Figure 5
Spatial distribution of CO concentration anomalies before and after the Yutian earthquake on February 12, 2014. 1—Peru fracture; 2—Ashe Cooley-Xiaoerkule fracture; 3—Kangxiwa fracture; 4—Kuyake fracture; 5—Guozhacuo fracture; 6—Longmucuo-Bangdacuo fracture; 7—Margai Caka fracture; 8—Gonggacuo fracture; and 9—Arerjin fracture. Red five-pointed star indicates the epicenter location.
