Volunteers picked up debris in and around the pond
SPRINGFIELD, Mass. (WWLP) – It’s been nearly two years since the June 1 tornado barreled through the City of Springfield, but there are still debris left in Water Shops Pond.
So on Saturday, Springfield city workers and volunteers picked up debris in and around the pond.
Volunteers used Police and Fire rescue boats to pull out trash barrels, branches and other debris left behind after the June 1 tornado.
Springfield City Councilor Tim Allen told 22News even though land around the pond has been cleaned up by neighbors, debris in the pond continue to remind residents of what happened back in 2011.
Springfield Mayor Domenic Sarno said this clean up is taking the city one step closer to full recovery.
A 6.4 earthquake hit Papua New Guinea Tuesday, piggy-backing off the 6.6 quake that rocked the country just last week. The 6.4 earthquake occurred about 20 miles north of Rabaul, a township located on the eastern-most tip of the Papua New Guinea island cluster.
So far, there have been no reports of any major damage in the country, the Christian Science Monitor reports. Luckily, the 6.4 earthquake did not create a tsunami, a possibility that had residents of Hawaii on edge.
Two simultaneous big quakes near Papua New Guinea in just over a week? What’s the reason for New Guinea’s frequent seismic activity?
Measuring An Earthquake
The magnitude of an earthquake, like the 6.4 earthquake that hit Papua New Guinea Tuesday, is measured on the Richter scale. Developed in 1934 by Charles Richter, the scale goes from 1 to 10, Earthquakes are assigned a number between 1 and 10, with an exponential numerical increase correlating to a ten-fold increase in seismic activity, according to the Michigan Technological University, or MTU. For instance, a 5.0 quake has seismic waves ten times as wide as a 4.0 quake, with an exponentially greater increase in energy released. Pa
According to the Richter scale, a magnitude 2 earthquake is small enough that usually only instruments detect any ground movement. A magnitude 3 quake is felt indoors; an earthquake measuring 5 on the Richter scale is felt by everyone and causes minor to moderate damage; a 6 might see moderate to major damage.
MTU reports that there are an estimated 100 magnitude 6 quakes every year, in addition to approximately 900,000 quakes of magnitude 2.5 or less. That’s about 2,400 small earthquakes every day.
Catastrophic magnitude 8.0 earthquakes, equivalent to detonating 6 million tons of TNT, happen once every five to 10 years. The largest earthquake ever recorded, a magnitude 9.5, occurred in Chile in 1960. According to Encyclopedia Britannica, the quake was so large that tsunami waves 35 feet high reached Hawaii 6,200 miles away, causing millions of dollars in damage at Hilo Bay.
Papua New Guinea: Prime Earthquake Territory
Papua New Guinea, an island nation of roughly 6 million people, lies on a plate boundary known as the Pacific Ring of Fire. It’s the most seismically active region in the world, with about 90 percent of the world’s earthquakes occurring along this ring.
According to the U.S. Geological Survey, since 1900, the New Guinea region has experienced 22 magnitude 7.5+ earthquakes. From the U.S. Geological Survey:
The western end of the Australia-Pacific plate boundary is perhaps the most complex portion of this boundary, extending 2000 km from Indonesia and the Banda Sea to eastern New Guinea. The boundary is dominantly convergent along an arc-continent collision segment spanning the width of New Guinea, but the regions near the edges of the impinging Australia continental margin also include relatively short segments of extensional, strike-slip and convergent deformation. The dominant convergence is accommodated by shortening and uplift across a 250-350 km-wide band of northern New Guinea, as well as by slow southward-verging subduction of the Pacific plate north of New Guinea at the New Guinea trench.
LOS ANGELES (LALATE) – A Southern California earthquake today 2013 has struck Los Angeles. The Southern California earthquake today April 26, 2013 began moments ago. It struck Marina Del Rey, Venice, Santa Monica, and thePacific Palisades. Mapping released to news tonight reveals that the quake erupted south of Marina Del Rey, between Playa del Rey and Westchester, just east of Dockweiler Beach, and north of Manhattan Beach. No reports of injuries have yet to be indicated by local news.
Officials tell news that a moderate but shallow Southern California earthquakestruck tonight. A 3.2 magnitude quake erupted in the region at 7:52 PM PST. The quake however posted a nominal depth. USGS indicates to news that the quake started only eight miles below ground level. As a result the quake could be felt across the region.
Unlike recent Marina Del Rey, West Los Angeles earthquakes, this one was notcentered out to sea in the Pacific Ocean. It was centered on land. As a result, the quake’s impact was felt across the beach communities.
USGS indicates to news that quake started two miles southeast of Marina Del Rey. The quake was three miles northwest of El Segundo and four miles southwest of Culver City. Officials also tell news that quake was four miles west of Inglewood and twelve miles west of downtown.
