|4/11/2012: Sumatra Quake|
Venus is conjunct the South node. Mars has moved retrograde (backwards) and is now closer to direct opposition with Neptune. (Mars will reach its maximum opposition with Neptune on the 14th when it turns direct.) The Sun is now almost at direct opposition with Saturn. (It will be at opposition on the 15th.) There may be more activity on the 14th/15th, but hopefully most of the stress has been relieved already.
The Moon is near the Galactic Center. The location of the quake is opposite the Moon/GC/Pluto. Sumatra takes the brunt of many disasters because of its location opposite the GC.
Later this month the Sun moves into the trine position with Pluto and Mars, replacing Jupiter's role in March's Mexico and Chili quakes, with the Neptune/Moon's nodes/Mars square still intact.
