Earthquake Alert: Warning before shaking using smartphones
Abstract: Today, 100 people get an alert before earthquakes in California. Recent legislation says everyone should get a warning. In the future, your phone will detect earthquakes. In the era of big data and the Internet of Things, how can seismology harness new technologies both for the purpose of science, and to reduce the impact of future disasters around the world? In this seminar, we will discuss the current status of real-time earthquake information using existing seismic and emerging geodetic networks. We will also explore on what might be possible in the near future as the quality and number of sensors in consumer electronics increase by orders of magnitude.
About the Speaker: Richard Allen is the Director of the Berkeley Seismological Laboratory, a Professor and Chair of the Dept. of Earth and Planetary Science at UC Berkeley. He is an expert in earthquake alerting systems, developing methodologies to detect earthquakes and issue warnings prior to shaking. His group uses seismic and GPS sensing networks, and is experimenting with the use of smartphones. Testing of a warning system for the US west coast is currently under way. Allen’s group also uses geophysical sensing networks to image the internal 3D structure of the Earth and constrain the driving forces responsible for earthquakes, volcanoes and other deformation of the Earth’s surface. His research has been featured in Science, Nature, Scientific American, the New York Times and dozens of other media outlets around the world. He has a BA from Cambridge University, a PhD from Princeton University, and was a Postdoctoral Fellow at Caltech.

While Prime Minister Abe Shinzo has emerged as the strongest Japanese leader in a decade, the dark underside of his administration has been widespread accusations of heavy-handed intimidation of the press. Especially in the last year, there have been numerous high-profile cases in which major media organizations have appeared to capitulate to such pressure, often engaging in a preemptive self-censorship known in Japan as jishuku, or “self-restraint.” A close examination of some of these cases reveals that the Abe administration has indeed engaged in an aggressive effort to shape press coverage using both the carrot of access, and the stick of political pressure and unbridled nationalist intimidation. However, much of the blame also belongs in the media organizations themselves, which have appeared unable, at least initially, to resist the administration’s pressure tactics. Indeed, the Abe government has appeared adept at exploiting weaknesses in Japan’s major media that include a competitive obsession with scoops, a heavy dependence on government sources seen in the so-called press club system and the lack of a shared sense of professional ethics and identity. The collapse of political opposition parties, and the strengthening of state secrecy laws during the second Abe administration also play roles. Deeper historical trends will also be considered, including weak notions of civil society and a moral centrality of the state that has its roots in the crash nation-building of the Meiji period.
