The swarm of earthquakes in north Leicestershire / south Nottinghamshire continues with another magnitude 2.5 event, again recorded here at Keele. So far there have been several events in the sequence, a couple of previous ones recorded at Keele are in a previous post. Here is the current list from the BGS 2013/02/27 23:57:01.9 52.900 [...]
Small earthquake M2.3 near Caernarfon, Gwynedd, Wales on February 7, 2013. Just on our limit of detectability at Keele, England about 100 miles away. More details from the BGS
A couple of recent UK Midlands earthquakes near Loughborough, Leicestershire. The main shock, magnitude 2.9 (above) occurred at 05:20:44 on January 18 and a magnitude 1.3 aftershock (below) at 11:40:04 on January 21, 2013. The first event was widely felt over a 25km radius, with some reports over 50km away. At 13km depth these are [...]
A magnitude 3.0 earthquake struck north of Chichester, West Sussex at 23:03:03.4 on December 14, 2012. Above is the record from Keele’s seismometer. More details from the BGS.
Earthquake, 2012-12-07 08:18:24 magnitude 7.3 off east coast of Honshu, Japan with small tsunami. Earthquake record from Keele, UK. More details from the USGS
Here is the Keele seismogram for the M7.3 Columbia earthquake of September 30, 2012. As it is a subduction zone earthquake about 150km deep, note the lack of surface waves and consequent limited damage from such an event. More details from the USGS.
Two earthquakes in Northern Italy this morning, showing up well on our helicorder trace at Keele University (above). The larger first event was magnitude 6.0 and has unfortunately caused a number of fatalities. The second 5.2 magnitude aftershock is obviously not quite as distinct. More details from the BBC
Two large earthquakes this morning offshore Sumatra, an 8.6 followed by a magnitude 8.2 a couple of hours later. Fortunately, both strike-slip in mechanism so no significant tsunami. Here are the seismograms from our schools seismometer here at Keele University UK. More details from the USGS here and here.
Back in November of last year I wrote about the travesty that was the UK government’s white paper ‘Natural Choice’ that completely omitted geology from the natural world. Whilst lapses regarding the abiotic component of nature are unfortunately far from uncommon, removing (and it was in an earlier draft) geology, geodiversity and geoconservation from the [...]
On a brief parole from grading gaol … Ian Saginor over at Volcanoclast is hosting this month’s accretionary wedge on the topic of countertop geology. As with many wedges, the geoblogosphere has largely decided to ignore, well at least modify, the brief (probably because we mostly have laminate counter tops). Fortunately, Ian has kindly expanded [...]
Another Stoke-on-Trent earthquake, magnitude 1.8 occurred yesterday (January 19, 2012) provisionally located near the village of Bagnall, similar to the earthquake on January 11. Above is the recording from Keele University. If the location of these two events remain this far east, I may have to revise my initial assessment that they are coal mining [...]
On a whim today, I decided to trace my academic family tree (i.e. my Ph.D. supervisor being my academic parent; their supervisor, my academic grandparent … and so forth). I was stunned to get back to the early 1600s, before the English Civil War, and with some illustrious scientists in my academic heritage line. Ian [...]
Yesterday Stoke-on-Trent experienced a minor, magnitude 2.4 tremor that we picked up on our seismometer at Keele. I think that the official location, near Light Oaks, is a bit too far east as it is almost certainly a former coal mining induced event and the main coal measure sequence is further west. It will be [...]
I have been out the last couple of days undertaking fieldwork for a building stones project, but today I was treated to a glimpse of a gem of a little geological section being prepared. Those of us who work in geoconservation talk a lot about geodiversity but this must be the most geodiverse section I [...]
Photographically 2011 was a poor year for me, most of my better shots were taken on a single photoshoot weekend in Liverpool. After Rock365 in 2010 I was a bit jaded photographically and even when I went out I tended not to take the 5D with me. I experimented with a few iPhone pictures and [...]
I must be mad. In 2010 I misguidedly decided to photograph a rock on each day of the year and project Rock365 was born. And 365 days and photographs later I managed it. It took me a whole year to recover. So, how to better Rock365? The answer is to wait for a leap year [...]
These are some troubling times in British Geoconservation with several geoconservation sites around the country coming under attack from various sources. First, let’s start close to home at Park Hall, Staffordshire. [image: Kidderminster Fm, Park Hall, Staffordshire. source: Ian G. Stimpson] Park Hall is a SSSI (Site of Special Scientific Interest) and National Nature Reserve [...]
With the current interest in El Hierro, the island in the Canaries that is currently experiencing an underwater volcanic eruption, I thought I would post some images from the eruption of volcanic lava into the sea some 330 million years ago. In the picture below, the lava is entering from the right with the background [...]
It’s a while since we had a good meme in the geoblogosphere. Ron Schott has started one running on Anorthosite and Labradorescence. Here is the labradorite sample in the Keele collection from my Rock365 project.
Just back from the field to find that a large earthquake has hit near Van, Turkey. Above is the record from Keele University, UK More details from the USGS
