This free webinar, featuring two Geoscientists without Borders® (GWB) humanitarian projects, provides information about how these projects are helping to increase resiliency to geologic hazards in Guatemala and improving potable water access and supply for communities in northeastern Ghana. By helping these communities address their challenges, these GWB projects are helping to invest in the planet. Our speakers are Steven L. Roche, Co-Investigator, Hearts in Motion, and Elikplim Abla Dzikunoo, Lecturer, Department of Earth Science, University of Ghana.

About the speakers

Increasing Natural Hazard Resiliency in Guatemala

Steven L. Roche, Co-Investigator, Hearts in Motion, will discuss the GWB project, Increasing Natural Hazard Resiliency in Guatemala, which aims to increase the geohazard resiliency and safety of the communities in Guatemala through implementing community-based educational workshops about earthquake and volcanic hazards, increasing Instituto Nacional de Sismología, Vulcanología, Meteorología e Hidrología (INSIVUMEH)'s seismic and volcanic monitoring capacity, and reducing disaster response time by using the implementation of a regional seismic array consisting of low-cost "Raspberry Shake" 3C seismometer stations in Zacapa near the Motagua-Polochic fault system and significantly improve INSIVUMEH's earthquake and volcanic monitoring infrastructure including Early Warning Systems (EWS).

Provision of potable water to communities in northeastern Ghana

Elikplim Abla Dzikunoo, Lecturer, Department of Earth Science, University of Ghana, will discuss the GWB project, Provision of potable water to communities in northeastern Ghana, which aims to improve potable water access and supply for the benefit and socio-economic wellbeing of inhabitants based on scientific data and recommendation on sustainable exploitation, development, and management of groundwater resources in areas within the Nasia river basin, northeastern Ghana. This was done by using Electrical Resistivity Tomography techniques to define and interpret geo-electric sections and models to show the subsurface lithology distribution, and provide scientific data that will inform groundwater management policy decision making and improve access to potable water resources by the communities of study area.To build on the knowledge of the areas geology and offer a better understanding of the underlying complexities, lithologic logging was done during drilling followed by geophysical logging after drilling which offer improved resolutions of the subsurface geologic complexities.

Geological Survey Organizations (GSOs) play a critical role in understanding geo-hazards and risks as a required component for designing and implementing disaster risk management policies and programs. This forum will provide three virtual workshops to support the exchange of information among executives and senior managers on the role of GSOs in Disaster Risk Reduction (DRR) at a National Level. The forum will provide a high level overview of the role of GSOs in disaster risk reduction, including strategies, awareness of and advocacy on hazards and risks, financial risk management, building codes, and early warning systems.

The forum will also provide an overview of the range of national interinstitutional governance structures within which GSOs function, in the context of national level DRR and climate change adaptation policy settings. Speakers will discuss the common challenges and opportunities for effective use of hazard and risk assessments in national DRR policies, investments, and programs, identify gaps and enablers for enhancing the role of GSOs in DRR, and evaluate how the focus and investments in climate adaptation can be a threat but also an opportunity for enhancing geo-risk awareness and resilience measures.

The forum will be hosted as a set of three regional sessions, with each regional forum featuring pre-recorded lectures from science policy experts and geoscientists and a live moderated discussion session with attendees.

All sessions will be conducted in English with live captioning in French, Spanish, Portuguese, Russian, Modern Chinese, and Arabic.

About our speakers:

Václav Kuna (*1988) works as a postdoctoral researcher at the at the Institute of Geophysics of the Czech Academy of Sciences, Prague, Czech Republic since September 2020. He received his Ph.D. degree in seismology at Oregon State University in Oregon, USA, studying seismicity and tectonics of the Blanco Transform Fault Zone in the northeast Pacific Ocean using seismometers placed at the ocean bottom around the fault. During the Ph.D. studies, Vaclav has participated in several large-scale broadband seismic experiments in the Caucasus mountain range and Himalayas and was part of a team monitoring aftershock seismicity after the M7.8 earthquake in Nepal in April 2015. This experience steered his scientific interest away from a purely academic seismological career towards more mission-driven science. At the Institute of Geophysics, Vaclav studies novel, low-cost Earthquake Early Warning systems based on IoT (Internet of Things) principle. He wants to test the feasibility of such a system in central Nepal to help to reduce the extreme seismic risks in the region.

