7.7 Magnitude Quake Hits Pakistan

A very large and relatively shallow quake has hit Pakistan today, causing a lot of damage, and fatalities. The quake struck near the country's southern shore, near the town of Parwān, about 173 miles NW of Karachi. The quake was strong enough to be felt throughout the region from India, to Afghanistan, to South Eastern Iran.

The quake occurred along a meandering strike-slip type fault, which has the potential, much like California's San Andreas fault, to generate large quakes up to and possibly exceeding 8.0 in magnitude.

So far at least 5 fatalities have been reported, as well as damage to buildings in the area.

Image of the quake 'shakemap' (legend is at the top of the screen) detailing the strength of the quake in relation to its epicenter.

At this time, at least 5 large-ish aftershocks have struck NNE of the epicenter, ranging from magnitude 4.7 to 5.9. More aftershocks are likely to hit the area for a period of several days to several weeks.

It is also likely that the list of injured or dead may increase as more information becomes available. The area where the quake struck is remote with several large villages nearby, but no major cities, and this is the area where the shaking was most intense. If any significant updates develop, I will update this post.


The quake was apparently powerful enough to cause some land to uplift, and a 30-40ft high island was actually created off of the coast due to the uplift! The island is around 100 feet long, and about one mile off of the coast.

We also know now that the quake has unfortunately killed around 250 people. (correction, the toll is now at around 330 people, and there are approximately 445 injured at this time)... The area is populated densely, but the buildings are not modern in any sense of the word, some being made of stones and mortar.
