According to the USGS/NEIC QUICK EPICENTER DETERMINATIONS (Golden, CO - NO. 0-186 JUL 4, 2000) the SOUTH INDIAN OCEAN earthquake is the only magnitude 7.5+ earthquake that happened worldwide in July-December 1999. It has the following parameters:

Date and Time: 2000/06/18 14:44:12
Lattude:  13.962S
Lontitude: 97.473E
Depth: 10
Magnitude: 7.8

It happened outside test area in the region of very low seismic static about a thousand km from the 04 June, Southern Sumatera earthquake.

The other two recent large earthquakes 28 March 2000 Volcano Islands, Japan Region and 04 May 2000 Sulawesi, Indonesia (see, e.g. http://wwwneic.cr.usgs.gov/neis/bulletin/mag7.html ) - are below, although close to the level defined in our Test for M7.5+ (Healy et al., 1992). Both of them happened in the Test area, but we did not aim to predict them in our experiment.
