[ link to enenews.com] This situation is simply not getting any better. Dr. Horton has reported a “spasmodic burst” which occurred at 1:34 this morning with 90+ micro earthquakes happening overnight. In addition, there were several observable long periods (VLP) events recorded on seismic monitor LA12. Dr. Horton and Dr. Pettit are working to locate the events currently.
We will post updates as information becomes available.Here's a confusing article to try and skim though - [ link to theadvocate.com] Boudreaux said the micro-earthquakes are continuing about every 15 minutes.
He said they are believed to be near the failed cavern that is known as Oxy Geismar No. 3, and not near a second Texas Brine cavern for which structural concerns have also been raised recently.
An earlier round of tremors in late February stopped work directly on the nearly 9-acre surface of the briny, lake-like sinkhole. That prohibition has remained in place, though work had continued around the sinkhole until Wednesday, Boudreaux said.
University of Memphis earthquake researcher Steve Horton reported that the “spasmodic burst” of more than 90 micro earthquakes happened about 1:34 a.m. Wednesday, parish officials reported in the blog post.
The micro quakes have also been called sharp tremors. These kinds of tremors built up last summer before the sinkhole appeared in early August
Since then, they have re-emerged periodically and been linked to rock movement in a zone of collapsed earth along side the section of the Napoleonville Dome where the Texas Brine cavern failed.
Scientists think the cavern was mined too closely to the outer face of the salt dome and had a sidewall failure more than 5,000 feet deep, allowing millions of cubic yards of rock into the cavern.
Scientists think rock is gradually filling the remaining space in the 20 million barrel underground cavern, which, at roughly 2,250 feet long, is the length of the world’s tallest buildings.
Horton also reported Wednesday the detection of different kinds of tremors, known as a very long period events, which have been associated with gas or fluid movement through the collapse zone, parish officials said.
