Japan: New Earthquake Brings Tsunami Warning

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.

Volcanic quakes recorded at Taal, Bulusan; crater glow at Mayon

Restive Taal Volcano continued to show signs of activity, as state volcanologists recorded at least five volcanic quakes there in the last 24 hours.

The Philippine Institute of Volcanology and Seismology (Phivolcs) on Wednesday said it also observed weak steaming activity at the thermal area of the main crater-lake.

Phivolcs also reiterated its warning against carbon dioxide in the area, saying gas measurements in March amounted to 4,670 tons per day - double the 2,250 tons per day in January.

"The remarkable increase in C02 [Carbon dioxide] concentration indicates anomalous gas release from the magma at depth," it said.

It added Alert Level 1 remains over Taal Volcano, saying no eruption is imminent but the public should strictly observe some safety precautions.

Phivolcs said the main crater should remain strictly off-limits because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate.

Jakarta -- A powerful earthquake struck off the Indonesian island of Java on early Monday morning, seismologists said, prompting a tsunami warning for some local regions.

The 7.1-magnitude earthquake at 3.06 a.m. local time (2006 GMT Sunday) was centered about 279 kilometers (173 miles) south-southwest of Tasikmalaya on Java. It struck about 10 kilometers (6.2 miles) deep, making it a shallow earthquake, according to Indonesia's seismological agency.

Authorities in Indonesia immediately issued a tsunami warning for some coastal areas, while the Pacific Tsunami Warning Center said there was no threat of a Pacific-wide tsunami.

6.4 magnitude earthquake near Crete
A strong earthquake struck the southern Greek island of Crete on Friday, rattling buildings as far away as Cairo, Egypt, across the Mediterranean. Local police said they had no immediate reports of damage or injuries.

The Athens Geological Institute and the German Research Centre for Geosciences in Potsdam, Germany, gave preliminary magnitudes of 6.2, while the U.S. Geological Survey gave the preliminary magnitude as 5.9. Preliminary magnitudes recorded by geological institutes often differ.

The quake struck off the southern coast of Crete at 4:29 p.m. (1329 GMT, 8:29 EDT), 122 kilometres (75 miles) east of the city of Irakleion, at a depth of 77 kilometres (48 miles), the USGS said.

Greece is one of the world's most earthquake-prone countries, but serious damage and fatalities are rare.
