Hundreds of people near Indonesia's Moluccas islands rushed to higher ground on Wednesday after an earthquake of magnitude 6.1, fearing aftershocks and a possible tsunami.

The quake struck at a depth of 19 km (11 miles). There were no immediate reports of casualties.

Indonesia's Meteorology and Geophysics Agency (BMKG) urged people in a text message to move away from beaches and seek higher ground, noting that the warning applied especially to Seram Island.

BMKG had initially said a tsunami triggered by the movement of tectonic plates was unlikely - but then said one could still be triggered by underwater landslides, of which there would be no warning.

"If the tsunami is caused by an underwater landslide, it cannot be detected from the current early warning system," the head of BMKG, Dwikorita Karnawati,told a news conference.

Two earthquakes hit Saturday near Government Camp, Oregon, one of them topping out at magnitude 3.9.

The tremors were strong enough for some locals to feel it, The Oregonian reported.

The earthquake rumbled at 8:51 p.m. June 5, just south of the summit of Mount Hood. It was preceded by several earthquakes in the hour before the quake, and tens of aftershocks have occurred since, the Cascades Volcano Observatory of the U.S. Geological Survey reported in a news release Saturday night.

The volcanic action and location are consistent with past swarms in the Mount Hood area, including a magnitude 4.5 on June 29, 2002, that was located about 1 mile east of Saturday's ground shaker.

Aftershocks will likely continue for hours or days, some of which may be felt, according to the news release.

A swarm of earthquakes is currently impacting southern California
A significant earthquake swarm is unfolding in southern California, impacting the area around the Salton Sea east of San Diego, south of Palm Springs, and southeast of Los Angeles. 47 earthquakes with a magnitude of 2.5 or greater have struck the area, with the strongest being a 5.3 which struck at 10:55am local time today.

The strong 5.3 earthquake struck about 6 and a half miles west of Calipatria at a depth of 3.6 miles. More than 700 residents from Los Angeles to San Diego to El Centro reported experiencing the quake to the USGS, including many that reported "strong shaking."

Today's significant earthquake swarm is occurring near the Salton Sea, a shallow landlocked lake with a high salt concentration in Riverside and Imperial counties of California. The Salton Sea sits on the San Andreas Fault at the southern end of the state of California. In this region, the Earth's crust is being stretched. Today's earthquakes are tied to submerged faults near the southern end of the San Andreas Fault. Called the Brawley seismic zone, this extensional region connects the San Andreas with the Imperial Fault in southern California.

Today's swarm comes on the heels of another earthquake swarm that impacted the Disney Land area last weekend north of today's swarm.

A 6.1-magnitude earthquake struck off the coast of Indonesia's remote Maluku islands Thursday, the United States Geological Survey said, but no tsunami warning was issued.

The strong quake hit at a relatively shallow depth of 31 kilometres (20 miles), about 127 kilometres southwest of the city of Ternate.

Shallower quakes tend to cause more damage, but there were no immediate reports of casualties.

"It was a decent shake, but people weren't panicking," said Ternate resident Nasarudin Amin.

"There are warnings about potential aftershocks."

Earthquakes in New York? Yes, it does happen occasionally. If you have friends or relatives in Livingston County, then you might want to check to see if they felt the small tremor that occurred Thursday evening. The United State Geological Survey says the small 2.4 magnitude quake struck just north of the town of Tuscarora, NY, just east of Letchworth State Park. WBNG did not indicate whether or not there was any damage in the area.

But while the quake was small, it was also considered shallow (around 12,000 feet below the surface, according to WROC) The Daily News Online says that some residents described the tremor on social media as a "loud boom", while others said their porch floor shook "quickly and vigorously". Livingston County Sheriff Thomas Dougherty said over Twitter that his office received multiple calls from concerned residents.

Back in March, an area just north of the Hudson Valley felt an earthquake, somewhat like this most recent tremor The United States Geological Survey says a small quake occurred near Altamount, NY, in Albany County. News 10 is reporting that the quake measured a 2.0 on the Richter Scale. Yes, earthquakes do happen in the Northeastern U.S. and Canada. 2020 actually started off with three small earthquakes, on January 3, 7, and 13 respectively. The third was the strongest of the trio, measuring a magnitude 3.3, that hit several miles south of the town of Ormstown, Quebec. The Times Union says the quake was felt as far south as the town of Ticonderoga, NY.
