文摘
- •
We present porosity-permeability data for rocks from Merapi, Indonesia
- •
Distinct changes in the porosity-permeability trend define changes in the dominant microstructure controlling permeability
- •
Cristobalite formation may not reduce permeability due to the associated diktytaxitic texture
- •
Low-permeability dome material is present in all historic Merapi domes
- •
A low-permeability dome did not contribute to the explosivity of the 2010 Merapi eruption
