"Massive" (7.1) But Fortunately, Deep Earthquake In Columbia

Massive Deep Earthquake Felt All Over Columbia And Ecuador


Earthquake overview : A massive subduction earthquake occurred below the Colombian Andes at 11:31 local time.
Update 18:21 UTC : USGS has changed his Pager color from Green to Yellow, a move we do not like at all. This indicates that there is certainly a chance on fatalities from secondary effects like landslides and Rockfall. We do not expect any shaking fatalities as the max. shaking reported is a V MMI (moderate shaking)
Update 17:52 UTC : The massive earthquake wave is now travelling around the world and will be noticed on every seismograph worldwide. A good example is the below graph at El Hierro, Canary Islands, Spain. The wave departed at the epicenter at 16:31:34 UTC and arrived at El Hierro at 16:42. It took the earthquake wave only 11 minutes to travel this huge distance from Colombia to the Canary Islands* 2 million people are expected to have felt a moderate shaking* 14.5 million people a light shaking and 10 million people a weak shaking. These 3 shaking values are normally NOT generating any damage. Small cracks in walls and falling objects are often experienced though.
