Update Oct. 1 – 07:30 UTC :
- The village of Timbiqui (Cauca) has been the most affected during this earthquake. 15 to 20 houses have been damaged. The damage was reported rather late as there was no communication and is it was difficult to reach it by road. Timbique is located in the coastal flat area and has apparently a soft soil. Nobody has been reported injured.
- In Cali 2 hospitals reported slight damage as the plaster and parts of the ceiling came down. Some patients were moved to other rooms as a precaution for eventual aftershocks.
- The video below shows the gentle swaying of this earthquake in Cali, Colombia.
Update 21:47 UTC : Colombian reports are maintaining the GREEN status = NO damage or injuries.
Update 20:05 UTC : As expected in the beginning of this article, some minor damage was reported at some official buildings like fallen plaster from walls and ceilings, fallen objects, etc. Nothing really serious that people should leaving the building because of a danger of collapse. We continue to follow up the situation and will report when new reports are being published.
Update 20:01 UTC : The rumor that 2 people were killed in the Esmeraldas province was DENIED by the authorities. This rumor circulated on twitter. There is really nothing reported so far the official said.
Update 18:48 UTC : Good preliminary news from inside Colombia (intermediate report as a lot of villages near the epicenter have still to be visited) : NO serious damage or injuries
Update 18:48 UTC : The Colombia National System of Risk Management had indicated that the earthquake has been felt in the following departments : Cauca, Valle del Cauca, Huila , Risaralda, Quindío, Santander, Antioquia, Caldas, Tolima, Chocó y Cundinamarca.
Update 18:40 UTC : The Colombian Civil defence services (FOPAE) are currently assessing the situation in the many villages closest to the epicenter.
As could be expected people fled to streets when the shaking started (instead of staying inside and following the advise of the specialised services). Running outside to an open space can better be done when the shaking stops.
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
Moderate MMI V shaking : San Agustin 9000 people, Isnos 5000, Saladoblanco 1000, Pitalito 53000, Palestina 2000 and Elias 1000
* 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.
