A busy 24 hrs with earthquakes

  • Thread starter davenn
  • Start date
In summary, there has been a burst of earthquake activity in the Loyalty Islands east of New Caledonia, starting with a M 6.8 yesterday and followed by several M5+ aftershocks, including a M 6.1 an hour ago. Additionally, there was a M 6.3 earthquake in the northern Banda Sea, Indonesia. Another aftershock of M 6.6 has also occurred in the Loyalty Islands. Tsunami waves have been detected in New Caledonia and Vanuatu after a 7.0 magnitude earthquake struck, but there is no word on damage. Dave may have graphs detecting the earthquake.

followed by a bunch of M5 + aftershocks, the latest being a M 6.1 about an hour ago at the time of writing this

Dave, please tell the ground to stop shaking. It's considered extremely rude.

it won't listen to me :frown:

there's yet another aftershock coming in as I type this ... a M 6.6 Loyalty Isl, New Caledonia

Tsunami waves have been detected in New Caledonia and Vanuatu after 7.0 magnitude earthquake struck.

Reuters reported the waves hit at 12.35pm (NZT). There was no word on damage.

The Pacific Tsunami Warning Center said waves as high as 1 metre (3.3 ft) above the high-tide mark were forecast to hit New Caledonia and smaller waves were expected in Vanuatu.

I am sure Dave will have his graphs detecting the quake.
 

1. What causes earthquakes?

Earthquakes are caused by the movement of tectonic plates, which are large pieces of the Earth's crust that float on top of the molten mantle. When these plates shift or collide, it can cause the ground to shake and create seismic activity.

2. How do scientists measure earthquakes?

Scientists use a tool called a seismograph to measure earthquakes. This instrument records the vibrations in the ground and produces a graphical representation, called a seismogram, which shows the intensity and duration of the earthquake.

3. Can earthquakes be predicted?

At this time, scientists are not able to accurately predict when or where an earthquake will occur. However, seismic activity can be monitored and warnings can be given to help prepare for potential earthquakes.

4. What is the difference between an earthquake's magnitude and intensity?

An earthquake's magnitude is a measure of the total amount of energy released during the earthquake, while intensity refers to the strength of shaking at a specific location. Magnitude is a quantitative measurement, while intensity is a subjective measurement that can vary depending on distance from the epicenter and other factors.

5. Can earthquakes trigger other natural disasters?

Yes, earthquakes can trigger other natural disasters such as landslides, tsunamis, and volcanic eruptions. This is because the shifting of tectonic plates can cause changes in the Earth's surface and release built-up pressure in other geological features.
