What’s up? The Friday links (71) [2015-02-20 09:38:36]  recommend  recommend this post  (41 visits) info

And again it’s almost the start of a weekend! I collected some nice links for you, I hope you like them. Today is Friday and here are your links! The recent Mw 6.0 Wilberforce earthquake in New Zealand has generated a set of landslides. And by writing a set, I mean over 2000. Read this post on a report on all the landslides.   Over 3600 earthquakes have been recorded in Oklahoma since 2009. A recent study finds out that preexisting faults

Kansas M3.6 produces an Intensity 5

People should know that not all earthquakes are the same.  Some earthquakes of larger magnitudes do not produce such an intensity.  This was obviously a shallow thrust, and the town of Anthony was in the hammer zone.  Nobody can take a lot of these without the house falling apart. In the Tulsa World article, it was pointed out that the insurance companies may never pay.  I'm saying they

Oklahoma M4.2 earthquake - shallow and widely felt

Ah, a few more injection wells put on 'Yellow Light'.  I wonder if they are really going to keep up this closing business as the 4's come in fast and furious. Look at that felt area! Oblique normal along the NE megathrust. That whole upper zone is totally disorganized, and still able to pop off these 4+ earthquakes.  I have high hopes if they forget their little restrictions on

M4.0 earthquakes start to shut wells in Oklahoma

Article Wow, and I thought they would get to 5's at least.  The earthquake mechanism has advanced to the point where 4's are an every-day occurrence.  I didn't think they would take action on those.  That would explain why earthquakes have moved further north.  They might not be shutting down a lot of wells, but nobody is going to inject frack waste where there has been an M4.  These

New Texas Injection Zone

I told you it would happen again.  The idiot son decides to mix in surface water (fracking waste) into the salt water injection well, and we get another series of earthquakes. Right now these are poorly located.  They should be right on top of each other.  This is a fine game of Whack-a-Mole, and let's see how big we get.  :) **Remember, if anybody in Texas were honest we'd know how

A moderate (for the UK) M3.8 earthquake occurred last night near Oakham in Rutland, England. The recording above made at the University of Keele on our 6TD seismometer shows the three-components of ground motion (up-down; north-south; east-west) and nicely shows the arrival of P-waves and S-waves. Our record from our SEP-1 school’s seismometer is not

Spain may not be as famous for its earthquakes as Greece, Turkey or Italy, but significant events do shake the western part of the Mediterranean, too. Numerous paleoseismological and archaeoseismological studies as well as research on historical quakes have been undertaken on the Iberian peninsula. A new book was now published by the IGME which collects all the information currently available on the geological effects of earthquakes in Spain. The book is in Spanish and available for free [...]
