As of December 1st, 2011, we transitioned from our old website to this new one.  This is a completly new look and feel as well as added new features. These new web pages are using a different way of generation and control than we were using before and thus some features from the old may not be implemented.  As we continue with the development of this site we will try to update this page with our progress including known problems and plans.

• 12/1/2011- The old webicorders are now called seismograms and will be using a modified version of the webi2  format.  We may not support the old version with colored lines.
• 12/2/2011- Several of the products available from this new web page are still being served by the old one which has the name old.pnsn.org.  Some of these pages may not work correctly with this new name.  We will be fixing those that are critical.  Most have been  fixed. 
• 12/3/2011- The tremor monitoring map system is still runing but was not yet linked into the new pages at first.  It is now fixed, BUT some links on that page are still broken and some days over late Novemeber, 2011 are missing from the tremor catalog.
• 12/5/2011- We now have a blog section that will be updated from time to time with current interesting information. Comments from interested viewers will be moderated and posted.
• 12/6/2011-  The new Recent Earthquakes page has some really cool features that can allow one to plot different selections of earthquakes at different scales and even make cross-sections and time-depth plots.  However, right now it is only populated with the past few month's worth of data. As we migrate from our old legacy processing system to the new one older events will be filled into this catalog.
• 12/10/2011- Changes in blog layout and connections are made from time to time to improve its look and feel.
• 12/10/2011- Internet Explorer layout issues. Fixed. IE 7 looks decent, 8 and 9 are much better.
• 12/11/2011- A whole new section on Outreach and Discovery is in the works.  It still needs some revising and proofing.  Stay tuned for lots of new information.
• 12/12/2011- We just added an earthqakes search catalog that diplays the queried event data in a table. By default the page will list the last 14 days of events.
• 12/13/2011- Producing time-depth plots, particularly for the volcano pages is being developed.
• 12/16/2011- Some people have noticed that there are more events (including explosions) on our new Recent Earthquakes page than there were in the old web pages before Dec. 1.  This is because the magnitude threshold has been reduced from greater than magnitude 1 to any magnitude.  We also now have a way of plotting (star symbol) known or suspected explosions (from quaries, mines, etc) which the old pages did not have.
• 12/20/2011- Over 100 seismic stations still come into the PNSN in analog form where they are digitized by an old PC-based digitizing system.  Over the past few days there have been many periods of bad noise being generated by this digitial system which has caused many false triggers and degraded earthquake detections and locations.  As of this morning the ailing digitizing board has been replaced and the data are now much "cleaner" which should return us to our optimum operating conditions.
• 12/21/2011- Delays in loading our legacy catalog are cropping up because of difficulties in mapping the old stations (without network codes) into the new database that includes network codes.  We think we have a solution figured out but the full load will probably not be finished before the start of next year.
• 1/3/2012- After the holliday break we are back at getting the old catalog into the database so it can be displayed here and used by anyone.  Other minor changes or bug fixes have been made to improve the response and access.
• 1/4/2012- An earthquake near Lake Chelan this morning had a preliminary magnitude of 3.2 which is considered an "ALERT" earthquake setting off pagers and e-mail notifications to a wide list of interested people.  This was the first test of our new alerting system and it worked fine.  The event occurred at 16:02Z and automatic notification went out at 16:05Z.  It was reviewed and updated to be a M=2.5 event at 16:09 with final complete analysis at 17:47.  We are looking into the reasons why the automatic, preliminary magnitude was clearly too big.
• 1/14/2012 - A small event in eastern Washington yesterday was not properly reported to the operators at the Hanford Reservation.  We have started a very systematic retuning of the alerting mechanism to make sure that this sort of missed event doesn't happen again.
• 1/21/2012-  The alerting mechanism of sending e-mails and pages from real-time systems and the review system has undergone several changes to make it all more robust.  The complexities of reliable notification from the new processing system require careful adjustments and testing since it is far more flexible with more and better information than the legacy system.
• 1/23/2012 - Loading the complete PNSN catalog and waveforms into the new processing system has been delayed farther by the discovery that more than 100 station codes have been found in old pick- and data-files for which we have no meta-data (location information).  We are in the process of tracking down these meta data or determining if these mystery stations have any valuable data.  It seems that at least 3/4 of them were either test stations or mistakes in naming or dead channels.  The rest are stations from neighboring networks that we obtained data from in a one-off manner and thus did not get or save relevant meta-data in a form that propagated to our current system.  We are hopeful that this last 0.001% of the old data will be fixed within a few days so that the intire historical catalog can be loaded.
• 1/25/2012-  An Alert event on the SHZ this morning (M=3.4) was nailed by the automatic system and within a very few minutes reviewed and then finalized with virtually the same magnitude and location.  There were two minor glitches.   Glitch number-1 was that both the NEIC solution and the PNSN solution showed up together on the PNSN web page.  All was correct on the USNSN web page).  Glitch number-2 was the generated ShakeMap included only images without imagemap capabilities to get to the actual ground motions.  This glistch is in the process of being fixed.
• 1/27/2012-  A beta-webicorder system has been developed and under testing to replace one or both of the existing versions (original webicorders  and webi2).  These new ones generate the most recent 12 hours on the fly with caching and previous 24 hour periods in static images.  A new flexible user interface is done and the basic system built.  Testing and optimization for improved performance is under way now.

 

We are about seven weeks into the launch of the new processing system and new web page and things are going very well.   After fixing a few minor glitches with the notification part of the new AQMS system things seem to be functioning well. The new web pages are now running smoothly with some of the information still being provided through a re-direct to the old pages.
