What Was That Rumble? Officials Confirm 4.2 Magnitude Earthquake Hits Michigan
May 2, 2015 12:42 PM
KALAMAZOO (WWJ) – If you thought you felt an earthquake on Saturday — you did. And It was one of the strongest quakes ever experienced in Michigan. Officials with the United States Geological Survey said an earthquake with a magnitude of 4.2 and a depth of focus of 5.9 km was measured around 12:23 p.m. about nine miles southeast of Kalamazoo. Multiple residents in several different regions beyond Kalamazoo — from Mount Pleasant and Sterling Heights to Lansing and even as far as Cleveland, Ohio — reported feeling a rumble and the ground shake for between five and 10 seconds. No damage or injuries have been reported. The strongest earthquake in Michigan history was a 4.6 magnitude in nearly the exact same location in August 1947.
In 2010 a large earth crack appeared in Upper Michigan.
One day the land was flat and filled with trees shooting straight into the air. Twenty-four hours later there’s a 600-foot-long crack, 4-feet deep twisting its way through the woods – and those vertical trees are now pointed 30 degrees left and right where the earth has mounded 15 feet high. No, it’s not a disaster movie; it’s what happened Monday at the home of Eileen Heider on Bay de Noc Road in Birch Creek. Heider was sitting in her recliner watching TV at about 8:30 that morning. “The chair shook for a few seconds and I thought the spring in the chair went,” she said. … The next day Heider’s friend, Doug Salewski, found a hole in the ground and a 200-yard crevasse a short ways away which wasn’t there before. Heider went to investigate and said the crack was three-feet wide and about five-feet deep in spots.

LONDON: An earth tremor of magnitude 5.7 struck 185km south-southeast of Japan’s Izu islands on Saturday (May 2), the United States Geological Survey said. The USGS at first put the quake at 6.1, but later revised it to a weaker reading. The tremor was at a shallow depth of 10km.
Underwater Volcano May Be Erupting Off Oregon
An underwater volcano off the coast of Oregon has risen from its slumber and may be spewing out lava about a mile beneath the sea. Researchers were alerted to the possible submarine eruption of the Axial Seamount, located about 300 miles (480 kilometers) off the West Coast, by large changes in the seafloor elevation and an increase in the number of tiny earthquakes on April 24. Geologists Bill Chadwick, of the Pacific Marine Environmental Laboratory and Oregon State University, and Scott Nooner, of the University of North Carolina, Wilmington, successfully forecast the eruption in a blog post in September 2014.
Nepal Earthquake Shrank Mount Everest, Lifted Areas Near Kathmandu 3 Feet
Nepal’s massive 7.8-magnitude earthquake transformed the land the was shaken by the natural disaster, pushing areas near the city of Kathmandu higher in elevation and making Mount Everest slightly shorter. It won’t be enough to unseat Everest as the world’s tallest peak, but according to studies performed after last weekend’s temblor, the mountain is now an inch shorter than before the quake. On the other hand, some locations just outside Nepal’s capital city of Kathmandu were lifted 3 feet higher than before the tragic event, the study also found.
Lava lake on Hawaii’s volcano overflows in spectacular show
HONOLULU (AP) — A lake of lava on Hawaii’s Kilauea volcano has been rising over the past week and, at times, overflowing in a spectacular show. Video posted online by visitors shows lava splashing over the side of the vent rim. Janet Babb, a geologist with the U.S. Geological Survey Hawaiian Volcano Observatory, said Thursday that this is the first time lava from this vent has come into view from a public platform within Hawaii Volcanoes National Park on Hawaii’s Big Island. “It’s always been out of view for visitors who were in the park public viewing areas,” she said. But this past week, because of lava is rising inside the volcano, the lava lake rose high enough that it was visible, she said. The last time molten lava was visible in the crater was in 1982 when a fissure erupted. The last time there was a lake was in 1974.
Bulusan volcano erupts
Mount Bulusan in the province of Sorsogon erupted on Friday morning, causing an explosion of steam and ash that lasted five minutes followed by 40 volcanic quakes, government seismologists said. While the Philippine Institute of Volcanology and Seismology (Phivolcs) did not raise the alert level at the volcano, it warned the public against venturing into Mount Bulusan’s four-kilometer permanent danger zone because of possibility of sudden explosion. Ed Laguerta, Phivolcs resident volcanologist, told The Manila Times that the explosion scattered ash in Puting Sapa and Sangayon villages of Juban town and in Cogon, Gulang-Gulang and Tinampo villages of Irosin town. “This is just a minor explosion [that] coincided with Labor Day celebrations. We’re closely monitoring the [volcanic] activity if it will escalate in the coming days,” he said.
Around 10:30 a.m., when the crater became visible, dirty-white steam was seen coming out of it. Phivolcs seismologists said Mount Bulusan, one of the most active volcanoes in the country, exploded at 8:09 a.m. The volcano has erupted 15 times since 1885 and is considered as the 4th most active volcano in the Philippines after Mayon, Taal and Kanlaon. Bulusan last erupted in 2011.
