These techniques correspond to spectral ratios based on the recording of: ambient vibration using an accelerograph (denominated VAA), ambient vibration using a seismograph (VAS), total seismic records (ST) and a time window of 5 s staring at S waves arrives in the seismic records (SOS). Better results were achieved when VAA was applied during the day (at 8 am and 3 pm). When VAA at 3 pm was compared to VAS at day time, it was observed that in the 58% of the analyzed cases the shapes and amplitudes of the spectral ratios were different, which means that VAA is not an appropriated technique to identify f0 based on that the results from VAS are the correct ones. It is affirmed based on its similarity to ST and SOS techniques in a 75% of the studied cases. These last two techniques are better justified in both mathematical and physical fundaments. 2016 artículo científico 0256-7024 https://www.redalyc.org/articulo.oa?id=45445616008 es http://www.redalyc.org/revista.oa?id=454 Revista Geológica de América Central application/pdf Universidad de Costa Rica Revista Geológica de América Central (Costa Rica) Num.54 |
