Bristol Channel Earthquake 20/02/2014

8 months agoAcademics / Geology : Hypo-theses

Magnitude 4.1 earthquake in the Bristol Channel. Seismogram recorded at Keele University. Probably associated with the Bristol Channel Fault System or one of the NW-SE strike slip faults that offset it.

Crete Earthquake M6.4 12/10/2013 Recorded at Keele

M6.4 earthquake strikes 171 km West of Irákleion, Crete, Greece

Pakistan Earthquake September 24, 2013 Recorded at Keele,UK

Today’s September 24, 2013 66km NNE of Awaran, Pakistan Earthquake M7.7 recorded at Keele, UK. Epicentral distance around 55°. More details from the USGS

Panama Earthquake M6.7 13/08/2013 Recorded at Keele, UK

Our ‘schools’ seismometer at Keele is now running the java version of amaseis software (called jAmaseis). The earthquake yesterday south of Panama (13/08/2013 M6.7) is our first real opportunity to play with the event viewer part of the software. The result is here… First impressions are that the event window could be a bit larger [...]

John Milne 1850-1913

John Milne, the so called ‘father of modern seismology’ died 100 years ago today on July 31, 1913. There has been remarkably little fanfare (outside of the Isle of Wight) marking this centenary which is surprising for such a remarkable man. I can’t help thinking that if he had been a physicist or chemist (or [...]

Lleyn Earthquake May 29, 2013 recorded at Keele.

Small earthquake under the Lleyn Peninsula of North Wales early this morning (May 29, 2013) recorded here at Keele University. Magnitude 3.8. About 1.5° distant is about 170km away from Keele. (Blue line is P-wave curve, green is S-wave) More details from the BBC here.

The Leicestershire / Nottinghamshire Earthquake Swarm Continues

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 [...]

Caernarfon, Wales Earthquake February 7, 2013 recorded at Keele

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

Loughborough Earthquakes Recorded at Keele, UK

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 [...]

Chichester, UK Earthquake M3 December 14, 2012 Recorded at Keele, UK.

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.

Japan Earthquake December 7, 2012 Recorded at Keele, UK

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

Columbia Earthquake September 30, 2012 Recorded at Keele, UK

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.

Italian Earthquakes 20 May 2012 Recorded at Keele, UK

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

Sumatran Earthquakes 11/04/2012 Recorded at Keele, UK

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.

Darkest Before The Dawn?

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 [...]

Accretionary Wedge #42 : Countertop Geology

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 [...]

Stoke-on-Trent Earthquake 19-01-2012 M1.8

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 [...]

Standing on the Shoulders of Giants

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 [...]

Stoke-on-Trent Earthquake 11-01-2012 M2.4

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 [...]

Geodiversity

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 [...]
