Building the underground Singapore - Kuala Lumpur high speed rail (HSR) terminus is likely to be challenging, time-consuming and costly, mainly due to the soft soil conditions prevailing in the area, as acknowledged by civil engineer experts. Despite the difficult soil conditions, typically encountered in many other sites of the country, authorities appear confident that construction of the terminal will be eventually realized. Different soil improvement methods have so far been proposed, and detailed soil investigations will be required before actual construction begins.
On Tuesday a magnitude-7.3 earthquake shook the impoverished country of Nepal, this is the second earthquake to hit the impoverished country in less than a month. On Wednesday, officials with bullhorns walked through the badly damaged streets of Chautara, a small town northeast of Kathmandu, calling for people to leave buildings in danger of collapsing.
In the Buffalo National River, somebody can hear the running water and the next minute the water is gone! In the Ozarks, there are streams that disappear and reappear randomly! The ultimate question is about the reason that the streams become disappeared and the place in which the "disappeared" water goes.
The increase in the frequency of low intensity tremors, originating from the San Andreas Fault, about 10 hours after the magnitude 6 Napa earthquake last August, and an observed increase in two other locations, frequently struck by earthquakes, has set the ground for a comprehensive search for tremors across the state. Watch the video with UC Berkeley seismologist Peggy Hellweg describing how "Tremorscope" a new technology may explain a possible connection between tremors and earthquakes.
What most commuters of Amtrak trains crossing the Hudson River do not have the opportunity to see, was witnessed by U.S. Senator Cory Booker and Amtrak officials. View of the damaged from hurricane Sandy 105-year old rail tunnels was recorded on video, showing the spalling and corrosion on the concrete bench walls. It is estimated that the tunnels have about 20 years of life, before they are shut down for repair works. Replacement of the tunnels is also examined by officials, with total cost being estimated at $20 billion.
The Hawaiian Legislature passed a bill this week setting a goal for the state of reaching 100% renewable power by 2045. If approved by Governor David Ige, Hawaii will be the first state to officially aim for generating all of its electricity from renewable resources. New York and California have had longer standing initiatives to reduce emissions by 2050 below 80% of the levels from 1990, but no bill to date is as ambitious as Hawaii’s.
