Figure 11. Although the Kamchatka earthquake took up to a minute longer to rupture than the Maule event, both were substantially complete by about 200 seconds after they nucleated, and so their rupture speeds are unlikely to explain their tsunami differences. Both source time functions were constructed by the USGS from similar data, using similar methods. Credit: USGS source time functions overlaid by Temblor, CC BY-NC-ND 4.0
