Quake Rocks Islands Near New Zealand


By RAY LILLEY, Associated Press Writer 18 minutes ago



A powerful earthquake hit deep under the South Pacific late Tuesday north of New Zealand, and it rocked a wide area of the country, but no damage or injuries were reported.

The Pacific Tsunami Warning Center issued a bulletin saying the magnitude 7.4 quake had not generate a destructive Pacific-wide tsunami but warned it could spawn a small tsunami within 60 miles of its epicenter.

The U.S. Geological Survey said the quake hit at 10:39 p.m. (6:39 a.m. EDT) about 90 miles below the seabed, and was centered about 180 miles south-southwest of Raoul Island in the Kermadec island chain, which is 712 miles northeast of New Zealand's largest city, Auckland.

It came hours before countries around the Pacific rim were to test a tsunami warning system spanning the world's largest ocean.

The powerful quake, which New Zealand seismologists said registered at magnitude 7.5, rocked a wide area of the country — but was unlikely to have caused damage, seismologist Ken Gledhill told The Associated Press.

"It has been felt very widely but is unlikely to have caused any damage in New Zealand," he said, adding that within half an hour more than 500 people had reported the quake's impact.

"It was too deep to have ruptured the sea floor," Gledhill said, adding a tsunami was unlikely "if that depth is correct."

A policeman in the east coast North Island town of Whakatane said he was sitting on a chair talking to the police communications center in the northern city of Auckland when it struck.

"Things started moving and I thought, 'this is a goodie,'" said Sgt. Andrew O'Reilly.

Wellington police inspector Peter Stokes said there were no immediate reports of injury or damage.

"We sure did feel it. Our building swayed a bit," he said.

Raoul Island was the center of a series of earthquakes during a volcanic eruption in March that killed a New Zealand Department of Conservation worker and forced the evacuation of the island.

Several conservation workers returned to the island last month to perform tasks like eradicating weeds, monitoring birds and preventing the arrival of unwanted pests such as rats.

There was no immediate word on whether they were affected by the quake.

The quake was felt as far south as Christchurch on South Island.

New Zealand is among more than two dozen countries taking part in the drill to test the Pacific warning system that has been in place since 1965.

During the exercise early Wednesday, the Pacific Tsunami Warning Center in Hawaii will send out warnings about mock earthquakes off the Chilean coast and Luzon island in the northern Philippines that are powerful enough to set off a tsunami across the vast ocean.

Governments will test if and how fast they receive the warnings and how rapidly they are relayed through domestic emergency alert systems.

This has nothing to do with hurricanes and storms so I will move it to global weather forum.

Strong Undersea Earthquake Strikes Near Indonesia

JAKARTA, Indonesia — A strong undersea earthquake struck off eastern Indonesia late Friday, the U.S. Geological Survey said. There were no immediate reports of injuries, damage or a possible tsunami.

The magnitude 6.2 quake struck at 11:44 p.m. and was centered 34 miles beneath the Molucca Sea, the USGS said on its Web site.

Indonesia, the world's largest archipelago, is prone to seismic upheaval due to its location on the so-called Pacific "Ring of Fire," an arc of volcanos and fault lines encircling the Pacific Basin.

A magnitude 9 earthquake and subsequent tsunami on Dec. 26 killed more than 131,000 people in Indonesia's western Aceh province and left a half-million homeless.

The USGS Web site mentioned no immediate possibility of a tsunami.

Villagers Try to Appease Indonesia's Mt. Merapi

MOUNT MERAPI, Indonesia — Some Indonesian villagers are trying to appease the rumbling Mount Merapi in Indonesia.

An elderly man entrusted with being the volcano's spiritual guardian led a dozen followers in a pre-dawn ceremony intended to calm villagers as the mountain continues spewing lava.

Hundreds of villagers living on Merapi's slopes continue defying orders to leave the danger zone, despite repeated calls for them to go into evacuation centers. They say the centers are like living "in a prison" and they prefer to take their chances with the mountain.

The 9,800-foot volcano has been shooting out lava and deadly clouds of hot ash and debris for several weeks. It has been rocked by a series of spectacular eruptions since Saturday, with the most recent occurring Wednesday.

Mount Merapi, which translates as "Fire Mountain," has erupted scores of time over the last 200 years, often with deadly results. It is one of the world's most active volcanoes.

