Poster on Haiti earthquake

The recent earthquake at Haiti is very much in the news, more for the unprecedented devastation and death toll.  From the scientific point of view, this earthquake could be cited as the closest the scientific community has succeeded in identifying a specific fault where earthquake is imminent, and also estimate its magnitude. This was mostly possible by the extensive GPS-based data and models of slip partitioning and deficit on the specific fault, which the seismologists considered, ready for an earthquake any day.
Two of our PhD students at the Centre for Earth Sciences have put together the background of this earthquake in the form of a poster. We thought this might be of interest to all of you.

We will appreciate your comments

Workshop on ‘Tracking the Anthropocene and Beyond: an Earth System Science Approach to Evaluate the Impacts and Implications of Human forcing’

Sponsored by the Department of Science and Technology (DST), New Delhi.

Venue: Golden Jubilee Seminar Hall, Civil Engineering
20.9.2008, 9:30 AM to 4:30 PM

We are organizing a DST funded, one-day workshop on tracking the markers of the Anthropocene, with an objective of formulating a multidisciplinary project.  The goal of the workshop is to discuss viable themes that can be taken up as part of this proposal. Various themes being proposed by the participants from CEaS, CES, CAOS and Civil Engineering as well as other universities and organizations give a multidisciplinary character to this program, which takes an Earth System Science approach in evaluating the changes in the eco, hydro and geospheres during the last few hundred to few thousand years.

Some specific issues to be addressed are: (1) can the stratigraphic boundaries signaling the human forcing be identified and characterized? (2) what are the tangible biotic, sedimentary, geochemical and geophysical signatures that can be used to define and characterize this boundary? (3) which are the potential type areas and the techniques to be followed and (4) how best can these observations be used to infer past environmental (including climate) conditions and to develop models for future. The workshop is expected to bring together experts in the fields of earth and climate sciences, ecology and archaeology.
