4.8-magnitude earthquake strikes Death Valley and shakes Las Vegas - at least 8 reported there in 24 hours

quake
Days after Death Valley set a record for the hottest temperature on Earth in more than 100 years, an earthquake hit within the park.

A 4.8-magnitude earthquake shook Death Valley National Park on Wednesday at about 10:30 a.m., park officials reported.

Magnitude measures the energy released at the source of the earthquake, the U.S. Geological Survey says. It replaces the old Richter scale. Quakes between 2.5 and 5.4 magnitude are often felt but rarely cause much damage, according to Michigan Tech.

Satellite imagery shows devastation to US Midwest crops a week after derecho

The storm leveled fields of corn, damaged agricultural buildings and had wind gusts of 80-100 mph in some places


Last Monday, a derecho (widespread windstorm) sped through parts of the upper Midwest. We first wrote about this last Tuesday, after wind gusts in parts of Iowa reached and exceeded 100 miles-per-hour. A week later, 75,000 Iowans are still without power.

The image at the top of the article shows brown scars, meaning that the blown-over crops are dying and are not coming back up. This is a devastating blow, partially because Iowa has led the U.S. in corn production for more than two decades in a row. For so many in the Midwest, this is their livelihood and with fall harvest not that far away.

Millions of acres of corn and soybeans were impacted by the storm, according to the Iowa Soybean Association. The damage is still being assessed, so it's not known exactly how much of the crop is destroyed.

In the middle of summer, unexpected snow blanketed the Baima Snow Mountain Nature Reserve in Deqen Tibetan Autonomous Prefecture in southwest China's Yunnan Province.

The unusual snowfall results from the consecutive rain and decreased temperature. High altitude areas such as the Baima Snow Mountain Nature Reserve has turned into a world of ice and snow.

A pair of powerful earthquakes has rocked the Indonesian coast, measured at 6.8 and 6.9 magnitude, according to the US Geological Survey (USGS), shaking the island of Sumatra.

The two quakes struck off Sumatra's western coast on Wednesday morning, with an estimated depth of 22 kilometers (13 miles) and 26 kilometers (16 miles) respectively. The first tremor impacted an area some 144 kilometers (89 miles) away from Bengkulu, while the second came closer to the city at 130 kilometers (80 miles).

There are no reports of injuries as of yet, however local media said the quakes shook the homes of island residents "as if a truck had passed" and did "minor damage," particularly to buildings with "poor construction."

Sichuan Province in China braces for yet more severe flooding - likely worst for 70 years

Three Gorges Dam braces for 'No. 5 Flood' days after 'No. 4 Flood' struck

Sichuan Province, which sits on the upper reaches of the Yangtze River, on Monday (Aug. 17) braced for some of the worst flooding seen in over 70 years, likely to bring the "No. 5 Flood" downstream to the beleaguered Three Gorges Dam.

After the "No. 4 Flood" of the year passed through the Three Gorges Dam on Saturday (Aug. 15), the Changjiang Water Resources Commission (CWRC) issued an orange flood warning for the Jialing River and its tributary Fu River on the upper reaches of the Yangtze in Sichuan Province on Sunday (Aug. 16). It predicted that the latest bout of flooding will likely form the "No. 5 Flood" of the year and could come only two or three days after the previous one.

The peak of the No. 4 flood on the Yangtze River passed through the Three Gorges Reservoir at around 8 a.m. on the 15th. The water inflow reached 62,000 cubic meters per second, which was higher than the previous three floods this year.

A magnitude 6.6 earthquake struck the Philippines on Tuesday, killing at least one person and damaging roads and buildings including a hospital and a sports complex being used as a novel coronavirus quarantine centre.

It was the strongest earthquake in eight months in the Philippines, which lies on the "Ring of Fire," a seismically active belt of volcanoes circling the Pacific Ocean.

"My things at home fell down and my neighbours' walls cracked and some collapsed," Rodrigo Gonhuran, 30, told Reuters from the central town of Cataingan, which has a population of more than 50,000 people and is near the epicentre.

One man, a retired police colonel, was killed when his three-storey house collapsed, while four people suffered minor injuries, provincial administrator Rino Revalo told DZMM radio station.
