Tree-ring correlations suggest links between moderate earthquakes and distant rockfalls in the Patagonian Cordillera

Scientific Reports, 2019
Earthquakes with magnitudes M > 7 can trigger large landslides and rockfalls at epicenter distances of up to 400 km, whereas moderate shaking (M = 5–7) is generally thought to result in abundant co-seismic mass movements in the vicinity of the epicenter.

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

Sedimentology, EarlyView.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Seismic Site Effects in Owhiro Bay Quarry, Wellington: Field Observations and Numerical Modelling

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Local topography and geology are well known factors affecting the intensity of seismic shaking. We have investigated the seismic site effects at a site of the Owhiro Bay Quarry in Wellington, New Zealand, using instrumental records and numerical models.

Detecting Snow Avalanche Activity Using Infrasound: Hooker Valley, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Snow avalanches pose considerable hazards to people and infrastructure in alpine environments. Traditional avalanche monitoring relies on meteorological data and visual observations, which can be limited in scope and timeliness. Infrasound offers a promising complementary monitoring tool by detecting the low‐frequency sound waves generated by ...
