Chinese geologists suggest that earthquakes can be triggered by reservoirs in a study of the Zipingpu Reservoir and Longmenshan Slip.

The extended Coulomb failure stress (ECFS) criteria and anisotropic porosity and permeability tensor at micro/meso/macro scale under ultra‑high temperature and pressure (UTP) conditions were developed employing the flow driven pore‑network crack (FDPNC) model under multiple temporal–spatial scales and the hybrid hypersingular integral equation‑lattice Boltzmann method (HHIE‑LBM). The correlation of the Zipingpu reservoir and Longmenshan slip was then analyzed and the fluid–solid coupled three‑dimensional facture mechanism of the reservoir and earthquake fault was explored.

SEOUL, July 17 (Yonhap) — China disclosed a J-10 fighter jet base to the visiting South Korean defense minister last week, a defense official in Seoul said Sunday, a move signaling Beijing’s intent to further strengthen bilateral defense and military exchanges.

South Korean Defense Minister Kim Kwan-jin visited a Chinese air force training base in Changzhou, Jiangsu province, on Saturday, the last day of his three-day visit to China for talks with his Chinese counterpart, Liang Guanglie, the official said.

During his visit to the base, about 200 kilometers south of Beijing, Kim watched the takeoff and landing of a J-10 jet, a China-developed fighter with an operational radius of 1,250 km, before having lunch with Chinese military officers there.

Liang said during his dinner with Kim on Friday that the J-10 jet base has never Read more…

Brazil to build nuclear submarines which will dramatically alter balance of power in South America

Sub: Brazil plans to build its first nuclear submarine in the next few yearsThe Brazilian government has started work on a submarine programme which will include the construction of South America’s first nuclear subs.

The move will boost Brazil’s claim to be the strongest force in the region, and strengthen the country’s military assertiveness.

This new-found power may harm Britain in the event of another flare-up over the Falklands, according to U.S. news agency Global Post, as Brazil thinks the islands should belong to Argentina.

The defence plan was announced in 2008, and will eventually involve the construction of five new submarines. Each will cost around $565 million.

The first, being built in collaboration with a French contractor, is due to come into service in 2016.

By the time the programme is complete, Brazil will Read more…
