Observations of Deformation
| Volcano number: | 311070 |
|---|---|
| Region: | Alaska |
| Country: | United States |
| Geodetic measurements? | Yes |
| Deformation observation? | Yes |
| Measurement method(s): | InSAR |
| Duration of observation: | 1995 - 2009 |
| Inferred cause(s) of deformation: | Surface deposits |
| Characteristics of deformation: | Between 1995 and 2009, the south flank of Garloi subsided at ~1 – 1.5 cm/yr. The subsiding area corresponds to a region of lava and pyroclastic deposits from the twentieth century, and subsidence is attributed to thermoelastic compaction of lavas and mechanical compaction of tephra. |
