Natural causes of the earthquake in Ecuador

1. Southwest China is located in the Mediterranean-Himalayan seismic belt, with unstable geological structure and widely distributed fault zones, which is prone to earthquakes.

2. Southwest China belongs to the eastern monsoon region, with humid climate and abundant precipitation; The rugged terrain greatly increases gravity. In case of heavy rain or continuous rainfall, the mountain rocks are loose, which is prone to landslides and mudslides.

3. Deforestation, deforestation and land reclamation have drastically reduced the vegetation coverage in mountainous areas and greatly increased the probability of landslides and mudslides.
