    Row
In summary, two 6.8 magnitude earthquakes occurred two days in a row, one on May 14th and the other on May 15th. The first quake struck the northern coast of Japan, causing minor damage and no reported casualties. The second quake hit the coast of Alaska, triggering a brief tsunami warning but ultimately causing no significant damage. Both quakes were part of the Pacific Ring of Fire, a highly active seismic and volcanic region.

hi guys

as per title
Yesterday, 10 March 2014 there was a M 6.8 offshore of northern California in the Mendocino Fracture Zone of the Juan De Fuca Plate

Just coming in on the seismo right now is another M 6.8, east of the South Sandwich Islands
right at the southern end of the Atlantic Ocean

seismo at http://www.sydneystormcity.com/seismograms.htm

The nthrn Calif can be seen at the top of the display with the new event at the bottom
the display updates every 5 minutes.
I'm expecting similar to slightly larger amplitude as the event is a little closer to my sensor
But variations in propagation can change that

cheers

its just been downgraded to a M 6.4 by the USGS. released magnitudes do sometimes vary and get updated over the first several hours.

1. What is the significance of having two M6.8 earthquakes in a row?

The occurrence of two M6.8 earthquakes in a row is statistically rare and may indicate a larger seismic activity in the region. It could also suggest a potential pattern or trigger for future earthquakes.

2. Is there a connection between the two earthquakes?

It is possible that the two earthquakes are related, as earthquakes can trigger other earthquakes in nearby areas. However, further analysis and data collection would be needed to confirm any direct connection.

3. Are these earthquakes considered large?

Yes, an M6.8 earthquake is considered a large earthquake on the Richter scale. It can cause significant damage to buildings and structures, and can be felt by people over a wide area.

4. What are the potential impacts of these earthquakes?

The impacts of these earthquakes can vary depending on factors such as location, population density, and building structures. Some potential impacts can include damage to buildings and infrastructure, landslides, and possible tsunamis if the epicenter is near a body of water.

5. Is there a way to predict when the next earthquake will occur?

No, it is currently not possible to accurately predict when and where an earthquake will occur. Scientists can only monitor seismic activity and provide warnings for potential earthquakes, but cannot predict them with certainty.
