"Evidence for universal rupture behavior during coal and gas outbursts" by Yang Lei, Yuanping Cheng et al.

Every catastrophic coal and gas outburst begins as a tiny coal failure at almost a point, followed by violent ejection of enormous amounts of gas and pulverized coal. Whether the initial rupture of a large outburst produces observable signatures different from those of smaller events is a fundamental question associated with the potential for outburst prediction. Although outburst processes have been investigated both experimentally and theoretically, the underlying mechanism responsible for outburst rupture behavior is still poorly understood. Here, we performed a series of physical simulations and recorded the infrasound during each outburst. We found that a sharply high-amplitude (∼300 Pa) pressure wavelet followed by long (∼1 s) low-pressure acoustic waves is a common feature of outburst-generated infrasounds. These pulse-like waveform signatures have been observed during explosive volcanic eruptions, suggesting that outburst dynamics can be characterized as gas-driven eruption ....
