Not related to Louisiana … but …. Holy Cow!!
“Daily earthquakes in Connecticut in the last week have officials scratching their heads and discussing ways the state can prepare for and respond to the next seismic event. In the past seven days, 11 small tremors have been recorded in the Plainfield area. . . “
Many more news stories on it (still happening) if you use search words “Connecticut earthquake”.
WWL – Bayou Corne residents move out after sinkhole settlement
” . . . The Romeros and other plaintiffs in a federal class-action lawsuit against Texas Brine reached a $48.1 million settlement in April. U.S. District Judge Jay C. Zainey ordered all property closings scheduled by Jan. 19 and completed “as soon as practicable.” Plaintiffs’ attorneys and Texas Brine officials said they want them finished by Jan. 30.
Attorneys said they hope to have separate mental anguish claim checks out by January’s end, too.“
” . . . Sediment has completely filled the failed cavern that scientists think breached deep underground and started sucking in surrounding sediment, creating the sinkhole.
However, muck and rock will continue to compress, possibly for many years, making room for more sediment, according to an Oct. 9 report from the state’s special commission on the sinkhole. That could lead to further surface instability but probably not at former levels, experts say.
Micro-earthquakes pointing to breaking rock or salt began to pick up Dec. 22 and have continued for weeks, halting work on the sinkhole and causing cracks in an abandoned sinkhole containment levee, parish officials said.”
we gotta find that Oct. 9 report! – FC
It must be this – Blue Ribbon Commission Summary of Current Ground Stability Understanding and Recommendations [PDF] – sorry we missed it when it came out!
From p.3: “It is clear to the BRC [Blue Ribbon panel] that there are ongoing stability dynamics in the pillars between Oxy caverns 1, 2, 3 and 9, inducing stress changes and salt disturbance that generate micro ‐ earthquakes (MEQs) in that salt volume and pressure changes connected between caverns.“
Page 6 has this interesting point –
“MEQ locations suggest that fracturing is occurring around the Oxy 3 cavern and between the Oxy 1, 2, and 3 caverns. The MEQ magnitudes suggest the scale of this fracturing is on the order of feet to 10s of feet in dimension. The normal, or expected, background level of MEQs for mining and storage operations in this cavern field has not been established and therefore the significance of this activity cannot yet be concluded.“
Translation: They have no clue what all the shaking means.
