据说，地下核爆试验与自然地震的地震波图形特征不同，在一定程度上可以区分。下图是两者的地震波图形对比。
自然地震一般都有余震，波形图会出现几个尖峰。而地下核爆试验的能量是在开始集中一次释放，之后逐渐减少。
On the evening of October 5, 2024, a seismic event in Iran's Semnan province raised eyebrows and sparked a flurry of speculation across global social media platforms, particularly on X (formerly Twitter). This event, registering at a magnitude of 4.6, led to widespread discussions and rumors about whether it was an underground nuclear test conducted by Iran or merely a natural earthquake.
The earthquake occurred in Aradan, Semnan, with its epicenter a mere 10 kilometers beneath the surface, which is relatively shallow for seismic activities of this nature. Reports are emerging that yesterday's 4.6 magnitude seismic event in Iran's Kavir Desert may have been an underground nuclear test. Lacking typical seismic waves and no aftershocks, the event is raising suspicions.

FROM 110.52.220.* - Seismic moment tensor classification using elliptical distribution functions on the hypersphere
Mark J Hoggard, Janice L Scealy, Brent G Delbridge, Published: 07 February 2024
Geophysical Journal International, Volume 237, Issue 1, April 2024, Pages 1–13
In a paper published in Geophysical Journal International, Mark Hoggard, DECRA Research Fellow of Australian National University, and colleagues have developed a way to distinguish between underground nuclear tests and natural earthquakes with around 99% accuracy.
Mark Hoggard of The Australian National University (ANU) highlights the challenge: distinguishing these seismic events using the energy patterns captured by seismometers.
The research, a collaboration between ANU and the Los Alamos government research lab in the U.S., presents a swift and reliable tool for assessing the likelihood of a seismic event being a nuclear explosion.
