ELEVATED MICROSEISMIC ACTIVITY DURING THE SEPTEMBER FLOODING
Abstract
During the floods in September 2010 that affected Slovenia, an increased seismic disturbance in the frequency range between 0.25 Hz and 1 Hz was observed on the seismic network of Slovenia. Because this phenomena coincided with floods it has been analysed in detail. The phenomena can be described as secondary macroseismic activity generated by the undulation of the Adriatic Sea in the Gulf of Trieste. The rolling was a result of the warm front. Such local secondary macroseismic activity can be a useful and a free-of-charge source of seismic signal for the analysis of seismic vulnerability of certain facilities despite being limited in time and frequency and spatially focused.
