Lituya Bay is hit by a mega-tsunami. At 10:15 p.m. an earthquake with a magnitude of 7.9 struck the Lituya Bay area, which is still daylight for Lituya Bay during that time of year.
The tide was ebbing at about plus 1.5m and the weather was clear. Anchored in Anchorage Cove, near the west side of the entrance of the bay, Bill and Vivian Swanson were on their boat fishing when the unthinkable happened, the wave is recorded at 524 meters high, making it the largest wave in history, 470 feet taller than the Empire State Building.
Eyewitness account refer that: With the first jolt, I tumbled out of the bunk and looked toward the head of the bay where all the noise was coming from. The mountains were shaking something awful, with slide of rock and snow, but what I noticed mostly was the glacier, the north glacier, the one they call Lituya Glacier. Read More…
A landslide dam on the Dadu River created by Kangding Loudingan earthquake collapses and the resulting flood extended 1400 km downstream, and killed 100,000 people. It is the second-deadliest landslide disaster on record.
A 6.4 moment magnitude earthquake has hit Andaman Islands on Tuesday at 1:21:48 AM local time (Monday 19:51:48 UTC), USGS has reported.
The earthquake had a depth of 127.7 kilometers (79.4 miles). The epicenter was located 120 kilometers at the southeast of Port Blair, Andaman Islands; 350 kilometers at the north of Mohean, Nicobar Islands; 795 kilometers at the southwest of Bangkok, Thailand and 2580 kilometers at the southeast of New Delhi, India.
No casualties or damage has been reported, and no tsunami alert was issued.
A 6.5 magnitude earthquake occurred in Acre, a Brazilian state, at 16:18:29 UTC (11:18 local time), United States Geological Survey (USGS) reported. It had a depth of 565.3 kilometers.
The epicenter was located 125 kilometers east-southeast of Cruzeiro do Sul, Brazil, 330 kilometers east of Pucallpa, Peru, 460 kilometers south-southwest of Tabatinga, Brazil, and 2700 kilometers west-northwest of Brasilia, Brazil.
A civil defence service spokesman in Cruziero do Sul reported to Times Live that the quake was unnoticed. “This zone suffers a lot of earthquakes, but the last one we really felt was 20 days ago. We didn’t register any disorder or damage on the surface,” he said.
“Generally speaking, quakes more than 500 kilometres deep don’t leave signals in the surface, they are only detected by instruments,” said an official of Brazil’s Seismological Observatory to AFP.
The epicenter was 80 kilometres (50 mi) west-northwest of Chengdu, the capital of Sichuan, with a depth of 19 kilometres (12 mi).
The earthquake was also felt in nearby countries and as far away as both Beijing and Shanghai — 1,500 kilometres (932 mi) and 1,700 kilometres (1,056 mi) away — where office buildings swayed with the tremor.
Approximately 15 million people lived in the affected area. It was the deadliest earthquake to hit China since the 1976 Tangshan earthquake, which killed at least 240,000 people, and the strongest since the 1950 Chayu earthquake in the country, which registered at 8.5 on Richter magnitude scale. It is the 19th deadliest earthquake of all time.
Strong aftershocks, some exceeding magnitude 6, continue to hit the area even months after the main quake, causing new casualties and damage.
The epicentre was 215 kilometres (130 miles) south-southeast of Banda Aceh, Sumatra, and 630 kilometres (390 miles) west of Malaysia’s capital Kuala Lumpur, at a depth of 45 kilometres (28 miles), the USGS reports.
The tremors started at about 13.00 local time (05.59 UTC). A local tsunami alert was made by the Pacific Tsunami Warning Center, but rescinded about an hour and a half later. Read More…
On late Monday, the United States Geological Survey (USGS) has reported another earthquake at 19:09:43 local time (23:09:43 UTC).
The epicenter was located 110 kilometers northwest of Temuco; 132 kilometers southwest of Concepción; 203 kilometers north of Valdivia and 558 kilometers southwest of Santiago.
The USGS later determined that the earthquake had a depth of 20.6 kilometers, and the epicenter was located 55 kilometers to the south of Lebu.
The University of Chile Geological Survey reported that the earthquake took place 71 kilometers at the west of Tirúa in the Bío Bío Region and had a depth of 22.9 kilometers.
Wikinews’ Diego Grez reported that the earthquake was clearly felt in Pichilemu, almost 300 kilometers to the north of the epicenter. ONEMI reported no casualties.
Another strong aftershock hit Chile early Sunday morning. The aftershock reached a magnitude of 5.9 with the epicenter located 19 kilometers west of Pichilemu, according to the University of Chile Geological Survey (UCGS).
The UCGS has also reported that the quake reached a depth of 30.1 kilometers and that the intensities in the Mercalli scale were: Pichilemu, Navidad and Talca: VI; Rancagua, Santa Cruz, Lolol and San Fernando: V; Casablanca, San Antonio and Santo Domingo: IV; La Calera, La Ligua, Limache, Los Andes, Papudo, Petorca, Quillota, Santiago de Chile, Valparaíso and Viña del Mar: III.
However, the United States Geological Survey (USGS) reported that it reached a magnitude of 5.8; had a depth of 8,5 kilometers; and that the epicenter was located 65 kilometers at the southwest of San Antonio, Valparaíso; 100 kilometers at the west of Rancagua, O’Higgins 105 kilometers at the northwest of Curicó, Maule and; 135 kilometers at the southwest of Santiago, Metropolitan Region.
ONEMI (National Emergencies Office), reported that Talca, located 258 kilometers south of Santiago, was the city where the aftershock was felt the strongest. Pablo Marín of ONEMI told TV Chile no casualties were reported and only some telephone lines had collapsed.
