M 7.6 - 95 km WNW of Hihifo, Tonga 2023-05-10 16:02:00 (UTC) 15.600°S 174.608°W 210.1 km depth A decent event that maxed out my seismo for some minutes https://www.sydneystormcity.com/seismograms.htm As it will disappear off my seismo in around 20 hours ( from time of writing this) a screen...

On 11 March 2020, the World Health Organization (WHO) declared Coronavirus disease (COVID-19) as a pandemic. By then it had spread to at least 110 countries. The announcement made by WHO had a cascading effect. Cities, territories, and countries around the world ended up declaring states of...

So far all I can work out is that the angle of incidence of the outer two and inner two rays is zero degrees, however, I can't work out how to get started on the problem. I feel like I need to use vertical slowness rather than the normal snell's law since I'm working with a dZ rather than a dX...

Good day, I do not fully understand the physical mechanism of formation of Rayleigh waves at the free surface. While their derivation is quite clear and obey free-boundary conditions, it is not clear their physical mechanism. Could you please correct me in my discussion. Incident P-wave can...

Hi guys the last 24 hours has seen 3 large quakes in the SW Pacific area 6.5 central Solomon Isl. not far from Kirakira M 6.5 - 65km NW of Kirakira, Solomon Islands 6.9 southern Kermadec Isl. area M 6.9 - 61km SW of L'Esperance Rock, New Zealand 6.3 Loyalty Isl area E of New Caledonia M 6.3...

Having just read Scientific America's article on the Cascade fault, I wonder if Seismology/Earthquake monitoring sensors could be used to detect fossil fuel reserves and eliminate the use of air-gun blasting that is wreaking havoc on ocean life. Can the oil companies not use naturally occurring...

Homework Statement I am following a textbook "Seismic Wave Propagation in Stratified Media" by Kennet, I was greeted by the fact that he decided to use cylindrical coordinates to compute the Stress and Strain tensor, so given these two relations, that I believed to be constitutive given an...

How can you tell where a dispersed Rayleigh wave train ends...? Is there a way to identify the end of a Rayleigh wave train on the following teleseismic records? The first shows the full surface wave train, the second is zoomed in but cuts off the final part of the original including the last...

Hello everyone, I'm finding Applied Seismology (a comprehensive guide to seismic theory and application) ebook of Mamdouh R. Gadallah... Please help me... I'm really appreciate about that... Thank you and wish all have nice time!

What's Seismology?:rolleyes:

I may be taking control of the running of some seismology equipment, which is run via C code. I know very very little about C code. Would it be better for me to spend the time to thoughroughly learn C, or could it be possible for me to convert the software to Java. I have a pretty god...
