Geology Open Night
Spring 1999 Offerings
The Department of Geosciences SUNY Stony Brook
Presents
Geology Open Night
Open night lectures are usually on topics in the geosciences
related to the current research of the faculty, staff and students at SUNY
Stony Brook. These presentations are intended for:
those interested in new developments in the sciences
earth science high school students and teachers
undergraduate and graduate students in geosciences
professional geologists on Long Island

"Whose Fault is it?
Why the Earth Quakes"
Prof.
Donald Weidner
Department of Geosciences
SUNY Stony Brook
7:30 - 8:30 p.m. Friday January 29, 1999
Earthquakes are a constant reminder of the natural forces shaping our
planet. They mostly occur in the shallow crust, but many occur to depths
of 700 kilometers. Their very existence informs us about the processes
occurring within the Earth as well as about the properties of the rocks
that catastrophically fail under load. We will explore the history of man's
understanding of these violent acts of nature, from the early Japanese
model of the giant catfish to our modern view of frictional sliding on
a fault. Still, we do not understand the process for deep events. We will
look at recent research results that attempt to understand why these deep
earthquakes do occur.

"Volcanoes:
Windows into the Earth's Crust and Mantle"
7:30 - 8:30 p.m. Friday February 26, 1999
Volcanic eruptions provide awe-inspiring demonstrations
of the power of the processes at work within the Earth. They also provide
invaluable information about the thermal and compositional structure of
the Earth's crust and upper mantle. Through ongoing theoretical, experimental,
and field observations, petrologists are determining the characteristics
of silicate melts and the critical variables that lead to the diversity
in eruptive styles and eruption products that characterize volcanoes world-wide.
Such information, when combined with data on the tectonic histories of
volcanic provinces provides invaluable insights into the dynamic state
of the Earth.
Facing the Beach
7:30 - 8:30 p.m.
Friday Mar. 26, 1999
When we turn towards the beach we might be looking for a gratifying
panorama, a dip in the surf or maybe just a tan. But, living on an island,
we also must face a variety of choices demanded by the uncertainty of a
mobile beach. What causes the problem of coastal erosion? What do we want
our beaches to be? How can we cope with the choices that our grandparents
made that still affect the shoreline today? Which conflicting uses must
be accommodated and which can we tolerate? And how much will it cost? We
will talk about the processes that shape the shoreline and influence our
decisions, and the shape of things to come. The "problem" of coastal erosion
may not be what you think.
