Tokyo jolted by 6.1 quake, blackouts but no tsunami warning

quake
A strong earthquake with a preliminary magnitude of 6.1 jolted Tokyo and surrounding areas late on Thursday, stopping train lines and causing sporadic power cuts, but there were no reports of major damage, Japan's public broadcaster NHK said.

The tremor, at 10:41 p.m. (1341 GMT), registered "strong-5" on Japan's intensity scale, a level that could cause some damage to buildings and power cuts, the Japan Meteorological Agency said.

The quake had an epicenter in Chiba prefecture, to the east of the capital Tokyo. There was no danger of a tsunami from the quake, accoring to NHK.

Shallow magnitude 5.9 earthquake hits southwestern Pakistan, kills at least 20

QUAKE
A magnitude 5.9 earthquake struck southwestern Pakistan early Thursday, killing at least 20 people and leaving 300 others injured, according to local authorities.

The quake occurred 15 kilometers northeast of Harnai in Balochistan Province at 3:01 a.m. local time at a depth of 9 km, according to the U.S. Geological Survey. It was followed by a magnitude 4.6 quake in the same area two hours later.

The death toll is feared to rise as people are believed to have been buried under collapsed homes and other buildings. Rescue efforts are reportedly being hampered as roads have become impassable due to landslides.

The Provincial Disaster Management Authority in Balochistan said at least 300 people were brought to hospitals after the quake, including those critically injured.

A stock photo showing lava pouring into the ocean at Kīlauea Volcanic eruption in Hawaii on the Big Island, unrelated to the underwater volcano. Scientists have recorded the largest underwater volcanic eruption of lava, which created a new volcano on the seafloor in the Indian Ocean.
The largest underwater eruption ever recorded has created a volcano on the seafloor that is 2,690 feet tall.

The volcano, which is twice as tall as the Empire State Building, was not present off the eastern coast of the island of Mayotte in the Indian Ocean before an earthquake shook the island 2018.

The underwater seismic event generated over 11,000 detectable earthquakes in what the authors of a Nature paper documenting it describes as a "major magmatic event." The event, which caused the deformation of the seafloor was so great it was registered beyond the Indian Ocean and around the globe.

"Volcanic eruptions shape Earth's surface and provide a window into deep Earth processes," the authors said. "This is the largest active submarine eruption ever documented."
