After a recent earthquake swarm along the Persian Gulf in Iran, a second deadly earthquake in less than one week shook Iran close to the Iran-Pakistan border in Khash. The 7.8 magnitude quake on April 16, 2013 was the strongest earthquake to hit Iran in more than 50 years, killing at least 46 people in the sparsely populated area and swaying skyscrapers and buildings as far away as New Delhi, India. According to USAToday, Iran’s emergency crew, The Red Crescent, said it was facing a “complicated emergency situation” in the area with villages scattered over desolate hills and valleys.

Meanwhile on the other side of the planet, Oklahoma had six earthquakes within an eight mile radius, and Old Faithful Geyser, Yellowstone National Park, Wyoming rumbled from a second small quake to shake Wyoming over the past week.

Iran EQ Started in Oklahoma

This earthquake activity actually started on the North American Plate in Oklahoma along the prehistoric Craton Plate boundary in the southern USA. The Craton boundary is the location of the North American continental shoreline over 65 million years old, and earthquakes along this ancient southern plate boundary are increasing in Oklahoma, Texas, Arkansas, and along the Gulf of Mexico and Mississippi River Valley.

At 1:45 AM CST, Chandler, Oklahoma split the night with a 3.0 magnitude earthquake, followed 13 minutes later by a 4.6 quake four miles away in Luther, Oklahoma. At 2:15 AM CST, Boley, Oklahoma rattled with a 2.9 magnitude quake, and a 3.3 quake 1 minute later snapped back to Luther. Three hours after that and to the minute at 5:16 AM CST, Luther, Oklahoma had another quake with the highest magnitude so far, registering 4.2.  At 12:06 PM CST, Luther had Oklahoma’s sixth eq of the day, registering 3.5 magnitude.

At 4:46 AM CST, a 3.0 quake rattled Old Faithful in Yellowstone National Park, on the western side of the Craton Boundary. One hour later on the other side of the world, the Earth split at the Iran-Pakistan border with a 7.8 magnitude quake.

Keep an eye on USGS because today has only started.

Cluster Of Earthquakes Shake Iran Near Nuclear Power Plant

April 9, 2013. Within 90 minutes, six large earthquakes struck Iran along the coast of the Persian Gulf next to Iran’s only nuclear power plant. The largest quake registered a 6.3 magnitude, followed by a 5.4 quake, two 4.7 earthquakes, a 4.2, and a 4.8 quake.

Don’t Let the Aftershocks Fool You

Aftershock quakes are dangerous because they are as unpredictable as the initial earthquake. Bigger earthquakes typically have more and larger aftershocks, but don’t let the word aftershock fool you. Aftershocks are still earthquakes even though the word leads us to assume that they are simply less damaging vibrations or the finish-out from a larger earthquake. The Earth’s crust adjusts to the effects of any shock quake, and any Earth shifting, whether an aftershock a foreshock or a main break, is an earthquake that needs to be taken seriously.

We seem to think that the aftershocks are not as dangerous as the main quakes, but this is not always the case. With the recent increase in earthquake magnitudes, aftershocks are better described as “an earthquake cluster or swarm.” Aftershock quakes can be of a large magnitude, which can collapse buildings that are damaged by the main quake, snap bridges, damage nuclear power plants, and demolish houses and other buildings. 

Bridges are constructed in areas prone to natural disasters.

Bridging Over Disaster Zones

Today with the drastic uptick in global earthquakes, it is more accurate, and much more helpful to the surrounding populations, to take the after quakes much more seriously.

The day is not over yet. so be on the look-out for more earthquakes to rattle Iran.
