ZAGREB, 22 January, 2021 - Seismologist Krešimir Kuk set up and presented new earthquake-monitoring equipment at the cemetery in Petrinja on Friday, saying it would monitor the seismic activity of the series of tremors in the wider epicentral area that began recently.
Kuk set up seismographs and accelerographs procured for Croatia's Seismological Survey by the Science and Education Ministry for HRK 4.5 million.
The Petrinja area was struck by a 6.2 magnitude earthquake on 29 December and Kuk said the series of tremors was still very active.
"As expected, in time it will become weaker, both in terms of strength and frequency, but we expect seismic activity for several more months. The more time passes, the weaker the earthquakes," he said, underlining the importance of using reinforced concrete in construction.
Kuk said seismological equipment was very important but that good equipment was never enough because it would cover only the narrow epicentral area.
"There is a shortage of manpower and equipment, and now we must achieve a whole telecommunication infrastructure for the signal from this area to reach Zagreb, where it will be promptly processed. When these 20 seismographs are set up in this wider area, we will be able to say that we have the basis for registering every earthquake that occurs in this wider area in this series."
Having procured this equipment, for the first time in Croatia's history its Seismological Survey has the possibility to rapidly respond in case of stronger earthquakes and a mobile seismological equipment set which will be used across the country as needed.
