Solid Earth Dynamics
Critical to our understanding the Earth is knowledge of the physical processes that shape the Earth’s
formation, evolution, and present-day dynamics. The combination of state-of-the-art geophysical in-
strumentation and advanced computational capabilities makes it possible to observe and quantitatively
model complex geological systems in ways that were previously unimaginable. Research applications of
these geophysical methods include global tectonics, earthquake seismology, volcanology, structural ge-
ology, tectonic geomorphology, and environmental and exploration geophysics. Advances in quantitative
geochronology, thermochronology, and petrology have expanded the scope for interdisciplinary investi-
gation of deep Earth and surface processes involved in crustal deformation, sedimentary basin formation,
magmatism, landscape evolution, and natural hazard mitigation.

the devastating impact of a major natural disaster
— the magnitude 9.0 Tohoku (Japan) earthquake
and tsunami. Their artistic collaboration, which they
refer to as “Seismophotography,” was part of the IU’s
Grunwald Gallery exhibition, “Imag(in)ing Science,”
in 2013. Several pieces from that exhibition were ac-
cepted for a prestigious international photographic
exhibition. The Noorderlicht Photofestival, based in
Groningen, Netherlands opened in October of 2017,
and featured six of the pieces created by Nakagawa
and Hamburger for the exhibition.

modified the photographs using a number
of traditional recording techniques that have been used
by seismologists for over a century: smoke-paper and
ink-pen recording of current seismic activity on rotating
seismograph drums. They also experimented with man-
ual tracing of specialized engineering recordings from
“strong-motion seismographs” positioned close to the
location of the photographic images. These techniques
produced a new medium, “seismophotography”: images
that bring together photographic and seismological im-
pressions of dynamic Earth activity. The combination of
