Earthquake science research with a microsatellite

Abstract

Reliable, repeatable earthquake forecast is a subject surrounded by controversy and scepticism. What is clear is that reliable forecast would be a critical tool for effective earthquake disaster management. It is proposed that satellites and ground-based facilities may detect earthquake precursors in the ionosphere a few hours or days before the main shock. A low-cost 100 kg class satellite carrying a topside sounder is proposed, to make systematic measurements over seismically active zones. The mission aims to confirm or refute the hypothesis of ionospheric earthquake precursors, define the reliability and reproducibility, and enable further scientific understanding of their mechanisms.

Unmastered risks: From crisis to catastrophe

“…In most cases they are designed for one or two phases, and very rarely they support the four phases. This is especially true for natural hazards such as hurricanes (Caruson and MacManus, 2006;Chua, 2007;Chua et al, 2007;Gerber, 2007;Weeks, 2007), tsunamis (Scanlon et al, 2007;Tolentino, 2007) global warming (Anderson, 2003), pandemic flu (Fraser et al, 2004;Achampong, 2007), earthquakes (Jason et al, 2003) and volcanism (Wadge, 2003). Thus, while lots of single studies are available, the missing synthesis within a normative framework, inhibits evidence based management and benchmarking.…”

“…Email: abhay_s@rediffmail.com earthquake forecasting is a subject surrounded by controversy and scepticism. Substantial progress has been made on the development of earthquake methods for earthquake-hazard analysis on a time scale of a few decades (Jason et al 2003). However, the forecast of specific earthquakes on time scales of a few years to a few days is a highly complex problem.…”
