124 Andes, together with the scarcitv of seismic stations especially for the control East-West, have been a svstematical origin of errors). Some hypocenters not appearing in international catalogs were added after their magn itude was realized to he 4.5 or more. About 800 1ocation: W nailer earthquakes are not included in the catalog, but afforded an indis .. , iirmation of determination quality. Bolivian se ismol Isic.l .staLionS contributing data: La Paz (LPZ) 1913 1963; La Paz (l.PB) sincp 190K; Zogo (tripartite) since 1972; Pe~as (PNS) 1965-1975. Short-lived stati ns: Cocha bamba, Desaguadero, Samaipata, Tarija, Sicasicai, Riberalta, ('roice. The intensity catal,. (on th, ia;is of SISAN catalog) has been largely improved not on]y ieCuisc of its critical revision and continuation through the end of 1981, bit especiaIlly bv tie search of more data in old newspapers and archiv es and by inte rvi owing people in several epicentral zones ( this research was 'ombined with fiold trips for tectonic investigation; see comments to the flet.toct00o i ' map).

METHODS USED IN TiE DEI)IVELOPMENT OF TIlE CATALOGS 1. lpocnter paraMteLrs taken from seismological agencies mentioned above were accepted unchanged, except when readings a- La Paz clearly were not compat ible wit Ih that data. When hypocent:er parameters were calculated in the Observatorio San Calixto, Mohorovicic method was used, by restricting the area in which earthquake could originate and then accepting within this area the location giving minimum square residuals for the stations considered. Depth was restricted considering auxiliary criteria such as area of perception, number of aftershocks, prevalent d(1Lth for greater earthquakes in the zone. Magnitude mb was calculated after amp] i tide of body waves or obtained through comparison with surfac M or local M, magnitrudes; when M S was available was also Si sted. L log A/I" + 1.8 log A' + 3.5 and related to intensity, for historical earthquakes:
125 M = 1.08 + 0.62 fmx 2. Intensitv data were translated into the Mercalli Modified scale also when the only information retained was the degree in the scale Rossi- Forel. PLANS FOR FUTURE U;PDIATING OF 'iHE CATALOGS Ihe Observntorio Snn Calixto maintains the plan of collecting data any time an earthquak e will occur in Bolivia, both location pnrameters and macro seismic data. Consul tation of a rchives and old publications looking for complementary data deal ingt with hi ;toric earthquakes will also continue. AI)DITIONAL. REF ER'ENCES: See page 23.
