A moderately strong earthquake shook Mexico's Pacific coast resort of Acapulco on Wednesday, sending people fleeing into the streets. No damages or injuries were reported.

The magnitude-5.8 quake occurred at 8:24 a.m. local time (1324 GMT) and was centered about 85 miles (138 kilometers) east of Acapulco, the U.S. Geological Survey reported on its website.

The quake occurred at a depth of nearly 6 miles (10 kilometers).

US: Swarm of Tiny Earthquakes Stretches From Belfast to Bucksport

Searsport, Maine - As many as 30 tiny earthquakes have been detected over the last few days in the area between Belfast and Bucksport, but geologists say there's no cause for alarm.

"Microquakes is what we call them," Henry Berry, a bedrock geologist with Maine Geological Survey, said in a phone interview Tuesday afternoon. "Unless you were right there, you wouldn't notice them."

But plenty of people have been noticing, Searsport Police Chief Dick LaHaye said Tuesday afternoon, just minutes after he dispatched an officer to Savory Road, where a resident had called to inform authorities about another earthquake.

They've responded to calls about gunshots and shotgun blasts, calls from people who felt their feet vibrate along with the earth and calls about things falling off shelves - all of which were determined to be related to the earthquake, he said.

"We'll continue to investigate," LaHaye said. "There's obviously something going on. It's outside of the police purview at this point, but we'll continue to respond to any and all calls that come in."

The quakes have all measured less than 2 on the Richter magnitude scale, according to a press release from the Maine Department of Conservation. On that scale, the threshold at which damage can occur is magnitude 5.

US, Texas: Smaller Earthquakes Could Mean A Large One Is Coming

Four Earthquakes Border Region In One Week

In the past week, the El Paso region has had four earthquakes at least 4.2 in scale. Seismologist Aaron Velasco tells KFOX14 the earthquakes could foreshadow a large scale earthquake in El Paso.

These earthquakes all happened in a remote area of Chihuahua, Mexico. They were still pretty close to the U.S. border.

Most El Pasoans KFOX 14 spoke with said they never worry about earthquakes because they don't think we're on a fault line. Velasco said the mountains in El Paso are proof that we are on one or more fault lines. "The hazard is not zero here in El Paso," said Velasco. "It's low compared to California and Japan, but at any particular time that means that we could have an earthquake."

Emergency services and Red Cross experts told us that the best thing El Pasoans can do is to prepare themselves for an earthquake. They recommend keeping a go-bag, or emergency kit with things like: AM/FM radio, flashlight, fresh batteries, bottled water, a first-aid kit, and even a whistle in case you get trapped somewhere.

Mexico: Second earthquake in one week recorded in Northern Chihuahua

A 4.3-magnitude earthquake was recorded just before 5:45 a.m. Monday 34 miles southwest of Sierra Blanca in Chihuahua, Mexico, according to the U.S. Geological Survey.

The earthquake occurred days after another tremor was recorded in Chihuahua about 40 miles south of Fort Hancock. That quake also registered a 4.3 magnitude on the Richter scale.

Philippines: 5.0 Magnitude Earthquake Rocks Mindanao

A moderate earthquake measuring 5. 0 on the Richter scale rocked the southern Philippine region of Mindanao Sunday evening, US seismologist said.

There was no immediate report of casualties or damage from local authorities.

The United States Geological Survey (USGS) said the quake, which struck at 7:06 p.m. local time (1106 GMT) at a depth of 78.6 kilometers, was traced 158 kilometers southeast of Davao, Mindanao, or 1105 kilometers southeast of Manila, the country's capital.

The Philippines sits in the so-called Pacific Ring of Fire, an area where continental plates collide producing frequent quakes and volcanic activities.

Magnitude 5.4 earthquake hits Kazakhstan - USGS

A magnitude 5.4 earthquake was recorded in eastern Kazakhstan on Sunday, the U.S. Geological Survey said.

The epicentre was 71 km (44 miles) northeast of Kazakhstan's largest city, Almaty, at a depth of 20 km (12.4 miles), the geological survey said on its website, www.usgs.gov.

Reuters reporters in Almaty felt buildings shake for several seconds, but there were no immediate reports of damage.

Just after 7am on Saturday 30th April 2011, Christchurch was shaken by a 5.2 aftershock. This was centered 65 kilometers from the city center.

Christchurch continues to experience aftershocks as the national state of emergency in New Zealand draws to a close. As from May, the Christchurch Earthquake Recovery Authority (CERA) will take over the planning and recovery process in the city.
Another Large Aftershock Felt in Christchurch

At 7:08am on Saturday 30th April, Geonet recorded a 5.2 aftershock in the Christchurch region. It released 879 tons of energy and was rated as 6 on the Mercalli scale. This rating describes potential effects as follows: "Felt by everyone. Difficult to stand. Some heavy furniture moved, some plaster falls. Chimneys may be slightly damaged." The motion was somewhat subdued in Christchurch due to the distance but was still obvious as a significant aftershock. Facebook comments within minutes indicated the large area affected and included the following: "Really felt it here in Oxford! Almost felt like September again just shorter. Threw me out of bed! Woke me up in Kaiapoi but I wasn't quite sure if we were having one. Everyone else still asleep. Too tired after staying up late last night to watch the wedding. Felt that in Redwood, so much for a sleep in. Felt that in Belfast - also heard from dad in Rakaia who said his house shook really badly. Felt it in Ashburton. Woke me up with a sudden jolt."

Christchurch experienced five aftershocks in the 24 hours preceding the 5.2 shake. These ranged from a 2.8 to a 3.8.

US: 4.3 earthquake measured 84 miles southeast of El Paso

A 4.3 earthquake shook part of West Texas and Northern Chihuahua late Wednesday, according to the U.S. Geological Survey.

The temblor was centered in the state of Chihuahua about 40 miles south of Fort Hancock, Texas, said Aaron Velasco, a seismologist and chairman of the Geology Department at the University of Texas at El Paso.

UTEP has a seismograph that records seismic activity.

Velasco said the earthquake occurred in an area that includes a valley used for agriculture and some mountains.

The earthquake began just before 11 p.m. on Wednesday and emanated from about 6.2 miles deep in the earth. The region of the epicenter is about 84 miles southeast of El Paso.

Velasco said the shaking took place in a region that does not appear to have a history of significant earthquake activity.

"There was a whole sequence of events," he said. "There was a 4.3 and a 4.1 earthquake and six to seven smaller ones. We're going to study this further."
