There have been exciting advancements in searching for ultra high energy cosmic neutrinos in recent years. In addition to important results from IceCube, there have been a series of experiments/observatories based on the Askaryan effect and geomagnetic synchrotron effect for detection that aim at the detection of highest energy cosmic neutrinos. Among them the balloon-borne ANITA project has made its 3rd mission in Antarctica in the 2014-2015 winter. Ongoing ground-based projects include ARA (Askaryan Radio Array)at the South Pole and ARIANNA on Ross Bay Shelf, Antarctica. The Taiwan team has been playing a leading role in ARA since its inception. The antenna stations built by the Taiwan team has been collecting data since their deployment 2.5 years ago. Several more stations, again built by the Taiwan team, are now scheduled to be deployed at the Pole in the coming two years. Last but not least, taking advantage of steep high mountains along Taiwan’s East Coast, we have launched an exciting new observatory by the name 太魯閣, or TAROGE (Taiwan Astroparticle Radiowave Observatory for Geosynchrotron Emission), to look over the Pacific Ocean in search of ultra high energy cosmic rays and earth skimming neutrinos. In this talk we will review these activities as well as their physics potentials and future prospects.
