Typhoon Mirinae (Santi) is likely to pass across Luzon in the next 24 hours
The latest track forecasts for Typhoon Mirinae (Santi) suggest that a direct hit on Luzon is now highly likely:Mirinae is not especially strong in terms of windspeed, but the eTRaP data suggest that rainfall volumes are high (this is the precipitation forecast for the next 24 hours): The topography of this area is pretty mountainous, and the typhoon will pass close to Manila: The ground is likely to still be …

Typhoon Mirinae (Santi)
Click here for the latest update Once again Luzon in the Philippines is staring down the barrel of a powerful tropical cyclone, Typhoon Mirinae (known locally as Typhoon Santi). The storm is currently forecast to track across the southern part of Luzon on Friday evening:The 24 hour eTRaP precipitation forecast for the storm suggests that it is, as expected, inducing substantial amounts of precipitation along track: At the moment the …

Animation of Seattle harbour liquefaction failures
Youtube has a rather cool video of an animation of the effects of a large earthquake on the harbour side area of Seattle. The main point is I think to show the effects of the earthquake on the elevated roadway, but it also shows liquefaction failures of the fill behind the sea wall: Pretty neat – certainly a useful teaching tool.

Just when you thought it was safe to go out in Luzon…
…another potential typhoon appears (Tropical Storm 23): Unbelievable, although the track error this far out is of course very high.

New atlas of natural disaster threats in the Andes
On Friday the Andean Community of Nations (CAN) (Bolivia, Colombia, Ecuador and Peru) released an atlas of potential natural disasters affecting the countries of that region, which has come out of the PREDECAN project. It presents maps of the distributions of earthquakes, volcanic eruptions, landslides, flooding, frost and drought, with a special emphasis on El Nino / La Nina. As far as I can tell this atlas is available only …

Typhoon Lupit stalls off the coast of Luzon
Typhoon Lupit (Ramil) has now stalled off the northern coast off Luzon and is forecast to recurve and to head northwards, whilst weakening as it encounters increasingly cold water over the next few days: This has been an extremely fortunate outcome, and one that has also exposed the continuing problems with forecasting typhoon tracks. The eTRap forecast for the precipitation over the next 24 hours clearly highlights just how close …

Typhoon Lupit (Ramil) continues to confound!
The behaviour of Typhoon Lupit (Ramil) is becoming increasingly difficult to forecast, primarily because its movement remains quite slow. The latest JTWC track forecast is still suggesting that the track will pass across the northern part of Luzon:However, the storm is now moving slowly and is likely to continue to do so, which makes forecasting its track much more difficult. The major concern is that the JTWC forecast above suggests …

Updates on the Nile River (Naches) landslide
Clearly the Nile River (Naches) landslide has effectively dropped off the media radar now. However, there are some excellent ongoing posts on this slide on the Sliding Though blog, which the is the Washington State landslide blogsite.

Typhoon Lupit (Typhoon Ramil) continues to threaten Luzon
Latest update here Typhoon Lupit (Ramil) has now resumed its westward progress and remains on track to cross the northern part of Luzon in the Philippines:The typhoon has weakened somewhat over the last few hours, with maximum sustained wind speeds now in the order of 85 knots. This weakening appears to be associated with some drier air that surrounded the typhoon, disrupting its organised circulation. However, there is now some …
New York Times article on landslides
There is quite a nice article on recent attempts to monitor and provide warning against landslides in yesterday’s New York Times: http://www.nytimes.com/2009/10/20/science/20mud.html?pagewanted=1&_r=1 There is a small quote in there from me, but my role is very much as support to the main players in this case.
