Two new earthquakes hit the city, one on 19 November 1822, and another on 20 February 1835. These two events, however, did not prevent the city's rapid, continued growth. In 1820 the city reported 46,000 inhabitants, while in 1854, the population reached 69,018. In 1865, the census reported 115,337 inhabitants. This significant increase was the result of suburban growth to the south and west of the capital, and in part to La Chimba, a vibrant district growing from the division of old properties that existed in the area. This new peripheral development led to the end of the traditional checkerboard structure that previously governed the city center.
