Haiti Earthquake January 12, 2010 Recorded at Keele

Here is the seismogram of the M7 earthquake in Haiti on January 12, 2010 recorded at Keele University, UK.

This earthquake doesn’t appear to be that well recorded but the P and SS phases are identifiable.

The earthquake was a shallow left-lateral strike-slip earthquake along the Enriquillo-Plaintain Garden fault system, essentially a major component of the plate boundary between the North American and Caribbean plates. The Caribbean plate is moving eastwards with respect to North America by about 20 mm per year.

Much more on the tectonics of the area from Chris Rowan at Highly Allochthonous.

Recorded as part of the UK Schools Seismology project.

  1. Could someone tell me where I can see seismograph records for the days before the earthquake. I was told that there was a lot of activity leading up to the actual event.

    1. It isn’t easy. You might try the USGS website but you would need specialist software to interpret the results. Plus, if you see a signal you don’t actually know it came from Haiti. A much better approach would be to search earthquake catalogues for foreshocks. That being said, I haven’t heard anything about activity leading up to the main shock and a quick trawl of the USGS catalogue at http://neic.usgs.gov/neis/epic/epic_rect.html doesn’t show up anything.

  2. i have several relatives who were also vicitimized by the earthquake in Haiti. thank God that they were not seriously hurt. i hope and pray that Haiti would be able to recover soon from this disaster.