In 1994, 60 people were killed by a searing gas cloud, while in 1930, more than a dozen villages were incinerated, leaving 1,300 dead.

Earthquake kills more than 3,500 in Indonesia

Thousands more injured in central Java province after 6.2 temblor

MSNBC News Services
Updated: 2 hours, 42 minutes ago
YOGYAKARTA, Indonesia - A powerful earthquake flattened homes and hotels in central Indonesia early Saturday as people slept, killing more than 3,500 and injuring thousands more in the nation’s worst disaster since the 2004 tsunami.

The magnitude-6.2 quake struck at 5:54 a.m. near the ancient city of Yogyakarta, 250 miles east of the capital, Jakarta. It was centered about six miles below the surface, the U.S. Geological Survey said.

The quake’s epicenter was close to the rumbling Mount Merapi volcano, and activity increased soon after the temblor. A large burst spewed hot clouds and sent debris cascading some two miles down its western flank.

Bambang Dwiyanto of the Energy and Mineral Ministry could not say whether the quake caused the volcanic activity but warned that it could trigger a larger eruption.

“It will influence the activities of Mount Merapi, particularly in the lava dome,” said Dwiyanto, head of the ministry’s geological division.

Almost all people had already been evacuated away from the volcano’s danger zone, and there were no reports of injuries as a result of the eruption.

‘Too scared’
As darkness fell in the heartland of Indonesia’s main island of Java, thousands were preparing to spend the night outside their ruined homes or on the grounds of mosques, churches and schools.

“It’s pitch dark. We have to use candles and we are sitting outside now. We are too scared to sleep inside. The radio keeps saying there will be more quakes. We still feel the tremors,” said Tjut Nariman, who lives on the outskirts of Yogyakarta.

TV footage showed damaged hotels and government buildings, and several collapsed buildings. Roads and bridges were destroyed, hindering efforts to get the wounded to hospitals. Some phone lines also were cut.

“It felt really powerful, and the whole building shook,” said Narman, a receptionist at a hotel in Yogyakarta. “Everyone ran from their rooms.”

Rising death toll
President Susilo Bambang Yudhoyono ordered the army to help evacuate victims and arrived in densely populated Central Java province Saturday afternoon with a team of Cabinet ministers to oversee rescue operations. He also told people not to fear a tsunami.

Sixteen hours after the quake struck, the number of dead stood at 3,068, Social Affairs Ministry official Sopar Jaya said, adding that two-thirds of the fatalities occurred in devastated Bantul.


In the chaos that followed the quake, rumors of an impending tsunami sent thousands of people on Java fleeing to higher ground in cars and motorbikes. But Japan’s Meteorological Agency said there was no danger of a killer wave.

Doctors struggled to care for hundreds of injured people lying on plastic sheets, straw mats and even newspapers outside the overcrowded hospitals, some hooked to intravenous drips dangling from trees.

“We need help here,” said Kusmarwanto of Bantul Muhammadiyah Hospital, the closest hospital to the quake’s epicenter, adding that his hospital alone had 39 bodies.

“There so many casualties. Houses ... are flattened. Many people still need to be evacuated,” he said.

At nearby Dr. Sardjito Hospital, bodies were lined up in the hallway and some family members were taking them home before they could be added to the official toll.

“We have hundreds of injured people, our emergency care unit is overwhelmed,” said Heru Nugroho.

The quake cracked the runway in Yogyakarta’s airport, closing it to aircraft until at least Sunday while inspections take place, Transport Minister Hatta Radjasa said.

Officials said Borobudur temple, a 9th century Buddhist structure considered one of the seven wonders of the world, was not affected in the quake.

In hardest hit Bantul district, Subarjo, a 70-year-old food vendor, was sobbing next to his dead wife, his house destroyed.

“I couldn’t help my wife ... I was trying to rescue my children, one with a broken leg, and then the house collapsed. I couldn’t help my wife,” he said weakly.

“I have to accept this as our destiny, as God’s will,” he added.

Volcanic eruption
The quake’s epicenter was close to Mount Merapi, which has been rumbling for weeks and sending out large clouds of hot gas and ash.

Activity increased on Saturday, with one eruption that came soon after the quake sending debris some 2 miles down its western flank, but Bambang Dwiyanto of the Energy and Mineral Ministry said the two events did not appear to be directly related.

Almost all people had already been evacuated away from the volcano’s danger zone, and there were no reports of injuries as a result of the eruption.

