We present Submillimeter Array (SMA) Delta *l = 0.88 mm observations of an infrared dark cloud G28.34+0.06. Located in the quiescent southern part of the G28.34 cloud, the region of interest is a massive (>103 M ) molecular clump P1 with a luminosity of ~103 L , where our previous SMA observation...
