Earthquake Thread ~ Always Updated

USGS, GlobalIncident and many others --- none of them list all the quakes that happen. USGS is the worse IMHO. When the Canary Islands were last swarming, the USGS didn't list the quakes until 19 hours later and then only 3 or 4 of the 50+ quakes there had been.

There's too much spectrogram clutter showing for it to be a malfunction imo

Yup, I remember specifically talking about the Canary Islands not showing up on USGS when that happened.

Coffee for all!

This is a huge %

Something is wrong with Chile ...
It's like the significant venting point for global tectonic pressure.
I waiting for it to behave like it has historically, but its not happening...

Omg!! It doesn't even look real.

Chile? well, it looks to me like Ecuador just popped its cork.....

What's that from?!

If the world is broken up according to fault lines & if an area is active it effects the countries in that region. That area in general is behaving differently in frequency and intensity than previously. Japan has been
relatively quiet lately, unlike the past several months.

It's across the board now!

What does this chart mean, sorry but I have never seen it before.

Hi Simple, Thanks and to you Too!

Fyi BUOY Station 56001 - Indian Ocean 1 - 1025km NW of Dampier
in EVENT Mode

This registers events near and far
Real-time data for station TLLS: Seismogram shows a single vertical-component seismogram, and spectrogram, showing the relative distribution of energy between 0 and 10 Hz (bottom to top). Data will nominally be shown for about the last 2 hours, and should auto-update every 1 minute. Timing is in Universal coordinated time (UTC), and is either 4 or 5 hours later than Georgia, depending on daylight saving time. Small clock errors may remain in this station.

These images are normally filtered to retain signal between 0.5 and 2 Hz (band-pass filtered between 2 and 0.5 seconds). This removes some long-period noise, and some building noise. Waveforms are more sensitive to large distant earthquakes.
Note: spectrogram is unfiltered.

Thanks Luis : )

Thanks quirk!!
