California earthquake

Oregan was hit by a magnitude 6.3 earthquake off the north-west coast, shaking buildings.

Hitting California at 2.31am local time (10.31am BST) the quake struck at a depth of about 10 km, according to the United States Geological Survey (USGS).

The tremor was recorded around 200 kilometres off the coast of the California-Oregon State border.

Officials have said there was no damage to buildings, and that no tsunami warning has been issued for now.

According to maps issued by the USGS, shaking was felt in the north-west of California, close to the border with Oregan.

The quake struck along the Blanco Fracture Zone or Blanco Transform Fault Zone (BTFZ).

The fault zone runs northeast off the coast of Oregon in the Pacific Northwest of the United States, and reaches from the Gorda Ridge in the south to the Juan de Fuca Ridge in the north.

Officials had warned of an impending earthquake, following increased activity along the Ring of Fire.

A total of 16 significant tremors which measured above magnitude 4.5 were registered along the Ring of Fire on Monday.

They shook Indonesia, Bolivia, Japan and Fiji but didn’t hit the western coast of the US, which lies on the Ring of Fire fault line.

The Ring of Fire is a horseshoe shaped string of 452 volcanoes with high seismic activity in the Pacific Ocean.

Large earthquakes along the deadly ring of fire have devastated the islands of Lombok and Bali in recent days.

More than 300 people died in the earthquakes that hit the Indonesian islands, with nearly a million residents displaced.

Roughly 90 percent of the world’s earthquakes take place along the Ring of Fire.

It covers a massive area from New Zealand to Chile, as well as encompassing the Asian and the American coasts.

Scientists have warned that recent unrest along the ring of fire could lead to a devastating earthquake soon.

Fears centre around a ‘Big One’ which could soon hit California.

Richard Aster, Professor of Geophysics at Colorado State University, recently said: “The earthquake situation in California is actually more dire than people who aren’t seismologists like myself may realise.

“Although many Californians can recount experiencing an earthquake, most have never personally experienced a strong one.

“For major events, with magnitudes of seven or greater, California is actually in an earthquake drought.”
