Investigating volcanic hazard in Cape Verde Islands through geophysical monitoring: network description and first results [PDF]
Natural Hazards and Earth System Sciences, 2014 We describe a new geophysical network deployed in the Cape Verde Archipelago for the assessment and monitoring of volcanic hazards as well as the first results from the network. Across the archipelago, the ages of volcanic activity range from ca.

Regional and global variations in the temporal clustering of tectonic tremor activity [PDF]
Earth, Planets and Space, 2014 The temporal distribution of tremor activity exhibits a highly non-Poissonian behavior, and its maximum period of non-Poissonian clustering statistically describes the recurrence interval of major tremor bursts. Here, we examine variations in the temporal clustering properties of tremor activity by assessing their characteristic times, which are ...

Probing Slow Earthquakes With Deep Learning
Geophysical Research Letters, 2020 Slow earthquakes may trigger failure on neighboring locked faults that are stressed sufficiently to break, and slow slip patterns may evolve before a nearby great earthquake.

Creating Flood Disasters: Environmental Memory and Adaptation in Aotearoa New Zealand
Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 2, June 2026.This article explores three questions. First, why does New Zealand have widespread flooding hazards? Second, why are these persistent, with little seemingly learned from the memory of earlier events? And third, beyond reiterating conventional solutions, what examples of alternatives or adaptations are being developed in different places?

Near‐continuous tremor and low‐frequency earthquake activities in the Alaska‐Aleutian subduction zone revealed by a mini seismic array [PDF]
, 2017 Tectonic tremor and low-frequency earthquakes (LFEs) are relatively poorly studied in the Alaska-Aleutian subduction zone due to the limited data availability, difficult logistics, and rugged terrain.

Tidal sensitivity of tectonic tremors in Nankai and Cascadia subduction zones [PDF]
Journal of Geophysical Research: Solid Earth, 2015 AbstractTectonic tremors in subduction zones, which result from slip at the deep plate interface, are known to exhibit a 12.4 h periodicity in their activity, due to tidal influence. Because tidal stress can be calculated quantitatively, the response of the plate interface can yield quantitative information about its frictional property.

AGU Advances, Volume 7, Issue 3, June 2026.Abstract Relative plate motion in subduction zones transitions from frictional slip to viscous flow with increasing depth and temperature. The frictional‐viscous transition can control the depth extent of megathrust earthquakes and episodic tremor and slip (ETS).

Event Size Distribution of Shallow Tectonic Tremor in the Nankai Trough [PDF]
Geophysical Research Letters, 2019 AbstractSlow earthquake size distributions have been found to follow either a power law or an exponential law, depending on the data set. We investigated the size distribution of shallow tectonic tremor events along the Nankai trough, southwestern Japan, observed in 2009, 2015, 2016, and 2018 and estimated the seismic energy radiated during the events ...

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions
Earth and Space Science, Volume 13, Issue 6, June 2026.Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.
