Earthquake shakes up lunch on Grand Cayman

| 25/11/2020 | 31 Comments

(CNS): A 4.4 magnitude earthquake shook things up a little on Grand Cayman around lunchtime, according to the US Geological Survey (USGS). The tremor was just under 30 miles south of the island about 10 minutes before noon, with George Town being the closest point. Hazard Management Cayman Islands confirmed that they had received some calls from people who had felt the quake but said that no tsunami alert had been issued.

    I definitely felt this. My office chair on wheels was shaking and it lasted about three seconds

      Strange the USGS ENS nor CSEM EMSC earthquake monitor stations did not report any earthquakes in the Cayman Islands. Could it be some serious submarine bombing of Ganga smugglers occurring !. Things that make you go mmm🤔

      Definitely happened. My office has a window so I’m along the outside of the building. The blinds sway and bang into the window frame; I’ll either see/hear that first or feel my own movement/that of my chair/desk depending on how still I am. This time I was still as a statue reading something carefully and I stayed still when I felt the first tremor. My colleague who is on the other side of the building but also in a windowed office on the outside said he didn’t feel anything but probably because he was shaking his leg while sitting at his desk. That’s all it takes to not feel a quake of this magnitude. Moral of the story: just because you didn’t feel it doesn’t mean it didn’t happen.

        11.33am LOL Don’t give up your day job! Only interesting part of post is your colleague shaking his leg… Moral of story:Know what means!LOL

    Upvote this if you felt it

    Downvote this if you didn’t

    I honestly didn’t feel a thing. Not complaining, curious.

    If we’re being honest, HMCI is a mostly untested gov’t cleanup group, not a damage-hardened mitigation, or preventative training/education body, despite its broad mandate. There is no inquisition happening at HMCI, but I’m sure they will be fantastic at distributing water bottles after something bad has happened. It would be nice to offer secondments to professional BGS/NOAA/USGS marine geologists, have them station here for a period with their gear, knowledge, and vocational interest, but that’s not the case. HMCI have not independently sought updated mapping/status of the bathymetry of our neighbouring 20,000ft+ trench, the abyssal unnamed 10,000ft+ mountain-peaks, and seem to be dismissive of potential submarine rockfall, landslides, and/or water displacement tsunami risks. Despite the most active trench activity in 25+ years, they haven’t sought to acquire local seismometers, thought to install a rudimentary local array, nor commissioned any high-level scientific investigation of the source of the increased activity, relying instead on seat-of-the-pants public phone calls and third hand data collected from USGS sensors/technicians in Colorado. Calibrate your expectations accordingly.

    wrong, it was a 5.1 magnitude

      How do you know it was 5.1?

        Given the increased activity in our region, some hobbyists have bought or built their own seismometers this year. DIY Raspberry Pi devices, like “Raspberry Shake”, offer a cheap and wide range of component monitoring. There are others. You can even convert an old unused ipad into a seismograph, using apps that tap into the internal accelerometer sensor, and an ITTT recipe that emails you the data. Sadly, this is lightyears more relevant than HMCI relaying anecdotal stories of concerned citizen phone calls. Not surprisingly, many of our localized minor quakes and aftershocks are not picked up at all by the USGS station 2000 mi away.

          Where do you get this 2000 mile bs? The USGS has stations in Jamaica, Guantanamo, Haiti, Honduras and Yucatan. The Jamaica station was not much farther from the epicenter than George Town was.

      Just looked it up on USGS. It was 4.4 as reported.

      Based on what, the jiggle in your ass? The reported number was 4.4.
