This is just ridicuolus! I can't believe this! We should always monitor earthquakes. SCIENCE! it will always do great things for the human race !

I thoroughly enjoyed listening to this podcast, surely as good as they get - excellent.

My gosh! How awful!Now I know how important Science is!

Dear Sir,
I think that there may be a more diverse way monitor large earthquake activity greater than 7 magnitude. Primarily in the last 6 weeks - 2 months prior to major earthquakes - there can sometimes be a seismic pattern of smaller off-set earthquakes in one particular area. Smaller seismic increases should be monitored at all times.

As in the 26/12/07 Earthquake/Tsunami - Indonesia, there had been a build up of smaller earthquakes/earthquake activity near to the earthquake epicentre area from approximately up to 2 months before the event. Having monitored the earthquake activity prior to the event, on 24/12/07 - (2 days before) I informed a number of people that I thought that there might be a very large earthquake in that area. On 25/12/07 after having monitored N.Indonesia for around 2 months - I definitely thought that there had been a considerable build up of seismicity and was very worried indeed.

On 26/12/07 I turned onto the news and was dumbfounded to find that indeed there had been a terrible earthquake and tsunami in that area. I have not monitored any earthquake activity since that date. I think that constant monitoring of smaller and more frequent earthquake activity in one particular area - is worthwile taking a look at. Tracing back a seismic pattern from around the epicentre area, after earthquake activity could provide useful in future earthquake prediction.

very good pod cast, a little more info on the significance of the 'P' & 'S' waves could have made things a little more interesting. However, the soounds of quakes from distant shores was quite an eye opener.

I beleive that in time we may just find the holy grail to earthquake prediction, but it will take many more years of learning and understanding the very diversity and complexity of the earth.

Professor Chouet's (sizemologist), discovery of the 'Long Period Event' has seemingly provided an excellent preliminary warning system for vulcanology in the prediction of volcanic eruptions allowing for many days advance notice, hopefully this same level of prediction can be acheived for earthquakes.

keep up the good work.

Excellent podcast with Brian and Suzanne.

I have felt a few minor quakes in recent past but to actually hear them speeded up as we heard in the podcast, makes me realise how fragile our planet is, especially if we can detect events of that magnitude from thousands of miles away and hearing the distintive double-bang of the plates moving, sent a shiver down my back.

In regards to the previous post by Julia Hopkins of Cardiff. I believe there is something in early detection before a major event.

Take the recent Haiti 7.0Mw event of Jan 12, 2010. Then look at the quakes within that region, especially along the Plantain Garden fault line preceding the catastrophic event.

If you subscribe to the USGS email updates and select world quakes and select warnings above 3.0Mw. You can receive a stream of emails that can create a pattern.

So, I believe as Julia states, that regular monitoring can give you a warning of larger events to come.

Kind regards,

Karl

Dear Sir I think you have to look at Earthquaks in a different way,I mean way outside the box.This Earth has been doing its thing for millions of years all the evidence you need is there,You just need to think in a differant way,If you can you will save millions of lives.I have e-mailed all sorts of people and papers thay just dont understand. After all it only took 500 years to find out the world wasent flat.

China is setting up a monitoring station in Mt. Everest. Japan has realized that disruption in the ionosphere from electromagnetic field disruption can be a predictor or a precursor to earthquakes. Info. must be shared, because sorry to say there are some evil people who would even cause earthquakes to get rid of populations of people. Think not? It has been said there was not a normal P wave in the tsunami of Indonesia 2004 that killed 230,000 people in Banda Aceh. Nikolai Tesla discovered the technology, and US has been exploiting it since then. Let the investigator beware.

I have just installed and set up my own seismograph and only have to install the thermal shielding to stop temp changes altering the balance. This is something I have wanted to do since I was at school and I have recently just got my bus pass! Try Rockwave.co.uk for info and now hope to enjoy receiving some good data. All you need is a solid concrete floor and a computer running. Perhaps even get some of the rumblings from Iceland and futher afield.

I think I just experienced a small earthquake here in west London. 2 short 'wobbles' at 18.45 approx....Can anyone confirm?? many thanks V Vaughan

There is a Holy Grail but it completely contradicts tectonic theory. Even with a 90% prediction success rate the underlying theory would be instantly rejected by the scientific community. So, as long as tectonic theory exists, prediction of earthquakes is mere pi in the sky. And that is exactly where seismologists should be looking: upwards not downwards.
