The amplification of seismic waves through the local geology is modeled in a seismic spectral micro-zoning study. Local seismic amplification functions and response spectrums are determined as a result. These response spectrums can be used to determine the earthquake loads on buildings instead of the response spectrums of standard SIA 261.","summaries":{"proj:epsg":[2056]},"extent":{"spatial":{"bbox":[[5.96,45.82,10.49,47.81]]},"temporal":{"interval":[["2023-06-09T00:00:00Z","2023-06-09T00:00:00Z"]]}},"providers":[{"name":"Federal Office for the Environment FOEN","roles":["producer","licensor"],"url":"https://www.bafu.admin.ch/bafu/en/home.html"}],"license":"proprietary","created":"2023-06-22T06:40:24.395359Z","updated":"2026-03-19T09:42:29.523934Z","links":[{"rel":"self","href":"https://data.geo.admin.ch/api/stac/v0.9/collections/ch.bafu.gefahren-spektral"},{"rel":"root","href":"https://data.geo.admin.ch/api/stac/v0.9/"},{"rel":"parent","href":"https://data.geo.admin.ch/api/stac/v0.9/"},{"rel":"items","href":"https://data.geo.admin.ch/api/stac/v0.9/collections/ch.bafu.gefahren-spektral/items"},{"rel":"alternate","title":"STAC Browser","type":"text/html","href":"https://data.geo.admin.ch/browser/index.html#/collections/ch.bafu.gefahren-spektral"},{"href":"https://opendata.swiss/en/terms-of-use/#terms_by","rel":"license","title":"Terms of use"},{"href":"https://www.geocat.ch/geonetwork/srv/eng/catalog.search#/metadata/a869c0d0-ff03-4cbf-93e8-c568f01bf9bc","rel":"describedby","title":"Metadata"},{"href":"https://www.bafu.admin.ch/bafu/en/home/topics/natural-hazards/topic-earthquakes.html","rel":"about","title":"Further information"}],"crs":["http://www.opengis.net/def/crs/OGC/1.3/CRS84"],"itemType":"Feature","assets":{}}
