1984 年，Witten [1] 提出，一种由上夸克、下夸克和奇夸克组成的极其致密的物质形式可能会周期性地撞击地球，并可以通过其通过时产生的地震信号来探测到。我们调查了 1990 年至 1993 年间发送给美国地质调查局的超过 100 万份与传统震中源无关的地震数据报告。如果存在的话，我们期望在这组不相关的台站报告中找到具有线形源的事件。这样的来源可能是由一块奇异夸克物质（SQM）穿过地幔而产生的。发现两组报告在到达时间、阵列指向和波形特征方面适合线形震源模型，但不适合震中震源模型或多震中震源模型。这两个事件具有预测 SQM 金块穿过地球的特性。
In 1984 Witten [1] proposed that an extremely dense form of matter composed of up, down, and strange quarks may periodically strike the Earth and be detectable by the seismic signals generated from its passage. We investigated over 1 million seismic data reports sent to the U.S. Geological Survey in the years 1990-1993 that were not associated with traditional epicentral sources. It is among this set of unassociated station reports that we would expect to find events with epilinear sources should they exist. Such a source could result from the passage of a nugget of strange quark matter (SQM) through the Earth's mantle. Two sets of reports were found that fit the epilinear source model for arrival times, array pointing, and waveform characteristics, and do not fit an epicentral source model or multiple epicentral sources model. These two events have the properties predicted for the passage of an SQM nugget through the Earth.
