A Deep 7+ earthquake

A tweet from Erik Klemetti today: Wow, that Izu-Bonin earthquake was at a depth of over 600 km? Impressive in size and depth.

When on Saturday evening (local time) skyscrapers swayed, the power went out and trains were stopped in Tokyo, people feared for the worst. The memories of the giant earthquake of March 2011 were still too fresh. Four years ago a huge tsunami inundated the east coast of Japan and caused a partial meltdown of the reactors of the Fukushima nuclear power plant. But after a minute or so of anxiety on Saturday, no tsunami alert was issued and the trains on the Shinkansen lines, Japan's iconic high speed rail, began running again. Although the quake's strength registered with a magnitude of 7.8 - the same as the devastating Nepal event a month ago - only a few injuries and hardly any damage were reported.

When the shaking was over people in Japan continued with their regular weekend business, but seismologists all over the globe looked at the recordings of this earthquake in awe and utter surprise: Saturday's quake was the deepest temblor of its size ever measured.

Heavy Rain in Texas

While California is Still In Severe Drought other US Southern States had last week heavy rain and there is more to come. It's taken nearly a month of nonstop, heavy rainfall, but the entire state of Texas has finally been removed from the worst levels of the U.S. Drought Monitor.

There are still 9 other states, however, where severe drought remains, and those areas are now in the same position as Texans found themselves for several years, hoping for rain.

Kenya's Kibera slum gets a revamp

Kibera, the Kenyan slum infamous for its overcrowding, poverty and lack of sanitation, is getting a major revamp with some modern facilities.




 Founded more than 100 years ago, it is said to be home to around a fifth of Nairobi's population and yet has not featured in any government plans - until recently. The view on slums has changed and the government is now building permanent houses, with proper sanitation. There are now tarred roads, mobile clinics and police stations made from shipping containers, working street lights and even free Wifi throughout the slum.

California's water comes from the north

Perhaps the most fundamental water fact about California is that, historically, water was extremely scarce in the southern two-thirds of the state. The vast majority of precipitation occurs up north, mainly in the winter. So during the 20th century, both the state and the federal government built an elaborate system of canals, aqueducts, and reservoirs to bring water south:
