Yuri was completely stunned, and the three other Russians with him immediately took off their hats.
The one with the green hat clutched it in his hand and turned to look north, muttering something under his breath that no one could understand.
Yuri whispered, "What you've monitored? How? Are satellites operative? X-rays? Gamma rays? Or visible light, electromagnetic pulse? What is it? What exactly is it?"
Yuri seemed desperate and anxious. Yaral shook his head and said softly, "Seismic waves. We detected it through seismic waves. It could only be a thermonuclear reaction, an on-ground thermonuclear reaction, not at a single location, almost simultaneously. We suspect that a number of nuclear bombs were detonated on the ground at the same time, at least megaton-level yield. Under such circumstances, it could only mean that your people deliberately triggered a massive number of thermonuclear reactions."
