Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Pulse‐like infrasound accompanying volcanic phenomena sometimes suggests interaction with water at the crater. We focus on pulse‐like infrasound observed at Semisopochnoi Island in the Aleutian Arc, Alaska, during the phreatomagmatic activity on 13 July 2021.

Radiated energy from the mid Niigata, Japan, earthquake of October 23, 2004, and its aftershocks
Radiated energy from the mid Niigata, Japan, earthquake of October 23, 2004, and its aftershocksThe Mid Niigata earthquake of October 23, 2004, is a shallow reverse-faulting event with M-w = 6.6. We analyze transverse component accelerograms of the main shock and four aftershocks (M-w = 4.0 similar to 5.5) recorded at 29 strong motion observation stations. The epicenters of the four aftershocks are located within 5 km from that of the main shock.

Radiated energy from the Noto Hanto, Japan, earthquake of March 25, 2007, and its aftershock
Radiated energy from the Noto Hanto, Japan, earthquake of March 25, 2007, and its aftershockThe Noto Hanto earthquake of March 25, 2007, is a shallow reverse-faulting event with M-w = 6.7. We analyze transverse component accelerograms of the main shock and an aftershock (M-w = 3.6) recorded at 10 strong motion observation stations. The hypocenter of the aftershock is located very close to that of the main shock and the epicentral distances of

Dynamic wedge failure reveals anomalous energy radiation of shallow subduction earthquakes
Earth and Planetary Science Letters, 2013 Abstract Dynamically induced Coulomb failure in the overriding wedge significantly affects energy radiation of shallow subduction earthquakes. For a wedge on the verge of failure, extensive fluid-assisted coseismic failure due to updip rupture causes significant seafloor uplift above a shallow dipping basal fault.

Earth and Planetary Science Letters, 2016 Abstract High frequency energy radiation of large earthquakes is a key to evaluating shaking damage and is an important source characteristic for understanding rupture dynamics. We developed a new inversion method, Image Deconvolution Back-Projection (IDBP) to retrieve high frequency energy radiation of seismic sources by linear inversion of observed

Mapping Apparent Stress and Energy Radiation over Fault Zones of Major Earthquakes
Bulletin of the Seismological Society of America, 2002 Using published slip models for five major earthquakes, 1979 Imperial Valley, 1989 Loma Prieta, 1992 Landers, 1994 Northridge, and 1995 Kobe, we produce maps of apparent stress and radiated seismic energy over their fault surfaces. The slip models, obtained by inverting seismic and geodetic data, entail the division of the fault surfaces into many ...

AIP Conference Proceedings, 2012 The new approach method to determine the magnitude by using amplitude displacement relationship (A), epicenter distance (Δ) and duration of high frequency radiation (t) has been investigated for Tasikmalaya earthquake, on September 2, 2009, and their aftershock.

Teleseismic estimates of the energy radiated by shallow earthquakes
Journal of Geophysical Research: Solid Earth, 1986The energy flux contained in the P‐wave groups (P + pP + sP) or the S‐wave groups (S + pS + sS) radiated by a shallow earthquake is modeled assuming that the energy flux in the direct and depth phases adds incoherently. By defining generalized radiation patterns which incorporate this neutral interference, the wave groups are analyzed as though they ...

Earthquakes: Radiated Energy and the Physics of Faulting
2006Earthquakes: Radiated Energy and the Physics of Faulting is the first book to present a systematic approach to understanding the energy changes associated with earthquakes. Solid Earth scientists, researchers and students -- especially those who work in seismology, tectonophysics, rock mechanics and geodesy -- will find this book an essential resource,
