    Description: In September 2014, a five week long slow slip event (SSE) occurred near Gisborne at the northern Hikurangi subduction zone, New Zealand, and was recorded by offshore instruments deployed by the Hikurangi Ocean Bottom Investigation of Tremor and Slow Slip (HOBITSS) project. Up to 25 cm of slip occurred directly below the HOBITSS array. We calculate shear wave splitting (SWS) and ratios for event-station pairs on HOBITSS ocean bottom seismometers and onshore GeoNet seismic stations to determine the relationship in time and space between slow slip and these seismic properties. Spatial averaging of SWS fast azimuths yields trench-perpendicular fast azimuths in some areas, suggesting that compressive stress from plate convergence closes microcracks and controls anisotropy in the upper-plate. Variations from the trench perpendicular directions are observed near a subducting seamount, with directions closely resembling fracture and fault patterns created by subducting seamounts previously observed in both laboratory and field experiments. Temporal variations in fast azimuths are observed at three stations, two of which are located above the seamount, suggesting measurable variations in stress orientations. During the SSE, median measurements across all offshore stations increase from 1.817 to 1.894 and SWS delay times decrease from 0.178 s to 0.139 s (both changes are significant within 95% confidence intervals). Temporal variations in and delay time are consistent with fluid pressurization below a permeability barrier and movement of fluids during the rupture of a slow-slip patch.

    Description / Table of Contents: Riassunto La dipendenza degli spettri di Raman di primo ordine dalla pressione idrostatica in cristalli di ZnSiP2 è stata misurata fino a 52k bar e il parametro di Grüneisen di ogni modo di Raman è stato ottenuto. I modi fononici osservati nel cristallo di ZnSiP2 possono essere classificati in cinque gruppi secondo il valore del parametro di Grüneisen del modo. La corrispondenza tra modi di Raman in ZnSiP2 e quelli nel suo analogo binario GaP è stata chiarita confrontando i parametri di Grüneisen nei due cristalli. Da tale corrispondenza sono stati chiariti complicati modi di vibrazione reticolare in ZnSiP2.
    Abstract: Резюме Измеряется зависимость от гидростатического давления вплоть до 52 кбар Рамановских спектров пектров первого порядка в кристаллах ZnSiP2. Для каждой Рамановской моды получен параметр Грюнайзена. Наблюденные фононные моды в кристалле ZnSiP2 могут быть классифицированы а пять групп, соответственно параметру Грюнайзена. Объясняется соответствие между Рамановскими модами в ZnSiP2 и Рамановскими модами в бинарном аналоге GaP, посредством сравнения параметров Грюнайзена в двух кристаллах. Это соответветствие проясняет сложные моды колебаний решетки в ZnSiP2.
    Notes: Summary The hydrostatic-pressure dependence of the first-order Raman spectra in the ZnSiP2 crystal has been measured up to 52 kbar and the Grüneisen parameter of each Raman mode was obtained. Phonon modes observed in the ZnSiP2 crystal can be classified into five groups according to the value of the Grüneisen mode parameter. The correspondence between Raman modes in ZnSiP2 and those in its binary analog GaP was elucidated by comparing Grüneisen parameters in the two crystals. From such a correspondence, complicated lattice vibration modes in ZnSiP2 were made clear.

    Description / Table of Contents: Riassunto Si sono fatte misurazioni degli spettri di fotoluminescenze e di eccitazione luminescenza di ZnSiP2 a 4.2 K e si sono ottenuti due risultati. Uno è l'osservazione di una nuova linea netta di emissione a 1.980 eV, dovuta all'eccitone legato associato col gap pseudodiretto. L'altro è l'osservazione di un'altra nuova serie di linee di assorbimento nello spettro di eccitazione di luminescenza di una linea di emissione a 1.984 eV, oltre a quelle riportate in precedenza. Questi risultati indicano che in ZnSiP2 si verificano transizioni radiative sia per gap indiretti che per gap pseudodiretti.
    Abstract: Резюме При 4.2 К проведены измерения спектров фотолюминесцендии и спектры возбуждения люминесценцией в ZnSiP2 и получено два результата. Один результат представляет наблюдение новой резкой линии излучения при 1.980 эВ. обусловленной связанным экситоном, ассоциированным с псевдопрямым интервалом. Второй результат предсталяет наблюдение новых линий поглошения в спектре возбуждения люминесценцией линии излучения при 1.984. эВ. Эти результаты указывают, что в ZnSiP2 радиационные переходы происходят при косвенных и псевдопрямых интервалах.
    Notes: Summary Measurements of photoluminescence and luminescence excitation spectra of ZnSiP2 have been performed at 4.2K and two results were obtained. One is the observation of a new sharp emission line at 1.980 eV, due to the bound exciton associated with the pseudodirect gap. The other is the observation of another new series of absorption lines in the luminescence excitation spectrum of an emission line, at 1.984 eV, in addition to those reported previously. These results indicate that in ZnSiP2 radiative transitions occur at both the indirect and the pseudodirect gaps.
