Venue & field trip

The full week, including food and lodging as well as transportation will cost you only €500 (€425 for early career scientists).


The conference will be organized as a full package and the fee will cover everything from airport pickup to airport dropoff, including accommodation, all meals, and transportation. We will stay 2 nights at Bhrikuti View Hotel in Kathmandu.

During the field visit and the conference part in the Bhotekoshi valley, situated in the Ghorka rupture zone, we will stay at the Borderlands Resort.

Field trip

The second half of the conference will be held in the Bhotekoshi valley, providing an integrated field and conference experience. The proposed Bhotekoshi venue is in an area highly affected by the Gorkha earthquake, as well as by a range of other catastrophic events, including outburst floods, landslides and debris flows, and many of the associated impacts can be observed directly from the proposed venue. The travel from Kathmandu to the Bhotekoshi will double as a field excursion, during which we will observe the Jure landslide, a giant valley­blocking landslide from 2014, evidence of past mega­floods from extremely large boulders in the channel, interactions between infrastructure (hydropower facilities and roads) and landslides and floods, and an introduction to the Gorkha earthquake landslides and impacts.

During the time in the Bhotekoshi we will have an additional one day field trip where we will continue upstream through the region most heavily impacted by the 2015 earthquake and 2016 GLOF. We will observe the co­seismic landslides and the resulting cascade of debris from hillslopes through debris flows into the river channel, as well as the impacts of the recent 2016 glacial lake outburst flood, and of long­lived slow­moving landslides. We will introduce and discuss the post­earthquake monitoring infrastructure set up by several different groups in the region. The field excursion is planned in the middle of the program to allow for sufficient introduction before the trip and to promote discussion in the days following the trip. The costs will be including in the conference fee.

Registration and Support


During the conference, we will stay for the two first days in Kathmandu and move from there to the epicentral area of the 2015 Gorkha earthquake in the Bhotekoshi River valley, where the conference will continue at Borderlands rafting camp. The conference will include 1.5 days of field visits. The full week, including food and lodging as well as transportation will cost €525 (€445 for early career scientists).


Due to venue size, the conference will be limited to 80 participants (pre-registration deadline was 30 April 2019). All accepted participants will be provided with a registration link. In case any questions arise, please contact Christoff Andermann ( The deadline for final registration and payment is 31 August 2019.

Terms and conditions


  • Registrations are for the persons specified and are non-transferable.
  • Changes to registration invoices are only possible with regard to the invoice address or order references. Any such claims must be received by Copernicus Meetings no later than 6 weeks after the last day of the conference. Later requests cannot be considered.
  • Changes to the registration rate selected in the finalized registration form, including received invoice, can only be realized for unpaid invoices. Then, the attendee is asked to cancel the registration order and to place a new order through the registration form, including the correct registration rate. Please note that the deadline for registration is also valid in such cases.

Cancellation policy

  • Registration fees will only be refunded if the notice of cancellation is received by Copernicus Meetings before 31 August 2019. The cancellation fee is €50.
  • Cancellations after 31 August 2019 and no-shows are not eligible for a refund.
  • There is no reason (including but not limited to illness, inability to travel, visa application rejection, travel restrictions, etc.) for registration cancellation that makes the above-mentioned deadline for cancellations inapplicable.


The organizers cannot accept liability for personal accident, loss, or damage to private property, which may be incurred as a result of the participation in the conference. Participants are, therefore, advised to arrange appropriate insurance coverage. This should apply not only to travel but also to cancellation costs.

Travel support

Thanks to support from the EGU and the US National Science Foundation (NSF), we can offer a limited number of travel and registration grants to eligible participants.

EGU support is available for early career scientists (ECS), as defined by the EGU. ECS grants will be given to cover registration costs for the conference. The deadline for support application was 30 April 2019.

