Welcome to my homepage!

This page is dedicated to share with you some information about my professional activity. I am a geologist. I work as a researcher-lecturer and Gamma Lab manager at the Institute of Geology, Adam Mickiewicz University in Poznan, Poland. 
I am interested mainly in modern geological processes, in particular those which pose a threat to people. On this webpage I present some information about the work I am involved in. So, you may find some published results, information about my projects, laboratories and teaching materials for students.
I hope that You will find something interesting here. Enjoy!

The results of 5 years monitoring of tsunami deposits left by the 2004 Indian Ocean Tsunami were recently published as open access paper in Natural Hazards journal
see: http://www.springerlink.com/content/h2kp22825gv80051/

 

The preservation potential and the post-depositional changes of the onshore tsunami deposits in the coastal plain setting, under conditions of a tropical climate with high seasonal rainfall, were assessed by reinvestigating trenches located along 13 shore-perpendicular transects; the trenches were documented shortly after the tsunami and after 1, 2, 3 and 4 years. The tsunami deposits were found preserved after 4 years at only half of the studied sites. In about 30% of the sites, the tsunami deposits were not preserved due to human activity; in a further 20% of the sites, the thin tsunami deposits were eroded or not recognised due to new soil formation.

The most significant changes took place during the first rainy season (see figure) when the relief of the tsunami deposits was levelled; moderate sediment redeposition took place, and fine surface sediments were washed away, which frequently left a residual layer of coarse sand and gravel. The fast recovery of new plant cover stabilised the tsunami deposits and protected them against further remobilisation during the subsequent years.

After five rainy seasons, tsunami deposits with a thickness of at least a few centimetres were relatively well preserved; however, their internal structures were often significantly blurred by roots and animal bioturbation. A comparison between the first post-tsunami survey and the preserved record suggests that tsunamis with a run-up smaller than three metres are not likely to be preserved; for larger tsunamis, only about 50% of their inundation area is likely to be presented by the preserved extent of the tsunami deposits.

The first results of UNESCO International Tsunami Survey Team (ITST) work in areas hit by 11th March 2011 tsunami in Japan are already available!

 

In May 2011 the geological ITST composed of scientists from Japan, USA, Australia, UK, Indonesia and Poland (see photo) surveyed areas nearby Sendai where tsunami inundated as far as 4.5 km inland. The first results are available as a report for UNESCO and local communities in English (pdf) and Japanese (pdf). Moreover the description of the survey is published in USGS newsletter “Sound Waves” (pdf).
