"Geomorphic expression of neotectonic activity in a low relief area in an Airborne Laser Scanning DTM: A case study of the Little Hungarian Plain (Pannonian basin)";

English abstract:
The NW corner of the Little Hungarian Plain, which lies at the junction of
the Eastern Alps, the Pannonian Basin and the Western Carpathians, is a
neotectonically active region linking the extrusional tectonics of the
Eastern Alps with the partly subsiding Little Hungarian Plain. The
on-going deformation is verified by the earthquake activity in the region.
An extremely flat part of the area, east of Neusiedlersee, the so-called
Seewinkel, has been investigated with Airborne Laser Scanning (ALS, also
known as airborne LiDAR) techniques, resulting in a digital terrain model
(DTM) with a 1 m grid resolution and vertical precision of better than 10
cm. The DTM has been compared with known and inferred neotectonic

Potential neotectonic structures of the DTM have been evaluated, together
with geological maps, regional tectono-geomorphic studies, geophysical
data, earthquake foci, as well as geomorphological features and the
Quaternary sediment thickness values of the Seewinkel and the adjacent
Parndorfer plateau. A combined evaluation of these data allows several
tectonic features with a relief of < 2 m to be recognized in the DTM. The
length of these linear geomorphological structures ranges from several
hundred meters up to several kilometers. The most prominent feature forms
a 15 km long, linear, 2 m high NE-SW trending ridge with gravel
occurrences having an average grain size of ca. 5 cm on its top. We
conclude this feature to represent the surface expression of the
previously recognized Mönchhof Fault. In general, this multi-disciplinary
case study shows that ALS DTMs are extremely important for
tectono-geomorphic investigations, as they can detect and accurately
locate neotectonic structures, especially in low-relief areas.