Key note speakers

Michael Manga, UC Berkeley, Hydrological responses to earthquakes

The presentation will address how different regions of the subsurface, from shallow unconsolidated sediment to deep fractured basement rocks, respond to stresses produced by Earthquakes. Observations to probe these interactions include changes in the water level and temperature in wells and the amount of water flowing in streams. High temporal resolution of water level changes in Long Valley caldera, California, are used to develop a model for seismic pumping of fluids between fractures.

Ed Tipper, Cambridge University, earthquake perturbation of sediment and weathering fluxes

Extreme events such as earthquakes scar landscapes. In mountainous regions earthquakes trigger land slides. These landslides perturb or perhaps dominate sediment delivery to rivers in areas of high uplift and erosion. To finger print the significance of this process a better understanding of sediment source and transport processes. This talk will review evidence for change in sediment source, flux and transport following major earthquakes and consider their importance in the delivery of matter from mountain regions.

Sara Rathburn, Colorado State University, precipitation, sediment and carbon transport

Extreme events are predicted to increase in step with climate change, altering Earth surface processes and landscapes. Of particular concern are disturbances that increase sediment delivery from hillslopes to channels because of the effects of increased sedimentation on aquatic ecosystems, channel and floodplain morphology, and water resource management including water quantity and quality. Within the last seven years, extreme flooding, wildfire, and mass movements have occurred within in the Front Range of Colorado, USA resulting in widespread hillslope erosion, morphologic channel change and avulsion, sediment pulse evolution and transport, and extensive deposition. Nested scales of analysis of flood effects from the September 2013 storms will be presented for two rivers; one burned by wildfire in 2012, and one unburned to evaluate channel recovery and sediment transport. The different pathways of recovery provide important insight into landscape resilience to future extreme events.

Karen Gran, University of Minnesota Duluth, fluvial recovery after volcanic eruptions

Mount Pinatubo, Philippines, erupted in June 1991, in the second biggest eruption of the 20th century. River valleys filled with pyroclastic flow deposits that were not hot enough to weld, leading to massive redistribution of sediment by lahars following the eruption. We studied channel recovery and evolution for two decades following the eruption, tracking sediment-laden channels as lahars ceased and normal fluvial processes were finally able to process and rework the channel bed. The Pinatubo eruption thus offered a unique look into how rivers process high volumes of sand-rich sediment, providing insights into river recovery following landslides, dam removals, or other extreme sediment-producing events.

Brian Buma, University of Denver, ecosystems disturbance and coupling with landscapes

Landslides result from complex interactions between geology, climate, weather, and a host of other factors – including the ecological aspects of the region. Vegetation plays a significant role in hillslope stabilization (with different species providing different aspects of protection), but it can also promote sliding by transferring horizontal wind forces to the ground. Furthermore, vegetation is often manipulated by people. Thus, the integration of the ecology of landslides with our geological understanding is important.

Flavio Anselmetti, University of Bern, earthquakes and sediment records

Instrumental and historic records cover only insufficiently the time span to provide critical information on maximum intensity and recurrence rates of natural hazards. Therefore, geologic archives are needed to expand the temporal coverage of disturbances to prehistoric time scales. Lake sediments, in particular, provide the high-resolution and continuous archives that may identify prehistoric disturbances. Due to their sensitivity to record hazards such as earthquakes, rock falls, floods and tsunamis, lacustrine systems allow long, detailed and quasi-complete catalogues providing critical data for deterministic or probabilistic hazard assessments.

Jamie Howarth, Victoria University of Wellington, earthquake cycles and carbon fluxes

Erosion of biospheric particulate organic carbon (POC), export by rivers and subsequent burial in ocean depocentres affects the atmospheric carbon reservoir over geological timescales. Quantifying POC fluxes from extreme events has proved challenging because responses to them often persist beyond the duration of instrumental data series. We overcome this challenge by using sedimentary archives of earthquake-induced erosion. These records show that large earthquakes can significantly contribute to both carbon export from mountain forests and burial in the deep ocean over millennia timescales providing a direct link between active tectonics and the surface carbon cycle.
