From what I can guess, the video was taken on N. Reagan Street at the lower left of the FOV in this Google Maps view. It seems that the fire and explosion was in that brownish round structure with the "West Fertilizer" label. The apartment complex is north of the POV to the east of N. Reagan St., just opposite the explosion site.

A blast wave in fluid dynamics is the pressure and flow resulting from the deposition of a large amount of energy in a small very localised volume. The flow field can be approximated as a lead shock wave, followed by a 'self-similar' subsonic flow field. In simpler terms, a blast wave is an area of pressure expanding SUPERSONICALLY outward from an explosive core. It has a leading shock front of compressed gases. The blast wave is followed by a blast wind of negative pressure, which sucks items back in towards the center. The blast wave is harmful especially when one is very close to the center or at a location of constructive interference. High explosives, which detonate, generate blast waves.

"Unlike ordinary sound waves, the speed of a shock (blast) wave varies with its amplitude. The speed of a shock (blast) wave is always greater than the speed of sound in the fluid and decreases as the amplitude of the wave decreases. When the shock wave speed equals the normal speed, the shock wave dies and is reduced to an ordinary sound wave.

This reminds me of the Texas City chemical explosions of 1947.

Of which, my father was the only survivor remaining from the Texas City Heights Fire Dept. He was out of town the morning of the blast in Alvin, Tx. The blast wiped out the dock where the firefighters stood and no one lived.

I hope she gets her hearing back.

- - - - - -
So do I. If it is just tinnitus and swelling she probably will, but if it ruptured her eardrums, there is little they can do other than a tissue graft and those have low sucess rate.

FWIW, ruptured eardrums are how I lost my hearing several years ago.

In Pascagoula, MS there is a large fertilizer plant within eyesight of one of the largest Chevron refineries in the country. If one goes, they both go. Scary as hell. It’s all surrounded by residential areas.

This comment not directed at you, bigtigermike, but to all those that are critical of the poor guy that filmed this video, WHICH I MAY ADD, EVERYONE IS STILL WATCHING IT IN SPITE OF THE CIRCUMSTANCES.....
The guy is out driving around with his family. He sees a fire in the distance and videos it with his camera. Let’s give this fella the benefit of the doubt. You don’t see something like that everyday. You can hear him saying “it should collapse soon” so he doesn’t have a clue it is going to explode. I don’t think his intention was to put his child at risk, he was 1/4 miles away. Who would know that was too close? While he is filming, the explosion occurs, after which you hear the little child crying and being scared. It was a major blast, I am sure the concussion from the force was jarring to say the least. It is an important piece of evidence and all the major news sources are running it. SO WHAT?!? Get over your judgemental selves. In this day and age everyone is a reporter, like it or not. And so what if he posted it, if he didn’t, you wouldn’t have anything to complain about.
There, I feel better.

Check your facts this is NOT the blast. It is from another explosion. Has been retracted all over the internet.

To: All

Here are some facts about the weather during and after the blast. The Waco region was in a warm, humid but otherwise dry air mass at the time of the blast, with south to southeast winds at about 25-35 mph. There may have been a higher than average buildup of static electricity near the surface as the air mass was stable and ahead of an active front. At that time, the front was at least 150 miles to the northwest of the site of the blast. Now (0230 CDT) the front is about a hundred miles away and will arrive about 0700h, causing the wind to change rapidly to NNW 25-40 mph. There could be a brief thunderstorm or rain shower with the front.

Just wanted to add this to the discussion because in the usual fog of internet info-overload there are bound to be false conclusions about lightning as a cause. While I think static electricity is a possible factor, there was no active weather anywhere near the scene at the time of the explosion.

And a well defined line of heavy rain should be hitting the town of West in about 30 minutes. Light rain beforehand possible. Strong winds out of ENE. Some lightning with heavy rain. Some hail. They were predicting possible tornado activity two days ago in this storm line.

Yeah. When I was in the USN, they used to drop bombs on targets in the water, and you would feel and hear the explosion through the hull long before you heard it in the air...

So, the following from Wikipedia is wrong? (I’m not saying Wikipedia is infallible. Far from it. Just wondering what your take on this is.)

“When a shockwave is created by high explosives such as TNT (which has a detonation velocity of 6,900 m/s), it will always travel at high, supersonic velocity from its point of origin.”

This raises the question as to how far the First Responders had the perimeter?

Obviously something failed here in the EMS response plan and/or the fire chief failed to properly implement it.

Every plant like this has a government approved plan. When I worked as the Safety Manager for a Haz. Waste facility, if there was a fire...the evac plan was a minimum of 2 miles. A fertilizer plant would be no different, really.

If you watch the fire closely, you see the flare-up just before the explosion.

Actually, I’ve seen the post now several times he is 1/4 mile away....

If you look closely, he is just outside the fenceline to the plant! This raises a huge red flag as to way authorities had not secured the area.

Texas City Explosion - April 16, 1947

The Texas City disaster was the deadliest industrial accident in U.S. history. The incident took place on April 16, 1947, and began with a mid-morning fire on board the French-registered vessel SS Grandcamp which was docked in the Port of Texas City. The fire detonated approximately 2,300 tons of ammonium nitrate[1] and the resulting chain reaction of fires and explosions killed at least 581 people, including all but one member of the Texas City fire department.[2] These events also triggered the first ever class action lawsuit against the United States government, under the then-recently enacted Federal Tort Claims Act (FTCA), on behalf of 8,485 victims.

Son (I think).

He was far enough away that the average person would feel they were safe.

As an chemical engineer, I would have backed up a few more miles.

Its a dangerous world, always will be, there will never ever possibly be any perfect society, gun free, murder free, lions nd sheep kissing each other, no care, no pain, no worry.

Shit happens, one day you are here, the next you are gone.

I for one won’t spend hours and hours concerned about the welfare of hours, its a big enough job all on my lonesome just trying to get through a days work without getting hurt, driving home dead tired at the wheel, hoping my pains and aches are temporary and not the message of something worse.

My biggest rebellion is telling those “superior trained compassionate liberals” to eff themselves and stay out of my life.

This was 6 days ago!!

“A disposal team from Fort Hood removed an apparent home-made bomb early Friday after police discovered it inside a pickup truck during a routine traffic stop at a Waco intersection.”

It included a hand grenade and was reported as being “live”.

I suppose you’re right about that. All I know is I would not live any where near a fertilizer or chemical plant. I would tell my realtor to look in a different location. We used to live near a rendering plant and I can tell you that sometimes the smell was so bad that it wilted the flowers! I’m serious.

“On June 11, 1892, West was officially organized into a town. It had become the center of commerce for the area. There were cotton gins, grocery stores, churches, schools, and doctors’ offices.”

“The turn of the century brought electricity, running water, and natural gas. The population of West and surrounding area grew.”

http://en.wikipedia.org/wiki/West,_Texas#History

No mention of a fertilizer plant being the reason West came into existence. The main reason for the towns existence and growth was the railroad. No mention whatsoever of a fertilizer plant being there first and people built the town around it.
