Vertical-incidence reflection profiling has identified several characteristic features of the
continental lithosphere including a generally transparent upper crust, a reflective lower crust …

Analytical expressions for the static displacement field produced by a centre of dilation and
by a pressure source in a viscoelastic half-space are derived. The associated stress fields …

Long Valley Caldera is an active volcanic region in east central California. Surface
deformation on the resurgent dome within the caldera was an order of magnitude higher for …

At the present stage of development, use of geothermal energy saves about 77 million
barrels of oil per year worldwide that would otherwise be required for electrical power …

Based on both geophysical and geochemical data collected during the 1970–1972 and
1982–1984 volcano-seismic crises at Campi Flegrei caldera, the possible interpretative …

Campi Flegrei is a densely inhabited volcanic area within a caldera, 12–14 km in diameter,
immediately west of Naples, Italy. In 1970–1972 and in 1982–1984, Campi Flegrei …

Seismograms from an active seismic experiment carried out at Campi Flegrei caldera (near
Naples, Italy) show a large‐amplitude 5V‐polarized shear wave, following by less than 1.5‐s …

P and S wave amplitude data from digital, three‐component seismograms of local
earthquakes recorded on a temporary seismic array have been used to tomographically …

A procedure is described which enables us to obtain estimates of some physical and
chemical characteristics of sub-surface magma chambers. This is applied to three …

Evidence for two major geotectonic regimes in a deep level, early Proterozoic crystalline
complex is provided by its structural, metamorphic and igneous features. The earlier one is …
