Yes they are dutch, and they EXPECT the eruption.
Prior to the eruption they talk about they are waiting for it to erupt.
So maybe it's like a geiser at some places, they erupt like clockwork.
Mt Stromboli has been in almost one continuous eruption for the past 20,000 years. This pattern of eruption has been maintained, in which explosions occur at the summit craters with mild to moderate eruptions of incandescent volcanic bombs at intervals ranging from minutes to hours. This characteristic Strombolian eruption, as it is known, is also observed at other volcanoes worldwide. Eruptions from the summit craters typically result in a few second-lasting mild energetic bursts emitting ash, incandescent lava fragments and lithic blocks up to a few hundred metres in height. Stromboli's activity is almost exclusively explosive, but lava flows do occur at times: an effusive eruption in 2002 was its first in 17 years.
Strombolian eruptions are relatively low-level volcanic eruptions, named after the Italian volcano Stromboli, where such eruptions consist of ejection of incandescent cinder, lapilli and lava bombs to altitudes of tens to hundreds of meters. They are small to medium in volume, with sporadic violence.
They are defined as "...Mildly explosive at discrete but fairly regular intervals of seconds to minutes..."
