The southeast offshore Mie earthquake occurred on April 1, 2016 near the rupture area of the 1944 Tonankai earthquake, where seismicity around the interface of the Philippine Sea plate had been very low until this earthquake. Since this earthquake occurred outside of seismic arrays, the focal mechanism and depth were not precisely constrained using a one-dimensional velocity model, as in a conv...

We continue the investigation of earlier discovered joint acoustic and electric responses near-surface sedimentary rocks on deformation by earthquake seismic waves. The appearance absence this response in earthquakes with energy class more than 11.0, which occurred from June 2017 to May 2021 eastern coast Kamchatka latitude band 51.7-54.0° N, are under consideration. From those we selected 52 e...

For civil protection reasons there is a strong need to improve the inventory of areas that are more vulnerable to earthquake ground motions or to earthquake-related secondary effects, such as landslides, liquefaction or soil amplifications. The use of remote sensing and Geographic Information Systems (GIS) methods along with the related geo-databases can assist local and national authorities to...

Studies on tiny and huge seismic sources using long period surface waves: From the hum to 2004 Sumatra-Andaman earthquake. Abstract Studies on tiny and huge seismic sources using long period surface waves: From the hum to 2004 Sumatra-Andaman earthquake. We study the source processes of two extreme cases, the hum of the Earth and the 2004 great Sumatra-Andaman earthquake, by using long period s...

[1] Clear atmospheric pressure changes associated with the 2003 Tokachi-Oki, Japan, earthquake with Mw 8.3 were recorded with the microbarographs distributed in Japan. The pressure change starts at the arrival of seismic waves and reaches its maximum amplitude at the arrival of Rayleigh waves, suggesting that the observed pressure change was driven by the ground motion of seismic waves passing ...

The combined use of seismic and geodetic observations is now a common practice for finite-fault modeling and seismic source parametrization. With the advent of highrate 1Hz GPS stations the seismological community has recently begun looking at GPS data as a valid complement to the seismic-based methodologies for Earthquake Early Warning (EEW). In the standard approaches to early warning, the in...

S U M M A R Y In many regions of the world characterized by a relatively low rate of seismicity, the determination of local and regional seismic source parameters is often restricted to an analysis of the first onsets of P waves (or first motion analysis) due to incomplete information about Earth structure and the small size of the events. When rare large earthquakes occur in these regions, the...

During earthquake buildings which are closely spaced vibrate out of phase if there is insufficient distance between two adjacent building to accommodate maximum lateral displacement, they collide with each other this phenomenon is called as pounding. Pounding leads to verse damages to structure as the responses are drastically increased in terms of base shear, absolute acceleration, impact forc...

On 24 May 2013, the largest ever-recorded deep earthquake occurred beneath Sea of Okhotsk. A multiple point source inversion procedure is applied to constrain source process of this earthquake, based on waveform modeling of both direct P and SH waves and near-surface reflected pP and sSH waves. Our results indicate that the earthquake consists of six major subevents separated in space and time,...

We retrieve reflected plane waves by applying seismic interferometry to the recorded ground motion from a cluster of earthquakes. We employ upgoing/downgoing P/S wavefield decomposition, time windows, time reversal, and multi-dimensional deconvolution (MDD) to improve the quality of the extraction of reflected waves with seismic interferometry. Because MDD interferometry requires the separation...
