Yes, from what I know for a volcano we have a good geological model of what is going on, and reliable ways of measuring the relevant parameters. Still predicting an eruption is an achievement, and predicting the not eruption especially so. For earthquakes we are lacking both in models and in measurements. We don't know whether there is "a process started" in the days before a quake. This paper is looking for one.
