The paper shows how state-of-practice procedures were adapted to a region for which there are few records of ground motion but a long seismic history. 1. INTRODUCTION Quito, the capital of Ecuador, was founded in 1534 with an initial population of about 200 people and an area of about 30 hectares. By 1990, the population had increased to 1.1 million and the metropolitan area covered 290 square kilometres. The population is
