First order phase transitions at supranuclear densities may lead to neutron star corequakes. Universal formulae for the changes of the stellar parameters implied by the appearance of a small condensed core of the new phase are given. The only relevant property of the new phase is the relative density jump at the transition pressure. The parameters determining the linear response of the stellar radius, surface redshift, moment of inertia, and energy release are calculated for severel realistic equations of state of the ordinary phase of cold dense matter, in a broad interval of central densities of neutron stars. The results are given in the form of plots suitable for practical use in actual calculations. The linear response parameters represent an additional characteristics of realistic neutron star models.
