On June 14, 2011 noticed 2 shallow moderate earthquakes below Northern Sumatra close to Pahae Julu and Pahae Jae. This earthquake was labeled Orange in our daily overview listing (moderately dangerous) as we were not sure about the exact epicenter. The area was relatively remote with a lot of forests. We emphasized however that these kind of shallow earthquakes can create damage in certain conditions.
As we are following regularly the aftermath of  earthquakes, we found out that this earthquake was extremely damaging without making any victims.


The earthquakes (a series of earthquakes with the first one @ 5.5 magnitude) originated in the nearby mapped transform faulting zone.
Transform fault earthquakes are amongst the most damaging for shaking damage and shaking deaths.
Contrary to the preliminary epicenter which was located in the forest, the epicenter location was updated to be now in the valley, along an important road bordered by some villages.

Most affected areas were Pahae Jae District. The earthquake also destroyed homes at the Simangumbang and Purba Tua Districts. Nearly 90 percent of Pahae Jae District was damaged.
At the Simangumban District, 30 houses were destroyed, while at the Purba Tua District, five houses were destroyed. The total number of homes destroyed at the Pahae Jae District could reach as high as 300 units.
Four schools were also damaged.
Due to the damage, more than a thousand residents are forced to sleep in tents set up by the North tapanuli Regency Administration and in emergency tents set up by the residents themselves.

Government aid was delivered one day after the earthquake.
