WEST, TEXAS - To give you an idea of the size of the blast in West, it had the impact of a small earthquake and was heard more than 40 miles away. NewsWest 9 spoke with the U.S. Geological Survey (USGS) to get an inside look at what the explosion looked like to scientists.
The USGS says the explosion was so intense, it sent major vibrations into the ground. Seismometers were able to record those vibrations at multiple USGS stations. The farthest station that was able to pick up the explosion was over 400 miles away from the town of West.
Scientists created a map of which cities felt the ground shake. A slight shake was felt in Midlothian and even far north in Plano. The magnitude of that explosion was compared to a 2.1 earthquake.
"It registered as a magnitude 2.1 earthquake but it's not a earthquake. We're using the Richter scale to show the energy to that our instruments recorded. When the explosion or when a explosion occurs that's large enough, it'll send enough energy to the ground to cause the ground to vibrate or shake. That's basically what the seismometers pick up," USGS Geophysicist, John Bellini, said.
