Silence to sound: Looking at Twitter posts from 2017’s Hurricane Harvey shows lack of activity can tell first responders where trouble’s brewing

With another hurricane season beginning June 1 — and some forecasters predicting another busy one — researchers in the School of Civil and Environmental Engineering are working on a tool to help first-responders use Twitter activity to identify developing crises after a storm while also helping civilians more effectively plug in to disaster response efforts.

Eyewitness accounts fill in details of 1946 Dominican Republic tsunami

Claudio Martinez from the Dominican Republic’s Oficina Nacional de Meteorologia in Matancitas with local resident Patria, right, who took Martinez and Georgia Tech’s Hermann Fritz back to the site of a 1946 tsunami in the area. Patria remembered how high waters had reached at this palm tree, helping the team reconstruct the tsunami’s impacts more than seven decades after it happened. (Photo Courtesy: Hermann Fritz)

Almost 70 years later, the man remembered the August day in Playa Rincon, when he clung to the top of an almond tree to survive a tsunami where the waters rushed about 700 meters inland after a magnitude 8.1 earthquake.

Yavari’s new project will lay a mathematical foundation for cloaking structures

Can you hide a building from a stress wave, like an earthquake or even some kind of blast or explosion? If that kind of “cloaking” were possible, it could shape how we design critical structures like nuclear power plants. Arash Yavari has started a new four-year, half-million dollar federally funded project to lay the mathematical foundations for that kind of technology and explore if it’s theoretically possible while still respecting the laws of physics.

Documenting disaster: Group led by Tech experts gathers key data after major catastrophes to prepare for the next one

Alejandro Martinez collects data in Mexico after a major earthquake in September 2017. Martinez, MSCE 2012, Ph.D. 2015, was part of a team from the Geotechnical Extreme Events Reconnaissance Association that traveled to the impact zone to gather “perishable” data about the earthquake to help scientists and engineers prepare for future events.

Just days after a major earthquake struck central Mexico in September 2017, Alejandro Martinez, MSCE 2012, Ph.D. 2015, found himself at the site taking vital measurements of the disaster. “It was a shocking day for everyone,” Martinez says.

AUDIO: Hurricane Matthew compounds problems for Haiti’s infrastructure

Hermann Fritz, right, talks with people in Haiti on one of his research trips after an earthquake wreaked havoc on the island nation in 2010. Fritz told public radio's Marketplace the temporary communities that have since sprung up on the country's hillsides are now at risk from flooding and landslides in the wake of Hurricane Matthew.

The rain and flooding from Hurricane Matthew threatens to wash away the makeshift communities that have sprouted on Haiti’s hillsides, making life worse for a country still recovering from a devastating earthquake six years ago. Associate Professor Hermann Fritz told the public radio program Marketplace the shacks people live in on those hills are vulnerable to flooding and landslides.

Two weeks in China and Japan teaches students about disaster engineering, Asian culture — and themselves

The International Disaster Reconnaissance Studies class on the Great Wall of China, one of their first stops during their two-week trip to China and Japan.

They climbed the Great Wall of China and explored the Forbidden City. They visited a town destroyed by an earthquake then preserved as a monument to the lives lost. They saw baby pandas and flood control systems, Japanese towns devastated by a tsunami and the Hiroshima memorial. But in the end, it was the relationships they built and an overnight summit of Mt. Fuji in Japan that etched this trip into the memories of four engineering students who traveled to China and Japan in early August.

10 years after Katrina, are American cities prepared for disasters?

Ahead of a Washington D.C. roundtable August 5 on disaster preparedness, Reginald DesRoches and Wayne Clough talked to the Georgia Tech News Center about the challenges for many of the country's communities. The conversation comes just a few weeks before the 10-year anniversary of the hurricane that devastated New Orleans and ravaged the Gulf Coast.
