Proposte per lo sviluppo della rete meteorologica nelle Alpi Occidentali
Geofisica pura e applicata - Tập 17 - Trang 234-237 - 1950
The writer wants to emphasize the necessity of reorganizing rationally the system of the meteorologic observatories in the Western Alps, especially of the ones on the highest mountains which are the most important for the study of the variations of glaciers. For that reorganization it is necessary to remember the variety of the climatic regions into which the Western Alps may be divided. The write......
Microseismic Event Detection Kalman Filter: Derivation of the Noise Covariance Matrix and Automated First Break Determination for Accurate Source Location Estimation

Some comparisons between mining-induced and laboratory earthquakes
Geofisica pura e applicata - Tập 142 - Trang 467-489 - 1994
Although laboratory stick-slip friction experiments have long been regarded as analogs to natural crustal earthquakes, the potential use of laboratory results for understanding the earthquake source mechanism has not been fully exploited because of essential difficulties in relating seismographic data to measurements made in the controlled laboratory environment. Mining-induced earthquakes, howeve......
Seismic Ground Motion in Napoli for the 1980 Irpinia Earthquake
Geofisica pura e applicata - Tập 161 - Trang 1239-1264 - 2004
— The seismic ground motion in the urban area of Napoli has been computed for the 1980 earthquake (M
s
= 6.9) with a hybrid technique based on the mode summation and the finite difference methods. The detailed geological setting of each quarter has been reconstructed from several stratigraphies and six geological zones have been recogniz......
Forecasting Wave Amplitudes after the Arrival of a Tsunami
Geofisica pura e applicata - Tập 171 - Trang 3501-3513 - 2013
The destructive Pacific Ocean tsunami generated off the east coast of Honshu, Japan, on 11 March 2011 prompted the West Coast and Alaska Tsunami Warning Center (WCATWC) to issue a tsunami warning and advisory for the coastal regions of Alaska, British Columbia, Washington, Oregon, and California. Estimating the length of time the warning or advisory would remain in effect proved difficult. To addr......
La réflectivité d'un sédiment marin poreux
Geofisica pura e applicata - Tập 105 - Trang 713-728 - 1973
Les formules établies pour les liquides ou les solides sont pratiquement applicables aux sédiments poreux saturés non-consolidés, contrairement aux grés. L'étude présentée permet de comprendre la nature de l'onde longitudinaleP2 et du couplage dynamique. Elle illustre l'extension du principe de Huyghens aux mileux poreux.
The concentration of molecular H2 and CH4 in the stratosphere
Geofisica pura e applicata - Tập 106 - Trang 1352-1360 - 1973
Stratospheric profiles of CH4 and H2 over eastern Texas have been derived up to 31 km altitude from air samples collected aboard a balloon and analyzed by gas chromatography. For H2, contamination during flight and measurement presented a problem which has been resolved only recently. The earlier profiles require corrections which are rather large for the highest altitudes. The three profiles indi......
