Front: After an Mw 6.2 earthquake occurred on 14 April 2016 in Kumamoto, Japan, scientists quickly set up a dense seismic array in anticipation of aftershocks. Within two days, they fortuitously captured data from an Mw 7.0 mainshock that reclassified the earlier event into a foreshock. The first author was photographed between the two events at one of the temporary seismic stations, where the damage due to the foreshock is apparent. See Hata et al. (this issue) for the full report.Back: The quality and quantity of seismic stations in Turkey has improved significantly since the 17 August 1999 Mw 7.4 İzmit earthquake, and scientists have produced a number of focal mechanism catalogs covering different time periods, but a homogeneous long-term catalog of moment tensor (MT) solutions has been lacking for this tectonically active region. Cambaz and Mutlu (this issue) present results of a
systematic MT inversion of 133 Mw ≥4.5 earthquakes within Turkey, as shown here, between 2008 and 2015 to provide important new information on the seismotectonics in this region.
