Tidal Triggering of Moonquakes

Tidal Triggering Of

Analysis of the tidal stress tensor at the time of moderate to large earthquakes fails to confirm an earlier hypothesis that the origin times of shallow dip-slip earthquakes correlate with solid-earth tidal shear stress, Furthermore, no correlation is seen for either tidal shear stress or tidal normal-to-the-fault compressive stress with shallow strike-slip earthquakes or with deep earthquakes....

Tidal Venuses: triggering a climate catastrophe via tidal heating.

Traditionally, stellar radiation has been the only heat source considered capable of determining global climate on long timescales. Here, we show that terrestrial exoplanets orbiting low-mass stars may be tidally heated at high-enough levels to induce a runaway greenhouse for a long-enough duration for all the hydrogen to escape. Without hydrogen, the planet no longer has water and cannot suppo...

A Simple Physical Model for Deep Moonquakes

Introduction: Deep moonquakes occur between ~750 and 1000 km depth in the Moon and originate at discrete source regions referred to as numbered " clusters. " Occurrence times of events from individual clusters are clearly related to tidal stress [1-8], but also exhibit departures from the temporal regularity this relationship would seem to imply. The physical process that results in moonquakes ...

Tidal modulation and triggering of low-frequency earthquakes in northern Cascadia

We analyze the influence of Earth and ocean tides on the triggering of low-frequency earthquakes (LFEs) in northern Cascadia using three LFE catalogs for southern Vancouver Island and Washington state from episodic tremor and slip events between 2003 and 2013. Sensitivities of LFE families to tidally induced fault normal stress, updip shear stress (UDSS), and corresponding time derivatives are ...
