"The cyclone itself is a disaster, there is a lot of flooding, then there are landslides and then the earthquakes come," Wdowinski said. Follow LiveScience for the latest in science news and discoveries on Twitter @livescience and on Facebook. This shifting of sediment lifts the weight that keeps faults locked. But when a very wet typhoon or hurricane dumps lots of rain, it often causes large landslides in mountainous areas.

"We have lots of unknowns," Fan said.

"We can have seismic sources in the ocean just like earthquakes within the crust," Fan said.

The 1996 Typhoon Herb was followed by M-6.2 in 1998 and M-7.6 in 1999 and the 1969 Typhoon Flossie was followed by a M-6.2 in 1972. Additionally, other seismic events such as earthquakes must be ruled out. “

Even smaller quakes followed the same pattern, with 35 percent of magnitude-5-and-above quakes occurring within the first four years after wet storms — twice the expected number.

"Strong storms generating earthquake-like seismic activity." Researchers from Woods Hole Oceanographic Institution as well as Scripps Institution of Oceanography and the U.S. Geological Survey contributed to this research.

Timing is everything

Content on this website is for information only. SAN FRANCISCO — Typhoons and hurricanes can trigger large earthquakes in tropical regions, a new study suggests. Bottom line: A new study by scientists at University of Miami suggests that earthquakes, including the recent 2010 temblors in Haiti and Taiwan, might be triggered by tropical cyclones (hurricanes and typhoons.).

That was five times what would have been expected from background quake rates, Wdowinski said.

They cause destruction to property and loss of life every year. All lightning on Earth may have its roots in space, new research suggests. Counting Steps: Are You Walking More, But Enjoying It Less? Strong storms generating earthquake-like seismic activity.

When the hurricane arrived, numerous seismic events were located off the New England and Nova Scotia coasts, which produced transcontinental surface waves.

A Florida State University researcher has uncovered a new geophysical phenomenon where a hurricane or other strong storm can spark seismic events in the nearby ocean as strong as a 3.5 magnitude earthquake. Wdowinski reported his findings here Thursday at the annual meeting of the American Geophysical Union (AGU). "This involves coupling of the atmosphere-ocean and solid earth. It is not intended to provide medical or other professional advice. The twin magnitude 6.4 and 7.1 earthquakes that struck the Ridgecrest area in California’s Mojave Desert northeast of Los Angeles on July 4 and 5, respectively, were felt by up to 30 million people in California, Nevada, Arizona and Baja California, resulting in loss of life, injuries, billions in damage and lots of frazzled nerves.

Wdowinski shows that earthquakes, including the recent 2010 temblors in Haiti and Taiwan, may be triggered by tropical cyclones and the wet rains that accompany them. Questions? Fan and his colleagues developed a novel approach to detect and locate seismic events and determine whether the seismic event is a stormquake. Fan and his colleagues analyzed nearly a decade of seismic and oceanographic records from September 2006 to February 2019 and found a connection between strong storms and intense seismic activity near the edge of continental shelves or ocean banks. Original written by Kathleen Haughney. Earth, Space, Human World, Tonight. It really highlights the richness of the seismic wave field and suggests we are reaching a new level of understanding of seismic waves.". © 2012 OurAmazingPlanet. This figure ma… The researchers decided to see if the timing was a coincidence or whether it meant something more. These quakes are likely not any larger or smaller than they otherwise would have been, Wdowinski said, but the presence of very wet storms may give a hint that a quake-prone region is at higher risk of rupturing in the following years.

"We weren't even aware of the existence of the natural phenomenon. Florida State University. Wdowinski also shows a trend in the tropical cyclone-earthquake pattern exists in M-5 and above earthquakes.

We love your photos and welcome your news tips. Shimon Wdowinski, associate research professor of marine geology and geophysics at University of Miami’s Rosenstiel School of Marine and Atmospheric Science led the study.

The heavy rain induces thousands of landslides and severe erosion, which removes ground material from the Earth’s surface, releasing the stress load and encouraging movement along faults.

Florida State University. "The exciting part is seismic sources caused by hurricanes can last from hours to days."

Wdowinski will discuss his findings during a presentation at the 2011 AGU Fall Meeting in San Francisco. ScienceDaily.

It was a Category 1 hurricane when it approached offshore New England on Aug. 22, 2009. He is spearheading research supported by NASA examining whether powerful hurricanes can trigger earthquakes.

According to the scientists, this earthquake-triggering mechanism is only viable on inclined faults, where the rupture by these faults has a significant vertical movement.

These strained faults are destined to rupture and eventually cause quakes, Wdowinski said. "We can have seismic sources in the ocean just like earthquakes within the crust," Fan said. In the case of the Haiti quake, the 2008 hurricane season had been brutal, with named storms (hurricanes and tropical storms) Fay, Gustav, Hanna and Ike tearing into the island. In the case of Taiwan, 2008's Typhoon Morakot had dumped 115 inches (292 centimeters) of rain in just five days.

Wdowinski and his colleague Igor Tsukanov of Florida International University became interested in whether tropical cyclones interact with earthquakes after noticing that both the 2010 Taiwan earthquake and the 2010 Haiti quake were preceded relatively closely by big storms. The result is that faults already under pressure seem more likely to break in the years after very wet tropical cyclones. "We're calling them 'stormquakes,'" said lead author Wenyuan Fan, an assistant professor of Earth, Ocean and Atmospheric Science. Earthquakes, including the recent 2010 temblors in Haiti and Taiwan, might be triggered by tropical cyclones (hurricanes and typhoons) according to a new study. The researchers plan to analyze patterns in other seismically active mountainous regions – such as the Philippines and Japan – that are subjected to tropical cyclones activity. Smart News Keeping you current Hurricanes May Cause Earthquakes In August 2011, the Virginia earthquake shook the east coast.

The 2009 Morakot typhoon was followed by a M-6.2 in 2009 and M-6.4 in 2010.

The researchers suggest that rain-induced landslides and excess rain carries eroded material downstream.
