CATALOG OF EARTHQUAKES FOR PERU
HYPOCENTER OF INTENSITY DATA
NATIONAL REPORT
Daniel Huaco
The seismic catalog of Per,, (85.1 version) has two sections: Catalog of
11ypocn ter and Catalog of Intensitie s, both parts making an integrated catalog
wicreyv, uv'dcr ,auniform format, available historiral and instrumental information
has b ,ii h,,mognized and appropriately classi fied.
hI'll,e Catal a; It-o both lHypocenturs and Intensities is a result of a combination

of the Dir1,arp r '.at: :;n; of America States (OAS) and the administrative coordina­
