For each PGA instrumentally recorded, a single MMI value was assigned based on the geographic proximity to the PGA observation. A total of 330 values of both the largest PGA of the two horizontal components (PGA max ) and the average of the two horizontal components (PGA ave ) were associated to MMI values. The correlations obtained are: MMI=2.30log(PGA max )+0.92 and MMI=2.33log(PGA ave )+0.76 for MMI II-V and MMI=3.82log(PGA max )–1.78 and MMI=4.60log(PGA ave )–3.38 for MMI V-VII. Predicted PGA intervals for each intensity unit were proposed based on these equations. There is a fairly remarkable agreement between the PGA max vs. MMI found in this study and the correlation calculated by Wald et al. (1999a) for California. 2008 artículo científico 0256-7024 https://www.redalyc.org/articulo.oa?id=45437345006 en 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.38 |
