Special report: The magnitude Mw8.1 earthquake in Mexico

This is a special report on the magnitude Mw8.1 earthquake in Mexico.

It appears that the reason for the Mw8.1 earthquake in Mexico that part of the plate above the subduction zone broke during this earthquake (?). At the moment details on this is a bit unclear, but earlier research (link) might give more details on this. I did observe this earthquake on all my geophones and this earthquake was seen on Icelandic Met Office SIL stations across Iceland.

Here is how the Mw8.1 earthquake appeared on my geophones. The signal is filtered at 0.1Hz.

There continues to be a high risk for strong aftershocks in this area. At least one or two magnitude 7,0 aftershocks should be expected, but they have not yet happened.

    Quite a few spikes on some SIL stations, I’m guessing there’s a strong nearby quake somewhere not far from Iceland?
