In the Dominican Republic, the authorities say the concrete wall which collapsed last Saturday, killing nine people, was poorly designed.
The nine people, including a senior local Policeman and a prominent prosecutor from Puerto Rico, were crushed as they sat in their cars along a busy roadway in Santo Domingo, when the wall collapsed amid torrential rain.
Experts say successive governments have been warned repeatedly over the last 20 years that the wall was structurally weak and was a disaster waiting to happen.
Much of the Dominican Republic was pounded by heavy rains on the weekend caused by a tropical disturbance in the Western Caribbean.
The authorities say at least 24 people were killed by a combination of flood waters and landslides.
