SCIENTISTS UNCOVER POTENTIALLY SIGNIFICANT MOVEMENT AT ONE OF AMERICA'S MOST DANGEROUS FAULT LINES
The small island nation of Vanuatu, off the coast of Australia, saw 3 earthquakes strike in the area of Isangel.
The first earthquake struck around 4 a.m. local time on Thursday. It measured a magnitude 5.2 and struck about 47 miles outside the city. Over the next 3 hours, another 2 quakes rattled the same area. One measured a magnitude 4.8, while the other was a magnitude 4.7.
According to the United States Geological Service (USGS), this area of the Australia plate is one of the most seismically active areas of the world.
Further west in the Pacific Ocean, the island of Tonga was rattled by a magnitude 4.6 earthquake. The epicenter of the quake was located about 183 miles west-northwest of Houma, Tonga.

At 9 p.m. local time on Wednesday, a magnitude 4.2 earthquake struck near Lake Louise in Alaska, right outside Denali National Park.
The USGS reported over 230 people felt the shake, including in the city of Anchorage, which is about 114 miles south of the epicenter.
3 earthquakes rattled the Puerto Madero area of Mexico over the last 24 hours.
At 3:08 p.m. local time on Wednesday, a magnitude 4.3 earthquake struck about 49 miles southwest off the Puerto Madero coast in Mexico. This is close to the border between Mexico and Guatemala.
Exactly 9 hours later, at 12:08 a.m. local time, a magnitude 4.4 quake struck in the same area. This was followed by a magnitude 4.5 earthquake in the exact same spot.
Despite the quakes firing off in the ocean, no tsunami warnings were issued.
WHAT DOES EACH MAGNITUDE OF EARTHQUAKE REALLY MEAN?
At 2:26 a.m. on Thursday, a magnitude 5.0 earthquake struck Costa Rica.
The epicenter was measured about 51 miles south-southeast of the capital of San José. The depth of the earthquake was measured to be about 6 miles.
Two earthquakes struck the Alianza Cristiana area of Peru.
On Thursday, around 1:42 a.m. local time, a magnitude 5.3 quake occured about 79 miles west-southwest of the Alianza Cristiana, with a depth of about 6 miles.

SCIENTISTS DISCOVER A NEW WAY TO IDENTIFY WHERE MAJOR EARTHQUAKES COULD STRIKE
At 8:05 a.m. local time on Thursday, a magnitude 4.8 earthquake shook Cliza, Bolivia. The depth of this quake was measured to be about 231 miles deep.
According to the USGS, "The South American arc extends over 7,000 km (4,349 miles). Most of the large earthquakes in South America are constrained to shallow depths of 0 to 70 km resulting from both crustal and interplate deformation."
Around 9:57 p.m. local time on Wednesday, a magnitude 4.3 earthquake rattled parts of Chile.
The epicenter was measured over 53 miles south-southeast of La Tirana, Chile, with a depth of about 76 miles.
The USGS says, "Interplate earthquakes in this region are frequent and often large, and occur between the depths of approximately 10 and 60 km."
Two very minor earthquakes were triggered in the dead center of the Pacific Ring of Fire.
At 7:23 a.m. on Tuesday, a magnitude 2.6 earthquake struck about 12 miles the coast of Hawaii's Big Island, near Pāhala, Hawaii.
About 3 hours later, another quake struck on shore of the Big Island. This was measured as a magnitude 2.5.
