The dominant feature of Panama's geography is the central spine of mountains and hills that forms the continental divide. The divide does not form part of the great mountain chains of North America, and only near the Colombian border are there highlands related to the Andean system of South America. The spine that forms the divide is the highly eroded arch of an uplift from the sea bottom, in which peaks were formed by volcanic intrusions.
Newspaper Ming Pao fired deputy editor Keung Kwok-yuen following a front-page article on the Panama Papers which mentioned many prominent Hong Kong citizens. The paper blamed a "difficult business environment," but had previously fired another editor in 2014 over another leak of offshore documents. Employees have been publishing blank columns scattered through the newspaper in protest of his dismissal.
The city was founded on August 15, 1519, by Pedro Arias de Ávila, also known as Pedrarias Dávila. Within a few years of its founding, the city became a launching point for the exploration and conquest of Peru and a transit point for gold and silver headed back to Spain through the Isthmus. In 1671 Henry Morgan with a band of 1400 men attacked and looted the city, which was subsequently destroyed by fire. The ruins of the old city still remain and are a popular tourist attraction known as Panamá la Vieja (Old Panama). The city was rebuilt in 1673 in a new location approximately 5 miles (8 km) southwest of the original city. This location is now known as the Casco Viejo (Old Quarter) of the city.
