There was some early-morning shaking happening south of the Coachella Valley Friday. Four earthquakes hit just minutes apart from one another. The first one was a magnitude 3.2, according to the U.S. Geological Survey. It happened at 4:47 a.m. Then, one minute later, three 3.0 magnitude shakers, all hit within seconds of each other at 4:48 a.m. There are no immediate reports of injuries or damages.

Here's how the U.S.G.S. breaks down the science of the earthquakes:

4:47:25 a.m. - a 3.2-magnitude earthquake hit 14 miles from Anza

4:48:42 a.m. - a 3.0-magnitude earthquake hit 15 miles from Borrego Springs

4:48:52 a.m. - another 3.0-magnitude earthquake hit 16 miles from Borrego Springs

4:48:56 a.m. - the final 3.0-magnitude earthquake hit 14 miles from Anza

Africa: Earthquake Magnitude 4.8 rattles rural Tanzania, felt in Kenya; earthquakes rare in Africa

The U.S. Geological Survey says a 4.8-magnitude earthquake shook rural Tanzania southwest of Mount Kilimanjaro.

Friday's earthquake could be felt as far away as Nairobi, Kenya, by people on high floors of downtown buildings. Nairobi is 220 miles (350 kilometers) northeast of the epicenter.

The U.S. Geological Survey says the epicenter was 90 miles (145 kilometers) southwest of Arusha, Tanzania.

Africa does not have any known major earthquake zones. The area southwest of Mount Kilimanjaro is one of the few regions on the continent with regular seismic activity.

If there was ever a sound of devastation this must surely be it.

Scientists have released the menacing noise of the Japan earthquake which plunged the nation into unprecedented chaos when it shook the nation on March 11.

The cataclysmic mega-quake sent a merciless tsunami bulldozing its way through streets and homes wiping out towns and communities in a matter of minutes.

A swarm of earthquakes continued along the California-Nevada border, according to the U.S. Geological Survey.

It began Sunday and continued into Thursday, with scores of small temblors reported.

On Wednesday, the region around Hawthorne, Nev., recorded a 4.4 and 4.1 quake as well as many smaller temblors. There have also been smaller quakes on the California side of the border, along the Eastern Sierras in Inyo and Mono counties.

Taal Volcano quakes increase in number in 24 hours

According to the most recent bulletin of the Philippine Institute of Volcanology and Seismology (Phivolcs), there were 11 earthquakes produced by the activity of the Taal Volcano today, April 12, 2011. This is 4 quakes more than yesterday's recorded volcanic quakes.

The bulletin added that the carbon dioxide emissions of the Volcano is still in high levels which suggest anomalous gas release from the magma at depth. The Alert Level II hoisted last Saturday has not been lifted due to the increased activity of Taal Volcano.

The Institute had advised the public that the Main Crater, Daang Kastila Trail and Mt. Tabaro (1965 -1977 Eruption Site) are strictly off-limits because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate.

In today's episode of TV Patrol, it was reported that there were cracks noted on the walls and floors of the houses and on the roads in Talisay, Batangas which is 10 km away from Taal Volcano. The Phivolcs is still to investigate what caused the cracks.

Survivors in Miyako, Japan, observe a moment of silence in the rubble exactly a month after a massive earthquake and tsunami.

A strong earthquake rattled Japan's northeast Monday and sparked a fresh tsunami alert on the one-month anniversary of the massive temblor and wave that devastated the northeastern coast and unleashed a still-unfolding nuclear crisis.

The 7.1-magnitude aftershock briefly forced Tokyo's main international airport to close both of its runways. The epicenter was just inland and about 100 miles north of Tokyo. The operator of the crippled Fukushima Daiichi nuclear complex said the latest quake had no impact on the plant.

A warning was issued for a three-foot tsunami, the same as for after an aftershock that shook the northeast coast last week. That quake generated no tsunami.

People at a large electronics store in the northeastern city of Sendai screamed and ran outside, though the shaking made it hard to move around. Mothers grabbed their children, and windows shook. After a minute or two, people returned to the store.

A moderate 5.2-magnitude earthquake jolted the Philippines early Saturday, seismologists said, but there were no immediate reports of damage or tsunami warnings issued.

The earthquake struck at 2:29 am (18:29 GMT) around 105 kilometres (65 miles) southwest of Olongapo on the Philippines' Luzon island and 125 kms southwest of the capital Manila, the US Geological Survey said.

It hit at a relatively shallow depth of 24 kms (15 miles), the USGS said.

People in the Philippines have been nervous about a potential killer quake following the devastating ones to have hit Japan and New Zealand recently.

Japan: New Earthquake Brings Tsunami Warning

Thu, 07 Apr 2011 10:59 UTC

A powerful earthquake off the northeast coast of Japan shook a large area late Thursday. The jolt appeared to be an aftershock from the catastrophic earthquake and tsunami that hit Japan nearly four weeks ago.

The earthquake generated a tsunami warning, and Japan's NHK television immediately warned residents in the area to move to higher ground, but there were no immediate reports of major disruptions in the ocean.

The earthquake and tsunami alert raised fears about possible effects at the damaged Fukushima nuclear reactor, which has been leaking radio since the original earthquake.

The Tokyo Electric Power Company said it had no reports of any new damage or casualties near the reactor site caused by Thursday's earthquake, which hit shortly before midnight (at 1432 UTC). The aftershock was initially recorded at magnitude 7.4, but the U.S. Geological Survey later downgraded the jolt to magnitude 7.1 - still a powerful earthquake overall, but far less dangerous than the 9.0-magnitude shock on March 11.

Speaking at a news conference, a TEPCO official said water-pumping operations were continuing to keep the nuclear plant's fuel rods from overheating to a dangerous degree. Workers at the plant have been struggling to bring the nuclear reactors under control for the past three weeks.
