this mine-blast wave-path research, coupled with input from the seismographic record data provided by the chain of AGSO (Australian Geological Survey Organisation) receivers. AGSO data has always shown that the 3.6- 3.9 Richter-scale quake epicentre was south of Banjawarn—but with wildly varying results from three different calculations, due to a lack of knowledge of the regional seis- mic wave propagation. Earlier Leonora- Laverton mine blasts demonstrated errors of +100 kilometres in standard AGSO algo- rithms and calculations. IRIS proudly sent me a map detailing the small rectangular area that, with 95 per cent confidence, contained the Banjawarn 28 May ‘93 quake epicentre. It exactly coincided with the plan outline of the Laverton-Jindalee Rx (receiver) site. IRIS was presumably operating on a "need to know" basis within US Government circles and was unaware of the existence of this Laverton OTHR Rx site. In fact, I supplied IRIS with most of its detailed topographic maps of this area, and I had not included information about the Laverton-Jindalee Rx site as it seemed irrele- vant at the time. This OTHR system consists of a Tx site located east of Laverton at White Cliffs, and an Rx site west of Laverton, close to the southern boundary of Banjawarn stati About five per cent of eyewitne: "Banjawarn Bang" suggested that tl area, where the fireball exploded into a huge red flare, was "ground zero". Most other eyewitnesses placed "ground zero" much further north, so I discounted these few isolated reports, but I searched this location in mid-1995 from the air and on the ground—just in case. The reason for this discrepancy between 95 per cent of eyewitness evidence of the explo- sion site and the quake epicentre calculation remains unexplained at this time. (The five per cent of eyewitnesses who saw an explo- sive flare at the Rx site were present that night with the many other witnesses who observed the explosion well north of that location.) At the time of the 28 May '93 "Banjawarn Bang", the location was virgin bush and just a planned rectangle noted on the local Mines Department maps—to warn prospectors that no mines could be allowed in this area due to future OTHR developments. In mid-1995 whilst flying an aerial search et. al., suggesting that although this Banjawarn incident in many ways resembles a clandestine test scenario, it was not caused y an explosion (nuclear or otherwise) or a normal quake, but was probably due to a three-metre iron-nickel meteorite impact. Van der Vink has been interviewed by (Australian) ABC radio and continues to ropagate the meteorite impact theory in spite of the lack of any impact crater discovery, the eculiar evidence from eyewitnesses nature of the fireball flight and its events (e.g., the large orange-red hemisphere structure), and the evidence of multiple fire- all flights along the same track at Banjawarn—each occurring on different dates/times and demonstrating very odd, sen- tient, meteorite behaviour. Continuing its research, IRIS established the best possible fix on the 28 May 1993 earthquake epicentre. This brilliant work was achieved by studying the seismic energy paths from recent mine blasts at the newly developed Bronzewing gold-mine (located some 50 kilometres west of Banjawarn). IRIS recomputed the Banjawarn quake epi- centre using new algorithms deduced from NEXUS - 91 — BRIGHT SKIES: Top-Secret Weapons Testing? — Continued from page 50 AUGUST - SEPTEMBER 1997
