Leader:

Alexander Belousov

Originally maars were considered as craters of pure gas eruptions which ejected no juvenile magmatic material. Later quenched juvenile pyroclasts were recognized in most of the maar deposits and it became widely accepted that maars are products of phreatomagmatic eruptions from a highly explosive interaction between ascending magma and groundwater. Recently however appeared evidences that at least some maars were formed by violent release of CO2 probably of mantle origin. This session invites multidisciplinary submissions that will provide insight into eruptive mechanisms of maars based on investigation of lithology of maar deposits, properties of the erupted juvenile material. Presentations that investigate the link between maar forming eruption mechanism and more magmatic explosive eruption-driven eruption styles (such as Strombolian for instance) are particularly welcome.

Session 3. Monogenetic volcanoes: eruption dynamics, magma plumbing systems, structure, physical and petrological modeling.

Session Leader:

Xavier Bolós

This session invites scientific contributions about eruption dynamics of monogenetic volcanoes, their internal structure, and the physical and petrological modelling of its magma plumbing system.

Small-scale basaltic volcanic systems are the most widespread forms of magmatism on the planet and are expressed at the Earth’s surface as fields of small volcanoes which are the landforms resulting from explosive and effusive processes triggered by the rise of small batches of magma. This session is concerned with the growth, geomorphology, eruption dynamics, geodynamic distribution and degradation of this type of volcanism. Monogenetic volcanoes distribution inside a volcanic field depends in each case on their regional and local tectonic controls. The great variety of eruptive styles, edifice morphologies, and deposits shown by monogenetic volcanoes are the result of a complex combination of internal (magma composition, gas content, magma rheology, magma volume, etc.) and external (regional and local stress fields, stratigraphic and rheological contrasts of substrate rock, hydrogeology, etc.) parameters, during the magma transport from the source region to the surface. This is meant to be a multi-disciplinary session and we invite contributions that include different type of methods, such as; field studies, geophysical methods, numerical and analogue modeling of volcanic processes, GIS analysis, and petrological studies focused on its magma plumbing system and eruption dynamics.

Session 4. Petrology, geochemistry and characteristic times of magmatic processes at monogenetic volcanism.

Session Leader:

Tatiana Churikova

Petrology and geochemistry of the volcanic objects are the surface representation of the deep underground processes, which are controlled by regional and local tectonic conditions. Among other volcanic objects, monogenetic volcanism, including large monogenetic fields, flank areal volcanism, diatremes and phreatomagmatism, with its abundance of mafic lavas produces the least contaminated rocks and therefore is informative to study the primary mantle sources and processes. Due to high source-tosurface ascent rates, the composition of zoned minerals from the monogenetic events often keeps information about times of such processes as magma ascent, magma mixing, magma chamber replenishment, fractional crystallization and crustal assimilation. Correlation of these times with geophysical and observed parameters and events improve the understanding of eruption mechanisms and its forecasting. We invite contributions that include field observations, petrological, geochemical, and isotopic data, as well as diffusion timescales records based on the distributions of the chemical compositions in minerals.

Session 5. Volcanic hazard and risk assessment in monogenetic volcanic fields.

Session Leader:

Gabor Kereszturi

A volcanic field is produced by distributed basaltic to rhyolitic volcanism of a variety of explosive and effusive eruption styles, which is often termed monogenetic. These types of eruption are often episodic and characterized by short periods of intense activity (e.g. days to years). Moreover, each new eruption occurs in a distinct location, rather than repeatedly from the same site, such as at polygenetic volcanoes. This apparent evolution pattern and overall behavior make eruption forecast and volcanic hazard assessment of monogenetic volcanic fields extremely complex. In contrast, many monogenetic volcanic fields are situated near critical infrastructure, transport routes and large populations, requiring continuous development and refinement of the current practice of volcanic hazard assessment. This session invites submissions to further our understanding of volcanic hazards within active monogenetic volcanic fields, including but not limited to field-based, remote sensing, numerical modelling, geophysical and statistical approaches.

Session 6. Maar lakes and environment.

Session Leader:

Dmitri Rowet

Most volcanic lakes on Earth are maar lakes. Many maar craters are occupied by a lake. These two strong statements require major attention in future research. On the one hand, the presence of water intrinsically inhibits the study of the geological record, as a large portion of volcanic deposits is submerged by the lake. On the other hand, the deep anoxic water enables to preserve volcanogenic as well as allochthonous sediments. As such, the investigation of the well preserved sediment cores permits to (1) reconstruct the past volcanic activity, in time (100-1000s of years) and space (crater vs field), (2) detail the genetic process of the maar crater, (3) detect inter-eruptive periods, limnic gas bursts and possible climate change events that alternated with volcanic activity in the area. Thorough insights into the architecture of aquifers surrounding maar lakes and their relation with the lake itself helps to assess future hazardous scenarios (e.g. phreatomagmatic activity) for monogenetic or polygenetic maar fields. Moreover, the limnology of the lake water permits to trace back on the year to decade time scale. How stable is the lake water stratification throughout the seasons and years? Are there any signs of active volcanic input (e.g. sublacustrine hot springs or degassing vents)? Is CO2 accumulated in the deep lake strata, up to critical conditions to cause a “Nyos-type” gas burst? What is the relation between the lake’s thermal regime and the tectonic environment (e.g. geothermal heated deep rift lakes)? This session seeks for studies on (1) the sedimentology of lake core sections and its relation to the reconstruction of the genetic processes of the lake basin, (2) physical and biological limnology of the lake water, (3) geochemistry of water and dissolved gases of maar lakes.

Session 7. Maars and monogenetic volcanoes in geoheritage and geoconservation.

Session Leader:

Karoly Nemeth

Monogenetic volcanoes are commonly defined as erupting only once during their eruptive history through distinct eruptive phases. Systematically or randomly changing magma discharge rates, fluctuation of external versus internal influences on the eruption styles, and magmatic versus phreatomagmatic fragmentation can produce a great range of volcano types in terrestrial and subaqueous environments. In addition, monogenetic volcanic fields are the most common manifestation of volcanism on Earth hence they exist in every geotectonic settings and geoenvironments. As monogenetic volcanism played an important role in the global magmatism through the Earth history, there are monogenetic volcanic fields through the entire time of the evolution of Earth, hence we can come across with active, young or old eroded varieties of them. This extraordinary variety of monogenetic volcanism making it a very suitable subject to utilize them for geoeducation particularly for demonstrating of the variety of volcanic hazards. The small size, and the relatively simple volcano architecture that formed over short time making monogenetic volcanoes “human-scale” volcanic features hence perfect sites to promote volcanology to the general public. Monogenetic volcanic fields carry high geoheritage value especially if their eruptions influenced human society, they have high aesthetic value, or they are used as reference areas to describe unique volcanic processes. The complex geoheritage aspect of monogenetic volcanism has recently been recognized in geoconservation point of view and more and more monogenetic fields are in the frontline in various level of geopark establishments. In this session we call submissions that highlight this complex geoheritage aspects of monogenetic volcanism and its main volcanic landforms such as maars, tuff rings, tuff cones and scoria cones. Presentations that deal with various evaluation method to define the geoheritage values of monogenetic volcanic landforms as well as their link to human society, archaeology, indigenous world views and art are particularly welcomed in this session. Works that link modern and intact volcanic landforms to old eroded fields to utilize the geoeducation values of monogenetic volcanoes are also expected to be presented in this session. Works presenting new and advanced technologies applied in understanding the interaction of human societies with volcanic fields especially linking social studies, archaeology and volcano science are most welcome to this session.
