About / How To Use

Quake Watch hopes to bring you details of the more major earthquakes – normally magnitude 6.0 upwards – from around the world. It is not intended to be an alert service and data may be delayed by up to a day before it appears on the blog, however appear it will!

From time to time I will publish reports on earthquakes or seismicity but I would ask you to remember that I am not a geologist or seismologist by way of educational degree thus anything that I express here is purely my own opinion and may or may not be valid. I did however study geology at ‘A’ level back in the days when plate tectonics was a newfangled idea, and I have had a keen interest since. I ask you also to note the attribution and disclaimer notice below.

Because of the huge amount of time it takes to keep all these lists updated and cross match changes in magnitudes and event ID numbers I am changing the way the site works so for a time there will be a mixture of how it is now and how it will be.

Basically all earthquakes event pages are being transferred to posts which has the major advantage that they are categorised. You will be able to find earthquakes all these categories – by year, month (archives), mag 6, mag 7, mag 8, mag 9, upgraded and downgraded and regions. There is a tag cloud as well so where a quake may be categorised as South Pacific the area, for example Tonga, will be in the Tag Cloud. Regions – Categories, Areas – Tags

Eventually the “What was” page will go. On the listings a change will be indicated thus:

2011-03-06 12:31:57, -18.114, -69.390, 6.3, 101.3, Tarapaca. Chile

On the page for the event there will be a button like the ones appearing on the main page.

See new details below (or similar)

All in all when completed this should make it much easier to find an earthquake and to see changes. I hope you like it. 🙂

    Forgive my ignorance, I am relatively new to seismology and this site. Can you tell me WHERE and How I can get information pertaining to a particular earthquake and WHERE and HOW to place it in Quake Watch to allow me to get to the point where I can view the “Arrival Times by City” table? Thank you very much. Sincerely, Edward.

      Are you talking about this site or the QVSData program? USGS have made it more and more difficult to find information and currently the old arrival times table which I extracted for every big quake just is not available anywhere that I can find. In the QVSData program there is the facility to determine the arrival times at a particular seismograph, but only one at a time. You can also get the Phase Arrival Times at a range of seismo station from the technical link on the USGS earthquake page.

    Hello. Is there a place where I can download printable stations maps? Even if I have to use a binder. Thanks. Peter

    I would like to find Bayou Corne USGS helicorder records for the days leading up to Aug. 3, 2012. I can find August 2 on an SSA data page, but am having trouble finding others.

    • PuterMan says:

      I will see what i have and get back to you tomorrow. 02:16 here so I am off to bed!

    • PuterMan says:

      Unfortunately I only started collecting records for Bayou Corne at the end of 2012 – the last 45 days so that is not early enough for your requirement.

      If you look at this web page from IRIS they are showing a data start for 2013

      I believe that is incorrect in light of the fact that I have some 2012 records. I would suggest that you try contacting IRIS to see if they can help you.

      Sorry I am unable to provide you with any data.

    • PuterMan says:

      I just remembered – they were on a different network at the start. I did not collect the data but you can see the recorders on this IRIS metadata page. Scroll down to the LA series.

      You can make a breq_fast request for this data.
