Earthquakes around the world

M 4.9
93 km NE of Keith, Australia
Time 2021-10-08 18:47:26 (UTC+02:00)
Location 35.451°S 141.010°E

This quake is not huge but given that the strongest recorded quake in South Australia was a M5.6 (1954) and the current political situation in Australia, I thought it was worth mentioning.

Volcanic area

The area in which these earthquakes have appeared as of lately, i have noticed that the area is of volcanic origin (western Victoria)

Last eruption there is assumed to have taken place 2900 BCE, others 5000 years ago. From a geological perspective that is young !

I do of course not know, if the recent rather unusual earthquakes in South Australia have any volcanic connection. It is nevertheless interesting that a wide volcanic area exists in the same region.


Volcano Discovery writes
The voluminous Newer Volcanics province covers a broad 15,000 sq km area of SE Australia with nearly 400 small shield volcanoes and explosive vents of Tertiary-to-Holocene age. Volumetrically the vast proportion of volcanic products consist of flat-lying lava flows, although the most prominent features of the volcanic field are the numerous small scoria cones, tuff rings, and maars that rise above the lava plain.
Several vents were active during the Holocene; another vent (Mount Tower) is now considered to be of late-Pleistocene age. Late-Pleistocene to Holocene eruptions are characterized by small volume and low explosivity, forming a series of scoria cones, maars, tuff rings, and major valley filling lava flows. The youngest dated eruptions took place at Mount Schank and Mount Gambier about 5000 years ago, when explosive activity formed several maars and associated lava flows.
 
When I checked the video of the earthquake that occurred in the northwestern part of Chiba prefecture last night, I would like to introduce how fish and birds react to the earthquake. The brown building on the upper left is #江東区 of #中川船番所資料館 is.#震度5強

Last week saw 1 M7 (M7.3 in Vanuatu) and 2 M6.
In the usual area, there were 4 out of 85 earthquakes equal to or greater than 4.5 and 1904 out of 2430 quakes of all sizes.
Percentage: 78.4%
Last week saw 2 M6 earthquakes, the biggest being a M6.9 in the Vanuatu region.
In the usual area, there were 2 out of 88 earthquakes worldwide equal to or greater than 4.5 and 1846 out of 2214 quakes of all sizes.
Percentage: 83.4%
As usual these numbers are according to the USGS, which means it is very biased to what happens in America. All the earthquakes in La Palma or on Iceland are not included, just to give an example. Iceland had in the week ending the 3rd of October 6100 quakes and something similar could be there for this week, when the figures come out later.

M 6.2 - Hawaii region, Hawaii




Opinion:

Line-1
6.2 Mw earthquake off the coast of #Hawai with a depth of 35 kilometers. Although earthquakes are normal in this part of the Pacific plate, an earthquake of this magnitude is interesting since the new island of Hawaii is forming precisely in this area.#Loihi .
Line-2
#Loihi it is an underwater volcano, it is still debated whether it is a parasitic volcano or a new fissure of the Mauna Loa. This structure is less than 1km deep and is expected to surface in a few tens of thousands of years.
