Acting President Delcy Rodríguez has also introduced measures which include a request from private companies to provide machinery to remove debris and the creation of a $200 million fund for assistance. On a website called "Desaparecidos Terremoto Venezuela," or Missing persons from the Venezuela earthquake, over 36,000 people have been reported as missing, over 2,000 have been reported as being located. These reports are all from people reporting on their own on the website, and are not confirmed. .Venezuela lies along the boundary between the Caribbean and South American tectonic plates, which are moving past one another.The USGS claims the sudden release of friction between the two plates is what likely triggered the earthquake.
