Table 2.
Characteristics of landslide exposure comparing those who were displaced and those who were not displaced [mean (SD)] in Banjarnegara, Indonesia, between 2014 and 2018 ().
Exposure characteristic | Description | Displaced () | Not displaced () | -Value |
---|---|---|---|---|
Number of landslides | Total number during study period (2014–2018) | 1.09 (0.34) | 1.18 (0.48) | 0.023 |
Average number per year since first landslide during study period (2014–2018) (landslides per year since first during study period)a | 0.55 (0.38) | 0.78 (0.36) | ||
Time since last landslide exposure | Years since last exposure within the study period (2014–2018) | 3.01 (1.78) | 1.92 (1.45) | |
Severity of exposure (0–10 scale) | Personal landslide exposure (cumulative for all landslides during the study period)b | 4.80 (2.76) | 2.21 (2.08) | |
Average personal landslide exposure (average across all landslides during the study period) | 4.50 (2.42) | 1.78 (1.33) |
Note: -Values are for -tests. SD, standard deviation.
This value reflects the number of landslides a person experienced each year of the study period (2014–2018) after their first landslide exposure. For example, if a person first experienced a landslide in 2015, it would be the average number of landslides between 2015 and 2018.
Personal landslide exposure is a composite score used to assess the severity of exposure. Values range from 0–10, where higher scores indicate more severe exposures.
