Dear colleagues,
Deadline is quickly approaching, so we kindly remind you to submit your
abstracts to the session  "1.11: *Large- to small-scale
instability-to-collapse processes and mass wasting: dynamics, models and
hazard implications*" of the next Cities on Volcanoes conference that will
be held in Heraklion (Crete) from June 12 to 17.
Abstract Deadline: February 13

Conveners:
Rosanna Bonasia, Alessandro Bonforte, Federico Di Traglia, Felix Gross,
Irene Manzella, Matteo Roverato

Session description:

*S1.11 > Large- to small-scale instability-to-collapse processes and mass
wasting: dynamics, models and hazard implications*

Mass-wasting in volcanic environment, both on-shore and subaqueous,
comprises a wide spectrum of phenomena, from large lateral collapse to
shallow debris remobilization that represent a major threat for societies.
Slope stability ranges from slow and continuous to sudden and catastrophic
and the interpretation of such events is challenged by the complex and
evolving interactions between tectonic, magmatic, fluid, and gravitational
processes. The moving masses can behave in different ways depending on
water content and flow rheology and can demonstrate different modes from
flank spreading or collapse to granular or viscous flow. Water plays an
important role in the transport and emplacement mechanisms of the flows,
enhancing their run-out and destructive power. Many volcanoes worldwide are
located in tropical, high-precipitation environments or are covered by snow
or glaciers, which exacerbates the potential for landslides, lahars, and
debris avalanches. In most cases, volcano slopes continue below sea level
and also subaqueous volcano flanks can be prone to mass wasting, often
affected by terrestrial volcano built-up and activity. This session
encourages multidisciplinary contributions from both earth and social
scientists that critique, explain and discuss how high-resolution
vulnerability and risk analysis and volcanic mass flow studies are
necessary to reduce disaster risk within vulnerable populations. We expect
contributions that integrate field-based geological and geochemical
studies, geomorphological mapping, geophysical investigations, remote
sensing, and analytical, numerical, and analogical modelling.
