Landslides are a globally significant natural hazard, and providing risk
assessment for assets in vulnerable locations is often of primary
importance. However, field-scale assessment of the geophysical parameters
that determine landslide hazard can be both time and cost-intensive, which
may not suit all needs. In particular, humanitarian crises often result in
displacement of populations either temporarily or for longer periods, and
these highly vulnerable populations may lack financial resources or
technical expertise to carry out landslide risk assessment, potentially
leaving them threatened by significant hazards. Simple, quickly deployable
methods for landslide risk assessment using globally available satellite
data could provide valuable information to stakeholders in highly
vulnerable locations with transient populations.

In this seminar, I’ll discuss our initial work building near real-time
hazard and exposure assessment models for landslides in data poor regions,
focusing primarily on a humanitarian case study: the Rohingya refugee camps
in Southern Bangladesh. Using primarily freely-available NASA satellite
data, and a novel set of machine learning methods that can flexibly
incorporate other data inputs, we have produced a regional susceptibility
map. Combining this with NASA IMERG near-real time precipitation data we
are able to provide near-real time hazard assessment. This flexible hazard
model can be combined either with Open Street Map data or infrastructure
data provided by stakeholders to provide either itemized or mapped risk
assessment for landslides.

Our initial foray into risk and hazard estimates has been full of lessons
learned, so as well as discussing our research methodology, I will also
talk about the valuable insights gained working with end-users for data
communication and how we’ve applied those to our next steps.
