Oklahoma and a spike of earthquakes

“Oklahoma typically had about 50 earthquakes a year until 2009. Then the number spiked, with 1,047 quakes shaking the state last year.”

This struck me as odd so I mention it. I was looking at the aftershocks in Turkey, poor folks, bitter cold is decending from a high over Russia.

Bob has in the past posted on Tallbloke’s and seems liked so I am providing a link to his request, which might widen his audience slightly.

Station change over time and GHCN V2

Posted: November 7, 2011 by tchannon in climate

Figure 1

The plot shows how the GHCN V2 station location has moved in time as a global average. Hadcrut3 is shown for illustrative purposes only (**).

I computed this some time ago and really needs someone else to carry out the same exercise in case I have made a significant mistake.

“Arecibo radar observations of asteroid 2005 YU55 made in 2010 show it to be approximately spherical in shape. It is slowly spinning, with a rotation period of about 18 hours. The asteroid’s surface is darker than charcoal at optical wavelengths. Amateur astronomers who want to get a glimpse at YU55 will need a telescope with an aperture of 6 inches (15 centimeters) or larger.”


The mess that is GHCN datasets

Figure 1

Figure 1 XY plots two substations for WMO station 48877 where a sane person would reasonably expect a close to straight line with little scatter, since these are supposed to be the same location with very minor differences.

I am deeply critical of professionally managed and published datasets, particularly the withholding of information and lower level data, which makes forensic impossible. There is a lot I am not saying.


X-rated solar region hoves into view

The sun continues bumbling along near solar maximum, my opinion.

Current news is a particular large sunspot region has rotated into view and is doing x-rated flares.

Yesterday the above.

Not much to add, the sun is active.

I am taking this opportunity to fill you in on Tallbloke’s absence.

Some people will say that is not specific enough and major quakes are frequent off Japan, a perfectly reasonable position, nevertheless Alex’s work has a great deal of merit in what is a difficult field. A human lifetime is short in relation to the time between these major events, there is little data.
