(b) Measured from the fault plane of Ji and Zeng (2007).
(c) Inferred from local zonation maps (Aguilar and Alva 2007) and from Tavera et al. (2007), and can only be considered an estimation. Firm ground stations are those located in a deposit locally known as "Lima Conglomerate", a dense, slightly cemented gravel deposit.
(d) Station E1 is located on an embankment crest.