Indonesia, the world’s largest archipelago, is prone to seismic upheaval due to its location on the so-called Pacific “Ring of Fire,” an arc of volcanos and fault lines encircling the Pacific Basin.

A magnitude 9.1 earthquake on Dec. 26, 2004, under the sea off the coast of Indonesia’s Sumatra Island triggered a tsunami that killed more than 131,000 people in Aceh province, and more than 100,000 others in nearly a dozen other countries.

Strong quakes rattle islands in South Pacific

No reports of damage or tsunami threat for Tonga, Papua New Guinea

SINGAPORE - A strong quake measuring 6.7 in magnitude rocked the South Pacific island nation of Tonga on Sunday, the U.S. Geological Survey said.

The New Britain region of Papua New Guinea was also shaken by a 6.2 magnitude quake, the USGS reported. It was unclear whether the tremors had caused any casualties or damage.

It said the Tonga quake hit at 4:36 p.m. local time 90 miles northeast of the capital Nuku’alofa. The tremor was registered at a depth of 31 miles.

The Pacific Tsunami Warning Center in Hawaii said the quake near Papua New Guinea’s New Britain island hit at about 0326 GMT Sunday.

“No destructive Pacific-wide tsunami threat exists based on historical earthquake and tsunami data,” the center said on its Web Site, adding the PNG quake was 6.7 in magnitude.

But the U.S. Geological Survey and Geoscience Australia both registered the quake at 6.2.

Sunday’s quakes followed a quake of similar magnitude which hit Indonesia’s main island of Java on Saturday, killing more than 3,000 people.

“We haven’t had any reports of damage,” a Geoscience Australia spokeswoman said.

The earth just passed between Jupiter and Venus. They are the solar systems heavy hitters as far as gravity goes. There was a New Moon 05-27-2006. That would add a little shear to the equation. The number of small quakes around Southern California is usually around 17 to 20 at the New Moon this month it is about 45.

not to be picky but how is seismic activity associatd with weather?

Never heard of "Earthquake Weather"? Actually it's just a myth. Actually, since NOAA runs the Tsunami Warning Center and the USGS and NOAA are often coolocated and Spotters are supposed to report any tremors they feel there's a symbiotic relationship there. Also, the NWS has the EAS which is the best way to get emergnecy earthquake and volcanic information out quickly. BTW, the Earth is NOT between Venus and Jupiter-Venus is on the far side of the Sun right now and aside from Jupiter the Sun is the only other heavy hitter in terms of gravity in the Solar system.

Object Right Ascension Declination (AU)
Sun 4h 14m 24s +21° 13.5' 1.013
Venus 1h 43m 3s +8° 31.1' 1.154 -
Moon 3h 54m 47s +24° 46.7' 59.4 ER -
Jupiter 14h 37m 7s -13° 59.7' 4.477

If you use an ephemeris instead of an almanac you would see that at the time of the earthquake the angle between the Jupiter Earth and Venus is 193° 31’ 00” and that the Moon is almost inline with the Sun.

I usually relate the force of the Sun to the force of the Moon. The Sun’s force would envelope the equation between Venus, Earth, and Jupiter and be set at zero and considered separately, for the force between the sun moon earth equation the force would be added. Gravitons always pull so the system is in tension. Hence a jerk occurred at that instant. The mechanics are simple.

AND since activity 56 was in the area there would also be an associated increase in evaporation and turbulence, which is not uncommon for an event of this size, causing wet weather and during this time of year tropical disturbances.

I have a different defintion of between I guess. At any rate with Venus on the far side of its orbit from us, its gravitational effects would be much less than if it were close to Inferior Conjunction since those effects vary with square of the distance.

Between is between gravity is associative. A non-conjunctional or oppositional alignment cannot be read from an almanac.

http://home.att.net/~gigabite/force-dynes.gif

This link shows the resolution of the law of universal gravitation as defined by Exploring The Universe 3rd ed copyright 1975 relative to the Moon’s gravitation.

There is enough information above to determine the exact amount of vector gravitation needed to for the earthquake, and it is simple math from here to equate the forces involved to form the earthquake because the vectors are nearly 90°. Ergo the force is equal to 3.2 Moon masses are need to form a 6.8 earthquake in 2 percent equivalent Moon mass of tension.

Guessing is all about eliminating variables by equivalence
