743 shallow earthquakes, 651 intermediate-depth earthquakes and 281 deep-focus earthquakes (Fig.1). The STFs are first scaled byM_0^{\frac{1}{3}}in time and byM_0^{\frac{2}{3}}in magnitude to remove the moment
Pacific, the deep focus earthquakes which have been detected since 1912 have been concentrated at the north-western end of the Bougainville–New Ireland, and in a region to the south-east of the Santa Cruz Group. Recent research has established a prima facie case for a systematic time–space...
Then the activities of repeaters, catalogs of deep nonvolcanic tremors, shallow VLFEs, and long-term SSEs based on the time series of Global Navigation Satellite System (GNSS) data are all used to understand the interaction of slow earthquakes. They have also been employed to characterize slow ...

The 1952 Tokachi-oki earthquake of M 8.2 and the 1993 Kushiro-oki earthquake of M 7.5, which occurred also off the south-east of Hokkaido along the Kurile Trench, were also preceded by high deep seismicity including large deep-focus earthquakes of the M 7 or over (focal depths 200-600 ...

Numerous instances of damage to the built environment on shallow foundations, such as settlement, tilting, and sinking due to liquefaction, have been witnessed all over the world during many past earthquakes. In the 1964 Niigata (Japan) and 1990 Luzon (Philippines) Earthquakes, most of the damage...
Here we use far-field seismological observations to demonstrate that the rupture properties are consistent with those commonly observed for large deeper earthquakes. In the absence of strong motion sensors in the fault vicinity, we perform numerical predictions of the ground acceleration on a virtual ...
A similar alignment of seismicity was previously reported by Fauzi et al.13, who performed an analysis of earthquakes recorded by local and regional seismic networks. These authors hypothesized that the IFZ serves as a site of focused volatile release into the overlying mantle wedge. Regional ...
Triassic sedimentation in Singapore is represented by the Jurong Group, and overlying Sentosa Group, the former containing the focus of this study; the Pulau Ayer Chawan Formation. The Pulau Ayer Chawan Formation is considered to be Middle Triassic in age, and contains a single member: the ...
