6.0 magnitude earthquake hits Papua New Guinea

mmmm
A magnitude 6.0 earthquake hit Papua New Guinea early Thursday, about 65 kilometres southeast of the town of Kimbe, the United States Geological Survey said.

The quake had a depth of approximately 50 kilometres (31 miles), and struck outside Kimbe, in the West New Britain region, at about 1:13 am (1513 GMT Wednesday), the USGS said.

Deepsea eruption expected off Vancouver Island after 200 Earthquakes in an hour

Scientists believe hot magma will erupt under the Pacific Ocean floor in deep waters off Vancouver Island after they detected up to 200 small earthquakes per hour in the area.

They say the expected rupture about five kilometres deep and 260 kilometres off the coast of Tofino, B.C., will be too distant and small to be cause for concern, but offers a unique opportunity to learn more about how the Earth's crust is formed.

Martin Scherwath, a senior scientist with Oceans Networks Canada, says lava could break through anywhere from weeks to a few years from now, offering the first chance for the phenomenon to be captured by the network's suite of underwater instruments.

The magma is estimated to be about 800 degrees Celsius but will cool rapidly when it hits the ocean water.

He says "almost fluid, runny rock" will come out of the sea floor, solidify and quickly turn black, while the heat causes the water around it to fizz.

Mr. Scherwath says he and fellow geophysicists will be watching to see how much of the Earth's crust is formed with one eruption, while biologists will be most interested in how animals respond to any changes.

Strong mag. 6.0 earthquake - Philippine Sea

bbbbbbb
A very strong magnitude 6.0 earthquake occurred under the sea 91 km (57 mi) from North Sulawesi, Philippines, in the afternoon of Friday, Mar 8, 2024 at 5.11 pm local time (GMT +8).

The quake had a moderate depth of 125 km (78 mi) and was felt widely in the area.

No significant damage or impact is expected from this quake and no particular alert was issued.

Large ingenous events, cosmic impacts and crises in the history of life

Impact
© Randall Carlson Newsletter - March 2024
Last month, in the February 2024 issue of the Kosmographia Newsletter I reported on new research correlating a series of large-scale igneous events which produced the Central Atlantic Magmatic Province (CAMP) and the Siberian Traps with mass extinction episodes. On February 8 another paper was published in the journal Global and Planetary Change which further supports correlations between mass extinction episodes with gigantic volcanic eruptions and catastrophic cosmic impacts. The lead author of the paper is Michael Rampino, who has for decades been in the forefront of researching catastrophic events in Earth history. I have been following his work since the early 1980s and hold him in high regard as a scientist who is willing to think outside established paradigms of Earth history. The abstract to the paper begins:

"We find that Large Igneous Province (LIP) volcanism, mostly continental flood basalts (CFBs), along with the largest extraterrestrial impacts show significant correlations with mass-extinction events in the Phanerozoic geologic record. The ages of the 6 major marine mass extinctions (≥ 40% extinction of genera) of the last 541 MY ̶ the end-Ordovician (~444 Ma), late Devonian (~ 372 Ma), end-Guadalupian (~259 Ma), end-Permian (~ 252 Ma), end-Triassic (~201 Ma), and end-Cretaceous (66 Ma) extinctions are significantly correlated with high-quality U — Pb zircon and 40Ar/39Ar ages of 6 continental flood basalts (CFBs) ̶ the Cape St. Mary's, Viluy, Emeishan, Siberian, CAMP, and the Deccan Basalts.

U — Pb zircon dating (Uranium-lead) is a widely used method for dating metamorphic rocks typically employing a thermal ionization mass spectrometer. Zircon is used because it includes uranium and thorium atoms in its crystalline structure when forming but rejects lead, so any lead found in a zircon crystal is radiogenic, meaning it results from radioactive decay. Argon dating can measure Argon isotopes from a single mineral grain. The ratio of Argon 40 to Argon 39 yields the age of the sample.

The extinctions listed above are considered to be major events in the history of life on Earth. A number of less severe extinctions have taken place, although these events are somewhat more difficult to discern in the geologic/palaeontologic record. Nevertheless, a correlation can be discerned between these extinctions and both volcanic eruptions and cosmic impact.

Shallow 6.3 magnitude earthquake strikes the East Pacific Rise

mmmmmmm
A 6.3-magnitude earthquake struck the East Pacific Rise (February 22) morning, according to the United States Geological Survey.

The natural disaster was located in the southern portion of the mid-ocean rise and centered at a depth of 2.0 kilometers (1.24 miles). The East Pacific Rise, which runs through the Gulf of California in the Salton Sea basin, is located along the floor of the Pacific Ocean and separates the Pacific Plate west from several other plates.

Last week, a 3.8-magnitude earthquake struck California. The natural disaster was located in Ontario and centered at a depth of 13.0 kilometers (about 8.08 miles), according to the United States Geological Survey.

Chile: Magnitude-6.0 earthquake occurs just offshore of far southern Atacama Region

nnnnnnnn
A magnitude-6.0 earthquake occurred just offshore of far southern Atacama Region at around 22:31 Feb. 13. The epicenter was about 83 km (52 miles) west-southwest of Vallenar, Chile.

The tremor occurred at a depth of about 22 km (14 miles), and light shaking was probably felt throughout parts of southern and central Atacama and northern and central Coquimbo regions in Chile and northwestern San Juan Province in Argentina.

There have been no initial reports of damage or casualties as a result of the earthquake, and significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas.

Aftershocks are likely over the coming days. The event has not prompted any tsunami advisories.
