This week in volcano news: Fuego erupts, warning on Kanlaon

Volcán de Fuego, Guatemala

Volcán de Fuego, Guatemala
This week there were several major news stories related to volcanoes. In Guatemala, Volcan Fuego produced a long duration pyroclastic flow which travelled 6 kilometers away from its summit. It stopped only a short distance from a local town.

Meanwhile, in the Philippines, the Phivolcs disaster agency released a special warning regarding the Kanlaon volcano. And, in Alaska, two volcanoes which have each not erupted in about a century produced a several thousand foot tall plume of ash.

This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.


At least five people killed in magnitude 6 earthquake in Iran

People sit by the rubble amidst destruction in the aftermath of a 6.0 magnitude earthquake in Iran's southern Hormozgan province on 2 July.
At least five people were killed and dozens more injured in a shallow magnitude 6 earthquake that shook southern Iran early Saturday, according to an initial report by the state news agency Irna.

According to state television, 49 people were injured in three successive earthquakes that shook the southern province of Hormozgan, including the worst-hit village of Sayeh Khosh.

The first earthquake occurred at about 02:00 local time (21:30 GMT) with a magnitude of 6 at a depth of 16 km, according to the US Seismological Institute (USGS).

It was followed by two other aftershocks, two hours later, with a magnitude of 5.7 and 6, at a depth of 10 km.

According to television footage, several residential buildings collapsed in Sayeh Khosh and the town was plunged into darkness following a power failure.


6.0-magnitude earthquake rattles northern Philippines

An earthquake with a magnitude of 6.0 rattled Cagayan province in the northern Philippines before dawn on Friday, the Philippine Institute of Volcanology and Seismology said.

The institute said the quake, which occurred at 2:40 a.m. local time, hit at a depth of 27 km, about 27 km southeast of Dalupiri Island in Calayan town.

The tremor was also felt in nearby provinces, including Apayao and Ilocos Sur on the main Luzon island. The institute said the tectonic quake will trigger aftershocks but can not cause damage.

The Philippines has frequent seismic activity due to its location along the Pacific "Ring of Fire." (ANI/Xinhua)


This week in volcano news: Supervolcano earthquake swarm - Ebeko erupts

In the last week, an earthquake swam began underneath the dangerous Long Valley supervolcano in California. In less than a week more than 400 quakes occurred at shallow depths. Meanwhile in Vanuatu, the Ambrym volcano is showing signs of unrest and is likely to produce a significant flank eruption in the near future. And, in the Kuril Islands, two volcanoes began new eruptions on the island of Paramushir. This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.


Serious issues with plate tectonics

Geological map of Alaska showing various exotic terranes.
David Pratt's publication in the year 2000 enumerates multiple problems affecting the theory of plate tectonics and seafloor spreading.

The above schematic of Alaska reveals regions of rock strata that appear to have "accreted" to an original craton. Southern Alaska is composed of fragments in all shapes and sizes, each one telling its own tale. They are all "exotic terranes", formed at different places and times. How they were transported to their present location, and why some are rotated with respect to adjoining terranes is a mystery.

Some exotic terranes arrived from regions on the other side of the world, while others are from nearby locations. They are each quite different from one another in their characteristics, representing strata from many so-called "geologic ages". There are deposits from the Quaternary period lying in proximity to those from the Cambrian and Mesozoic periods. Those epochs represent hundreds of millions of years. If the theory of continental movement is correct, then "collisions" between landmasses took place more than a dozen times in Alaska. However, each terrane is not arranged side-by-side with its neighbor, they are intermixed with each other, as the schematic reveals.

Another puzzling aspect to the terrane lithography is that some of it is oceanic crust, while some is continental. Some terranes appear to be from volcanic islands. Others appear to be the remains of continental shelves from South America. Less than one percent of Alaska is thought to be from the "original" North American continent.

In the Journal of Scientific Exploration, Vol. 14, No. 3, pages 307-352, David Pratt took issue with the theory of tectonic displacement of continental and ocean floor structure. As he wrote: "The classical model of thin lithospheric plates moving over a global asthenosphere is shown to be implausible."


Powerful earthquake kills at least 1,150 in Afghanistan (UPDATE)

Taliban officials and residents survey the damage to homes in Afghanistan's eastern Paktika province after a major earthquake.
A powerful earthquake has killed at least 920 people and left hundreds more injured in Afghanistan, Taliban officials have said.

Pictures show landslides and ruined mud-built homes in eastern Paktika province, where rescuers have been scrambling to treat the injured.

In remote areas, helicopters have been ferrying victims to hospitals.

Taliban leader Hibatullah Akhundzada said hundreds of houses were destroyed and the death toll was likely to rise.

Comment: Update June 24

The New Arab reports:
A devastating earthquake in crisis-hit Afghanistan this week resulted in at least 1,150 deaths, according to figures from state media on Friday.

The death toll from a devastating earthquake in Afghanistan continued to climb days after it turned brick and stone homes into rubble, killing 1,150 people and wounding scores more, according to the latest figures carried in state media on Friday.

The country of 38 million people was already in the midst of a spiralling economic crisis that had plunged millions deep into poverty with over a million children at risk of severe malnutrition.

The magnitude 6 quake has left thousands without shelter.

State media reported that close to 3,000 homes were destroyed or badly damaged in Wednesday's earthquake.


This week in volcano news - Canary Islands earthquake swarm - Mount Ibu erupts

Ibu volcano

Ibu volcano
In the last week, an earthquake swam began underneath the dangerous Mount Teide volcano in the Spanish Canary Islands. In only 24 hours, it produced the number of earthquakes typically seen in 6 months at the volcano. Meanwhile in Indonesia, the Ibu volcano produced an unusually large explosion on June 6th. Since then, its eruptive intensity has remained above normal. And, in Alaska, the Davidof volcano experienced a major earthquake which resulted in potentially secondary volcanic earthquakes. This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.


This week in volcano news: Mount Bulusan erupts - Danger at Mount Awu

Mount Bulusan

Mount Bulusan
In the last week, Mount Bulusan in the Philippines unexpectedly erupted, sending a plume of ash to 2,743 meters or 9,000 feet. Numerous volcano tectonic earthquakes have since occurred underneath its summit, meaning that it is likely to erupt again. Meanwhile, in Indonesia, there is now a greatly increased chance that Mount Awu will erupt in the next several weeks due to the detection of harmonic tremor underneath its edifice. And, in Russia, a volcano known for containing one of the planet's rarest minerals unexpectedly began showing signs of unrest through increased sulfur dioxide emissions.

This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.


Magnitude 6.5 earthquake strikes Peru-Brazil border region

An earthquake of magnitude 6.5 struck the Peru-Brazil border region on Tuesday, the European-Mediterranean Seismological Centre (EMSC) said.

The quake was at a depth of 616 km (383 miles) and struck about 111 km south-southwest of Tarauaca, Brazil, EMSC said.
