Résumé :

During 1989 the Seismological Observatory recorded and analysed 9892 earthquakes in the New Zealand region. Preliminary locations and magnitudes are now available for all these events. This is about five times the number usually analysed in previous years, thanks to the new digital recording equipment which is being installed throughout the country. No earthquakes reached magnitude 6 during the year, although one of magnitude 5.9 in Fiordland was close to that figure. This caused intensity MM VI throughout Fiordland, and lower intensities elsewhere in the southern half of the South Islan

Résumé :

Determinations of surface-wave magnitude (Ms) are made on a consistent basis for 202 selected New Zealand earthquakes over the period 1901-1993, including most post-1942 events with local magnitude not less than 6.0 and centroid depth less than 45 km. These determinations have led to a reassessment of magnitudes and locations of some earlier events in the New Zealand Seismological Observatory Catalogue of local magnitudes (ML), in some cases with substantial revisions. The surface-wave magnitudes are compared with local magnitudes and moment magnitudes (Mw), where available, and the relations

Résumé :

Carter Observatory is the National Observatory of New Zealand and was opened in 1941. For more than ten years the Observatory has maintained an active education program for visiting school groups (see Andrews, 1991), and education now forms one of its four functions. The others relate to astronomical research; public astronomy; and the preservation of New Zealands astronomical heritage (see Orchiston and Dodd, 1995).Since the acquisition of a small Zeiss planetarium and associated visitor centre in 1992, the public astronomy and education programs at the Carter Observatory have witnessed a maj

Résumé :

New Zealand is a self-governed, independent nation, a member of the British Commonwealth, and a major center of Polynesian culture in the south Pacific. The country’s two main islands lie between 34° and 47° south latitude, which places New Zealand south of many well known southern observing sites such as Sydney (Australia), Cape Town (South Africa), and Cordoba (Argentina).The population of 3.5 million people inhabit a country slightly larger than the United Kingdom. The astronomical interests of this small population are nourished by no less than 25 local and regional astronomical societies.

Abstract. Instrumental seismic observations in northern Finland started in the 1950s. They were originally initiated by the Institute of Seismology of the University of Helsinki (ISUH), but the staff of Sodankylä Geophysical Observatory (SGO) and later geophysicists of the University of Oulu (UO) were involved in the development of seismological observations and research in northern Finland from the very beginning. This close cooperation between seismologists and the technical staff of ISUH, UO, and SGO continued in many significant international projects and enabled a high level of seismologi

Between 1912 and 1914, the Anglo-American popularizer of astronomy, Mary Proctor, undertook a tour of Australia and New Zealand in order to promote a solar observatory project that would ultimately be realized as the Mount Stromlo Observatory in Australia. Proctor came at the request of Walter Geoffrey Duffield, who would go on to be the first Director of the Mt Stromlo Observatory and who saw the need to raise funds and public support for the project. Proctor’s tour was high-profile and nearly saw the realization of a solar observatory as part of the Cawthron Institute at Nelson, New Zealand.

Résumé :

Carter Observatory is the gazetted National Observatory of New Zealand, and opened in 1941 December. From the start, the main function of the Observatory was to provide for the astronomical needs of the citizens of, and visitors to, the Wellington region, and today this remains one of its four recognised functions (Orchiston and Dodd, 1995). The other three are to conduct astronomical research of international significance; provide a national astronomy education service for school students, teachers, and trainee teachers; and assist in the preservation of New Zealand's astronomical heritage.

Recent progress in rotational sensor technology has made it possible to directly measure rotational ground-motion induced by seismic waves. When combined with conventional inertial seismometer recordings, the new sensors allow one to locally observe six degrees of freedom (6DOF) of ground-motion, composed of three orthogonal components of translational motion and three orthogonal components of rotational motion. The applications of such 6DOF measurements are manifold—ranging from wavefield characterization, separation, and reconstruction to the reduction of non-uniqueness in seismic inverse pr

Résumé :

AbstractThe gravity modes present in γ Doradus stars probe the deep stellar interiors and are thus of particular interest in asteroseismology. For the MUSICIAN programme at the University of Canterbury, we obtain extensive high-resolution echelle spectra of γ Dor stars from the Mt John University Observatory in New Zealand. We analyze these to obtain the pulsational frequencies and identify these with the multiple pulsational modes excited in the star. A summary of recent results from our spectroscopic mode-identification programme is given.

