At least 164 aftershocks have been recorded in North Cotabato since a magnitude-5.7 quake jolted the area last June 1, the Philippine Institute of Volcanology and Seismology said Tuesday. But Phivolcs also advised residents in North Cotabato to expect more aftershocks in the coming days, radio dzBB's Allan Gatus reported.

 

Of the 164 aftershocks, at least 22 were felt, including a second magnitude-5.7 quake on Monday. The quakes had prompted authorities to declare a state of calamity in Carmen town in North Cotabato, which suffered much damage. For its part, the National Disaster Risk Reduction and Management Council said at least 141 families had been affected by the quakes.

New Explanation for Slow Earthquakes On San Andreas

New Zealand's geologic hazards agency reported this week an ongoing, "silent" earthquake that began in January is still going strong. Though it is releasing the energy equivalent of a 7.0 earthquake, New Zealanders can't feel it because its energy is being released over a long period of time, therefore slow, rather than a few short seconds.

 

These so-called "slow slip events" are common at subduction zone faults -- where an oceanic plate meets a continental plate and dives beneath it. They also occur on continents along strike-slip faults like California's San Andreas, where two plates move horizontally in opposite directions.

 

6.1 magnitude earthquake strikes near Solomon Islands

Solomon Islands June 5

 

SOLOMON ISLANDS - A 6.1-magnitude earthquake has struck off the Solomon Islands, the US Geological Survey says, but no immediate tsunami warning has been issued. The tremor, at a depth of 64 kilometers, hit in the Santa Cruz Islands, some 89 kilometers south of the remote town of Lata, where a tsunami left at least 10 people dead in February.

 

Geoscience Australia gave a higher preliminary measurement of 6.6-magnitude, but said it was unlikely to have caused a local tsunami in the quake-prone region. “That magnitude may change over time as we get more data,” duty seismologist Spiro Spiliopoulos told AFP, adding that they measured the depth at about 60 kilometers.

HAWAII – A moderate earthquake struck in the deep ocean off Hawaii Island this afternoon but did not generate a tsunami, officials said. The quake, with a magnitude of 5.3, struck at about 2:12 p.m. and was centered 34 miles southeast of Pahala and 31 miles south of Kalapana, at a depth of about 25 miles, according to the U.S. Geological Survey. The quake initially was listed as a magnitude 5.2, briefly upgraded to 5.6 before USGS scientists reassessed and downgraded it to a magnitude 5.3.

 

No tsunami was generated but “some areas may have experienced strong shaking,” according to the Pacific Tsunami Warning Center in Ewa Beach. “It was a pretty significant jolt,” said Darryl Oliveira, director of the Hawaii County Civil Defense, who was on his way to the county building for a hearing when the earthquake occurred.

Philippines: earthquakes in Mindanao to last for months, volcanic anomalies reported underground

DAVAO CITY, Philippines — The earthquakes experienced today in Carmen town, North Cotabato and the rest of Mindanao will possibly last for weeks or months. This was according to Jenila de Ocampo, Officer-in-charge of the Davao Seismic Station of the Philippine Institute of Volcanology and Seismology (Phivolcs), in a phone interview.  She added the intensity might either be “felt” or “unfelt” by humans. On Monday morning, two strong quakes struck Carmen.

 

A 5.7 magnitude was felt at 4:08 AM with epicenter at seven Kilometers (Km) Northeast of the town.  It has a depth of 10 Km.  The town was placed under Intensity VI. “An Intensity VI in the PEIS (Phivolcs Earthquake Intensity Scale) means there will be a minimal damage to poorly built structures, or those with light materials and even concrete structures which do not meet building standards like the proper placement of steel bars,” De Ocampo explained. At 7:31 AM, another quake jolted Carmen town.

TAIPEI, Taiwan (AP) — A strong earthquake jolted Taiwan on Sunday, killing two people and injuring at least 21 others and causing panicked shoppers to rush out of a shaking multi-story department store, officials said. Another earthquake jolted the southern Philippines late Saturday, injuring at least 33 people and damaging more than 140 houses.

 

The tremor that hit Taiwan on Sunday afternoon was felt all over the island, but most severely in the central and southern regions. The magnitude-6.3 quake's epicenter was near Jenai township in Nantou County in central Taiwan, about 250 kilometers (155 miles) south of Taipei, the Central Weather Bureau said.
