An earthquake has occurred at 10:22:33 UT on 5 August 2014 in the Klerksdorp district, the North West province of South Africa. Its hypocenter is located beneath an Orkney town, where more than 10 gold mines exist. The Council for Geoscience (CGS) in South Africa reported that the magnitude and depth was ML5.5 and 4.7 km, respectively. CGS has been...

Three months of acoustic emission (AE) monitoring in a South African gold mine down to MW –5 revealed a newly emergent planar cluster of 7557 events –3.9 ≤ MW ≤ –1.8 (typical rupture radius of 6–70 cm) that expanded with time to reach a size of 20 m on a preexisting geological fault near an active mining front 1 km beneath the ground. It had a shar...

A multi-disciplinary study of the response of the rock mass to mining and mining-induced earthquakes has been conducted in six gold mines in South Africa at sites deeper than 3 km, or with equivalent stress. More than 80 holes (with a total length of more than 2.8 km) were drilled in earthquake-prone areas to locate faults and install instruments....

We conducted a three-dimensional traveltime tomographic reconstruction in and around the source region of the 1984 western Nagano Prefecture earthquake to investigate the generation process for the main shock and associated swarm activity. Up to 220 000 high-resolution traveltime records (2 ms error) were compiled from a dense seismic network. From...

We investigated frequency-magnitude distribution (FMD) of acoustic emissions (AE) occurring near an active mining front in a South African gold mine, using a catalog developed from an AE network, which is capable of detecting AEs down to M W −5. When records of blasts were removed, FMDs of AEs obeyed a Gutenberg−Richter law with similar b values, n...

Results of tomographic inversion enrich our understanding of the geodynamic processes in the Earth. Seismic imaging of fault zones, the shear rupture permits us to investigate the structure under gas storage areas, in districts of large hydroelectric power stations, nuclear plants. The information about the geodynamic evolution of seismic structure...

In order to improve frequency-response estimation in earthquake early warning, we introduce a new source parameter, "frequency-response magnitude (Mres)" that can be calculated for each natural frequency from observed P-wave data using a pre-established attenuation relation. Users can easily estimate frequency responses of their target systems by u...

We propose the method of the elevator operation control for the long-period ground motion using Earthquake Early Warning System (EEWS) and apply this method to the elevator operation control system of the 29-story building of Kogakuin University in the downtown Tokyo, Shinjuku, Japan. First, we estimate the velocity of surface wave that travels th...

We found seismic reflectors aligned along the east side of the volcanic front in northeastern Honshu, Japan, by analyzing seismograms of intermediate-depth earthquakes recorded at High Sensitivity Seismograph Network Japan stations. We identified an unusual high-frequency later phase on the seismograms, which arrives after the direct S waves and co...

Standard least squares method gives the possibility to cope with overdetermined inconsistent systems of linear equations. It is accepted that the more measurements will participate in the general inversion,the better solution will be obtained. However seismic data is special case of geophysical observations, which in practice have a large range of...

We have investigated the spatial variation of the stress field along the fault rupture zone of the 1999 Izmit earthquake (M w 7.4) using first-motion polarity data at seven distinct aftershock clusters. In our approach, the first-motion polarities of all the aftershocks in a cluster are simultaneously inverted to determine the stress tensor paramet...

Automatic pickings in earthquake real-time monitoring systems often contain noise bursts and/or phases of different event(s) occurring almost simultaneously. Typically, a locator uses these picks as P and S waves arrival times coming from a single event and, therefore, should be complemented by a distinctive phase association logic. The method we p...

The Japan Meteorological Agency (JMA) has started the practical service of Earthquake Early Warning (EEW) and a very dense deployment of receiving units is expected in the near future. The receiving/alarm unit of an EEW system is equipped with a CPU and memory and is on-line via the internet. By adding an inexpensive seismometer and A/D converter,...

The real-time earthquake information system (REIS) of the Japanese seismic network is developed for automatically determining earthquake parameters within a few seconds after the P-waves arrive at the closest stations using both the P-wave arrival times and the timing data that P-waves have not yet arrived at other stations. REIS results play a fun...

Horiuchi et al. (2005) developed a real-time earthquake information system (REIS) using Hi-net, a densely deployed nationwide seismic network, which consists of about 800 stations operated by NIED, Japan. REIS determines hypocenter locations and earthquake magnitudes automatically within a few seconds after P waves arrive at the closest station and...

