Earthquakes in Ambato: The 1949 Ecuadorian Disaster

Yes, Ambato is a high earthquake-risk zone. The capital of Tungurahua province, in Ecuador's central highlands, sits in the inter-Andean valley, a corridor crossed by active geological faults and surrounded by volcanoes, placing it among the Ecuadorian cities most exposed to earthquakes.

The risk has two components. On one hand, the subduction of the Nazca plate beneath the South American plate off Ecuador's coast generates large earthquakes felt far inland. On the other, and more decisive for Ambato, there are shallow crustal faults within the inter-Andean valley itself, capable of producing destructive earthquakes very close to the city. The nearby Tungurahua volcano adds earthquake activity of volcanic origin.

The most tragic episode was the earthquake of 5 August 1949, with a magnitude near 6.8 and its epicentre close to Ambato. It destroyed much of the city and numerous towns in the province, killing around 6,000 people, one of the greatest seismic disasters in Ecuador's history. The reconstruction reshaped Ambato's layout and architecture, leaving behind an awareness of living in a high seismic-hazard region.
