Knowing how resilience changes in the aftermath of a shock is crucial to the targeting of effective humanitarian responses. Yet, heavy reliance on face-to-face household surveys often means that post-disaster evaluations of resilience are costly, time-consuming and difficult to coordinate. As a result, most quantitative assessments are either carried out via one-off snapshots or by combining surveys conducted years apart. Doing so severely restricts our understanding of the temporal dynamics of resilience, particularly as it relates to inter- and intra- annual fluctuations.

In this paper we examine how household's resilience to multi-hazard risk changes over time. To do so we combine two novel approaches. Firstly, we use a high-frequency mobile-phone panel survey to conduct remote interviews in Eastern Myanmar. Surveys took place every six weeks over a one-year period. Secondly, we adapt a self-evaluated subjective measure of resilience to allow it to be administered via mobile phone. Shortly after the first survey was conducted, monsoonal flooding affected the site, allowing for the effects of flood exposure on resilience to be compared over time.

Our findings reveal how self-evaluated levels of resilience fluctuate considerably over the course of a year. To probe the effects of the monsoon floods, we compare resilience scores between households directly and indirectly affected by flooding. Scores drop sharply for the first three months amongst directly affected households, before slowly converging up to a year later. We also compare the effects of flood exposure on different socio-economic groups, revealing how female-headed households are particularly affected in the aftermath of flooding. Insights from the study highlight the dangers of using one-off resilience surveys to measure resilience, and underscore the need for development actors to account for shorter-term changes in the design of resilience-building interventions. Lastly, our findings showcase the potential of methodological innovations in addressing many of the resource, time and logistical constraints of traditional resilience measurement practices.

知道冲击后的应变能力如何变化对于确定有效的人道主义对策至关重要。但是，严重依赖面对面的家庭调查通常意味着灾难后的复原力评估成本高昂，耗时且难以协调。结果，大多数定量评估要么通过一次性快照进行，要么通过相隔多年的调查相结合进行。这样做严重地限制了我们对弹性的时间动态的理解，特别是因为它与年际和年内波动有关。

在本文中，我们研究了家庭对多种灾害风险的抵御能力如何随时间变化。为此，我们结合了两种新颖的方法。首先，我们使用高频手机面板调查在缅甸东部进行远程采访。一年中每六周进行一次调查。其次，我们采用自我评估的弹性主观评估方法，以使其可以通过手机进行管理。进行首次调查后不久，季风性洪水影响了该地点，因此可以随时间比较洪水对弹性的影响。

我们的研究结果揭示了自我评估的抵御能力水平在一年中的波动情况。为了探究季风洪水的影响，我们比较了直接和间接受洪水影响的家庭之间的弹性评分。在直接受影响的家庭中，前三个月的得分急剧下降，直到一年后才逐渐趋于一致。我们还比较了洪水对不同社会经济群体的影响，揭示了洪水过后，特别是女性户主的家庭受到的影响。该研究的见解凸显了使用一次性弹性调查来衡量弹性的危险，并强调了发展参与者必须在建立弹性干预措施的设计中考虑短期变化。最后，
