Pernik Earthquake: an earthquake of magnitude 5.8 hit Western Bulgaria, on May 22nd, 2012, 25km south west of the Bulgarian capital, Sofia. This shallow earthquake was largely felt in the region and up to Greece and Macedonia. No severe injuries have been reported so far, though a state of emergency was declared in Pernik (the closest city to the epicenter) and superficial damages were observed ... more

Dipl. Eng. Petar Vulchev provided a copy of his GEORADAR equipment to the Geoteam at the Faculty of Physics and Engineering Technologies of Plovdiv University 'Paisiy Hilendarski'. The team will examine the potential of the equipment to be applied for studying the shallow crust. Find details here ... 


          

 

The GeoTEAM at Plovdiv University is working as part of the Faculty of Physics. Its research activity is focused mainly on stochastic modeling of seismicity, non-linear features of complex systems, site effects characteristics (mainly the application of the H/V spectral ratio technique) etc.

Plovdiv University, named in honor of the Bulgarian historian Paisiy Hilendarski, is the city’s leading cultural and scientific institution. It is the largest institution of higher education in Southern Bulgaria, and the second largest Bulgarian university, after St. Kliment Ohridski University of Sofia. The year 2001 marks the university’s fortieth anniversary.

Plovdiv is the second largest city in Bulgaria and the largest administrative, economic, cultural and scientific center in Southern Bulgaria. It was founded in the 2nd millennium BC as a Thracian settlement, and has centuries-old cultural and archaeological heritage. The city which is much older than Athens or Rome, treasures its architectural artifacts located in its Old Town. The unique Renaissance atmosphere of Old Plovdiv charms visitors to the city, and the seven hills on which this part of the city is situated, have their own special charisma.
