Welcome to Forum #504
Searching for oil in Abu Dhabi 1971. Seismographing for oil deposits. Basically, set a series of charges below ground, detonate and record the outcome, tells you what's under the ground. The explosives have to be set to correct depth and detonated with specific timing. What you're seeing is a line of explosions set to go off simultaneously. They must have been close to what they were looking for or eliminating an area from further testing. (Thanks Daryl)
