In order to gain more insight into the Japan flood forecast pipeline and its “behind-the-scenes” story, we had an interview with Dr. Yi Liu, a data scientist of the flood team here at One Concern who has been playing an important role in our model development and testing.

Q: Can you briefly introduce yourself and your background?

A: My background is in local and large scale coastal modeling and coastal hazard assessment under a changing climate. I got my Ph.D. in civil engineering at Virginia Tech, where I focused on developing a fast and reliable storm surge forecast model and…

Making disasters less disastrous is One Concern’s core mission, and one specific natural disaster we focus on is flooding. Currently, an effort is well underway at One Concern to deploy a national live compound flood forecast pipeline in Japan, as an expansion of last year’s pilot flood pipeline in Kumamoto City, Japan, a successful proof of concept product. The ability to forecast compound floods in a real-time manner with sufficient lead time is critical for emergency managers to make well-informed decisions about evacuation and resource allocation before a flood event. To that end, our Japan flood pipeline is designed to…

mRNA is a trickster molecule. It is an undercover agent that sneaks into the human body with the mission of sending misleading signals to initiate a war on the immune system. The idea of mRNA vaccine is to synthesize specific mRNA molecules to elicit pathogen-specific immune responses. It is no doubt that the COVID-19 pandemic put such technology into massive adoption. The vaccines are the most anticipated final game to get everything back to normal. But when vaccines against other pathogens (influenza, ebola, zika, etc) were developed, the speed wasn’t even comparable — most vaccines’ development cycles can span over…

Note: A version of this article originally appeared in the DomPrep Journal

March 2021 marked the 10th anniversary of the Great East Japan (Tohoku) Earthquake. On the afternoon of 11 March 2011, a magnitude 9.1 megathrust earthquake struck where the Pacific Plate subducts underneath the Honshu region of Japan. This was a massive event. The earthquake rupture lasted 150–160 seconds, with shaking in many communities felt for five or more minutes. The energy released by the earthquake could power the city of Los Angeles for more than a year. Japan was shifted 8 feet to the east and the earth’s…

To commemorate the 10th Anniversary of the Great East Japan Earthquake, One Concern CEO and Co-Founder Ahmad Wani spoke at the Japan Society of Northern California’s Innovation Salon on lessons learned from the disaster. The below remarks have been lightly edited for conciseness and clarity.

What can we do now to increase resilience in cities around the world, so that when the next big disaster hits, the disruption to society, the economy and people’s lives will be less severe?

It seems like every time there is a disaster, it’s almost as if it’s a surprise, and the world has suffered…

Junichi Sakai, Flood and Seismic Engineering Lead

I was given an opportunity to write this article to mark the 10th anniversary of the Great East Japan Earthquake (2011 Tohoku Earthquake). I saw damage caused by the Great Hanshin earthquake in 1995 through news reports when I was a college student, and this inspired me to become a researcher in earthquake engineering. More than 25 years have passed since then. I spent 18 years as a researcher in earthquake engineering for bridges, and thereafter worked as an engineer developing probabilistic risk models for assessing natural catastrophe risks. During these years, I visited damaged cities and towns for reconnaissance…

A Q&A with Nicole Hu, Co-Founder and Chief Technology Officer at One Concern

One Concern is joining International Women’s Day 2021 in celebrating all women and their achievements. As part of this year’s choose to challenge theme, we are calling out gender bias and inequality. At One Concern, we’re constantly working to uncover our blind spots — to make One Concern a more diverse, equitable, and inclusive place to work. Currently, our team comes from 5 continents and 20 countries.

Nicole Hu, Co-Founder and Chief Technology Officer at One Concern, leads the technology team, comprised of more than 30 percent…

A Q&A with Mohit Rikhy, Machine Learning Data Scientist at One Concern

Modeling the impacts of disasters is a highly complex, data-intensive process. At One Concern, we believe that this process requires constant innovation and application of new and untraditional technologies — the most prominent being machine learning and AI. From helping us resolve missing and incomplete data sets to enhancing the predictive and scalable capabilities of our models, our use of machine learning is essential to realizing our mission of building global resilience.

Mohit Rikhy is our machine learning data scientist, who helps us deploy ML in our models and conducts research on the best ways to apply this technology to…

Back in March 2020, it was unclear as to whether people in the US should wear face masks in public. With little knowledge of infectious diseases, people were left with confusing and contradictory information, particularly when health experts and officials in the US made earlier assertions that mask wearing was not recommended for most people. Against this view, officials in several countries in Asia made face masks mandatory in public places. By the time New York state mandated their mask wearing policy on public transport on April 15, the number of daily new cases in the US exceeded 30,000.

What influences our perception of pandemic risk?


Today, we launch the COVID Calculator, a free tool to help organizations take a safety-first approach to adapt to the new normal, and get back to business.

We founded One Concern with a singular vision: to build something that would make the world a more resilient place.

2020 has proven this vision to be more critical now than ever before.

But this year has not only demonstrated the need for resilience — it has fundamentally changed the world’s understanding of the concept altogether. True resilience requires systems that embrace the delicate interconnectedness between people, places, and the processes within them.

Today, we’re launching COVID Calculator, a free tool to help organizations use probabilistic risk modeling to better understand the impact of COVID-19. This launch comes after months…
