Fig. 2: Exposure to subsidence in the United States.
From: Land subsidence risk to infrastructure in US metropolises
a, The percentage of each city affected by subsidence. The warming of the colors from yellow (subsidence > 0 mm per year) to red (subsidence > 1 cm per year) is indicative of increasing subsidence. b, The total subsiding area (blue bars) and subsiding population (green bars) for each city. Supplementary Table 3 summarizes the proportion of each city affected by each subsidence level and the affected area and population.
