And on Thursday I am presenting some thoughts on the need for multihazard databases, and how we might go about designing these.

"A relational disaster database to document and resolve multihazard interactions"

Please come along to these presentations to learn more and get in touch if you’d like to have a chat with me or any of the group – we’re always open to building new collaborations.

If you’re interested in applying for postdocs, fellowships, PhDs in Cambridge I am happy to talk this through as well.

Lorenzo is presenting an update on a new and much-improved software (python, open source) package for monitoring landslide movement from optical data.

Also worrying news for penguins as a second stronghold of theirs, the Falkland Islands, is hit with a 41% tariff (??)

Bad news for Heard Island as the US imposes a 10% tariff on its main export - windborne glaciovolcanic tephra. This is viewed as a boost for local Alaskan and Cascadia sources.

Particularly serious implications for very fine grain sizes as the crypto(tephra) market is volatile at the best of times.

The fault terminates quite abruptly at the northern end (very close to the Irrawaddy) but gradually to the South. The southern termination is quite a bit further than some estimates I have seen, likely somewhere just west of Penwegon.

The surface rupture passes within only a few hundred metres of the two main international airports in the region (Mandalay and Nyapyidaw), in each case with around 5 m of total slip.

Max Van Wyk de Vries @maxvwdv.bsky.social · Apr 2

The maps show horizontal displacements in metres in the EW and NS directions. The fault ruptured by several metres over a distance of almost 500km with total slip was highest close to the largest city in the region, Mandalay.

Very sad to see the damage from the earthquake in Myanmar. My thoughts are with all affected by this disaster.

Understanding where and how much the fault slipped can help with damage assessments, so we've made some preliminary estimates from S2 (data: doi.org/10.5281/zeno...)

New perspective article discussing how we define natural hazards in today's world.

Key message: a barrier between 'human' and 'natural' events is often unhelpful, and we must consider the interaction between multiple hazards in all cases.

The 'alternative' A628 route has its own set of landslides as well... We've got a small project (with @britgeosurvey.bsky.social) looking at some of these landslide-road interactions and disruptions to transport on a national scale.

Indeed, disasters are never natural. And sometimes, the hazards themselves are not either...
