Introduction
Philippe Roth currently works at the Swiss Seismological Service, Department of Earth Sciences, ETH Zurich. Philippe does research in seismic hazard and risk from natural and induced seismicity. Mineralogy is a leisure time activity (e.g. project 'Mineralogy of the Lengenbach Quarry, Switzerland.)'

Understanding seismic risk at both the national and sub-national level is essential for devising effective strategies and interventions aimed at its mitigation. The Earthquake Risk Model of Switzerland (ERM-CH23), released in early 2023, is the culmination of a multidisciplinary effort aiming to achieve for the first time a comprehensive assessment...
Successful carbon injection operations depend critically on the management of risks, like induced seismicity. Here, we consider the bowtie risk management framework to organize pre-screening efforts around a prospective CO2 injection operation near Trüllikon, Switzerland. First, potential barriers/threats are appraised via a literature review of th...
Exposure models for regional seismic risk assessment often place assets at the centroids of administrative units for which data are available. At best, a top-down approach is followed, where such data are spatially disaggregated over a denser spatial grid, using proxy datasets such as the distribution of population or the density of night-time ligh...

Scientists from different disciplines at ETH Zurich are developing a dynamic, harmonised, and user-centred earthquake risk framework for Switzerland, relying on a continuously evolving earthquake catalogue generated by the Swiss Seismological Service (SED) using the national seismic networks. This framework uses all available information to assess...
The new mineral heimite (IMA2022-019), PbCu2(AsO4)(OH)3 ⋅ 2H2O, was found at the Grosses Chalttal deposit, Mürtschenalp district, Glarus, Switzerland, where it occurs as a secondary mineral associated mainly with bayldonite and chrysocolla. Heimite forms lath-like, prismatic transparent crystals of green or pale-blue colour. It has a pale-green str...
With seismic risk assessments becoming more available and reliable over the
last years, the need to communicate seismic risk emerged. Seismic risk allows
people to understand what impacts earthquakes can have and how they could
affect their lives. In Switzerland, a nation-wide seismic risk model (ERM-CH23)
was published in 2023 demanding sophistica...

Argentotetrahedrite-(Zn), Ag6(Cu4Zn2)Sb4S13, has been approved as a new mineral species by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association (CNMNC-IMA) using samples from Kremnica, Slovak Republic (hereafter KR), and Lengenbach, Switzerland (LE). Additionally, it was also identified at t...
Tennantite-(Hg), Cu 6 (Cu 4 Hg 2 )As 4 S 13 , was approved as a new mineral species (IMA2020-063) from the Lengenbach quarry, Imfeld, Binn Valley, Canton Valais, Switzerland. It was identified as an aggregate of black metallic tetrahedral crystals, less than 0.1 mm in size, intimately associated with sinnerite, and grown on realgar. In reflected li...
The Swiss Seismological Service at ETH Zurich (SED, www.seismo.ethz.ch) wants to contribute to the sustainable and safe use of deep geothermal energy with this report on good-practice on monitoring, assessment and management of induced seismicity related to the exploitation of deep geothermal energy. The report is aimed at a range of audiences:
– f...
The new mineral species rüdlingerite, ideally Mn2+2V5+As5+O7·2H2O occurs in the Fianel mine, in Val Ferrera, Grisons, Switzerland, a small Alpine metamorphic Mn deposit. It is associated with ansermetite and Fe oxyhydroxide in thin fractures in Triassic dolomitic marbles. Rüdlingerite was also found on specimens recovered from the dump of the Valle...
The crystal structure of pyrostilpnite from the Plaka mine, Lavrion Mining District, Greece, was refined in the space group P 2 1 / c to a final R 1 index of 0.0283 on the basis of 2047 reflections with F o > 4σ( F o ) and 65 refined parameters. Unit-cell parameters of the crystal examined are a = 6.8629(6), b = 15.8800(14), c = 6.2711(5) Å, β = 11...
New discoveries in the Malcantone region, a small antimony mining district in Tessin with a history of sporadic ore extraction, include pyrostilpnite, owyheeite and "freibergite" from Miglieglia, the former two being new mentions for Switzerland, senandorite and semseyite from Aranno, again new for the country, as well as spectacular kermesite, jam...
The new mineral species hydrokenopyrochlore, ideallyA(0,#)2BNb2XO6·YH2O, has been discovered in the Antandrokomby pegmatite, Sahatany Pegmatite Field, Antananarivo Province, Madagascar. It occurs as tan to beige subhedral crystals, up to 1 mm in size, with a resinous luster, associated with quartz, tourmaline, orthoclase, Li-bearing mica, hübnerite...
The Lengenbach quarry is a world-famous mineral locality, especially known for its rare and well-crystallized Tl, Pb, Ag, and Cu bearing sulfosalts. As of June 2018, it is the type locality for 44 different mineral species, making it one of the most prolific localities worldwide. A total of 33 thallium mineral species have been identified, 23 of wh...

The new mineral species richardsollyite, TlPbAsS 3, was discovered in the Lengenbach quarry, Imfeld, Binn Valley, Canton Valais, Switzerland, intimately associated with hutchinsonite and baryte. It occurs as grey-black crystals, up to 750 μm, with a metallic lustre. Under the reflected-light microscope, richardsollyite is grey, with bright-red inte...
The St. Gallen Fault Zone (SFZ) is a system of major NNE–SSW striking normal faults within the North Alpine Foreland Basin (NAFB), just west of the city of St. Gallen. It used to be only roughly known from 2D seismic data, locally displaying offsets of up to 300 m at the level of the Mesozoic strata. We present a detailed structural interpretation...

The Lengenbach deposit has been famous among scientists and mineral collectors since the early nineteenth century. As the type locality for 31 new mineral species, the Lengenbach quarry ranks among the ten most prolific localities worldwide. But, unlike all the others, the mineralized body is small and has only been mined for scientific and collect...
Tremolite, Ca2(Mg,Fe)5Si8O22(OH)2, is a calcic amphibole commonly found in greenschist-facies to amphibolite-facies calc-silicate and in low-grade ultrabasic rocks. In the new IMA nomenclature of amphiboles (Leake et al., 1997) tremolite forms part of the tremolite-actinolite-ferro-actinolite series: Whereas usually the dividing line between two sp...
One of the most striking features revealed by a regional study of seismic activity in the eastern part of the Swiss Alps, conducted with a dense network of seismic stations between 1986 and 1988, is the restricted, around 13 km vertical extension of the seismogenic zone (defined by approximately 300 located earthquakes) compared with the earthquake...
The recent occurrence (end of 1953) of the thermal springs of Val d'Illiez, Wallis, is linked to exceptional events. During this year indeed, numerous seismic events were felt by the local population. These springs, located on the left bank of the Vieze River, outflow from Tertiary flysch of the Helvetic domain. The authors present an hypothesis ba...
