About the author, via Google Translation:

I specialize in volcanic geology. Among them, we have a strong interest in the distribution of the ash is discharged from the volcano eruption. Distribution of radioactivity released from Fukushima Daiichi nuclear power plant can be understood well by applying my expertise on the ash.


No mention what unit was used, but most liquid measurements have been calculated in liters.
