6.7 Mag Earthquake near Makurazaki, Japan (E. China Sea)

In summary, a strong 7.0-magnitude earthquake struck off the southwestern coast of Japan, with the epicenter located 160 kilometers from Makurazaki. No major damage was initially reported, though several small tsunamis were reported on two islands. The USGS initially reported a 7.0 magnitude, followed by a 6.5, but later revised it to a single 6.7 event. The earthquake was felt in nearby cities and a raw seismogram showed the intensity of the quake. We hope for the safety of those in the affected areas and will keep an eye out for updates.

Strong 7.0-magnitude quake hits off Japan coast: USGS
http://news.yahoo.com/strong-7-0-magnitude-quake-hits-off-japan-211816995.html
A powerful 7.0-magnitude earthquake struck off the southwestern coast of Japan early Saturday, the US Geological Survey (USGS) said, with Japanese authorities reporting several small tsunamis on at least two islands.

The USGS put the epicentre of the shallow quake about 160 kilometres (100 miles) from the town of Makurazaki in southwest Japan, though no major damage was initially reported.

yes, initially reported as a 7.0 followed by a 6.5 30 sec later, was revised down to a single 6.7 event after around 30 mins

raw seismogram from my sensor...

Wow, that's a pretty big earthquake. I hope everyone in the affected areas is safe and that there isn't too much damage. It's always scary when natural disasters like this happen. I'll definitely keep an eye out for any updates on the situation.
 

Related to 6.7 Mag Earthquake near Makurazaki, Japan (E. China Sea)

1. What caused the 6.7 magnitude earthquake near Makurazaki, Japan?

The earthquake was caused by the movement of tectonic plates in the Earth's crust. The area where the earthquake occurred is part of the Pacific Ring of Fire, where many earthquakes and volcanic eruptions happen due to the convergence of several tectonic plates.

2. How was the magnitude of the earthquake determined?

The magnitude of an earthquake is determined by using seismographs, which record the seismic waves produced by the earthquake. These recordings are then analyzed to determine the strength or magnitude of the earthquake on the Richter scale.

3. Was there any damage or casualties from the earthquake?

At this time, there have been reports of minor damage to buildings and infrastructure, but no reported casualties. This is likely due to Japan's strict building codes and earthquake preparedness measures.

4. Are aftershocks expected after a 6.7 magnitude earthquake?

Yes, aftershocks are common after a large earthquake. These are smaller earthquakes that occur in the same area as the initial earthquake and can continue for days, weeks, or even months after the initial event.

5. Is there a way to predict when and where an earthquake will occur?

Unfortunately, there is currently no reliable way to predict when and where an earthquake will occur. Scientists continue to study earthquake patterns and try to improve prediction methods, but as of now, it is not possible to accurately predict earthquakes.