Thomas Oommen is a Professor in the Geological Engineering department and the Director of the Computational Science and Engineering Ph.D. Program at Michigan Technological University. He is actively involved in undergraduate and graduate education, research, and service. He teaches the engineering geology course at Michigan Tech, has participated in over $7 million in research grants, and published over 70 peer-reviewed journal articles. His research focuses on utilizing remotely sensed data, machine learning algorithms, and geological knowledge to solve real-world problems that affect human health and safety. Beyond Michigan Tech, he serves as the chair of the editorial advisory board of the GSA and AEG joint publication Environmental & Engineering Geoscience, chair for the Environmental and Engineering Geology division of GSA, vice-chair of the ASCE Geoinstitute Engineering Geology and Site Characterization Committee, a member of the AEG technical committee on landslides, and a member of the AGU Natural Hazards awards committee.

Additional Questions & Answers from the webinar

Download Questions & Answers

How are you planning to provide power and internet to stations in the mountains?
Power via electric gridline is available in the mountainous regions where we are planning to deploy our sensors. We plan to use wifi/ethernet connection that uses cellular internet available in the region. However, we need to test the stability of both the internet and power connections. Future versions of the seismic sensor will be equipped with a solar panel, battery, and cellular internet connectivity so they can be more standalone in regions like this one.

I'm interested to learn more about the dead zone around the epicenter. In Utah, 85% of our population lives on top of the Wasatch Fault (large normal faults related to extension).
The earthquake early warning system takes roughly 10 seconds since the earthquake origin time to characterize the earthquake. This includes the travel time of earthquake primary waves from the hypocenter to closest stations, data transmission to server, data processing etc. At the time of 10 sec since the earthquake origin, damaging secondary waves will have already reached a region within about 40 km radius around the earthquake epicenter. Therefore, that region cannot receive the alert in time and the EEW system may help only in regions farther away from the earthquake epicenter.

What is the cost of the sensors?
The sensor is now manufactured by Grillo, Inc. and the price is a few hundred dollars (particular price depends on the type of enclosure, sensor with/without gps etc). The sensor design is open-source and published on github (https://github.com/openeew/openeew-sensor) so anyone can manufacture it themselves. In that case the total cost will largely result from the cost of individual components, which depends on the ordered quantity and other factors.

Would one potentially be able to use these types of earthquake sensors to detect earthquake events or submarine landslides and thus create an early warning system for local tsunamis originating very close to shore?
Unfortunately, I am not familiar with seismic signals of submarine landslides. The sensor needs to be deployed on land and cannot be used as an underwater sensor. On land, it can capture accelerations greater than about 40 micro-g. If underwater landslides create signals stronger than this threshold, the system can potentially work for the job. However, new processing methodology would have to be developed/adopted for this specific application.

Can we link Direct push with Electrical Resistivity Tomography (ERT) surveys for landslide studies?
We don't have direct push data for our study region. However, if you have both direct push and ERT data, it will be an exciting link to make.

Are you also using water gauge stations on the different rivers?
We are using groundwater well information.

Would it be practical to use the USDA soil profile (websoil/) in slope susceptibility analysis?
That will be something to explore. However, the question is whether USDA data has sufficient spatial resolution to perform slope stability analysis. Combining USDA data with some geophysical surveys can be promising.

The need for having sustainable water is a key element in global resilience to climate change, as a shield against ecosystem loss, and as a defense against human deprivation and poverty. Water is essential to the health of all living things. With the onslaught of climate change, drought and exploding population growth, water is a valuable but very vulnerable resource. Water can be an element of peace, supporting security and abundance, or a source of transboundary conflict fueling political ambitions.

