Earthquake Early Warning Starts Nationwide in Japan
When an earthquake occurs, a certain amount of time elapses before destructive seismic energy hits nearby population centers. Though this time is measured on the order of seconds, depending on theExpand

The Status of Earthquake Early Warning around the World: An Introductory Overview
The term "earthquake early warning" (EEW) is used to describe real-time earthquake information systems that have the potential to provide warning prior to significant ground shaking. This is possibleExpand

Preseismic groundwater level changes induced by crustal deformations related to earthquake swarms off the east coast of Izu Peninsula, Japan
[1] Groundwater level changes since October 1994 of Omuroyama-kita (OMR) well in Izu Peninsula, Japan, were examined in relation to six earthquake swarms with which large crustal deformations wereExpand

Magma chamber recharging and tectonic influence on reservoirs: The 1986 eruption of Izu-Oshima
Abstract Although analytical expressions for deformation due to simple reservoirs and planar dikes have been in use for decades, seldom are there sufficient data to provide well-constrained detailedExpand

Preseismic changes in groundwater level and volumetric strain associated with earthquake swarms off the east coast of the Izu Peninsula, Japan
We have observed the groundwater level at Omuroyama-kita (OMR) well on the Izu Peninsula, Japan since October 1994. During the observation period, there were four earthquake swarms. We detected oneExpand
