Complete EEW workflow for a close earthquake from the landside (\(\textrm{M} = 3.3\); 2024-03-23 18:35:56). (a) Strain rate data. Blue and yellow markers depict fiber segments where P or S was detected, respectively, while red markers denote unassigned and potentially erroneous picks. (b) Location score maps at different time steps. Dark colors represent highly scored areas. The green cross depicts the real-time updated location, and the star shows the catalog location. Blue shade and yellow markers depict fiber segments where P or S was detected, respectively. (c) Real-time estimated magnitude, averaged over all short segments. The shaded background depicts the standard deviation. (d) Difference between predicted and observed (accelerometers) \(\text {log}_{10}\)PGA averaged for all epicentral distances. The shaded background depicts the standard deviation.
