Converting Greenhouse Gases to Rocks


One of the ways scientists are attempting to reduce greenhouse gases is to inject these gases into the ground. Specifically, they are testing injecting them, into basalt which is type of igneous rocks usually forming the first (rock) layer (sandwiched between the sedimentary & gabbro layers) in the oceanic crust basalt and in volcanic regions.

The above video features Iceland and its geothermal plants. Iceland is a heaven for geothermal energy as it lies along the Mid-Atlantic Ridge (MAR) (i.e. where Mid-Atlantic ocean floor is spreading apart in opposite directions forming a ridge). Most notably Iceland lies along the V-Shaped Reykjavik ridge (figure below; Google maps) which is part of the Norther MAR.

Radio interference around & Salinity in the Mediterranean


When ESA’s SMOS satellite was placed in orbit in 2009, it transpired that its signal was being interrupted by numerous illegal transmitters around the world. However, by working with national frequency protection authorities, 75% of these transmitters have now been shut down. Nevertheless, this is a laborious process and some regions, such as the Libyan coast and the eastern Mediterranean Sea, remain contaminated where mitigation strategies have not yet been successful. Source: ESA

Thanks to new processing techniques, information from ESA’s SMOS mission can be used to map salinity in the surface waters of the Mediterranean Sea. For example, daily maps can be created using DINEOF, which reduces noise and other sources of contamination. The image, which captures salinity on 3 March 2013, shows the fresher water from the Atlantic Ocean flowing through the Strait of Gibraltar into the Mediterranean Sea. Source: ESA

Computer Simulation of an Earthquake at the Hayward fault in California


An earthquake is the result of a sudden release of “strain” that is built-up between two tectonic boundaries or at a fault line*, usually slipping in opposite directions.

The following video by the California Academy of Sciences shows a computer simulation of an earthquake at the Hayward fault which is one and the most concerning of several faults in California. The most famous fault being the San Andreas fault.

  • A fault is a fracture in the rocks of Earth’s crust. There three main categories of faults: Strike-slip, dip-slip, & Oblique-slip.

The latest earthquake that hit Lebanon [2014-09-01 @ 004136 & 012515]


I have just found out that an earthquake has hit Lebanon. I did not feel it but 7 witnesses have reported the earthquake so far.
Details are as follows:

date: 2014-09-01 (July 06 2014)
time: 235011 / 205011 (Beirut / UTC)
depth: 20 km
epicenter: 41.14°N, 36.08°E (61 km NE of Beirut, 20 km NW of Baalbek)
(moment) magnitude Mw: 4.3
