- Abstract:
- GPS stations observed from 1999 to 2018 in Tianshan region were collected and analyzed,and the linear sphere block model was used to calculate the slip rates of 1999—2007,2009—2013 and 2013—2017 period.The baseline and regional strain result in recent years in Tianshan region were analyzed,while the recent crustal deformation in Tianshan area was analyzed and earthquake hazard area were evaluated.The results showed that,the compression speed in the western section of the northern Tianshan area has a slight adjustment,while the baseline results showed that there were far field squeezing in west-middle section of the north Tianshan area,but also showed the spatial-tempral nonlinear deformation,it needs to be intentioned.Compression rates in western section of the south Tianshan are in a stable high state,with the value of 2013—2017 period up to-12.5 mm /a.The baselines and strains of the western section of south Tianshan were mainly compressive,combined with the analysis of the seismic activity,it indicates that there was a high risk in the western section of the south Tianshan.
