Tsunami alerts cancelled after Caribbean earthquake

No reports of serious damage coming in.

Interesting. I remember quakes there as a kid in the 50s. My father showed me how to detect the shakes with a half-filled bottle of water on the floor. I also learned the first rule of survival in quakes: Get your shoes on first and then get out. Bare feet and broken china and glass don't go well together.

It looks very similar to events in Iceland when a magma intrusion happened in Grindavik albeit not as powerful or as shallow.

Footage from Bangkok:

Myanmar apparently very badly hit.

Yes that’s my fear. It was very close to Mandalay and shallow.

Large earthquake in eastern Russia but earlier rumours about a tsunami seem unfounded. 

It's the strongest earthquake since the Japan earthquake in 2011.

Two massive earthquakes in that same area in as many weeks. Odd and concerning. 

The previous (magnitude 7.4?) quake may have been foreshock to this one. This latest one was massive and about 25 times bigger than the 7.4 quake (releasing about 125 times the quantity of energy).

hasnt caused much damage despite being shallow,  seems you need at least a 9 to do that.  though perhaps the nature of the seabed and topography mitigated things

Earthquakes are often more complicated than folks realise, multiple shocks over a period of days or longer. But this post allows me to invent a Trumpism. It's the "bigliness" of the quake that is the issue. 😁 My gift to you all is the first rule of survival in a 'quake. Put your shoes on before you do anything else - otherwise you will be running barefoot to safety over broken glass, china and rubble. Never a good idea.

According to a geologist over here (Eamon Doyle) that quake was so massive it was picked up on a seismometer located the west coast here. Impressive and downright scary. 

And you would have thought yourself safe on top of the cliffs - but it was a close thing [video]

A dog walk with a bit of excitement! 😮

Love how the dog just takes massive geological shifts in his/her stride. 

The tremor, which struck shortly after 23:23, was felt across Lancashire and the southern Lake District, including the towns of Kendal and Ulverston, within 12 miles of the epicentre. The quake occurred just off the coast of Silverdale, Lancashire at a depth of 1.86 miles, data suggested. There were no immediate reports of damage.

Beautiful part of the world and friendly people. I have often thought of moving there to live.  But I have no family connections or know anyone in the area.

A magnitude 8 in Europe or the American Northeast (if such quakes are even possible) would absolutely annihilate the place.
