Global CMT: Special event studies

Here we provide links to the results from special studies of particular sets of earthquakes. Typically, these CMT results use non-standard datasets (e.g., digitized records) or focus on particular earthquake sequences of interest.

• Glacial Earthquakes:
  
  • Source parameters for glacial earthquakes in Greenland occurring in 2006-2010.

  • Haiti:
    The January, 2010, Haiti mainshock-aftershock sequence, including events as small as MW=4.0, and earthquakes occurring prior to 2010 and not previously analyzed.

  • Tohoku:
    The March, 2011, Tohoku foreshock-mainshock-aftershock sequence. Here, we present results from a systematic moment-tensor analysis of the larger foreshocks, mainshock, and larger aftershocks of the 2011/03/11 Off the Pacific Coast of Tohoku MW 9.1 earthquake.

  • Gulf of Aden:
    An unusual swarm of earthquakes in the Gulf of Aden beginning in November, 2010, and continuing into the early months of 2011. We provide results from moment-tensor analysis of 110 earthquakes related to nascent sea-floor spreading in this previously quiescent region.