Earthquakes can influence flood hazards by altering the flux, volumes, and distributions of surface and/or subsurface waters and causing physical changes to natural and engineered environments (e.g., elevation, topographic relief, permeability) that affect surface and subsurface hydrologic regimes. This paper analyzes how earthquakes increased flood hazards in Christchurch, New Zealand, using empirical observations and seismological data. Between 4 September 2010 and 4 December 2017, this region hosted one moment magnitude (Mw) 7.1 earthquake, 3 earthquakes with Mw ≥ 6, and 31 earthquakes with

An automatic geomagnetic station for monitoring the Earth’s magnetic field variations was installed in December 2020 at Talos Dome, a remote site on the Antarctic Plateau, about 300 km away from the permanent geomagnetic observatory at Mario Zucchelli Station (MZS). Designed and assembled at the laboratory of electronics of the Istituto Nazionale di Geofisica e Vulcanologia (INGV) in Rome, this autonomous station is formed by a vector magnetometer specifically manufactured by Lviv Institute (Ukraine) for very low temperatures and a low-power system supplied by batteries charged by a wind gener

Résumé :

Late in 1988 the Mt John University Observatory acquired a cryogenic CCD system from Photometrics Ltd (Tucson). The chip is a Thomson CSF TH7882 CDA comprising 384 × 576 pixels. As part of the evaluation process, we have begun two differential photometry programs of the Magellanic Clouds using the Mt John 0.6m Boller & Chivens telescope. On this telescope each CCD pixel corresponds to 0.6 arcsec. Mt John's southerly latitude (44°S) permits year-round observations of the Clouds.The first program concerns B, V and I photometry of five blue eclipsing binaries selected, on the basis of Gaposch

Résumé :

The Darfield moment magnitude (Mw) 7.1 earthquake of September 2010 is the first heavily damaging earthquake to strike New Zealand since the surface wave magnitude (MS) 7.8 Hawkes Bay earthquake in 1931. Although the earthquake has a clear strike-slip surface expression characterised by the Greendale Fault, seismological evidence suggests it is a complex event beginning as a reverse faulting earthquake. Evidence for complexity of the mainshock includes a well constrained epicentre north of the surface fault trace, high near-source vertical accelerations, first-motion and regional moment tensor

Abstract. James Cook's second voyage to the South Seas, undertaken to settle the question regarding the existence or otherwise of the “Great Southern Continent” (Terra Australis Incognita), involved two vessels, the Resolution and Adventure. The Board of Longitude appointed two astronomers from the Royal Observatory, Greenwich, to the voyage, William Wales and William Bayly, respectively, one to each vessel. They were instructed, in addition to their astronomical duties, to observe the height and time of the tides. To this end, Bayly and Wales fabricated tide gauges and conducted timed measure

Abstract Sensitive wide-field observations of polarized thermal emission from interstellar dust grains will allow astronomers to address key outstanding questions about the life cycle of matter and energy driving the formation of stars and the evolution of galaxies. Stratospheric balloon-borne telescopes can map this polarized emission at far-infrared wavelengths near the peak of the dust thermal spectrum—wavelengths that are inaccessible from the ground. In this paper we address the sensitivity achievable by a Super Pressure Balloon polarimetry mission, using as an example the Balloon-borne L

ABSTRACT Recurrent seismic activity in the Koyna region, attributable to the initial impoundment of Shivajisagar water reservoir in 1962 and the subsequent water level variations corresponding to the annual loading and unloading cycles of the Shivajisagar and Warna reservoirs, has continued for the past six decades. To investigate the recurrent seismicity, a 3 km deep scientific borehole was drilled in the Koyna seismic zone. Analyses of downhole geophysical, geochemical and image datasets in the deep crystalline basement provide new and direct information on the physical and mechanical proper

Over 100 data points were acquired in each filter to an estimated precision of 0.02 mag. The flat maxima evident in the light curves suggest that the system, which is currently classed as an interacting candidate, should probably be considered as a detached one. A revised orbital period based on the inclusion of current data is presented. Eclipse timings indicate an eccentric orbit. An apsidal period in the

We searched transiting planet candidates from the MOA-I Galactic bulge data, which have been obtained with a 61cm B&C telescope from 2000 to 2005 for a microlensing search. Although this survey data were dedicated to microlensing, they are also quite useful for searching transiting objects because of the large number of stars monitored (~7 million) and the long span of the survey (~6 years). From our analysis, we found 58 transiting planet candidates. We ar
