USGS 127 km ... yeah, a reasonably deep event ... that means the amplitude on my seismo would have been even bigger had it been "normal (shallow)" depth !fresh_42 said:Potsdam has 7.0 in 133 km depth. Sounds deep.

Can such deep quakes be felt at the surface in the sense that we should expect damages?davenn said:have upgraded it to M7.1

"M 7.1 Quake Estrn PNG coming in NOW" refers to a magnitude 7.1 earthquake that has occurred in the eastern region of Papua New Guinea and is currently happening at the time of the statement.
The magnitude of an earthquake is measured using a seismometer, which measures the amplitude of seismic waves produced by the earthquake. The magnitude is then calculated using a logarithmic scale, with each increase of one number representing a tenfold increase in the amplitude of the waves.
A magnitude 7.1 earthquake is considered a major earthquake and can cause significant damage and destruction, especially in areas with poor infrastructure. It can also trigger landslides, tsunamis, and other secondary hazards.
The location of an earthquake can greatly affect its impact. Earthquakes that occur in densely populated areas can cause more damage and casualties compared to those in sparsely populated areas. The type of terrain and the depth of the earthquake can also play a role in its impact.
To prepare for earthquakes, it is important to have an emergency plan in place and to regularly practice earthquake drills. It is also important to secure furniture and other objects that could potentially fall and cause harm. Building codes and regulations should also be followed to ensure structures are built to withstand earthquakes.
