The Community Engagement Office invites you to join us in a special series of games that was jointly developed by EOS Scientists and BOHO Interactive (Australia). “Sneaky Volcano” and “Evacuation Bingo” are two such games that were designed to educate students on the hazards associated with typhoons and volcanoes. Recently launched at the Science Centre Singapore for secondary school students, all seven games form the most entertaining part of the Dynamic Earth Workshop. Refreshments will be provided. There are two sessions, the first at 3pm and the second, at 4pm. Kindly register your attendance here.

USGS Near-real time Shaking & Loss Estimation: Challenges & Updates

USGS Near-real time Shaking & Loss Estimation: Challenges & Updates

Seminar
Speaker: David J Wald
Date: Fri, 2019-04-05 16:00 to 17:00
Venue: ASE 3D Visualisation Laboratory (N2-B1c-16c)

About the Event

USGS continues to further develop several near-real time earthquake information systems that provide rapid and automated alerting of shaking distribution, critical facility inspection priorities, and estimates of economic and human impacts following earthquakes.

We’ll describe the evolving research and development behind the components required to rapidly assess an earthquake’s impact: rapid faulting characterization, estimates of shaking distribution, losses estimates, and communicating uncertain loss estimates in an appropriate form for actionable decision-making among a variety of critical users. New products and efforts include 1) rapid estimates of earthquake-induced landsliding and liquefaction around the globe, 2) refactored ShakeMap, ShakeCast, and DYFI codes and functionality, 3) and a focus on incorporating of ground-truth observations for rapidly updating loss models.

In addition to the critical response users of these tools, loss-modellers, (re)insurers, governments and aid organizations use rapid earthquake information for loss estimation, situational awareness, and financial adjudication. Such financial tools can be a significant benefit to the at-risk public by facilitating risk transfer, fostering sensible management of portfolios, and assisting disaster response.

Topics to be introduced that could be flagged for follow-up discussions include: spatial interpolation and variability of ground shaking and implications for loss estimates, portfolio fragility functions and loss estimation (ShakeCast); the use of earthquake scenarios for planning and portfolio analyses; and the details of our empirical models of loss estimation, landslide and liquefaction assessment, among others.

Case Studies of Financial Decision-Making using Near–Real-time Post-Earthquake Information

Case Studies of Financial Decision-Making using Near–Real-time Post-Earthquake Information

Seminar
Speaker: David J Wald
Date: Tue, 2019-04-09 13:00 to 14:00
Venue: Lecture Theatre 19 (N2-B2A-01)

About the Event

In the immediate aftermath of a damaging earthquake, billions of dollars of relief, recovery, and insurance funds are in the balance through new financial instruments that allow those with resources to hedge against disasters and those at risk to limit their earthquake losses and receive funds for response and recovery. Many of these mechanisms, such as catastrophe bonds (catbonds), have come to rely on near-realtime (NRT; typically minutes to a few hours) earthquake information that allows those affected by the consequences of a disaster to quickly access financial capital. NRT products had been routinely used for situational awareness, to support response and facilitate aid, and as such they should also be of interest to those in the earthquake hazard and risk community. Such financial strategies can have significant benefit for stakeholders: They facilitate risk transfer, foster sensible management of risk portfolios, and assist in disaster response and recovery.

Yet, making funds available for at-risk populations also provides opportunities for investors who benefit from financial diversification. We will discuss the general categories of post-earthquake financial decision-making that benefit from detailed NRT earthquake hazard input: (1) Rapid damage assessments that guide disaster response and aid deployment; (2) estimation of monetary loss to a portfolio of industrial, commercial, or residential exposures to guide the claims adjustment process; and (3) the triggering of so-called parametric transactions—insurance instruments that rely on the physical measurement of event characteristics to determine if the insured party receives compensation and how much. In this presentation I will focus on the latter two categories.

Seminar
Plant-soil interactions, ecosystem functioning and global change

Plant-soil interactions, ecosystem functioning and global change

Seminar
Speaker: Richard Bardgett
Date: Fri, 2019-04-12 16:00 to 17:00
Venue: ASE 3D Visualisation Laboratory (N2-B1c-16c)

About the Event

Human activities are rapidly changing the world’s ecosystems. The most obvious human impact is through the conversion of land for agriculture, but terrestrial ecosystems are also affected by other global change phenomena, including climate change. This has led to a groundswell of research aimed at improving understanding of the impact of global changes on biodiversity and ecosystem function, and on management strategies to mitigate them. Whilst this topic has received much attention, scientists have only recently become aware that understanding the consequences of global change for ecosystem functioning requires consideration of interactions between plant and soil communities. This is because the impact of global changes on the functioning of terrestrial ecosystems is often indirect: they operate via changes aboveground that cascade belowground to the soil biological community, which drives biogeochemical processes and feedbacks to the Earth’s climate system. In this talk, I will highlight some recent developments in this area that illustrate how a combined aboveground–belowground approach can improve understanding of the consequences of global change for the functioning of terrestrial ecosystems. In particular, I will discuss recent research showing how plants influence the structure and functioning of complex belowground communities across different spatial scales, and how these interactions are modified by global change, especially climate extremes. Finally, I will consider how an improved understanding of ecological interactions between plants and belowground communities might be harnessed to meet sustainable management goals.



Richard Bardgett

Richard Bardgett is Professor of Ecology at The University of Manchester, United Kingdom. His main research interest is the study of plant-soil interactions and their impact on biogeochemical cycles and plant community dynamics, mostly in the context of global change. In particular, his research seeks to advance our understanding of the mechanisms by which complex soil biological communities influence ecosystem processes, and how plant functional diversity controls the structure and functioning of belowground communities at different temporal and spatial scales. His research also focusses on unravelling the mechanisms by which feedbacks between plant and soil communities regulate biogeochemical responses to climate change. He has written several books on these topics, including The Biology of Soil (2005), Aboveground-Belowground Interactions (with David Wardle) (2010), and Earth Matters: How Soil Underpins Civilization (2016), and is routinely recognized as a Highly Cited Researcher in ecology and environmental sciences. Richard is currently President of the British Ecological Society and Senior Editor of Journal of Ecology, and was elected an Honorary Fellow of the Royal Society of New Zealand in 2006, Fellow Royal Society of Biology in 2011, and a member of Academia Europaea in 2015.

A Talk in Two Parts: Overview of research to stimulate conversations and Insights into the evolution of a subduction-accretion system, southern Alaska

Seminar
Speaker: Elisabeth Nadin
Date: Fri, 2019-04-26 16:00 to 17:00
Venue: ASE 3D Visualisation Laboratory (N2-B1c-16c)

About the Event

The first half of the talk will focus on ongoing projects including: examining the strength evolution of a continental fault zone at the brittle-ductile transition; reconstructing an active arc volcano stratigraphy from eruption products; and determining wind patterns from detrital-zircon ages of loess deposits. The second half of the talk will focus on a brief tectonic history of southern Alaska, which includes accretion of a Jurassic arc followed by its two-part accretionary complex. A brittle-ductile fault within the accretionary complex gives insights into fault strength in a subduction-zone environment.
