Figure 2. Station 007. Top panels: Q–1 (i.e., t*
normalized to travel time) versus backazimuth at 1 Hz (left) and 10 Hz (right).
Distance r from 10 to 38 km, black filled circles; 38 < r
< 60 km, gray squares; 60 < r < 80 km, empty triangles. Middle
panel: Q–1 shown as a circle located in correspondence
of the earthquake epicenter and filled in accordance with a gray palette table.
Bottom panel: projection of the Q–1 values over a
west–east vertical plane located at the latitude marked by the black cross
