Post-doc positions at Luleå University of Technology in Mining Seismicity and Seismic Hazard

Duties of the postdoctoral employment position:

A Post doctor will be involved in research within MRE, related to data analysis in order to define suitable proxies for stress changes and methodology for time-dependent seismic hazard in mines taking into account the stress changes, and to develop a tool for medium- to long-term-seismic hazard. The methodologies and tools will be applied on selected cases in Swedish mines.

Duties of the postdoctoral scholarship position:

We offer a stimulating and dynamic research environment with an extensive national and international network along with interesting, exciting research projects. A post doctor will have great freedom to define the own research activities and will be given the opportunity to present and discuss research results nationally and internationally.

Institute of Geophysics Polish Academy of Sciences presents workshop in Pretoria, South Africa

The Department of Geology and Natural Hazard Centre cordially invites you to a workshop. This course will introduce participants to the problem of seismicity associated with geo-resources exploitation. We will discuss different geo-resource exploitation technologies that may induce seismicity and the mechanisms of interaction between technological activity and the rock mass. We will determine the necessary conditions to identify earthquakes as induced, triggered, or natural. Participants will learn about the vital properties of anthropogenic seismicity. They will also learn what kind of scientific tools may be applied to assess the hazard they pose. Finally, they will learn about the international collaborative undertakings for research into anthropogenic seismicity. Additionally, the course will provide information concerning data typical for seismological studies in anthropogenic seismicity.

After the course, the participants will be familiar with seismic catalogues and seismic monitoring. We will discuss which information is included in a standard catalogue and how a catalogue can be used in seismic hazard analysis. Most of the below topics involve hands-on activities using the EPISODES platform EPOS Thematic Core Service Anthropogenic Hazards.

Space is limited and booking is essential: ansie.smit@up.ac.za

The workshop is co-financed by the program of the Minister of Education and Science of the Republic of Poland, "Supporting the participation of Polish research teams in international projects research infrastructure"

Seismicity Induced by Human Technological Activities and the Related Seismic Hazard

Seismicity induced by human technological activities can pose a severe hazard to people and infrastructure. Do you want to learn how to minimise these risks and support industrial activities in seismically active regions? Join exclusive two-day contact course on 25-26 May 2023 and get hands-on experience with the EPISODES platform. Enterprises University of Pretoria’s expert presenters will guide you through the different geo-resource exploitation technologies that may induce seismicity and the mechanisms of interaction between technological activity and the rock mass.

Induced Seismicity Workshop & Episodes Platform Training in Natal, Brazil

On February 2nd and 3rd, 2023, the representatives of EPOS Thematic Core Service Anthropogenic Hazards from the Institute of Geophysics Polish Academy of Sciences had the pleasure of holding the 1st 2023 EPOS TCS AH workshop at the Federal University of Rio Grande do Norte in Natal in Brazil. The workshop, hosted by the Seismological Lab, Department of Geophysics UFRN, was entitled "Seismicity induced by human technological activities and the related seismic hazard." The event grouped twenty-one participants with diverse experiences from four universities, the Geological Survey of Brazil, and the private sector (Veneto Consultoria em mineração, JMC - Yamana Gold, Braskem Bairros).

Activities within the framework of the workshop included introductory lectures and discussions on anthropogenic seismic processes and related hazards and risks. However, most of the workshop time took hands-on training on the EPISODES platform. By processing the data from the episodes available on the platform using software implemented there, the participants were solving predefined data analysis problems for anthropogenic seismic hazard assessment. At the same time, they learned about the platform's technical content and got to know how to work on it successfully.

The lectures and the training were held by Beata Orlecka-Sikora, Łukasz Rudziński, and Stan Lasocki, with the assistance of Helena Ciechowska (IG PAS) and the support of Aderson do Nascimento (UFRN).

The participants very well evaluated the workshop. The trainers were asked to consider repeating such a workshop as a side event of the geological conference in Rio de Janeiro in the fall of this year.

Invitation to the EPOS Data Portal launch

After over a decade in the making, the EPOS - European Plate Observing System Data Portal will be officially launched next month and presented at the European Geosciences Union - EGU.

Join us at the event on April 25, 19:00 CET

World Water Day with a Spotlight on Seismicity - Brazil

José A. S. Fonsêca (Ph.D. student at UFRN / Brazil) says: In Brazil, at the same time it concentrates the largest percentage of drinking water in the world, it is not exempted from geohazards such as induced earthquakes and risks of contamination. For instance, on the one hand triggered events have been already recorded with magnitudes as large as 4.2 mb in the past. On the other hand, in recent years a collapse of a tailing dam caused death of people and severe contamination of a watershed, whose recovery capacity is still a matter of debate. This draws not only attention to facilities stability but also to societal safety, once poorly built buildings are not rare, and the distribution of potable water is not equal. In this regard, the key word is “monitoring”. Once it is not possible to predict any occurrence of disaster, geohazard monitoring plays a paramount importance for intelligent water reservoirs usage. Measurements of humidity, soil vibration, displacements, spatial-temporal analysis, and many other observations help to increase the understanding of the problem, thus mitigating potential threats to society and environmental impacts.

World Water Day with a Spotlight on Seismicity - Greece

The critical role of water as a renewable energy source, via the operation of hydroelectric power, attracts also the attention of geohazard analysis due to the triggered seismicity caused by reservoir impoundment. In Greece, there is a number of hydroelectric power plant complexes located around the greatest rivers of the country amounting to about 9% of the total production of the Public Power Corporation, while the artificial lakes provide water for some large cities and support a healthy ecosystem. At the same time, reservoir impoundment is known to trigger seismic responses, usually in the form of weak and moderate magnitude earthquakes, but can be also related to the triggering of strong ones.

In 1966, immediately after the impoundment of the Kremasta lake, a destructive earthquake of M>6.0 occurred, leading to an intense aftershock activity in an area that was seismically active but had not experienced a M6.0 earthquake for over 200 years. Similarly, the reservoir impoundment of three lakes in the Aliakmonas river complex between 1974 and 1985 led to an increase of seismicity, and in 1995, an MS6.6 earthquake occurred about 20 km away from the Polyphyto dam in an area of historically low seismicity rates, that had not experienced such a magnitude for centuries. Both earthquakes led to loss of life and thousands of destroyed or severely damaged houses and infrastructure. Cases like those highlight the fine balance between the benefits of clean hydropower energy and geohazard risk management when working towards a sustainable and environmentally responsible energy future.
