Abstract

Seizmičnost Hrvatske posljednjih je godina slaba do srednja, a najaktivniji su obalni i
sjeverozapadni dijelovi gdje su naseljenost i seizmički hazard najveći. Važan alat pri
detektiranju potencijalne šteta i ugroženosti su karte potresne opasnosti (ShakeMap) i njihovi
scenariji koji prikazuju očekivanu prostornu raspodjelu zabilježenih i/ili procijenjenih iznosa
intenziteta potresa na određenom području. Osim toga, karte daju uvid u raspodjelu vršne
brzine i ubrzanja te spektra odziva na... More potresnom području. U ovom radu, generirane su karte
potresne opasnosti za seizmičke zone Hrvatske koristeći digitalne zapise dostupne od
2002. godine te scenariji potresne opasnosti za povijesne potrese čiji digitalni zapisi ne
postoje, a generiraju se na osnovi podataka o magnitudi i koordinate hipocentra. Kako
promjenjivost u gornjem geološkom sloju ima važnu ulogu u prostornoj razdiobi intenziteta
potresa koristili smo litološku kartu Hrvatske i izračunate brzine S valova u gornjih 30
metara (Vs30) kako bismo imali bolji uvid u očekivane amplifikacijske efekte. Less

Abstract (english)

Seismic activity of Croatia in last few years was weak to moderate and most seismically
active were the coastal and nortwestern parts where population density is high and
infrastructure is vulnerable. Important tools in damage and hazard assessment are shakemaps
and scenario shakemaps, which show the expected ground-shaking intensity distribution
patterns and estimated peak ground motions (velocity, acceleration and response spectra). In
this study we used digital ground motion... More recordings, available since 2002, to generate
shakemaps for each seismic zone in Croatia and shakemap scenario of significant historical
events of Croatia. Variability in near surface geology plays an important role in earthquake
ground shaking; we use litology map of Croatia and calculated mean share wave velocities
down to 30 meters depth in order to have a better insight into the site amplification effects. Less
