The epicenter of the earthquake
A powerful 7.0-magnitude earthquake has struck the Pacific Ocean near the Kermadec Islands, far north of New Zealand's mainland, seismologists say. Small tsunami waves were observed at a nearby island.

The earthquake, which struck at 1:56 p.m. local time on Thursday, was centered about 195 kilometers (121 miles) southeast of Raoul Island, the largest of the Kermadec Islands, or 1,125 kilometers (700 miles) northeast of Auckland.

The U.S. Geological Survey said the earthquake had a preliminary magnitude of 7.0, down from 7.1 in an earlier assessment. It struck about 22 kilometers (14 miles) below the seabed, making it a shallow earthquake.

Tsunami alerts - which were initially issued for the Kermadec Islands, Fiji, New Zealand and Tonga - were canceled when it was determined there was no longer a threat.

6.3 magnitude earthquake strikes eastern Papua New Guinea

mmmmmmmm
An earthquake measuring 6.3 magnitude on the Richter scale has struck eastern Papua New Guinea.

The European-Mediterranean Seismological Centre (EMSC) said that the epicentre of the earthquake occurred at a depth of 211 km, 456 km northwest of the capital, Port Moresby.

There were no reports of casualties or material damage due to the earthquake.

Papua New Guinea is located along the Pacific Ring of Fire, a region that extends along the coasts of the Pacific Ocean, and is characterised by high activity of earthquakes and volcanoes.

The last earthquake struck northwest of the Kimbe town in Papua New Guinea on Mar 1, with a magnitude of 6.5 without causing material damage or human losses.

A 6.0-magnitude earthquake jolted the southern Philippines on Tuesday (Mar 7), the US Geological Survey said, but there were no reports of casualties or major damage.

The shallow quake struck at about 2pm local time (0600 GMT), a few kilometres from Maragusan municipality in the mountainous gold-mining province of Davao de Oro on Mindanao island.

Shallow earthquakes tend to cause more harm than deeper ones, but local authorities said there were no reports of major damage.

Cherrylyn Dapiton of the Maragusan disaster office confirmed there had been a landslide near a road, but it had not affected anyone or blocked traffic.

New study of earthquakes reveals secrets about the earth's fluid mantle

A new study from a University of Chicago scientist suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle.

The finding was made by measuring the lingering movement registered by GPS sensors on islands in the wake of a deep earthquake in the Pacific Ocean near Fiji. Published Feb. 22 in Nature, the study demonstrates a new method to measure the fluidity of the Earth's mantle.

"Even though the mantle makes up the largest part of Earth, there's still a lot we don't know about it," said Sunyoung Park, a geophysicist with the University of Chicago and the lead author on the study. "We think there's a lot more we can learn by using these deep earthquakes as a way to probe these questions."

Magnitude 6.2 quake strikes Papua New Guinea

mmmmmm
A magnitude 6.2 earthquake struck the remote New Britain region of Papua New Guinea today, the United States Geological Survey said, but no tsunami warning was issued.

The quake had a depth of 38km, the USGS said, and was recorded in the sparsely populated West New Britain archipelago region this morning.

The shaking was felt at a Walindi Plantation Resort near the town of Kimbe about 80km from the quake but it was described by a worker as "not too bad".

"No one really reacted, it shook, but no damage," resort worker Vanessa Hughes told AFP.
