Since Manila is prone to earthquakes, the Spanish colonial architects invented the style called Earthquake Baroque which the churches and government buildings during the Spanish colonial period adopted. As a result, succeeding earthquakes of the 18th and 19th centuries barely affected Manila, although it did periodically level the surrounding area. Modern buildings in and around Manila are designed or have been retrofitted to withstand an 8.2 magnitude quake in accordance to the country's building code.
