Source time function properties indicate a strain drop independent of earthquake depth and magnitude
Earthquakes occur on a broad range of depths and magnitudes, making their origins and impacts difficult to assess. Here, the analysis of 1,700 earthquakes reveals that strain drop is globally invariant, providing constraints on the rupture process and simplifying the task of earthquake damage predictions.

Rapid changes in the electrical state of the 1999 Izmit earthquake rupture zone
Low-resistivity crustal fluids occur near fault zones, but their relation to earthquake generation is unclear. Here, electromagnetic data from the Izmit earthquake reflects the pressure-induced transition between isolated and interconnected fluids that is linked to foreshocks before large earthquakes.

An earthquake gap south of Istanbul
The North Anatolian Fault Zone in Turkey has produced many large earthquakes, however the Marmara region has been inactive and is facing a high probability for a large earthquake. Here, Bohnhoff et al. report on a large seismicity gap in this area with implications for a seismic hazard for Istanbul.

Seismic detection of increased degassing before Kīlauea's 2008 summit explosion
The onset of the ongoing summit eruption at Kilauea Volcano was associated with changes in seismic anisotropy and increased gas flux. This study shows that seismic anisotropy variations are also a function of alterations in stress conditions, and provides a new method for tracking gas flux using seismic observations.
