Observational Evidence of a Very‐Low‐Frequency Earthquake (Mw 3.8) Leading to an Earthquake (Mw 4.2): Minto Flats Strike‐Slip Fault Zone, Central Alaska

Geophysical Research Letters
The physical conditions governing earthquake initiation are largely unknown, particularly in the minutes to seconds preceding rupture. While there is geodetic and seismic evidence of precursory activity in the hours to weeks prior to large earthquakes ...

The synchronous occurrence of shallow tremor and very low frequency earthquakes offshore of the Nicoya Peninsula, Costa Rica [PDF]

Geophysical Research Letters, 2013
The occurrence of transient, shallow slow slip at seismogenic zones has important implications for earthquake and tsunami hazards. Here we provide evidence that a tremor and slow slip event occurred at shallow depth offshore of the Nicoya Peninsula, Costa Rica, in August 2008. The temporal coincidence of offshore tremor, very low frequency earthquakes (

Challenges and Opportunities in Multi‐Method Integrated Geophysical Prospection of Buried Building Remains at the Sanctuary of Olympia

Archaeological Prospection, EarlyView.
ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

Studies of seismo-ionospheric correlations using anomalies in phase of very low frequency signal

Geomatics, Natural Hazards & Risk, 2017
We present the results of the statistical analysis of very low frequency (VLF) signal transmitted from NWC transmitter (latitude 21.8° S, longitude 114.15° E) at 19.8 kHz received at Ionospheric and Earthquake Research Centre (IERC) (latitude 22.50° N ...

Whistler Influence on the Overall Very Low Frequency Wave Intensity in the Upper Ionosphere

Journal of Geophysical Research: Space Physics, 2018
We investigate the influence of lightning‐generated whistlers on the overall intensity of electromagnetic waves measured by the Detection of Electro‐Magnetic Emissions Transmitted from Earthquake Regions spacecraft (2004–2010, quasi Sun‐synchronous polar

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Immersive virtual reality as a teaching tool in neuroanatomy: A scoping review

Anatomical Sciences Education, EarlyView.
Abstract Basic core courses in various undergraduate programs, such as neuroanatomy, pose a challenge for students due to the large volume and complexity of the content. In this context, educational technologies such as immersive virtual reality (IVR), which allow students to actively interact with learning materials, offer a complementary pedagogical ...

VIBRATION SENSOR BASED ON FLAT KOIL FOR EARTHQUAKE EARLY DETECTION IN LOMBOK NUSA TENGGARA BARAT REGION

Prisma Sains: Jurnal Pengkajian Ilmu dan Pembelajaran Matematika dan IPA IKIP Mataram, 2013
In this research has been developed the application of flat coil as vibration sensor for early detection of earthquake. The flat coil is a very thin wire winding and acts as an inductor.
