然后不断重复，使每一次都更接近实际地震中心，并且使假设时间与观测时间更符合合。

Then repeat this procedure, each time getting closer to the actual earthquake location and fitting the observed times a little better.

You can make a tracing of the scale and move the earthquake on the map until the tentative travel times match the travel times from the scale. Where do you think the earthquake was?
