The paper is intended as an analysis of particle velocity generated during rockbursts in deep coal mines in the Ostrava-Karviná Coal Basin (OKCB), which are recorded at five underground seismic stations. On the other hand, we realized field measurem

In mid-January 2007 and at the turn of February and March 2008, two extremely strong windstorms, i.e. Kyrill and Emma, hit most of the central European countries. These windstorm hurricane-force winds caused serious damage to structures, to a large n

The paper is intended as an analysis of microseismic vibrations before and during the windstorm named “Kyrill”, which occurred in mid-January 2007. Microseisms were observed at the Ostrava-Krásné Pole (OKC) seismic station, where broadband seis

Seismic waves generated by earthquakes, quarry blasts, ocean waves and various technological sources cause vibrations that spread through underlying strata into the broad vicinity of these sources. The aim of our experiments was to identify and chara

Jednou z oblastí, kde byl prokázán výskyt indukovaných seismických jevù v prùbìhu posledního desetiletí, je jihozápadní èást ostravsko-karvinského revíru, kde se nalézají doly Staøíè a Paskov. Od r. 1990 byly nìkteré indukovan

Annual drift is typical for microseisms. We propose a model based on thermoelastic wave generation that explains the highest microseisms during winter using higher stress level at the same time. If we remove the average influence of the background st

The basic scientific question of this study was: do other mechanisms exist for excitation of secondary microseisms aside from the widely accepted mechanism by non-linear interactions of respective ocean waves. Here we use continuous broadband data fr
