NASA gives a staggering view of the Beirut blast damage with satellite data



On August 4, the city of Beirut experienced a huge, extremely catastrophic explosion that took the lives of many people and caused extensive damage. Many videos of the event show explosions from different angles, as well as the impact it caused, but it’s difficult to fully understand the extent of the damage. Here to help with that is NASA, which has published maps showing the extent of the damage caused by the Beirut explosion using satellite data.

The relatively small Beirut explosion, which involved the fire in a hangar containing fireworks, can be seen in the videos of the original incident. However, a second – and rather large – explosion ensued, causing a mushroom cloud and shock waves quickly spread outside, killing lives, injuring and destroying the attack. submit.

Various monitoring systems have recorded the explosion equivalent to a magnitude 3.3 to 4.5 earthquake. According to experts, this is one of the biggest explosions coming from non-nuclear sources. To assess the extent of damage, NASA̵

7;s Advanced Rapid Imaging and Analysis (ARIA) team teamed up with Singapore’s Earth Observatory to create a map of the damage.

The rendering is generated using satellite data for the purpose of observing changes on the ground that occur before and after some major event – usually an earthquake, but in this case the explosion. As you can guess, the darker the red in the map above, the more severe the damage in those regions is.

NASA says the map has a resolution of 33 yards per color pixel. The outer yellow bands on the map show areas that are ‘less damaged’, the space agency explained.

There is an obvious benefit to creating such maps – in addition to helping to visualize the extent of destruction, the maps also allow government agencies and supporting organizations not to enter areas most in need, in the end help them prioritize resources to achieve the most effective results.
