Field work in the Lake Elmenteita basin, Central Kenya Rift
In July 2022, Veronica Muiruri, Dickson Nyonje
(both National Museums of Kenya, Nairobi),
Annett Junginger, Carolina Rosca (both
University of Tübingen), and myself had the
opportunity to carry out a field campaign in
the Lake Elmenteita basin in the Central
Kenya Rift. Objectives for field work were to
sample lake sediments, rocks, soils and water
to examine the interplay between geotectonic,
climatic and anthropogenic influences on
lacustrine deposition processes, lake level
fluctuations and pollution in this highly
sensitive lake system. Field work was
financed by the Bavarian Research Alliance
(BayFor), and the University of Tübingen
(postdoc excellence fund).

ICDP kick-off workshop on "Deep Drilling in the Turkana Basin (DDTB), Nairobi, July 11-14 2022
Nairobi, July 11-14 2022
The workshop hosted an international group of scientists with the aim to discuss a drilling campaign to recover the Plio-Pleistocene paleoenvironmental record of the Turkana Basin (N-Kenya and S-Ethiopia).
International Conference on "Aegean Acheulean at the Eurasian Crossroads"
Lesbos, June 25-29 2022
The international conference was organized
by the University of Crete and hosted a range
of scientists in the fields of archeology,
geology and paleoclimate.
Interview with BBC Earth on "The volcano that drives the Great Wildebeest Migration"
BBC Earth, November 2021
I had the chance at BBC Earth to talk
about the role of Ol Doinyo Lengai
volcano in northern Tanzania, and its
carbonatitic volcanic ash in providing nutrients
for soils and animals in the Serengeti ecosystem.
The study is based on results obtained during
our 2019 field campaign, in collaboration with
Eileen Eckmeier (University of Kiel),
Stephen Rucina (NMK, Nairobi), and
Akida Meya (NM-AIST, Arusha, Tanzania).

Lithological and Topographic Impact on Soil Nutrient Distributions in Tectonic Landscapes: Implications for Pleistocene Human-Landscape Interactions in the Southern Kenya Rift
Frontiers in Earth Science, March 2021
In this study, we analyze the role of
geological processes in the distributions
of soil nutrients in the southern Kenya Rift,
a key region in the interpretation of early
human-landscape interactions. Our aim is
to determine how spatial variations in rock
chemistry, as well as topographic gradients
and localized zones of rock fracturing from
tectonic faulting determine the distributions
of plant-available soil nutrients in soils. We hypothesize that present-day soil nutrient levels reflect the long-term chemical and geomorphological characteristics of the landscape and underlying parent material, and that regions with high nutrient availability occur along pathways correlating with locations of hominin fossil sites.

Our aim in this paper is to examine the reconstruction of physical landscapes in rift settings and their relevance to archaeological interpretation and to reflect on the challenges and opportunities of such research, with particular reference to the Kenyan sector of the East African Rift.

Field work in Serengeti National Park, N-Tanzania
In Sep/Oct 2019 Eileen Eckmeier (University of Munich, Geography), Stephen Rucina (National Museums of Kenya, Nairobi), Akida Meyr (Nelson Mandela African Institute of Science and Technology, Arusha, Tanzania) and myself had the opportunity to carry out a two-weeks field trip to the famous Serengeti National Park in Northern Tanzania. Objectives for field work were to carry out reconnaissance mapping and locate potential sampling locations for rocks, soils and vegetation to examine geological and pedological processes that might play an important role in controlling annual movements of wildebeest and other migratory species in this ecosystem.

Tectonic Geomorphology and Soil Edaphics as Controls on Animal Migrations and Human Dispersal Patterns
In: Geological Setting, Paleoenvironment and Archeology of the Read Sea (eds.; N. Rasul & C. Stewart), Jan 2019
This chapter examines the relationship between the
changing geomorphology of physical land forms in
tectonically and volcanically active regions, topography, soil nutrients, movements of large mammals, and patterns of human subsistence and dispersal in the early stages of human evolution.
We show how the combination of topographic and soil-edaphic mapping in conjunction with the observed locations of stone-tool or fossil assemblages can highlight patterns of early human behaviour, using examples from the East African and Jordanian Rifts and the Arabian margin of the Red Sea.

In an exposure excavated across the Schafberg fault in the southwestern Lower Rhine Graben, south of Untermaubach, in the epicentral region of the 1756 Düren earthquake (ML 6.2), we mapped a complex deformation zone in Holocene fluvial sediments. We document evidence for at least one paleoearthquake that resulted in vertical surface displacement of 1.2 ± 0.2 m. The most recent earthquake is constrained to have occurred after 815 AD, and we cannot rule out that this fault acted as the source of the 1756 Düren event.
New Book of the Geological Society of London
edited by A. Landgraf, S. Kübler, E. Hintersberger, and S. Stein, entitled: Seismicity, Fault Rupture and Earthquake Hazards in Slowly Deforming Regions
This book explores challenging issues of characterizing earthquake occurrence and assessing the resulting hazards in slowly deforming regions. It combines seismological, palaeoseismic, geomorphological, and structural investigations from intraplate settings and diffuse plate boundaries. The resulting views provide insight into the physical processes involved, which might help to improve earthquake hazard estimation. Buy book or get papers online! The introduction is open access!

Apparent Late Quaternary Fault‐Slip Rate Increase in the Southern Lower Rhine Graben, Central Europe.
Bulletin of the Seismological Society of America, January 2017
In this investigation, we construct Quaternary slip histories for the southern Lower Rhine graben faults using new main terrace surface vertical offset measurements made from light detection and ranging (lidar)‐derived bare‐earth digital terrain models, which we synthesize with existing constraints on the offset basal contact of this fluvial deposit.
