A Second Massive Quake Strikes Nepal

Only a little over a week since the mega-quake in Nepal, a second 7.4 quake has now struck the beleaguered region. After a confirmed death toll of over 8,000 people, misery has been piled on top of misery as another massive quake struck the region just moments ago. This is likely to doom those who were awaiting miraculous rescue, and exacerbate the situation in the already traumatized and crumbled nation.

This quake is another large quake for the subduction zone where the Indian plate collides with the Asian plate. The fault will likely distribute this energy to other parts of the subduction zone, resulting in yet more large quakes and aftershocks.

This fault zone does not lie on the so-called "Ring of Fire" which is responsible for the majority of Earth's seismicity. Rather, this fault is the result of the slow but steady collision of the Indian continent with the Asian continent. Unlike the Ring of Fire, this is the highest fault line on the planet, and therefore capable of some very large quakes.

The last quake caused nearly 30 aftershocks, some over mag 6.0. It is likely the region will experience heavy seismic turbulence and uncertainty in the coming weeks, with the potential for equal or larger quakes.

Anyone who lives near this area should be advised to evacuate, or at the least be ready for more disasters, if they have not been affected already.

If you would like to donate to relief efforts, there are multiple agencies and campaigns. This country will likely need a lot of help in terms of food, clothing, shelter and medical supplies.

Again, it is likely that severe quake activity in this region will continue for some time.