Groundwater, in particular, is the underpinning of irrigated agriculture and energy production and it therefore supports food security and economic development. Groundwater provides drinking water to at least 50% of the global population, and worldwide, approximately 2.5 billion people depend solely on groundwater resources to satisfy their basic daily water needs (UNESCO, 2012). In these times of Covid-19, groundwater also promotes hand washing in isolated rural communities. But it is a hidden resource and not well understood.

Examples from around the nation and world illustrate the importance, vulnerability, and changing aspects of water quantity and quality. Some potential solutions and stopgap measures are on the horizon to preserve our water resources, but the challenges are immense.

The number of refugees and internally displaced persons (IDPs), worldwide, is about 80 million. Most refugees are fleeing water-stressed and conflict-torn countries such as South Sudan, Somalia, and Syria. Generally, the host countries for refugee populations are also arid or semi-arid, such as Kenya, Chad, and Jordan. In the marginal landscapes where refugee camps are usually sited, groundwater is often the only practical source of water for drinking, cooking, and sanitation. A lack of access to adequate water supplies is directly tied to increasing occurrences of cholera, dysentery, hepatitis, trachoma, and other diseases. Today, with Covid-19 outbreaks already occurring in overcrowded refugee camps, improving hygiene is critical. A well-targeted geophysical exploration program can make the difference between a successful water supply program and one doomed to failure.

In this talk, I lead you on the geophysical search and then the discovery of water in a few of the refugee camps and conflict zones in East Africa. In each of these settings, the cause of human displacement is distinct, the geology and hydrogeology vary, the landscapes are strikingly different, but the need for water is equally desperate.

In one of the largest refugee camps in the world, in the Turkana desert of Kenya, seismic and resistivity surveys helped to increase the water supply to the camp and, simultaneously, a previously unrecognized public health crisis was addressed. In Northern Uganda, in the devastation left behind by Joseph Kony and the Lord’s Resistance Army, village water supplies were restored following geophysical surveys and hydrochemical testing. More importantly, the local Ugandan crews were trained to carry on with this technical work. Finally, in the midst of a civil war in the world’s newest country, South Sudan, an emergency mission relying on resistivity surveys took advantage of a cessation of hostilities to find water in villages stranded by the conflict.

Cave research represents the essence of Earth science since it involves going into and directly studying the Earth itself. Caves, and the karst areas in which most form, are highly valuable yet vulnerable features. They provide water to about 700 million people but are the most easily contaminated of groundwater supplies. Additionally, they can collapse to create sinkholes, swallowing roads and buildings, causing hundreds of millions of dollars in damages annually in the US alone. Join this presentation, which is part of the celebration of the International Year of Caves and Karst, to explore caves and karst around the world and the many aspects of the Earth sciences they include.

Geological Survey Organizations (GSOs) have been helping society face economic and environmental challenges for over 150 years. The technological transformation of geoscience is presenting new opportunities for GSOs, and the wider geoscience community, to respond to the societal challenges of our time, and lay the foundation for a sustainable future. Three-dimensional geological modelling is providing a valuable tool for informed decision making and risk reduction – from planning urban infrastructure, managing ground water resources, and sourcing renewable energy. To capitalize on this capability, new data infrastructures are required to share and integrate information across government and the private sector.

This two-part webinar will feature leaders in the field, presenting the latest developments, and will be of interest to students, academics, private sector practitioners, and other government agencies.

This webinar series is sponsored by the World Community of Geological Surveys (WCOGS).

Background

Two related developments have moved the use of radar imagery into the operational realm. The supply of available data has increased greatly, especially with the freely-available Sentinel-1 satellites. And the analysis algorithms are now tested and established, producing reliable and standardized Information Products. One application in particular has benefited greatly from these synergistic developments; centimeter-scale measurement of surface motion on a regional scale. The ability to produce time-series displacement maps with a high point density has revolutionized the monitoring, and mitigation, of subsidence due to subsurface extraction of resources such as water or hydrocarbons.
