Bengkulu City has a high liquefaction rate, both geologically and geophysically. This is because consists of rocks in the form sand, silt, mud, clay, coral fragments gravel alluvial areas (Qa) floodplains. Terrace formation (Qat). study aims to analyze potential using seismic waves City, resulting layer profile (Vs) obtained from Vs30 soil classification with potential. was conducted PASI 16S-2...

Urban geophysical exploration plays an important role in the sustainable development of and mitigation geological hazards metropolitan areas. However, it is not suitable to implement active seismic methods densely populated urban The rapidly developing ambient-noise tomography (ANT) method a promising technique for imaging near-surface velocity structure. We selected West Lake area city Hangzho...

The magnitude (MW) 5.5 Pohang, Korea, earthquake on 15 November 2017, induced by the Pohang Engineered Geothermal Systems (EGS) project, caused one fatality and ?US$300 million of economic consequences. Commission, appointed Korean Government to investigate this earthquake, has made public a release data including magnitudes smaller earthquakes associated with well stimulations. On basis popula...

Abstract The velocity structure of the mantle under Baikal Rift Zone (BRZ) is investigated with P‑wave receiver functions (PRFs) for a group 10 seismograph stations. BRZ presents one world’s most active continental rift zones. peculiarities include Cenozoic magmatism in upper southwestern part BRZ, which disappears central and northeastern parts. analysis seismic data reveals other indications ...

The so-called Pelusium Megashear System (PMS), consists of echelon left-lateral megashears crossing Africa from the Nile-Delta since the Precambrian times. Although this system is questioned by some scientists, its existence is supported by others. This research work provides evidences for the existence of the PMS near Egypt’s capital (Cairo city). Evidence is interpreted from gravity, magnetic...

A seismic method (e.g., surfaceor body-wave method) has been often used in pavement engineering to evaluate such critical constructional parameters as the E-modulus and Poisson’s ratio. Conventional method usually uses one or two-channel recording device (e.g., dynamic signal analyzer) for data acquisition whose cost is by no means trivial. In addition, recent applications with the multichannel...

We analyzed strong-motion records at the ground and borehole in around Kanto Basin seafloor Japan Trench area from three nearby offshore earthquakes of similar magnitudes (Mw 5.8–5.9). The were obtained S-net, which was established to enhance tsunami earthquake early warnings after 2011 great Tohoku-oki disaster. MeSO-net, a dense network seismometers installed depth 20 m Tokyo metropolitan are...

An earthquake swarm occurred in Spring 2021 south-central Utah near the town of Milford. The University Seismograph Stations located 125 earthquakes between March 19 and May 10 with magnitudes ranging from 0.5 to 3.2. We implement a matched-filter technique order identify additional that went undetected during routine network location. network-located are used as templates cross-correlated cont...
