Earthquakes this week

June 29, 2011

Following the Weather Action warning last week ,

Earthquakes so far this week (23rd – 29th June).

Sun goes quiet again but proton events and heightened risk of earthquake and volcanic activity continues

June 14, 2011

After picking up somewhat in April, the sun has quietened again in May.

Sunspots:

Sunspot numbers

 Radio Flux:

10.7 Radio flux

And,

Astronomers will unveil a “major result” on Tuesday (June 14) regarding the sun’s 11-year sunspot cycle.

The announcement will be made at a solar physics conference in New Mexico, according to an alert released today (June 10) by the American Astronomical Society. The discussion will begin at 1 p.m. EDT (1700 GMT).

In the meantime, 

solar flares and proton events continue signifying a period of heightened volcanic and earthquake activity ——

Piers Corbyn predicts,

 M6+ Earthquakes Indonesia and New Zealand confirm WeatherAction 13-15th June quake risk trial warning.

Two major Earthquakes 13 June M6.0 New Zealand (precede by an M5.5) andM6.4 Molucca Sea Indonesia confirm WeatherAction’s warning issued 22 May for 13-15 June as a period of increased earthquake risk. SEE:

“This 13-15th period”, said Piers Corbyn of WeatherAction.com, “is at the ‘q’ (lesser) level of our now two level forecasts of increased Earthquake risk (trial) around the world compared with other times before and after.  In the upper, ‘Q’, level we expect the biggest increases in seismic activity which also includes notable volcanic eruptions. The last Q period May 31- Jun5th was dramatically marked by the new eruption of the Chile earthquake chain on June 4th as well as associated very extreme weather events”. See http://bit.ly/lFXtsu

The next increased Quake risk period 16-19 June – at the larger, Q, level – follows straight after this one.

 

Further proof that glaciers are not well understood

Glacial armoring

A new paper in Nature shows that glaciers can both help mountains grow as well as cause erosion. The stubborn certainty displayed by Pachauri and the IPCC about glaciers seems all the more ridiculous.

Stuart N. Thomson, Mark T. Brandon, Jonathan H. Tomkin, Peter W. Reiners, Cristián Vásquez, Nathaniel J. Wilson.Glaciation as a destructive and constructive control on mountain buildingNature, 2010; 467 (7313): 313 DOI:10.1038/nature09365

Glaciers can help actively growing mountains become higher by protecting them from erosion, according to a University of Arizona-led research team. The finding is contrary to the conventional view of glaciers as powerful agents of erosion that carve deep fjords and move massive amounts of sediment down mountains. Mountains grow when movements of the Earth’s crust push the rocks up. The research is the first to show that the erosion effect of glaciers — what has been dubbed the “glacial buzzsaw” — reverses on mountains in colder climates.

Glaciers atop mountains in temperate latitudes flow downhill, scouring away the surface of the mountain. Over millennia, such erosion can reduce the height and width of a mountain range by miles. However in very cold climates such as the Patagonian Andes, rather than scraping away the surface of the mountain, the team found that glaciers protect the mountain top and sides from erosion. The team dubs the action of the cold-climate glaciers “glacial armoring.”

“Climate, especially through glaciers, has a really big impact on how big mountains get,” said Reiners, a UA professor of geosciences.
