In some cases the inferred volume decrease is a factor of 4 or 5 less than the volume increase of the dike. Here we explore whether this discrepancy can be explained by compressibility of the magma combined with the fact that cracks are much more compliant than equidimensional magma chambers. If pressure changes are small, the magma compressibility βm is constant, and the dike ends up in hydrostatic equilibrium with an ellipsoidal magma chamber at the same depth, the ratio rV of the volume of the crack to the volume lost by the chamber is rV = 1 + 4μβm/3 > 1, where μ is the host rock rigidity. For gas poor magmas, βm = 0.6–2 · 10−10 Pa−1 and μ = 3–25 GPa, we find 1.2 < rV < 7.7. Large changes in magma compressibility due to gas exsolution increase rV."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699995295809792","@type":"Researcher","foaf:name":[{"@value":"Eleonora Rivalta"}],"jpcoar:affiliationName":[{"@value":"Department of Physics University of Bologna Bologna Italy."}]},{"@id":"https://cir.nii.ac.jp/crid/1381699995295809793","@type":"Researcher","foaf:name":[{"@value":"Paul Segall"}],"jpcoar:affiliationName":[{"@value":"Department of Geophysics Stanford University Stanford California USA."}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00948276"},{"@type":"EISSN","@value":"19448007"}],"prism:publicationName":[{"@value":"Geophysical Research Letters"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"2008-02","prism:volume":"35","prism:number":"4","prism:startingPage":"L04306"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F2007GL032521"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2007GL032521"}],"createdAt":"2008-02-27","modifiedAt":"2023-10-31","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050852870543559424","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"The 2018 phreatic eruption at Mt.
