    Notes: The effect of m-phenylenedimaleimide on the rate of cross linking of synthetic rubbers, polyvinyl acetate, polyvinyl chloride, polyethylene, and other polymers, under the action of ionizing radiation is described. The dose reduction factor for equivalent degrees of crosslinking obtained with and without the maleimide varies from 10 to 25 for the synthetic rubber. Further evidence is given to show that maleimides sensitize the vulcanization of unsaturated polymers, principally by copolymerization, and certain saturated polymers containing labile atoms, by a transfer mechanism.

    Aftershocks driven by a high-pressure CO2 source at depth (2005)
    Details
    Publication Date: 2022-05-04
    Description: In northern Italy in 1997, two earthquakes of magnitudes 5.7 and 6 (separated by nine hours) marked the beginning of a sequence that lasted more than 30 days, with thousands of aftershocks including four additional events with magnitudes between 5 and 6. This normal-faulting sequence is not well explained with models of elastic stress transfer1,2, particularly the persistence of hanging-wall seismicity3 that included two events with magnitudes greater than 5. Here we show that this sequence may have been driven by a fluid pressure pulse generated from the coseismic release of a known deep source4 of trapped high-pressure carbon dioxide (CO2). We find a strong correlation between the high-pressure front and the aftershock hypocentres over a twoweek period, using precise hypocentre locations5 and a simple model of nonlinear diffusion. The triggering amplitude (10– 20MPa) of the pressure pulse overwhelms the typical (0.1– 0.2MPa) range from stress changes in the usual stress triggering models1,6. We propose that aftershocks of large earthquakes in such geologic environments may be driven by the coseismic release of trapped, high-pressure fluids propagating through damaged zones created by the mainshock. This may provide a link between earthquakes, aftershocks, crust/mantle degassing and earthquake-triggered large-scale fluid flow.
