How often do volcanoes erupt/blow without warning in our current day and age? I know that our monitoring and sensors/technology have gotten better with time, but sometimes nature just happens.

So my question is, how likely in the estimation of volcanologist/geologists is it for a devastating eruption to happen without any evacuation warning for the nearby towns?

I tried to Google fu the statistics bit mostly just got lists of eruptions in the past 50-100 years, not how much advanced knowledge of the activity we had.
