EHB EVENTS AND STATIONS MAP

EHB Bulletin - EHB technique (Engdahl, van der Hilst & Buland,1998)

The EHB is a groomed version of the ISC Bulletin, and contains data for 141478 events from 1960 to 2008. The Engdahl et al. (1998; EHB) algorithm has been used to significantly improve routine hypocenter determinations made by the ISS, ISC and PDE before a new ISC location algorithm (Bondár and Storchak, 2011) was introduced for data year, 2009.
