Those solar panels were really well installed. Props to the installer!

[bismarckrathod]

You know you should run when birds start flying away

[josephastier]

Good to see that there are still people with enough common sense to know when to run for their lives.

[robblequoffle]

For those who don't know, there was a small firework explosion that came about 30 seconds before the giant one. You can tell that they are running away because of the initial explosion.

Props to the camera and solar panel installers!

Beirut used 4 kiloton explosion...
Solar Panels: "So anyway, I resumed collecting energy..."

[anathema]

They judged the situation correctly. If they had stayed there and continued filming with their smartphones, they would have been seriously injured.

For a moment I thought this was clickbait but damn that was wild. I’m glad to see some people with survival instinct.

[codingvio]

It is crazy how they were moments away from certain injury

[HelloWorld]

If only people in horror movies had this much common sense

[stegosaur]

god this was so horrible im so glad you all got inside. i also noticed how all the birds were flying away before the huge explosion its like they knew it was about to happen.

Bruh why am I being recommended this NOW? It's been 3 YEARS.

[horntail-wyvern]

From this distance (600 m) and the damage (severe damage to roof) I can tell that the building experienced a blast wave with a peak overpressure of 2 to 3 psi.
This means that:
Maximum blast wind speed= 102mph (approx)
Effect on Structures= Moderate effect on houses (windows and doors blown in and severe damage to roofs) Some weaker buildings may have collapsed
Effect on people= Serious injuries caused from flying debris, eardrums ruptured, fatalities could occur

[Amfibios]

Smart girls! Most people would take out their phones and start recording. I'm glad you're alive and well!

[GourmetExpressTV]

Finally, People value their lives higher than a Video or Picture to share!

[HikariSakai]

crazy how just the pressure of air going very fast causes so much destruction, insane

[rcketplumber]

Like many other videos of the Beirut explosion, you can see that the ground shock arrives first and causes significant shaking, but the air blast moments later is more destructive.

[jmash]

Have watched many different videos of this accident and the sound of that shockwave and the incredible power of the impact, never fails to take my breath away. Just gut wrenching that it happened! Those women were so very, very lucky!

[joakoite]

0:19 you can see people in the roof of the building in the left in the explosion. i hope they are ok

[BartholomewJenkins]

Ill never forget how insane this explosion was. Rip to all those who didnt make it