The infamous Tokai Earthquake, which by some accounts is overdue, is expected to be a magnitude >= 8 event that will cause unprecedented damage in regions of Japan. To mitigate hazards from large earthquakes in Japan, an earthquake early warning (EEW) system was developed that is able to determine hypocentral locations from P-arrival data within a...

In general, many earthquakes occur after a destructive shallow earthquake or before a volcanic eruption. It is very important to determine accurate hypocenters as first as possible at a time of such a huge seismic activity, since seismicity data are essential for the understanding of the seismic or volcanic activity. We developed an automatic data...

We have developed an automated system for analyzing Hi-net seismograms for earthquake early warning (EEW) in Japan. Because of limitations imposed by station spacing, our system generally cannot issue an EEW to areas within about 30 km distance of the earthquake's hypocenter. We estimate that about 10 times the number of stations would be needed to...

With the enhancement of regional seismic networks, real-time seismology becomes a practical way for effective damage mitigation. For example, using P-wave arrival times and amplitudes from only a few stations, a real-time earthquake analysis system developed by Horiuchi et al. (2004) can precisely locate the earthquake within a few seconds and issu...

A reliable prediction of the shaking intensity from s-waves is the primary purpose of any earthquake early warning (EEW) system. To date, empirical regression formulae have been used to estimate this intensity from conventional seismic magnitude (e.g.,Mjma), which is the only parameter regarding earthquake size currently broadcast by an EEW. Others...

An M=5 earthquake occurred on September 15, 1998, in the Nagamachi-Rifu fault (NRF), northeastern Japan. In the aftermath of this event, many seismograph stations were constructed temporarily around the fault, forming a dense network of stations with a spatial separation of 5 km. We report here our estimation of the three-dimensional velocity struc...

We have developed an earthquake early warning system (EEWS) by using a spatially dense and high dynamic range seismic network that consists of 700 stations covering the Japanese Islands. The system is able to determine the hypocenter location, magnitude and a shaking intensity parameter within a few seconds from the P-wave arrivals at the closest s...

A fundamental problem in seismology is earthquake location. It is especially important in real-time earthquake warning systems to locate a potentially hazardous earthquake as rapidly as possible in order to sound an alarm in the least amount of time. We have developed a method that uses only the two earliest p-wave arrival times in a seismic array....

Japan is located in one of the most tectonically active region in the world. We have suffered from many disasters brought by earthquakes and tsunamis. Significant efforts to mitigate disasters have been made as one of the most important national programs. Considering the difficulty of the earthquake prediction in time, Japan Meteorological Agency (...

We propose a method to estimate the probability of earthquake growth to a catastrophic one immediately after observing its initiation, for practical usage in an earthquake early warning system. This method is essentially an application of the conditional probability theory, where the magnitude-frequency relation plays a crucial role. We apply it to...

Three-dimensional seismic velocity structure around the Nagamachi-Rifu fault

In Japan, most of the damage caused by large earthquakes is concen-trated within areas less than about 100 km from the focal regions. We have developed an earthquake alarm system that determines earthquake parameters within a few seconds of the P wave's arrival at the closest station, and then transmits the earth-quake information before the S-wave...

3D tomography using P- and S-wave arrivals was performed in a very small area of Tokachi-dake (8 x 6 km2) and two Mt Usu regions:Mt.Usu-1 (40 x 40 km2) and Mt. Usu-2 (140 x 170 km2), Hokkaido in order to investigate magma body changes and volcanic activities before and after the eruption. The high Vp/Vs anomalies greater than 1.97 in Tokachi-dake i...

Three-dimensional seismic velocity structure in the region of the Nagamachi-Rifu fault, which passes through the center of Sendai City, northeastern (NE) Japan, was estimated by travel-time tomography. A low-Vp and low-Vs anomaly was detected close to the surface trace of the fault at depths down to 5 km,, probably due to the existence of thick lat...

Most earthquake damage occurs after arrival of the S wave, whose amplitude is about five times larger than the P wave. Because the P wave travels faster than the S wave, the interval between their arrival times creates an opportunity to activate an earthquake alarm and take preemptive safety measures. We developed an automatic system which transmit...

An extensive seismic network has been constructed nationwide composed of hi-sensitivity seismographic network, broadband seismographic network and strong motion seismographic network. All these data from some 3,000 sites belonging to NIED, JMA and universities are to be accumulated and distributed through NIED to any scientists and engineering thro...

In the present analysis we introduced a calculation strategy of the staggered grid differentiation by using the real value FFT and real inverted FFT for the pseudospectral method and applied the technique to seismic wave simulation. The calculation method introduced here is one third faster on average than the traditional differentiation method by...

