On October 31, New York saw the deadliest terrorist attack since September 11, 2001, when 29-year-old Sayfullo Saipov drove a truck down a bike lane, killing eight people and injuring more than a dozen.
With fears of attacks around the world at a high, Carnegie Mellon researchers teamed up with Robert Muggah, a global security expert and director of the think tank Igarapé Institute, to visualize terror risks from a bird’s-eye view.
Together, they created Earth TimeLapse, an interactive platform that relies on data from the Global Terrorism Database to create maps of how many terrorism-related deaths occur annually worldwide. The larger the red circle, the more deaths in a given attack.
The project mapped attacks between 1997 and 2016 — here’s what 20 years of that data looks like.
1997: Suicide bombings in Israel killed more than a dozen people and injured more than 150. Bombings also took place in Sri Lanka and Egypt. A shooting took place in India, killing 23 and injuring 31.
1998: The greatest losses of life due to terrorist activity came in Kenya and Tanzania. Members of Al-Qaeda bombed two US embassies, killing more than 200 and injuring over 4,000.
1999: The worst activity occurred in the southwestern Dagestan region in Russia, just west of Kazakhstan. A series of bombings struck apartment buildings, killing nearly 300 and injuring more than 1,000. Debates still swirl about whether Chechen separatists carried out the attacks, or whether the Russian government staged them to foster support for electing Vladimir Putin.
