Earth tremor in La Gomera

There has been a minor earthquake of magnitude 2.1 registered on Tuesday morning, Aug. 3rd 2021, at 03:17 am. The tremor occurred at a depth of 14 kilometres and W-NW of the island's capital San Sebastian de La Gomera at latitude 28.0996, longitude -17.1381. The event was not felt by anyone, but comes as a bit of a surprise because La Gomera is considered volcanically dead, while all neighbouring islands are still active.

 

Closer but insignificant quake off north coast

Just a few days after the locally felt tremor off the north-western coast of La Gomera another seismic tremor averaging just 1,6 (with a peak value of 2,2 mbLg at GOM station) on the Richter scale was registered less than 25 hours ago a short distance off La Gomera's north-north-eastern coast in a depth of 15.2  kms. Quakes of such a minor strenght are inappreciable and happen frequently in and around the Canary Islands, but are rare near La Gomera's coastline. Read more...

A minor earth tremor averaging 2.8 on the Richter scale occurred at a depth of only eight kilometres in the Atlantic very close to La Gomera's west-north-western coast at around 11:10 pm late Tuesday night, January 22nd 2019

This is nothing to worry about, as La Gomera's former volcanoes are long extinct and the island has not experienced any volcanic activity for far more than a million years, being one of the oldest islands in the Canaries. La Gomera existed long before the volcanically very active neighbouring island of El Hierro was even born. However, the abundant seismic activity in and around the Canary Islands rarely comes as close and in such shallow depth as Tuesday night's minor earth tremor.

Generally volcanic activity in the Canaries is of a 'mild nature', but magma movements deep under and around the Canary Islands cause regular tremors. It is however a rare occurrence that such a quake is registered by the seismic station situated in the mountains of the national park with an epicentre so close to La Gomera, and last night's tremors were felt by the population in La Gomera's sparsely populated west and north, see the pointers in the map above, which the show locations of verified reports published by the Spanish National Geographic Institute (IGN). This quake also registered at all seismic stations in neighbouring islands, with the peak value 3.9 having been recorded at the station in La Gomera (EGOM)  a few seconds before 23:10h, at the start of the tremor.

The last minor quake recorded close to La Gomera was recorded in September 2017, see previous post...

Earthquake felt in Tenerife and Gran Canaria

The red star shows the epicentre and the pointers indicate locations where the quake was reportedly felt

A 4.2 magnitude earthquake was felt his morning at 6.36am according to the Spanish National Geographic Institute (IGN). The institute's stations spread across the Canaries registered a seismic movement with its epicentre located in the Atlantic between the islands of Gran Canaria and Tenerife, at a depth of 14.3 kilometres.

The tremors which lasted about one minute were felt in several municipalities of both islands and some people there were woken up by the quake. According the National Geographic Institute’s records, the earthquake reached a peak magnitude of 4.6 within a few seconds of starting. Another three very minor quakes were detected in the same area at between 1.7 and 1.9 magnitude before the stronger one. There were no reports of any damage.

The sea area between these two islands experiences minor earthquakes very regularly and today's slightly stronger one would still be seen as part of normal seismic activity in this area, so please ignore any alarmist reports that some irresponsible media sources have published (e.g. The Express (UK) ran the sensationalist headline: ''TENERIFE EARTHQUAKE: Atlantic smashed by 4.2 magnitude quake near La Palma volcano''.) Yeah La Palma, where doom to 'smash' us all is supposedly brewing below the surface, had to be mentioned again. Sorry but the only word for that headline, and for the La Palma doomsday scenario hype of a few years ago, is BULLSHIT !

Sensationalism: Accident forces hikers to WALK home tonight, possibly due to NO major minor earthquake !

Buses delayed by the accident having discharged hikers, forcing them to go home the last bit ON FOOT !

Scene of the ''sensational'' car crash a short time ago, which led to delays on the main road into Valle Gran Rey just a while ago. There were NO injuries, but the first car is a hired car whose occupants wanted to adhere to the rules of the hire contract before moving out of the way. ''Where's the cops when you need them'' was the local comment. What caused the accident is still under investigation, but I'm sure the Express.co.uk will blame it on the 'swarm' of extremely minor earthquakes on Tenerife soon, just to show how dangerous it is to live or holiday in the Canary Islands and quoting German scientist-cum-doomsayers again (we do get our fair share of them here, too). The printing presses may even erupt from a bullshit overload. The MEGA SENSATIONAL HEADLINE I'd propose: ''Shaken hikers forced to abandon buses  and walk home amid traffic chaos due to breaking, shaking earth - amid traffic chaos in Canaries. Officials in fluorescent vests barely coping while trying to control the fleeing masses' with my image above to prove it.  Anyway, it's all over now...

Minor earthquake close to La Gomera

A minor earth tremor of 2.0 on the Richter scale occurred at a depth of nine kilometres close to La Gomera's north-eastern coast at around 9 pm on Sunday night, Sept. 17th 2017.

This is nothing to worry about, as La Gomera's former volcanoes are long extinct and the island has not experienced any volcanic activity for far more than a million years, being one of the oldest islands in the Canaries. La Gomera existed long before the volcanically very active neighbouring island of El Hierro was even born.

Generally volcanic activity in the Canaries is of a 'mild nature', but magma movements deep under and around the Canary Islands cause regular tremors. It is however a rare occurrence that such a quake was registered by the seismic station situated in the mountains above the town of Agulo with an epicentre so close to La Gomera.