We estimated the temperature distribution within the crust of the northeastern Japan arc from P wave velocity perturbations obtained by travel time tomography. By comparing the estimated temperature distribution with the focal depth distribution of shallow, precisely relocated microearthquakes, we found that the brittle to ductile or stick-slip to...

A fine-scale three-dimensional attenuation structure beneath the northeastern Japan arc has been obtained using a joint inversion for source parameters, site response and Q values. Data used for this study are P wave spectra of microearthquakes occurring in the subducting Pacific plate. The subducting plate is found to have higher Q values than the...

Development of new antiatherosclerotic agents were reviewed focusing on ACAT inhibitors and CETP inhibitors. ACAT inhibitors enhance intracellular degradation of VLDL in hepatocytes. Cholesterol absorption in small intestine is inhibited by ACAT inhibitors. Thus, ACAT inhibitors reduce plasma cholesterol levels. In atherosclerotic lesions, ACAT inh...

We have previously shown, using human T-cell lymphocytotrophic virus-I (HTLV-I)-infected cell lines, that soluble interleukin-6 receptor (sIL-6R) is generated through an alternative splicing mechanism. In this study, we examined human sera for the presence of alternatively spliced soluble IL-6R (AS-sIL-6R). We produced a monoclonal antibody (mAb) r...

By using an ELISA, increased levels of the soluble form (sgp130) of gp130, the IL-6 signal transducer, were detected in the sera of various HTLV-1-associated conditions (HC, ATL, HAM) as compared to normal healthy individuals. Sgp130 levels seemed to be correlated with disease severity. The 94 KD of sgp130 was specifically precipitated in the sera...

A P and S wave velocity model is obtained for the crust in the region along the Longmenshan fault zone, Sichuan Province, China, by using data from a refraction profiling survey carried out in this region and those from local earthquakes. 202 local earthquakes along the fault zone are based on this velocity model, location errors being estimated to...

Since ray paths of direct P and S waves are largely distorted in a magma body, a seismic shadow zone is created. However, scattered or diffracted waves with very small amplitudes can arrive in the shadow zone because their ray paths are different from those of the direct waves. They become the first arrival in the shadow zone. More than 100 seismol...

A polymerase chain reaction (PCR) method was used to detect the interleukin-2 receptor alpha-chain (IL-2R alpha) chain which lacks the conventional transmembrane (TM) domain in mRNA from human T-cell leukaemia virus type-I (HTLV-I)-infected cell lines or peripheral blood mononuclear cells (PBMC) isolated from adult T-cell leukaemia (ATL) patients....

We have developed an inversion method for estimating Q structure by the use of a large number of waveform data from earthquakes. We divide an area to be analyzed into small blocks and simultaneously estimate the Q value in each block, source parameters for each event and site response spectrum for each station. The source spectrum is assumed to be...

All disulfide analogs (types I, II and III) of protegrin (PG)-1, an 18-residue antimicrobial peptide having two intramolecular disulfide bonds, were synthesized using regioselective disulfide bond formation. Random air-oxidation of the fully reduced PG-1 formed the type III PG-1. In addition, a type III analog containing an amidated carboxy-termina...

It is well known that there is a large difference in focal mechanism solutions of events even if they occur within a certain small area. Considering earthquake-generating stress to be uniform in a studied area, we developed a new method for simultaneously determining the stress tensor and the orientation of fault planes for many events by the use o...

Spatial distributions of the depths to the Conrad and the Moho discontinuities show that both discontinuities are deep in the middle of the land area and shallow toward the coastlines. The Pn velocity is as low as ~7.5 km/s beneath the land area, while that beneath the Japan Sea and the Pacific Ocean is 8.0-8.2 km/s. It changes abruptly at the tran...

To detect transcripts encoding the interleukin-6 receptor (IL-6R) molecule lacking the transmembrane (TM) domain, in various cell lines and peripheral blood mononuclear cells (PBMC), we used the polymerase chain reaction (PCR) with primer pairs that flank the TM domain and which were selected to generate a 398-bp fragment. We detected 398-bp and 30...

Seven clinical isolates of Shigella sonnei with reduced susceptibilities to fluoroquinolones (sparfloxacin, ciprofloxacin, and ofloxacin) were obtained. The MICs of fluoroquinolones against these S. sonnei strains were 16 to 32 times higher than those obtained against typical strains that are highly susceptible to these agents. The kinetics of [14C...
